    Section 3: Practical/Skills Section (30 marks)

    Julie and Richard decided to do a Science experiment to

    find out what conditions would cause the highest Heart

    rate. They set up the following experiment:

    Method:

    1. Get three people to laydown for five minutes, use

    a heart rate monitor to take

    their heart rates.

    2. Measure out and mark a100 m track.

    3. Tell them to walk 100m andtake their heart rates at the

    end of the walk.

    4. Rest for five minutes5. Repeat steps 3 and 4 for the jogging and

    sprinting conditions.

    Julie and Richard hypothesized that the sprinting conditionwould show the highest Heart rates.
