Science Fair projects should have a display board or power point/web site and logbook. The Project ID # assigned by the teacher should be placed: 1. on the front of the display board in the top right corner, and 2. on the front of the log book. We require that projects adhere to ISEF regulations. Regulations and documents can be access at http://www.societyforscience.org/isef/document. These regulations mandate that proper care must be taken to insure the safety of the student researcher, any human subjects, and the public, as well as proper treatment of vertebrate animals that are used in experimental studies. Students must work under the guidance of an adult sponsor (typically a teacher), and possibly other specialists depending on the nature of the student's project. Projects that involve human subjects, vertebrate animals, potentially hazardous biological agents (bacteria, etc), tissues, or hazardous chemicals MUST be approved by the SRC/IRC committee before the student begins experimentation. Projects requiring IRB/ISEF forms must have a copy of the IRB form in the logbook.  ISEF forms are at the end of the packet for those students who choose project topics that require them.

Experiment Project steps

Step 1: Formulate a Hypothesis to answer question. Students will first design a testable question. Students will then come up with a testable hypothesis to answer the question that has been asked on the chosen topic. Step 2: Design experiment- variables Students will determine what the independent and dependent variables are for the experiment. This will guide students as to what the experiment will look like. Step 3: Determine materials and procedures Students will determine what materials will be needed for the experiment and acquire the needed materials. Students will also plan out the step by step procedure for the experiment before carrying it out. Step 4: Experiment- collecting data (trials) Student will perform the experiment at home. Student will collect data in data tables and keep a journal record of what was done at each step. Step 5: Analyze data, conclusion Student will look at the data collected and make tables and graphs. Students will then analyze the data and write a results paragraph. Once these are completed the student will then write a conclusion paragraph.

Step 1, part 1 Name______Period____Date______Question The first step in choosing a science fair experiment is choosing a testable question. In your science fair experiment, you will search for cause and effect relationships. In other words, you will design an experiment so that changes in a factor will cause an item to vary in a measurable or observable way. The science fair question must include the independent variable and dependant variable. Correct spelling and grammar are a must.

Examples: How much water flows through a faucet with different sized openings? Independent variable- (What I changed): size of the faucet opening Dependant variable- (What I observed/measured) volume of the water that flowed out of the faucet.

What is the effect of the kind of copper wire on the number of paper clips that an electromagnet can lift? Independent variable- (What I changed): type of wire Dependant variable- (What I observed/measured): number of paper clips the electromagnet picked up

Does the design of the catapult arm affect the accuracy of the toss of the projectile? Independent variable- (What I changed): different arm design for the catapult Dependant variable- (What I observed/measured): distance the object is from the target

Question check list 1. Independent variable 2. Dependant variable 3. no pronouns 4. written in the third person 5. question mark included 6. correct spelling (affect-verb, effect-noun) 7. correct tense (present/future)

Page | 8 Option B: Experiment

Place the correct, edited version of the question in the box.

Step 1, part 2 Name______Period____Date______Hypothesis

Hypothesis means “before the idea”

It is best to think about how a change of one factor/variable might affect another factor or outcome.

It is a plan how to solve a problem, a plan on how to answer your question.

It should state the variable you are planning on changing and how it might affect the outcome.

It should contain a verb such as …determined, measured, tested, observed, calculated, or examined.

1. the plan 2. independent variable (the one being tested) 3. affect on outcome 4. verb 5. correct spelling 6. correct grammar (no pronouns)

Place your final, edited draft of hypothesis in box below.

Page | 9 Option B: Experiment

Step 1, part 2 Name______Period____Date______Hypothesis 2

Your hypothesis should have… 1. the plan 2. independent variable (the one being tested) 3. affect on outcome 4. verb (determined, measured, counted, tested, observed, calculated, examined etc.) 5. correct spelling 6. correct grammar (no pronouns-me, my he, she, etc.)

Now look at what you already have. Now rewrite it so it is in one of the following formats.

Choice 1- If the (independent variable) is changed, then the affect on ______can be (verb) Choice 2- By changing the (independent variable), then the affect on the ______can be (verb) Choice 3- When changing the (independent variable), the affect on the ______can be (verb)

You can Change the words around but keep the basic format. ~Change of (independent variable), affect on results can be (verb)

Place your final, edited draft of hypothesis in box below.

Display Board, Prezi, or Website- All Grade levels

The display is your advertisement for your project. Think about your favorite bill board or commercial. What do you like about them? What makes them stand out? Now think about how you can make your display board, Prezi, or web site stand out. Display Boards: 1. Exhibits cannot exceed a depth of 30 inches, width of 48 in and a height of 9 feet. Prezi/Web Site: 2. Must have some way of displaying exhibit. Must be Emailed to your Science teacher. Both Display Board/Prezi/Web site: 3. All lettering should be readable from four feet away…this means larger than 12 font. 4. Headings and titles should be at least 1 inch in height. 5. Spelling should be carefully checked. 6. Consider artistic appeal by considering boarders, complimentary colors and display materials and equipment. 7. Plan your time carefully. An excellent display will take time to obtain materials and implement your design. 8. The project should include materials and equipment used but may not include:  Plants  Microbes  Animals  Sharp objects  Lasers  Powder  Fuels, food, chemicals, liquids  Soil  Glass

9. The display must include: Title 1. Problem, Question, or Purpose 2. Hypothesis 3. Procedures (methods and materials listed) 4. Results with data, graphs, analysis of data 5.

Page | 15 Option B: Experiment

Step 4 guidelines Writing up your Results- All grade levels Your result should be written in a brief paragraph of what you discovered while conducting your experiment.

 Write a topic sentence stating the independent and dependant variables referencing appropriate tables/graphs. There are several ways to write a topic sentence as long as the needed information communicated. Example- The effect of different number of batteries wired in a series on the force of the motor is shown in Table1.1, Table 1.2, Graph 1.1 and Graph 1.2

 Compare each test with the other tests done. Example- Twelve washers were lifted by two batteries in test one and fifteen washers in test two. Twenty washers were lifted by three batteries in test three and nineteen washers in test four.

 Write a sentence describing the range of data Example- The range in number of washers that two batteries in a series was more than the range for three batteries wired in a series. As the number of batteries increased the range decreased.

 Write a sentence stating how the data supports or disproves your hypothesis. Example- The data supported the hypothesis that the effect of the number of batteries on the force exerted by a motor could be determined. Example- Since different numbers of batteries affected the force of the motor, the hypothesis that the effect of the number of batteries on the force exerted by a motor could be determined was supported.

Step 5 guidelines Writing a Conclusion A conclusion is the last section of a report of an experiment. It is written in third person, past tense, and typed.

 The purpose- Example- The purpose of this experiment was to find the effect of the independent variable on the dependant variable.  Major findings Example-In test one… (explain findings). In test two…, in test three…  Trends Example A- The effect of the independent variable on the dependant variable showed a (positive trend, negative trend, no trend, no correlation, constant) Example B- As the independent variable increased/decreased the effect on the dependant variable showed a (positive trend, negative trend, no trend, no correlation.)  Possible explanations for findings Example- A possible explanation for these findings is that the molecules move faster in warm water, causing them to strike the tablet more frequently and tear it apart more quickly.  Compare other researchers’ findings to your findings Example- The findings agree with the solubility rule that solids dissolve faster in warm solvents as found in the Handbook of Chemistry and Physics.  Discuss possible sources of error such as human and experimental errors Example- Variation in data could have been caused by the release point of the car not being exactly the same each trial which caused the time to be too high on some of the trials and too low on others.  Recommendations for further study Example- Additional experiments could be conducted to determine the… This experiment could be improved by…

Writing an abstract An abstract gives the essence of the project in a brief but complete form-it should not exceed 250 words. Judges and other should have a fairly accurate idea of the project from reading the abstract. Details and discussions should not be included in the abstract (put those into the research report or on the display board.) The abstract does not include acknowledgements. The abstract needs to be typed Use 12 point font Do NOT type the word abstract at the top- your title should be at the top of the abstract. One copy of the abstract goes into the log book. One copy of the abstract goes onto the Display board. The abstract should have the following parts: a. Purpose of the experiment- Why are you conducting the experiment? (rationale), What do you hope to learn? (question), What do you think will happen? (hypothesis) b. Procedures used- A summery of the key points and an overview of how the experiment was conducted. Only include procedures done by you the student. Do not give details about the materials used unless it greatly influences the procedure or had to be developed to do the investigation. c. Data- This section should be a written version of key results that lead directly to the conclusion you have drawn. It should not include any data tables or graphs. d. Conclusions- This section should be briefly described. The summary paragraph should reflect on the process and possibly state some applications and extensions of the experiment. Sample Abstract- The purpose of this project was to identify whether a photovoltaic panel that follows the sun’s movements will collect more energy than a panel that is in a fixed position. The testing period for this experiment spanned six hours a day for five days, from 10:00am to 4:00pm, for a total of 30 hours. The fixed system and tracking system were tested at the same time every hour. The building material for the fixed system and the tracking system is the Lego Mindstorms Robotic kit. This kit included building pieces and a microcomputer. A sensor was developed to locate the direction of the sun. A photovoltaic panel was mounted on a motor-driven support that turned to follow the sun’s movement. A program was developed to activate the motor when movement was necessary. The testing results showed that the sun tracking system did, indeed, collect more volts than the stationary panel. The tracking system collected nine percent more volts than the stationary panel. This experiment demonstrated that photovoltaic panels that track the sun are more efficient than panels that do not track the sun. One aspect of this experiment that should be taken into consideration by scientists is whether the motor uses a lot of energy or not. There are two contributions made by this project. First, it verifies that tracking solar power is going to become even more viable for the future. Secondly, it shows that there are still more ways to improve clean energy sources.
