1. Length Investigation
Aim:
To investigate the relationship between a person’s height
and how far they can jump.
Hypothesis:
We predict that taller people jump further than shorter
people.
Materials:
Measuring tape
Pencil
Clipboard
20 people
Paper
Sticky tape
Method:
1. In this experiment, you need some partners.
2. Aska partner to help.
3. Measure a person’s height, using a measuring tape.
4. Check if there are any mistakes, such as measuring tape
or person’s legs not being straight.
5. Record a person’s height on the paper.
6. Now ask people to do standing jumps.
7. Warning: try to tell person not to jump on the smooth
ground because he/she might slip off.
8. Tell a person to jump.
9. Now measure a person’s jump.
10.Use sticky tape if you want. (Ithelps you to indicate the
length.)
11.Record person’s jump record.
12.Check that the measurement is correct.
13.Record your measurements in a table.

Conclusion:
My hypothesis was correct. Taller people jump further in
most cases. I can see a mostly linear relationship on my
graph.
Also, people can jump further than their height. On average,
people jumped 22cm longer than their height.
Discussion:
Our sample size was only 20 people. We would need to
measure the lengths of height more successfully. Most of us
had some problems getting the average because there were
loads of height and jump numbers to add and it was really
confusing. Beside, there were also some difficulties
organizing the table. Also it was hard to compare numbers. I
was tremendously interested inmaking a table because
actually there are no single answers but I just enjoyed
learning the new skill.
Next time if I do this experiment again I would try to make it
better than what I did and also I will try to make it more
successful by measuring more accurately.
