Average SpeedChuck Faber, Christopher Adame, Krissy Hopper, and Bridget Gengler

Eight grade standard 1 c. Students know now to solve

problems involving time, distance and average speed.

Vocab Review

Do-NOW!In your notebook answer these questions…..How far did you walk

from the doorway to your seat?

How long did it take you to walk the distance?

What do you think your average speed was?

Distance: measurement of how far apart objects are.

Time: measurement of duration

How long?

Average speed: total distance per unit of time.

s=d/t

Class Demo?• Pick a volunteer from

the class to walk from their desk to the door.

• Have class makes predictions on how fast he/she will travel (average speed).

• Measure and time the walk.

• As a class determine the average speed.

Group work!• Have students get into their lab groups (about 4

students).• Students work on a computer simulation of a runner on

average speed.• Each group must complete one worksheet.• Review theirs answers as a class.

FormulasClassworkPass out time, distance

and speed worksheets.Work in pairs.Teacher should model

how to approach these problems. What is given? What do you need?

What is not finished is HW!

S= d/t

How can you find distance?D=s*t

How can you solve for time?T=d/s

Average Speed Lab Pass out worksheets at

end of class explaining lab. Have each group assign a

measurer, timer, roller, and catcher.

Explain each job and their duties.

Have students prep their science notebooks for the lab. Write title, etc.
