Heartbeat

Matthew discovers what happens when we excersise.

Matthew decided to listen to his heart before an after excersise. Here’s what happened.

You will need:

  • A heart
  • An obstacle course
  • A big space to excersise in

Method:

  1. Set up your obstacle course.
  2. Feel your heart – is it beating quickly or slowly?
  3. Try out your obstacle course and excersise.
  4. After excersising, feel you rheart again. Is it slower or faster than before?

How does it work?

Your heart should be faster after excersise. This is because, when you excersise, your heart has to pump blood around your body faster.
