Bell Ringer
Draw a distance-time graph of
the following scenario:
Martin gets in his car and speeds up to 60
mph. He then gets on the highway and
maintains a constant speed until he reaches his
exit. As he exits the highway, he slows down
and stops at the red light.

 Follow
my directions on how to make the pamphlet
 Make
up a graph (Distance-Time OR Velocity-Time) with you
group and draw it on the cover.
 Maximum of six changes in motion!
 When
I signal that time is up, pass your pamphlet to the next
group
 Example: Group 5

Practice #7
Draw a distance-time graph and velocity-time
graph of the following scenario:
Jeremy
is standing outside. He begins to run
and reaches a speed of 10 mph. He keeps
running at this speed for 1 hour and slows
down to 5 mph. After another hour, he stops to
catch his breath.

Practice #8
Draw a distance-time graph and velocity-time
graph of the following scenario:
Kiara
steps out of her car and speeds up to a fast
walking pace. She maintains this speed as she
walks down the road. As she approaches a
crosswalk, she slows down to a stop and waits for
the light. Kira realizes that at this pace she will be
late. She begins to run down the street and soon
reaches her office building.
