1. Length Investigation
Aim:
To investigate the relationships between a person’s height and how far they can jump.
Hypothesis:
I predict that light and taller people jump further.
Materials:
Measuring paper
Scrap paper
Pencils, erasers
Clipboard
20 people
Ruler
Method:
1.Measure people’s height.
2.List it on the scrap paper.
3.Let people jump.
4.Measure how far people jump.
5.List it on the scrap paper.
6.Repeat it for 19 other people.
Results:

Conclusion:
My hypothesis was correct. Taller people jumped farther. I can see a linear relationship
between height and length on my graph. It’s not always true because some shorter people
jumped a long distance and some taller people jumped a short distance. Sometimes,
jumping length depends on other thing like strength.
Discussion:
My measurements might not be exactly accurate because some short people can jump
very far. Next time, I would like to investigate about how does blizzard happen, as a
science experiment, rather than a math investigation. It would also interesting to know if
these results change with age. We should repeat this investigation with children, older
sister/older brother, little sister/little brother, or mom/dad to find out.
