First Grade Science Fair Projects




This page will show you some simple experiments and ideas for first grade science fair projects. Even though simple to do, they show you important principles of science. No better time to start exploring the fascinating world of science than the first grade.

 

Density Experiment

Fill a glass or small plastic container 1/2- 2/3 full of tap water. Place an egg in the water and see if it floats or sinks. It most likely will sink.

Remove the egg and stir in a teaspoon of table salt until it dissolves. Try the egg again to see if it floats now. if it still sinks, then remove again and stir in more salt. Keep testing and adding more salt until the egg floats.

Why does the egg float after adding a certain amount of salt? Hint: you have changed the density of the water. A volume of the salt water equal to the volume of the egg now is heavier than the egg. Thus the egg can't displace it and has to float.

Try repeating the experiment using sugar instead of salt.

 


The Lever experiment

first grade science fair projects This first grade science fair project demonstrates the function of a lever. You will need a round pencil, an ice cream stick, a piece of tape, and some small coins like nickles. A craft stick works well also in place of the ice cream stick.

Place a flat side of the stick across the center of the pencil. At first try placing about 3/4 of the stick across and then tape it in place. The pencil should roll easily when placed on a flat surface allowing the stick to rock up and down.

I placed three nickles at the end of the short piece of the stick. When I placed one nickle at the edge of the long end it lifted the three nickles. It will depend on how much length of the stick you placed across the pencil whether it lifts three nickles by the way.

If you changed the position of the stick on the pencil making one side even shorter it will lift more weight. If you make it longer it will lift less. If its perfectly centered across the pencil it will be balanced when the same weight is applied to each side.

You can do this experiment using a board across a brick or across a small round piece of wood.. You may be able to lift an adult two or three times your weight. Aren't first grade science fair projects fun?






More Ideas For First Grade Science Fair Projects

These topic ideas may well be appropriate for students in higher grades. Also you may see some of these ideas listed on other pages of this site as well.
  1. Will adding salt to water affect how fast it evaporates? Will sugar affect the rate of evaporation of water?

  2. Demonstrate vapor pressure. Fill a plastic two liter drink bottle about a quarter full with water. Squeeze in the sides and put the cap on tightly. Place it in the hot sun for a while and see what happens.

  3. Add up the nutrition values for an average breakfast you eat. The amount of protein, vitamin c, etc. compare this with the reccomended allowance for a person your age.

  4. Do cheaper brands of orange juice contain the same amounts of vitamin c as name brands?

  5. Make a compass from a needle and a cork.

  6. Which common products clean a tarnished penny better? Orange juice, grapefruit juice, apple juice, vinegar, baking soda dissolved in water?

  7. Show how a solar eclipse occurs. A lunar eclipse.

  8. Test whether white or dark objects get hotter in the sun.

  9. Explain and diagram the phases of the moon.

  10. How do snakes and other reptiles stay cool in the summer?

  11. Make different designs of paper airplanes and see which fly best. Do the size of the wings make it glide longer?
