Help, a Pipe is Leaking!!!

Published on 03/23/2005

Activity Overview

In this activity, students will simulate a pipe leaking and collect data.
Students will then use the TI-73 calculator to determine how many gallons would leak at that rate for a 30-day month.

Before the Activity

This activity works best with groups of four.
Place one plastic cup, one graduated cylinder (mL), one safety pin, a bottle of water, a stopwatch, and a couple of paper towels at each group's station.
Students will also need the TI-73 calculator.
It is best if students get their calculator after collecting the data.

During the Activity

Be sure students reset the memory on the TI-73 calculators.
Access MEM by pressing 2nd 0. Then press 7 (reset)and 1 (All RAM). Now press 2 to reset.

After the Activity

Review student results:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
