We had a visit from Mad Scientist Rhys today.
Logan tried to catch a falling ruler and a rolling pingpong ball. We learnt that reaction times can be improved with practise.
We used different sized balls and an air blower to find out about aerodynamics.
Naiya had to run on the spot for 1 minute. She was exhausted! But this showed that our heart rate increases when we exercise. This is because oxygen is carried in the blood to the muscles, and when we use our muscles more they need more oxygen.
Finally we saw a pretend Olympic torch. An air pump was attached to a hose with a funnel on the end. Some special fuel, in the form of a powder, was put into the funnel. Rhys lit a blowtorch. He pointed it in the direction of the funnel. When the air pump was squeezed the powder flew up into the air and caught alight. It looked like loads of little sparkles!
