Abstract. An abstract is an abbreviated version of your final report


 

 

Question, variables, and hypothesis.


 

 

Background research. This is the Research paper you wrote before you started your experiment.


 

 

Materials list.

Materials

·         D battery

·         Insulated 22G wire

·         2 large-eyed, long, metal sewing needles (the eyes must be large enough to fit the wire through)

·         Modeling clay

·         Electrical tape

·         Hobby knife

·         Small circular magnet

·         Thin marker

Electric Motor Materials


 

 

Experimental procedure.

1.    Starting in the center of the wire, wrap the wire tightly and neatly around the marker 30 times.

2.    Slide the coil you made off of the marker.

3.    Wrap each loose end of the wire around the coil a few times to hold it together, then point the wires away from the loop, as shown:

Electric Motor Armature

What is this? What is its purpose?

4.    Ask an adult to use the hobby knife to help you remove the top-half of the wire insulation on each free end of the coil. The exposed wire should be facing the same direction on both sides. Why do you think half of the wire needs to remain insulated?

Electric Motor Removing Insulation

5.    Thread each loose end of the wire coil through the large eye of a needle. Try to keep the coil as straight as possible without bending the wire ends.

Electric Motor Needles

6.    Lay the D battery sideways on a flat surface.

7.    Stick some modeling clay on either side of the battery so it does not roll away.

8.    Take 2 small balls of modeling clay and cover the sharp ends of the needle.

9.    Place the needles upright next to the terminals of each battery so that the side of each needle touches one terminal of the battery.

Electric Motor with Clay

10. Use electrical tape to secure the needles to the ends of the battery. Your coil should be hanging above the battery.

11. Tape the small magnet to the side of the battery so that it is centered underneath the coil.

Completed Electric Motor

12. Give your coil a spin. What happens? What happens when you spin the coil in the other direction? What would happen with a bigger magnet? A bigger battery? Thicker wire?

 


 

 

Data analysis and discussion. This section is a summary of what you found out in your experiment, focusing on your observations, data table, and graph(s), which should be included at this location in the report.


 

 

Conclusions.


 

 

Ideas for future research. Some science fairs want you to discuss what additional research you might want to do based on what you learned.


 

 

Acknowledgments. This is your opportunity to thank anyone who helped you with your science fair project, from a single individual to a company or government agency.


 

 

Bibliography. List all the sources used reference, no one likes plagiarism.

Grade Level: 6th to 8th; Type: Social Science

This experiment will evaluate if weather can impact the way people feel.

It has long been believed that weather has influence over people's mood and behavior. In this experiment, the emotional disposition of many test subjects will be evaluated on rainy and sunny days to find out if weather can really impact the way people feel.

  1. Create a survey to give your test subjects that analyzes their current mood. Example questions could include: Rate your current level of stress on a scale of 1 to 10. How many fights/disagreements have you had today? How many times have you honked your horn while driving in your car today? On a scale of 1 to 10, how satisfied are you with your life? How many good things have happened to you today? On a scale of 1 to 10, rate your current energy level.
  2. Wait for a sunny day and ask many test subjects to take your survey. Give the survey at the end of the day to ensure that test subjects have been exposed to the weather long enough for it to have an effect. Include males and females in many different age groups.
  3. Ask the same test subjects to repeat the survey at the end of an overcast, rainy day.
  4. Analyze the surveys taken by each test subject. Do you observe any patterns in your test subjects’ response to each survey? Do responses differ dramatically between the two days? Are there certain groups of people that seem to be more influenced by the weather?

Grade Level: 4th to 8th; Type: Social Science

Objective:

This experiment explores whether computer screen and text color affect retention and if people subconsciously prefer combinations of colors that help retention.

Research Questions:

Materials:

Experimental Procedure

  1. Develop several simple retention tests: lists of words that the test subject will study and then recall. The lists should all be different but equally difficult.
  2. Type the lists of words so that each list appears on a different colored screen and with different colored text. Include a range of light and dark, vibrant and subdued colors.
  3. Allow the test subject to study a list of words for 30 seconds.
  4. Take the computer away and ask the subject to name as many of the words as he can remember.
  5. Repeat the memory test using all combinations of screen and text colors.
  6. Record the number of words recalled for each color combination.
  7. Ask the subject if there was any screen/text color combination(s) that he preferred.
  8. Analyze the results. Did certain combinations of screen and text colors lead to a consistently higher number of words being retained? Is there any correlation between preferred colors and retention?

Terms/Concepts: screen color, text color, retention, preference
