Speed Challenge Get Ready!

Step 1: Gather your materials!

• Each team needs 2 timers, 1 person to do the activity, and 1 person to record.

Step 2: Go for it!

• Each team will need to perform the following tasks for each distance: hopping, walking backwards, walking (regular rate), speed walking, and scooting.

• Record the time it takes to perform each task.

NOTE: Speed walking is going as fast as you can without jogging or running!

Collect That Data!

• Record your data from the experiment in the chart, then use the information to calculate the speed for each task and distance.

• Round answers to the nearest hundredth if needed. Label your answers!

Think About It!

***You do NOT have to use the 8 steps!

1. Which task and distance resulted in the fastest speed?

Task = ____________ Distance = ____________ Speed = ____________

2. Which task and distance resulted in the slowest speed?

Task = ____________ Distance = ____________ Speed = ____________

3. How long would it take you to hop 30 meters based on your speed for the 5 meter trial? Show your work!

4. How far could you speed walk in 10 minutes (600 seconds) based on your speed for the 10 meter trial? Show your work!

5. How far could you travel walking backwards in 15 minutes (900 seconds) based on your results for the 5 meter trial? Show your work!

6. How long would it take you to walk (regular rate) 1 kilometer (or 1,000 m) based on your speed for the 10 meter trial? Show your work!

7. There are a lot of sources for error in this lab. Write a few sentences to explain what could cause groups to have different numbers (answers).

Think About It!

***You do NOT have to use the 8 steps!

1. Which task and distance resulted in the fastest speed?

Task = ____________ Distance = ___5 or 10 m___ Speed = ____________

2. Which task and distance resulted in the slowest speed?

Task = ____________ Distance = ___5 or 10 m____ Speed = ____________

3. How long would it take you to hop 30 meters based on your speed for the 5 meter trial? Show your work!

Speed for 5 meter hop = Time = D/S (seconds)

T = 30 m/ speed

T = ?

4. How far could you speed walk in 10 minutes (600 seconds) based on your speed for the 10 meter trial? Show your work!

Speed for 10 m speed walk = D = S x T (meters)

D = speed x 600 seconds

D = ?

5. How far could you travel walking backwards in 15 minutes (900 seconds) based on your results for the 5 meter trial? Show your work!

Speed for 5 m backwards = D = S x T (meters)

D = speed x 900 seconds

D = ?

6. How long would it take you to walk (regular rate) 1 kilometer (or 1,000 m) based on your speed for the 10 meter trial? Show your work!

Speed for 10 meter walk = Time = D/ S

T = 1000m/ speed

T = ?

7. Were your results accurate? Write a few sentences to explain why or why not.

Possible errors:

• Stopwatch problems

• Person changing speed while doing activity

• Falls, people in the way…

-----------------------

S =

T =

D =

S = D/T

T = D/S

D = S x T

Average Time = (Time 1 + Time 2)
