Ohio Standards Connection : Standard: Earth & Space Sciences-Grade Nine- The Universe Benchmark A: Explain how evidence from stars and other celestial objects provide information about the processes that cause changes in the composition and scale of the physical universe. Indicator 2 Describe the current scientific evidence that supports the theory of the explosive expansion of the universe the Big Bang over 10 billion years ago.

Benchmark/Indicator Background. “Our Universe had its physical origin as a quantum fluctuation of some preexisting true vacuum, or a state of nothingness” Edward P. Tryon, ‘What Made the World?’ in New Scientist, March 8, 1984, p.16 “The fairest way to deal with the problem is not to fall back on authority (what eminent authorities believe or don’t believe) but to examine the evidence for oneself.” Geoffrey Burbridge, ‘Quasars in the Balance,’ Mercury, Vol.17, No.5 (A publication of the Astronomical Society of the Pacific, September-October 1988), p.140 “The initial origin of the world can be compared to a display of fireworks that has just ended: some few red wisps, ashes and smoke. Standing on a cooled cinder, we see the slow fading of the suns, and we try to recall the vanishing brilliance of the origins of the worlds.” Georges LeMaitre

Associated Standards: Ideas in this lesson are also related to concepts found in: Grade 9 Earth & Space, Benchmark A, Indicator 1 Grade 9 Scientific Inquiry, Benchmark A, Indicators 3, 5 & 6 Grade 9 Scientific Ways of Knowing, Benchmark A, Indicator 3, and Benchmark B, Indicators 7

Lesson Summary : Most students will likely know some information about the Universe and the Big Bang theory. In this lesson, students will build on this knowledge as they inquire and research scientific evidence on the Big Bang theory. Students will investigate further evidence from stars and other celestial objects that provide information about the processes that cause changes in the composition and scale of the physical Universe.

The lesson begins with a reading of a general overview of the Big Bang theory, and a table with questions on popular misconceptions of the Big Bang theory. A teacher led discussion and answer session of these thought provoking items ensues.

Using both the observational scientific evidences on the Big Bang theory and also the development history of the theory that are provided as a starting point, the students will then create a timeline that links the observational evidence with the development of the theory. A follow-up gallery walk of the timelines will next occur with the students writing in their journal key comparisons and contrasts (if any) between the timelines. Estimated Duration : 3 to 5 classroom periods

Pre-Assessment: Instructions to the Teacher: To start Part 1A- General Overview of the Big Bang theory, a vocabulary sheet will be handed out and briefly discussed in class. Fig 1 will then be handed out which the students are requested to read. The students should be informed that the purpose of the initial reading is to give the student a quick general overview of the topic and not to dwell on any specific details.

Fig 1 Initial Introductory Reading by the Student

Cosmology is the science that studies the origin, development, structure, and behavior of the Universe as a whole. As such, it is concerned with the large scale, both with respect to distance, and with respect to the past and future for the Universe.

Computer simulations play an essential role in comparing the predictions of theories for the content and early development of the Universe with observation and have become the primary method for testing such theories against astronomical data.

Remote sensing is a mainstay of observational Astronomy. Spectral measurements across the electromagnetic spectrum and the construction of spectral band images acquired by various kinds of telescopes operating in the visible (optical) range and/or with sensors that are tuned to other wavelengths (e.g., radio telescopes; gamma ray telescopes) are the principle data sources used to devise the modern cosmological models.

Over the last century, through a combination of speculation, theoretical insights, experiments and observations, cosmologists have converged on the Standard Consensus Model of the Universe, a mixture of the Big Bang picture and Inflationary cosmology to explain observations about the cosmos.

According to this picture, initially the whole Universe must have been contained in an infinitely curved, infinitely massive singularity (initial state of Universe). From this singularity, space and time sprung into being 15 billion years ago in a ‘Big Bang’. When the Universe emerged, it was filled with particles and radiation of nearly infinite temperature and density. Instants later, the Universe underwent a period of extraordinarily rapid expansion (‘inflation’) which made the Universe homogeneous (uniform) and flat (very low geometrical curvature), and which created fluctuations (tiny ripples in space) that seeded the formation of galaxies and large-scale structure. It appears that billions of years

after the Big Bang, following the formation of galaxies, the Universe was overtaken by some form of self repulsive dark energy that is causing the expansion rate to accelerate.

The hot Big Bang has been used to explain the observable properties of our Universe. However, there are some difficulties associated with the Big Bang theory. These difficulties are not so much errors as they are assumptions that are necessary but that do not have a fundamental justification. These problems are: The horizon problem, the flatness problem, and the magnetic monopole problem.

The Big Bang model, with no amendments, would tend to produce a Universe that is highly inhomogeneous (non uniform), with a warped and curved space, and no natural mechanism for making stars, galaxies and larger scale structures in the universe. Cosmologists have been trying to correct these deficiencies by amending the early history of the universe.

There are strong reasons to believe that the fluctuations which seeded the large scale structure of the Universe must have been primordial in origin, that is associated with some of the very earliest times after the Big Bang. At present there are two over-riding and competing paradigms for origin of large scale structure and fluctuations in the cosmic microwave background radiation:

1. Inflationary models. A period of extremely rapid expansion in the early Universe- known as Inflation- solves quite a number of cosmic enigmas. During Inflation small quantum fluctuations get amplified up to enormous cosmological lengthscales. These fluctuations later grow to form galaxies. Although Inflation has many attractive features, it is not yet a proven theory because many of the details still do no work out right in realistic calculations without making assumptions that are poorly justified.

2. Cosmic defect models. Supermassive topological defects (stable configurations of matter formed at phase transitions in the very early universe), like cosmic strings and textures, can form a cosmological phase transitions in the early universe. The defects form the seeds around which galaxies form. The cosmic string scenario predated Inflation as a realistic structure formation model. Only until recently, significant progress in understanding cosmic strings as seeds for large scale structure and cosmic microwave background (CMB) anisotropies (not the same in all directions) have been achieved.

A future goal by Cosmologists is to directly compare the quantitative predictions of these two competing paradigms to determine which, if either is consistent with the observational empirical data.

There have been many ideas over the last 20 years. Investigators have injected an imaginative new speculative research which intimates that physical reality could encompass far more than just the aftermath of ‘our’ Big Bang. This emphasizes the extent to which we may need to jettison common sense concepts, and transcend normal ideas of space and time, in order to make real progress. In the end though nature will be the final arbiter of truth.

Questions which the Big Bang/Inflationary model does not address: What occurred at the initial singularity? What is the ultimate fate of the Universe? What is the role of dark energy and the recently observed cosmic acceleration? Does time, the arrow of time, exist before the Big Bang? Or after the Big Crunch? END OF FIG 1

During the reading of Fig 1, students are to list those vocabulary words that pertain to Fig 1. In addition they are to write any comments they may have that tie into scientific evidences on the Big Bang theory of the Universe. Afterwards a teacher guided classroom discussion follows pertaining to the vocabulary and any general (not specific) questions the students may have on the overall reading.

During Part 1B- Conceptions/Misconceptions of the Big Bang Theory, the teacher hands out Table 1 shown below without the italicized [Answers] shown within the brackets at the bottom of the table. Table 1 Conceptions/Misconceptions on Standard Big Bang Theory

ANSWER: ANSWER: [ Public Misconception [ Experts Correct Conception of the Big Bang ] of the Big Bang ] END OF TABLE 1

The students are to individually write down at the bottom of the table which column is the correct conception and which column is the misconception of the Big Bang theory. The teacher collects the student’s completed Table 1, and then provides the answers. After the class is over, the teacher

of 17 Lesson #4 GREEN BDW 5/9/2018 DRAFT DRAFT DRAFT evaluates each student’s answers individually to gauge the student’s prior knowledge of the subject matter.

Fig 2 will then be handed out which the students are requested to read. This additional information should clarify most if not all of the questions previously covered in Table 1.

Fig 2 After Question Readings by the Student [56]

To the public, the Big Bang model means that the Universe began from a single point, underwent an explosion, and has been flying apart ever since. The analogy here is the Universe expands like dots on a balloon as the balloon is blown up. Imagine residing in a curved flatland on the surface of a balloon. As the balloon is blown up, the distance between all neighboring points grows: the two-dimensional Universe grows but there is no preferred center.

However the Big Bang is not an explosion at all. The Big Bang is the expansion or stretching of space. It is not that things are flying out from a point. Rather, all things are moving away from each other. It is like having an infinite rubber sheet with people sitting on it. Stretch the rubber sheet, and all the people move away from one another. Each thinks they are at the center of an explosion. It is an optical illusion-everbody moves away from everybody else and there is no center. Run the story going back and time and the sheet was more and more unstretched and the people were closer together. When everybody is so close they are on top of one another, this is the beginning of the Big Bang picture- the cosmic singularity. At that time, the Universe has nearly infinite density and temperature. END OF FIG 2

The teacher leads a guided classroom discussion to the readings of Fig 2 and any additional questions that the student may still have regarding the questions in Table 1. Again it should be noted that the students should be informed that the purpose of the readings and questions are to give the student a quick general overview of the topic and not to dwell on any specific details.

Scoring Guideline: This is an informal evaluation of the students understanding and knowledge. Teachers should make informal notations and record anecdotal comments about the level of understanding of the students.

Post-Assessment: Instructions to the Teacher: Transition into Part 2- Scientific Evidence that can support the Big Bang Theory

The teacher is to hand out photocopies of the following two Figures: Fig 3- Scientific Evidence that can support Big Bang Explosive Expansion Universe Theory Fig 4- Developments in the Standard Consensus Model of the Universe

Each student is to individually create two parallel timelines that links the information between the two tables together. One way this can be done is for the students to cut and paste the individual

of 17 Lesson #4 GREEN BDW 5/9/2018 DRAFT DRAFT DRAFT paragraphs of information from each table and then arrange them into chronologically order, while lining up the dates between the two parallel timelines.

The students are to compare the dates between: the observation of the scientific evidence; and the development of the model. They can then see how the model was modified as a result of the new observational evidence. They should note if there are any gaps or inconsistencies between the observational evidence and the development of the model.

A gallery walk will then occur with students writing in their journal notebook key comparisons and contrasts (if any) between each student’s timeline.

The teacher collects the students two timelines and then after the class is over evaluates each student based upon the Rubric.

Fig 3 Scientific Evidence that can support Big Bang Explosive Expansion Universe Theory [34], [20] and [Standard Textbooks such as Ref 47]

Note: The evidence for the Big Bang comes from many pieces of observational data that are consistent with the Big Bang. None of these prove the Big Bang, since scientific theories are not proven. Many of these observations are consistent with the Big Bang and some other cosmological models. The Big Bang model makes scientific testable hypotheses in each of these areas and the agreement with many of the observational data gives many cosmologists confidence in the model. [26].

The four key observational successes of the standard Hot Big Bang model are the following [55]:

 Expansion of the Whole Universe:

1912 Slipher- Dopler redshifts of spiral nebulae Slipher measured spectra from the nebulae (clouds of gas and dust in space), showing that many were Doppler-shifted, that is the frequency of light was affected by speed of the source (just as the frequency of sound alters for a passing train). By 1924, 41 nebulae were measured, and 36 of these were found to be receding away from us (redshifted).

1923-29 Hubble- proportionality between velocity and distance Hubble observed that, regardless of in which direction we look, galaxies are moving away from us at speeds proportional to their distance from us. The Hubble constant H is one of the most important numbers in cosmology because it may be used to estimate the size and age of the Universe. It indicates the rate at which the universe is expanding. The Hubble “constant” is not really constant because it changes with time and therefore should probably more properly be called the Hubble “parameter”. The Hubble constant is often written with a subscript “0” to denote explicity that it is the value at the present time

1964 Penzias & Wilson- the cosmic microwave background radiation (CMBR)

Discovery of the cosmic microwave background radiation. The temperature of this blackbody radiation is today measured to be T=2.73 Kelvin (that is, a rather cold -270 Celcius). Initial high temperature of the microwave radiation from the Big Bang has constantly been losing energy because its wavelength is stretched by the expansion of the Universe.

 Origin of the cosmic background radiation

1964 Penzias & Wilson - the cosmic microwave background radiation Working with a horn antenna at Bell Labs, Penzia & Wilson fortuitously discovered an isotropic (same in all directions) radio background, a relic left over from the primordial fireball. Observers detecting this radiation today are able to see the Universe at a very early stage on what is known as the ‘surface of last scattering’. Photons in the cosmic microwave background have been traveling towards us since the initial Big Bang.

 Nucleosynthesis of the light elements

1948 Sir Fred Hoyle - the light elements: Deuterium (D), helium-3, and helium 4 The Big Bang produces mostly the light elements hydrogen and helium. Theoretical calculations for these nuclear processes predict, for example, that about a quarter of the Universe consists of helium-4, a result which is in good agreement with current stellar observations. The heavier elements must be produced later in the interiors of stars and spread widely in supernova explosions. Thus, the existence of the heavy elements and the biology built on them, depends crucially on violent process taking place in stars and galaxies.[54]

 Formation of galaxies and large scale structure

The standard Hot Big Bang model provides a framework for understanding galaxy formation, but it does not tell us about the origin of the primordial fluctuations required.

1986 de Lapparent, Geller & Huchra- large scale structure, superclusters and voids Galaxy surveys of the Universe demonstrated the existence of structure such as huge bubbles, filaments and sheets that are of large scale size. Radio telescope survey of galaxies and quasars in the Universe indicate homogeneity (uniformity) is approached on scales nearly a billion light years in size.

1992 COBE Satellite- discovery of fluctuations in the CMBR. Discovery of small fluctuations (or ‘ripples of the edge of the universe’) in the very smooth cosmic microwave background radiation (CMBR) signal. These fluctuations are on the order of one part in 100,000 and are thought to be a snapshot at Cosmological time = 400,000 years of the primordial fluctuations that led to galaxy formation.

1995-1996 Hubble Space Telescope Early (Extreme distant/Extreme age) galaxies and quasars have also been observed by the Hubble Space Telescope raising serious doubts about current structure formation models. END OF FIG 3

Fig 4 Developments in the Standard Consensus Model of the Universe

Early 20th Century, Georges LeMaitre, Conceptual Big Bang Hypothesis Georges LeMaitre, a Belgian astrophysicist, came to be known as the ”Father of the Big Bang”. LeMaitre proposed, by using the second law of thermal dynamics as a starting point, that the Universe began as a single primordial atom of energy, (‘primordial egg’) something hot and dense that exploded, causing space to expand outward.

1948, George Gamow, Modern Big Bang Theory [10] George Gamow, a Russian-American physicist conceived of the big Bang theory as we know it today. He and his colleagues proposed that if a Big Bang had occurred, it would have left an afterglow, traces of background radiation that would still be present.

1984, Alan Guth- Inflation Theory [10] Inflation Theory modifies Big Bang theory during its initial expansion phase. It solves 3 known problems of the Big Bang theory. These problems are called: the horizon, flatness, and monopole problems. Now over 50 variations proposed [42]

1998, Adam Ries- Dark Energy, the expansion of the Universe is accelerating. Dark Energy component is required to augment the Standard Big Bang theory to account for the observation that the expansion of the Universe is accelerating. Using the Hubell Telescope, Riess and his colleagues found six supernovae (exploding massive red giant star) at different distances and thus from different eras in the Universe’s existence. By comparing each supernovae’s relative brightness or dimness to predicted values, it could be determined whether deceleration was occurring, and if so, when the changeover to acceleration occurred.

2002, Paul Steinhardt- “The Big Bounce” (Cyclic Models incorporating Big Bang) [56] The Cyclic Model of the Universe incorporates Big Bang theory without the need for Inflation and Dark Energy. Additionally it can also incorporate Topological Defect theory (e.g. cosmic strings, etc.). As it uses Big Bang theory, it successfully predicts the same evidence that Big Bang does.

October 2003 Jeff Weeks et.al., Finite soccer ball shaped closed Universe [57] NASA’Wilkinson Microwave Anisotrophy Probe’ (WMAP) was launched in 2001 to measure background radiation presumed to be left over from the Big Bang, and to produce a map of the temperature fluctuations. The current leading view is that the universe is geometrically flat, but infinite (open). This infinite universe would contain wavelengths of all sizes and have an infinite amount of matter. Mathematician Jeff Weeks, in a October 2003 resport said recent data from the WMAP shows only short and medium wavelengths, The longest wavelengths are missing and this points to a finite closed universe which does not have long wavelengths. The recent WMAP data shows that the geometric shape of this closed space may be based on a dodecahedron, a solid composed of 12 pentagons, similar to a soccer ball . It should be noted that the inflationary theory predicts unequivocally that the Universe should globally be exactly flat, thus this new data of a closed (non flat) Universe causes a discrepancy with the Inflationary theory.

12. The teacher is to hand out photocopies of the following two Figures: Fig 3- Scientific Evidence that can support Big Bang Explosion Expansion Universe Theory Fig 4- Developments in the Standard Consensus Model of the Universe 13. Each student is to individually create two parallel timelines that links the information between the two tables together. 14. One way this can be done is for the students to cut and paste the individual paragraphs of information from each table and then arrange them into chronological order, while lining up the dates between the two parallel timelines. 15.

The student is to compare the dates between: the observation of the scientific evidence; and the development of the model. The student should see how the model was modified as a result of the new observational evidence. The student should note if there are any gaps or inconsistencies between the observational evidence and the development of the model.

Differentiated Instructional Support: Instruction is differentiated according to learner needs, to help all learners either meet the intent of the specified indicator(s) or, if the indicator is already met, to advance beyond the specified indicator(s).

For students who struggle with the material covered in this lesson plan, partner them with others that possess understanding. Use material from a textbook, internet site, or other lesson plan that contains similar subject material. Encourage the struggling student to work on the material, preferable with the helper partner whenever possible, outside of instructional time. This can take place prior to or after the daily lesson, during shared study hall periods, before or after school, etc.. Possible use of supplemental multi-media software.

Extension: Part 3 Extended Learning- Additional scientific evidence on Stars and other Celestial Objects that provide information about the processes that cause changes in the composition and scale of the physical universe. Instructions to the Teacher:

For extended learning, each student has an option of researching and writing a report on one other additional scientific evidence that was not covered in this lesson cycle. See Attachment 1- General Student Research and Reporting Guidelines for specifics. The scientific evidence shall be about Stars and other Celestial Objects that provide information about the processes that cause changes in the composition and scale of the physical universe. Some possible examples are listed in Table 2. Note that other scientific evidences may be included or substituted from those shown at the teacher’s discretion. As an option, the student may also explain whether the scientific evidence can be interpreted to fit the model or are they an anomaly?

in the Composition and Scale of the Physical Universe.

CELESTIAL SCIENTIFIC EVIDENCE OBJECT(S) Sun: Sun’s red shift not Doppler [5], [29] Stars: Nearby stars in Milky No population III first 1926 Eddington’s Way, & other generation stars calculation 3 degree galaxies older than containing only H & Kelvin temperature age of universe He of space due to [1], [13],[39] [51] radiation of starlight [13], [17] , [25] Quasars: Quasar discordant Faraway Quasars dated Quasar e.g. PKS redshift companions at 15 BY, since 2000-330 is bright [28] redshift = 400% as 100 trillion suns [52] and billions of times more massive if redshift was due to great distance. [47] Interstellar Gas: Interstellar gas contains variety of heavier elements beyond H & He [50]

Galaxies: Earliest Quasars and galaxies have substantial metal content [17] (Note: These scientific evidences may be interpreted by some to conflict with the Big Bang explosive expansion Universe theory [17], [16], [18], [40], [41]. See Ref [9] for rebuttal of errors on attacks on Big Bang)

Copies of all references used by the student shall be presented along with the written report. After the reports are turned in the student shall prepare a brief presentation on their findings. The teacher will then conduct a teacher directed discussion on the additional scientific evidence. Allow 1 week non classroom time for the students to prepare the report as homework, and minimum 2 minutes, maximum 3 minutes for each student presentation, with a maximum 2 minute class discussion immediately following each presentation. Allow 1 class period.

Instructions to the Student: Your teacher can help guide you on potential reference sources to use or suggest key words/phrases to try when using internet web search engines.

Follow Attachment 1 guidelines on researching and reporting. If you have any questions regarding what format to use in your presentation, ask your teacher to help you in choosing an acceptable model to follow.

Homework Options and Home Connections: Part 4 Observational List on Characteristics of the Universe

Instructions to the Teacher: Research one of the following characteristics of the Universe (Fig 5). Note that other characteristics may be included or substituted from those shown at the teacher’s discretion. Write a brief one page paragraph on one or more of the following characteristics as shown in the table below. Assume one half a class period to discuss any questions relating to the homework.

Fig 5 Observational List on Characteristics of the Universe: (Note: Source is from Ref [1] unless noted otherwise)

1) The majority of heavenly objects, moving in groups, are separate from each other. 2) Heavenly objects are receding from us. The further away they are from us, the higher the speed with which they are receding. 3) Objects with red shift coexist with objects with blue shift, although the number between them is no comparison. In other words, we do find movement of heavenly material collections, contradicting the movement stated in 2). 4) A large quantity of heavenly objects, such as planets, stars, and collections of such objects, such as multiple star systems and galaxies, are spinning while also making translational movements. Furthermore, in relation to any appointed direction in the universe, the axes of these spinning entities are oriented as randomly as one can imagine. 5) The distribution of mass quantity in space is roughly homogeneous and isotropic. However, the homogeneous mass distribution is also repetitively interrupted by distribution of layers. 6) There exists an isotropic background noise, which is supposed to be one form of radiating energy of an electromagnetic nature. 7) The existence of electrons and positrons in intergalactic space is observed from the Compton Gamma Ray Observatory Satellite [5]. 8) Intergalactic space is not a vacuum but is filled with clouds of high velocity gas that contains molecular hydrogen [5], [25], [29].

General Tips: The evidence for the Big Bang comes from many pieces of observational data that can be consistent with the Big Bang. None of these prove the Big Bang, since scientific theories are not proven. Many of these observations are consistent with the Big Bang and in addition also with some other cosmological models not included in this lesson due to the Indicator specific requirements.

Attachment 1 General Student Research and Reporting Guidelines:

1. Teacher is to provide topic and question. 2. Suggested reference source(s) and key word(s)/phrase(s) for web search engine will be provided by teacher. 3. Student is to evaluate the usefulness, and whenever possible the credibility, validity and possible bias/slant of data, information and sources (primary and secondary). Teacher is to act in a review capacity during this process. 4. The credentials and past reliability track record of both the author and publisher should be taken into consideration in evaluating the reference source. One should note though that some important paradigm shifts in the past were first discovered by investigators working outside of their specialty field of formal education, e.g. Charles Darwin was a divinity school graduate. Also, from 1903 until 1908 the two bicycle mechanics Wilbur and Orville Wright were rejected by Scientific American for their 1903 claim to have successfully built and flown a heavier than air flying machine. 5. Critical thinking skills should include a check by the student for potential errors in logical reasoning and/or extrapolation used in the reference source. 6. Where appropriate and available, contrary/anomalous information should also be evaluated in order to provide an intellectually honest and balanced perspective. 7. An attempt should be made to include some non-American references that provide written information available in the English language. 8. Student should utilize investigative inquiry methods appropriate to the type of question being researched. 9. Research should be linked to relevant scientific theory/knowledge, and be germane to the topic so as to stay on target with the indicator and benchmark. 10. The student should use and describe a logical, coherent and explicit line of reasoning. 11. Information from various resources should be organized, and the sources selected should be appropriate to support the central ideas, concepts and themes. 12. Students should produce reports that give proper credit for sources. 13. The findings communicated on the substance and processes should include using the proper modes and media appropriate to the nature and/or type of information.
