the experiments

We had our Fifth Homeschool Science Fair a couple of weeks ago, and I’d like to share the experiments Lucas and Siena did.

Lucas’s experiment this year:

  • Question: How long can you stay in the air when you jump?
  • Hypothesis: I thought I could jump higher with both feet together.



So Lucas timed (with a special equipment) all four of us in the family, and 3 other friends.  We all jumped with both feet.  With the left foot.  And with the right foot only.

He timed us, making great calculations (practicing lots of math!) and made a bar graph.

  1. Jumping with both is better.
  2. Boys and girls jump the same.
  3. Left leg jumping is harder.

Now, Siena’s experiment: 

  • Question: Do muscles work better when they are cold or warm?
  • Hypothesis: The warmer muscles are the better they work.

DSC_0001-small DSC_0038-smallSiena tested the hand muscles.  She tested her hypothesis by doing as many grips we could in 10 seconds.  She tested in normal (warm) muscles.

She also tested our performance after putting our hands in ice water for 15 seconds.

And then we did it with our really warmed up muscles.  We all tested it, and 4 of her friends.


She recorded the number of grips we each did in the same amount of time.  She then made a graph to show the results.


  • Conclusions:
  1. Right hands are better.
  2. Hot muscles are better.
  3. Older is better than younger (people.)


And made the poster as well to share all of this information at the fair.

Learned few things and had fun.  Perfect!
