I do something like this with my 9th graders, using the PASCO probes. We
do both d-t and v-t graphs, but
keep the motions very simple:

1. Walk away slowly. Walk away fast. Graph both lines on the same graph.
Compare slopes.

2. Walk towards slowly. Walk towards fast. Graph both lines on the same
graph. Compare slopes.

3. Walk away slowly, stop, walk back fast.

Discuss slopes, +/- values for velocity.
I then give them some sample graphs and they have to describe the motions
shown.
