Today we made some paper planes of our own design. My plane had a lot of force but not enough mass. I needed to fold the front so it would stray in the air longer. The thrust was really good but the drag dragged it down to quickly. Then we went ahead and designed our rocket and we originally went with 15m but we ran out of tape so we went with 13m. My rocket has an awesome design and I am have now got an aerodynamic, weight and drag proof, lift able design for my rocket. Havilla, Reid, Bethany and I worked together to measure the length of 13m.

P.s it was really fun!

Today we are learning about Newton third law of motion which is thrust. Then we are going to start designing. After that we will launch the rockets! Right now we just finished a mini test remembering Newtons first and Second law and answering questions. Then we went and launched our rockets. We went and filled our bottles 250ml of water then stuck on the nose cone and went outside. We set up the pump and then we launched. My my one went about 15m up then it came down. After that the pump was going a bit funny. When Reid pulled the trigger it didn't go up. Ms Chowlfin went and put her face to examine the bottler then it sprayed up she got drenched and it just skimmed her nose! It was really funny but also really dangerous. So next time just maybe safer. By the way when my rocket came down it hit the concrete and my wings came off. But i glue them back on anyway.

We quickly just went through the systems and what we are going to be doing today. We are going to launch our rockets, measure the angle, and the angle will be 45 angle. I am going to be recording my rocket. Such as air pressure, water level, and the time in the air. We will be test flying it at least once.

We just launched and it was epic! My rocket didn't go because it was broken so I worked with Caitlin. It went 23m and it stayed in the air for 3.88s which was good. The furthest rocket was 65m which was Ashas. Caitlin and I ran back and forth with the nozzle. It was an angle 45 and the water was 250ml.

Today we are doing the three laws of motion and how they apply to rockets. Then we are launching the rockets! His first law was Inertia, each force has a even bigger force, then each action has a reaction. Now we are going to weigh the rockets. The force pushes the rocket up, drag pulls it down, then the weight pulls down as well. We need to know this because we are going to weigh the rockets. I have weighed my rocket it weighs 400g. My rocket flew 18m and stayed in the air for 1.72s. It was really fun.
