This week in Challenge club we completed 2 STEM challenge cards. STEM stands for Science, Technology, Engineering and Maths.

The first challenge we took part in was trying to get 2 ping pong balls to float above a hairdryer that was on. We got 1 to float but found it difficult for the other one to stay in the air. This is because they kept on hitting each other and the air current could only work around one ping pong ball.

The second challenge we completed was to make a car safe if it had a crash. We designed a crumple zone for the front, back and sides of the car. We used paper, sellotape, masking tape and straws to make the crumble zone on our toy car. We tested our crumple zones by shooting a car towards a wooden block. Some of us were successful and the crumple zone survived, some did not!

We can’t wait for the next challenge club next week.
