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.
