I purchased a Pop Up A Rocket online and it arrived in the last week of the school term. We took it out on the oval to test it out so that we wouldn’t lose the rockets on the roof. We lined up behind the pump section to take turns. We soon learnt that if you jumped on the pump really quickly and really hard it made the rocket jettison high into the air. After we set the rocket off each child went running off to collect their rocket while I set up the next rocket for the next child. The system worked well and the children soon got the hang of it.
Later in the week we decided to make our own air powered rockets. We started off by drawing tiny rockets. We had pre-cut the paper to a small size to ensure that the children made the rockets the right size. The children then cut out their rockets and we stuck them halfway up a matchstick with masking tape. We left half of the matchstick hanging out of the end of the rocket so we could stick this in the end of the straw.
We also stuck a masking tape tag on each straw to make sure that each child only used their own straw. Then we placed the matchstick into the end of the straw. We bent the bendy bit of the straw and blew in the short end to blow our rockets into the air. The harder we blew the higher our rockets soared.
