OF GARY Gary, Indiana 1968 O 1 PREFACE The teaching of science in t elementary school is a responsibility of major significance. Through our efforts pupils should be helped to gain an understanding of science in the development of our culture. Likewise, we should emphasize the development of the ability to write and recognize social uses of science in daily life. In developing the ability to under- stand their natural environment, the pupils must also have a complete understanding of the process involved. There is a need to improve teaching and learning in science contin- uously. New materials of instruction, new teaching approaches, and the continuing responsibility to meet the individual needs of students place great demands on all professional staff members to appraise the quality of teaching and learning in science. This publication represents an effort on the part of staff members within our school system to assist all staff members in improving the teaching and learning in science. It is hoped that all staff members who use this publication will find it to be of value. orman R. Turchan eneral Elementary Supervisor 2 ACKNOWLEDGMENTS wish to express appreciation to the members of the Elementary Science Materials Committee for their extra effort in the preparation of this publication.

Starr, 3rd Elementary Supervisor 3 TABLE OF CONTENTS page THE SUN, EARTH AND MOON Initiatory Activities 1 Developmental Activities-Concepts: Al]. objects occupy space The sun is a nearby star that is the center of a large system of heavenly bodies that revolve around it 2 We seldom see the sun on rainy and cloudy days. Shadows form when things block the light 3 The sun is always shining. It is day when our part of the earth faces the sun. It is night when our part of the earth is turned away from the sun 4 Shadows are made by the sun changing during the day. The re- lationship between shadows and the sun is of great importance in the study of time, seasons, and directions 5 The sun gives us warmth and light; helps make rain which supplies water to plants and animals 5 The amount of energy received by a section of the earth depends upon the angle at which the sun's rays strike the ground 8 All satellites, natural or artificial, travel around the sun in fixed orbit 9 The earth is a natural satellite of the sun. The earth's cir- cumference is 25,000 miles 9 The rotation of the earth causes day and night 12 The tilting of the earth's axis causes sunlight to strike the earth at different angles as the earth revolves around the sun 12 Different weather conditions and different plant and animal habits come with the changing of the seasons 14 The sun shines on the moon' 17 The moon is a natural satellite of the earth. One revolution of the moon around the earth takes a month 19 Much is already known about the moon 20 The moon's surface contains craters of unknown origin 21 The motions of the earth and the moon can align them in such a way that their position relative to the sun will cause an eclipse 22 The earth's rotation makes the sun appear to move across the sky 25 Certain words have meaning only in relation to other words-- discovering relativity in temperature 26 The appearance of objects is relative 26 Motion is a relative phenomenon 27 Distances to stars can be determined by studying their light. The farther away a light is, the fainter it seems. Therefore, distances can be calculated by the relative brightness of stars 28 TABLE OF CONTENTS (Continued) The apparent path of the sun is called the ecliptic 29 The path of the earth around the sun is an ellipse 30 STARS AND PLANETS Initiatory Activities 32 Developmental Activities- Concepts: Scientists differ in their theories about the origin of the Solar System 32 The planets differ in size 33 Our Solar System is part of the Milky Way Galaxy, a tremendous grouping of stars, which is only one of many galaxies 35 The universe is made up of many star systems of galaxies 36 Planets, planetoids (asteroids), moons, comets, a4,1 meteors are all part of the sun's family, the Solar System 37 Stars shine during the day, but we don't see them because their light is obscured by the brightness of the sun 38 The earth is the third planet from the sun 39 Light waves need no carrier; they travel across a vacuum 40 Heat energy can travel through a vacuum, such as space 41 A light year is a convenient unit to measure distances in space; it is the distance light travels in one year 41 EXPLORING SPACE Initiatory Activities 45 Developmental Activities - Concepts: Astronomers use a spectroscope to determine the chemical com- position of the stars and of the atmosphere of other planets 46 The Doppler effect is the name given to the shift of the position of spectral lines when the light source is either receding from or approaching the spectroscope 48 Some space probes carry instruments such as the magnetometer, to detect the magnetic fields around other planets 49 'There may be life on other planets 50 The earth pulls things down toward it. This is called the earth's gravity 51 "Down" is toward the earth. "Up" is away from the earth 52 Everything has gravitation. The more mass to a substance the stronger the gravitation. The greater the distance between two things the weaker the gravitation between them 54 The earth pulls all objects toward its center 54 If a great enough force is exerted in a direction opposite to the gravitational force exerted by the earth, an object can rise 55 To overcome the earth's gravitational attraction, large amounts of energy must be expended 56 Inertia keeps moving things going 57 Inertia is a force that keeps things that are at rest where they are 60 TABLE OF CONTENTS (Continued) How can you demonstrate the centrifugal effect?.. 61 Fetween the earth's two magnetic poles there is a magnetic field including the earth and the poles themselves.... 62 A magnetic compass worked because the earth is a magnet having two ends I. MI 62 If a satellite moves fast enough, it is not pulled down by the earth's gravity OOOOOOOOO 63 Light is composed of waves of differing lengths; each color is a wave of a different length 64 A prism can spread light into a spectrum 65 Rocket engines work on the principles described by Newton's third law of motion which states, that for every action there is an equal and opposite reaction . 66 The thrust of a rocket propellant is the amount of force it produces 71 The mass ratio of a rocket is a measure of the final speed it will achieve. The higher a rocket's mass ratio, the greater will be its speed 73 There are several types of rocket propellants; liquid, solid, and hypergolic 73 Inertia is the tendency of a body at rest to remain at rest or of a body in motion to remain in motion in the same direction unless acted upon by some outside force 74 A spacecraft's flight path is determined by its inertial tendency and the gravitational forces acting upon it 75 A spacecraft may travel in one of four possible flight paths- a circle, an ellipse, a parabola, or a hyperbola.,.

TRANSIENT LUNAR PHENOMENA: REGULARITY AND REALITY Arlin P. S. Crotts Department of Astronomy, Columbia University, Columbia Astrophysics Laboratory, 550 West 120th Street, New York, NY 10027, USA Received 2007 June 27; accepted 2009 February 20; published 2009 April 30 ABSTRACT Transient lunar phenomena (TLPs) have been reported for centuries, but their nature is largely unsettled, and even their existence as a coherent phenomenon is controversial. Nonetheless, TLP data show regularities in the observations; a key question is whether this structure is imposed by processes tied to the lunar surface, or by terrestrial atmospheric or human observer effects. I interrogate an extensive catalog of TLPs to gauge how human factors determine the distribution of TLP reports. The sample is grouped according to variables which should produce differing results if determining factors involve humans, and not reflecting phenomena tied to the lunar surface. Features dependent on human factors can then be excluded. Regardless of how the sample is split, the results are similar: ∼50% of reports originate from near Aristarchus, ∼16% from Plato, ∼6% from recent, major impacts (Copernicus, Kepler, Tycho, and Aristarchus), plus several at Grimaldi. Mare Crisium produces a robust signal in some cases (however, Crisium is too large for a “feature” as defined). TLP count consistency for these features indicates that ∼80% of these may be real. Some commonly reported sites disappear from the robust averages, including Alphonsus, Ross D, and Gassendi.

  • Water on the Moon, III. Volatiles & Activity

    Water on the Moon, III. Volatiles & Activity

    Water on The Moon, III. Volatiles & Activity Arlin Crotts (Columbia University) For centuries some scientists have argued that there is activity on the Moon (or water, as recounted in Parts I & II), while others have thought the Moon is simply a dead, inactive world. [1] The question comes in several forms: is there a detectable atmosphere? Does the surface of the Moon change? What causes interior seismic activity? From a more modern viewpoint, we now know that as much carbon monoxide as water was excavated during the LCROSS impact, as detailed in Part I, and a comparable amount of other volatiles were found. At one time the Moon outgassed prodigious amounts of water and hydrogen in volcanic fire fountains, but released similar amounts of volatile sulfur (or SO2), and presumably large amounts of carbon dioxide or monoxide, if theory is to be believed. So water on the Moon is associated with other gases. Astronomers have agreed for centuries that there is no firm evidence for “weather” on the Moon visible from Earth, and little evidence of thick atmosphere. [2] How would one detect the Moon’s atmosphere from Earth? An obvious means is atmospheric refraction. As you watch the Sun set, its image is displaced by Earth’s atmospheric refraction at the horizon from the position it would have if there were no atmosphere, by roughly 0.6 degree (a bit more than the Sun’s angular diameter). On the Moon, any atmosphere would cause an analogous effect for a star passing behind the Moon during an occultation (multiplied by two since the light travels both into and out of the lunar atmosphere).

    Facts & Statistics About the Project

    1 Hubble’s 15th Anniversary – Facts about the ESA project Introduction 24 April 2005 marked the 15th anniversary of the launch of the NASA/ESA Hubble Space Telescope. As an observatory in space, Hubble is a major project that has made an enormous impact both in terms of scientific output and in its immediate public appeal. Hubble has exploited its unique scientific capabilities in regions where no other instruments can compete. The telescope consistently delivers super-sharp images and clean, uncontaminated spectra over the entire near-infrared to ultraviolet regions of the electromagnetic spectrum. This has opened up new scientific territory and has resulted in many paradigm-breaking discoveries. Exquisite quality images have enabled astronomers to gain entirely new insights into the workings of a huge range of different astronomical objects. Hubble has provided a visual overview of the underlying astrophysical processes taking place in these objects, ranging from planets in our Solar System to galaxies in the young Universe. The renowned British astronomer Malcolm Longair writes in the preface to ESA’s anniversary book: ”The Hubble Space Telescope has undoubtedly had a greater public impact than any other space astronomy mission ever. The images included in this beautiful volume are quite staggering in the detail they reveal about the Universe we live in and have already become part of our common scientific and cultural heritage.” The project Many people agree that the long-term well-being and cultural development of European citizens depends on research and technological development. Information about science and scientists is a vital component of the scientific process, but the competition for attention in today’s mass-media market is fierce.

    Metallic Species, Oxygen and Silicon in the Lunar Exosphere: Upper Limits and Prospects for LADEE Measurements Menelaos Sarantos,1,2,3 Rosemary M

    JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 117, A03103, doi:10.1029/2011JA017044, 2012 Metallic species, oxygen and silicon in the lunar exosphere: Upper limits and prospects for LADEE measurements Menelaos Sarantos,1,2,3 Rosemary M. Killen,3,4 David A. Glenar,3,5,6 Mehdi Benna,7 and Timothy J. Stubbs3,7,8 Received 29 July 2011; revised 20 December 2011; accepted 22 December 2011; published 13 March 2012. [1] The only species that have been so far detected in the lunar exosphere are Na, K, Ar, and He. However, models for the production and loss of species derived from the lunar regolith through micrometeoroid impact vaporization, sputtering, and photon-stimulated desorption, predict that a host of other species should exist in the lunar exosphere. Assuming that loss processes are limited to ballistic escape, photoionization, and recycling to the surface, we have computed column abundances and compared them to published upper limits for the Moon. Only for Ca do modeled abundances clearly exceed the available measurements. This result suggests the relevance of some loss processes that were not included in the model, such as the possibility of gas-to-solid phase condensation during micrometeoroid impacts or the formation of stable metallic oxides. Our simulations and the recalculation of efficiencies for resonant light scattering show that models for other species studied are not well constrained by existing measurements. This fact underlines the need for improved remote and in situ measurements of the lunar exosphere such as those planned by the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft. Our simulations of the LADEE neutral mass spectrometer and visible/ultraviolet spectrometer indicate that LADEE measurements promise to provide definitive observations or set stringent upper limits for all regolith-driven exospheric species.
