Objective: To determine if tall people run faster than sort people.

Hypothesis: My hypothesis is that the short people will have the highest average time, but there will be more tall people in the Olympics. I predict this because there are two types of muscle strength, weak and strong. The majority of people have weak muscles. That means that a short person could run fast with weak muscles because their legs are lighter to move. A tall person cannot go fast if their muscles are weak because their legs are too heavy to lift fast enough. So, the majority of the short people will run faster. Though if a tall person had strong and fast muscles they would have every advantage on their side (long strides, strong and fast muscles). My hypothesis is that the shorter people will have a higher average time but the tall people will have the fastest people.

Materials:

-Stop watch

-Pencil

-Paper

-Resources

-Computer

-Books

Participants

-5 tall people

-5 short people

-Timers

Variables

Independent:

-The person's height

Dependent:

Which height group runs faster

Control:

-Age of group

-Sex of group

-Distance

-Number of runs

Procedure:

1.Race and time 5 short people on a 25m dash.

2.Repeat 5 times

3.Race and time 5 tall people on a 25m dash.

4.Repeat 5 times

5.Compare the results from each race.

6.Determine which group ran the fastest.

7.Research Olympians and learn what height groupis most common in sprints.

8.Compare my results from my experiment and my research.

9.Conclude which height group runs the fastest.
