The document describes an experiment to investigate the relationship between height and jumping distance in 15 9-10 year old students. It was hypothesized that height would be greater than jumping distance. Each student's height and maximum jumping distance were measured and recorded. The results showed that in all cases height exceeded jumping distance, on average by 34.4 cm. It was concluded that for 9-10 year olds, height is always greater than jumping distance. Limitations around sample size and measurement accuracy are discussed.

1. What is the relationship between your jumping distance and your height?
Aim:
To investigate the relationship between a person’s height and jumping distance.
Hypothesis:
I predict that student’s height will be greater than their jumping distance.
Materials:
1 measuring tape
1 masking tape
1 sheet of a paper
1 pencil
1 clipboard
15 BISS grade4 student
1 ruler
Method:
1.Collect your materials.
2.Draw a table with 4 columns (name, height, jumping distance, difference)
3.Stick masking tape on the wall.
4.Ask someone to stick his/her back on the wall.
5. Draw a line on the tape to show the height.
6.Write the person’s name under the line.
7.Measure the distance from thefloor to the line.
8.Repeat this with the other 14 students.
9.Stick masking tape on the floor one short and vertical line and another long
and horizontal line.
10.Ask someone to jump from the vertical tape.
11.Draw a line on the horizontal tape where he/she jumps to.
12.Write the person’s name under the line.
13.Measure the distance from the vertical tape to the line on the horizontal tape.
14.Repeat this with other 14 students.
15.Write the results in the table.
Result:

Every person’s height is greater than their jumping distance.
In average person’s height is 34.40 cm greater than their jumping distance.
Conclusion:
Our hypothesis was correct. We conclude that at 9-10 years of age, every height
is greater than their jumping distance.
Discussion:
Our sample size was only fifteen 9-10 years olds. They came from variety of
backgrounds. We would need to measure more 9-10 year olds to be sure of
the percentage of student’s height and jumping distances in the world. This
would make our data more reliable.
We had some difficulties getting accurate measurements. When it was
jumping distance some people stepped over the line and jumped so it would
make the result 1 or 2cm more longer and some people didn’t do their best
jump. When we measured height their shoes made their height 1 or 2cm more
higher. This could make our measurements less accurate.
We would be interested in knowing how people’s height and jumping distance
change at different ages. It would be interesting to repeat this investigation on
babies, young children, teenagers and adults. This would help us to
understand the percentage of people’s height and jumping distances in the
world.
