1. Length Investigation
Aim: to investigate the relationship between height and jumping distance
Hypothesis: I predict that height and jumping distance will be same.
Materials:
1 pencil
15 Grade4 students
1 roll of masking tape
1 clipboard
1 sheet of paper
1 ruler
Method:
1. Collect all your materials.
2. Stick some masking tape on the wall.
3. Ask the person to take off their shoes.
4. Put a ruler on top of the person’s head and mark the height.
5. Measure the person’s height.
6. Do the same for the other 14 students.
7. Place some masking tape on the floor.
8. Put some more tape perpendicular to the first tape.
9. Let the person jump.
10. Put the ruler at the back of the person’s feet and mark the place with a pencil.
11. Measure the distance jumped.
12. Do the same for the other 14 students.

Benedict 149 124 +25
All Grade 4students’ height was greater than their jumping distance. On average,
people’s height is 43.1 cm longer than their jumping distance.
Conclusion:
My hypothesis was wrong. People’s height was greater than their jumping distance.
Discussion:
How reliable are your results?
We only measured 15 Grade4 students. They came from different countries. To
make our information more reliable, we need to measure more Grade4 students.
What can you do next to investigate this topic?
I would be interested to do this investigation with babies, adults, teenagers, etc.
