Catapults in Room 9

 Kia ora whānau,

Two scientific capabilities we have examined this year are observing and using evidence. These were explored during a class catapult challenge. Here group had to design catapults during only popsicle sticks, rubber bands and a cup to shot a pompom as far as possible. The class showed great resilience in their observations as they altered their designs to create the most elastic force possible. Evidence was collected using a trundle wheel and most groups were able to fire their pompom well over 4 metres!

Well done Room 9 – you are thinking like scientists!

Here is Christopher's catapult that he made at home – well done Christopher! I love the face and it looks like to have really used the elastics well to create more power.
