The other day after I made the brainstorm my family and I went on a walk to a park and attempted to launch the baking soda and vinegar rocket. We brought all the materials to the park and set everything up. The rocket launched about half a metre into the air. We figured out why it didn't launch higher, it was because the cork wasn't long enough so it didn't build enough pressure for it to go higher. Next time I will get a longer cork.
Here is a video of the rocket launching:
In Blastoff we are learning about flight. We had to make a diagram of the four forces of flight. we had to label where the thrust, drag, lift and gravity is on an aeroplane. I put arrows to show where they are indicated.
In the past week in my Blast off class, we have been learning about rockets. For our project rocket, we have to make a model of a rocket that will actually fly, but there's a catch, we have to make the rocket so it can be built by year 3 students. We also have to teach the students a lesson on forces, we have to make it easy for them to understand, so no big words that they might not know.
Here is a brainstorm on an idea that could work:
This term my modules were Blast off and Amazing adaptations. In Blast off I have enjoyed working with my buddy and building catapults and rube goldberg machines. The rube gold berg machines were really hard to make because the dominos that we used were too small so we had to change them to jengas. In amazing adaptations we were writing reports on amazing animals. My report is about the fennec fox and I have finished it but I just need to add some things to make it sound really good. In literacy we are watching movies and doing little tasks that go with the movie, the movie that my group is watching is: Horton hears a who. In Numeracy we are doing algebra and simplifying equations, its a little bit hard and I needed help with simplifying algebra equations but otherwise I think i'm doing ok in numeracy. In Te Whare we are learning about saints that went on journeys like Moses, Abraham and Sarah, Saint Paul and Jesus.
This year the yr7s and yr8s are going on a ski trip. I am going to try and pack my own bag without my Mum helping me. I am really looking forward to skiing in the cold, icy snow.
In the past few weeks in blast off we have been making Rube goldberg machines. Rube goldberg machines are complex machines doing simple tasks, these tasks could be: putting a ball in a bucket, put a bottle in a bin, ring a bell, switch off a light or some other tasks. Our task was to get a ball in a cup, we used: jenga, tennis ball, glue stick, car, tracks, marble, roll of tape, domino lid and dominos. Together we made this machine:
This week in blast off we built catapults. We had to follow some instructions on how you build them. We made three models, One that is small, one with a triangle base and one with a square base. We had to indentify the energys that catapults hold, when it is launching it has elastic and potencial energy, when it is in the air it has kinetic energy.
Here are some slides on our recorded data and the instructions so you can build them too:
