## Take a moment to answer these questions.

• How can you measure how fast you're walking?
• How can you measure or calculate the energy of an object in motion?
• Which type of energy is that?

## Build a pedometer!

We’ll use it to measure your steps and detect how fast you’re walking.

• Done! I’ve built my pedometer.

• I've programmed my pedometer.
• I've walked 10 steps to test my program.
• I've imported the data into my graph.
• How can you identify the individual steps in your graph data?

• I've found the threshold value to detect each peak on the graph.
• I’ve put in the threshold value in the variable.

## Convert your steps into a unit of speed, and then kinetic energy.

• I've converted my steps into speed (distance/time).
• I've walked slowly and then faster to see the change in speed.
• I've converted my steps into kinetic energy (½mv2).

## Spend more time exploring.

• I've found a cool way to display energy levels!

## How did you do?

How would you summarise your experiment?

Brilliant!
