Launching 

When we were launching rocket 2 we had jobs like when we did our 1st launch. I was the rocket pumper so basically I got to pump air into the box with a bike pump. Every teem filled it to the same amount, 50 psi. It was mostly fun and a little bit hard. It was hard because it felt like there was a lot of resistance.  

 

Graphing 

After the launch all the teems had to graph the height of the rockets based on what the clonamoter readers said it was. The clononomer readers saw how high it went in clononomers, but we transferred it into feet. Our rocket went 139 feet which was a little disappointing because our first one went higher (the first one went 156 feet).

Designing

When we designed our 3rd rocket we changed the fins but left the nose cone and the body the same. We changed the fins this time because for our second rocket we could only change one thing and we changed the body from the thin tube to the thicker tube, but we also wanted to make the fins bigger, so now we can have both on one rocket. We decided to keep the body size and the nose cone size the same because we think that did better.

 

Building 

When we built our rocket we tried to make it the same exact thing as the design so that it would be accurate to what we wanted. I feel like this time there weren’t as many mistakes, I think that is because we had a lot of experience since we did it a lot. we also made the nose cone hot glued and taped.

Intro

Designing and building our first rocket was really fun because we got to be like engineers and design our rocket to be successful when we launch the rocket. It was also really fun because we where challenged to do our best when designing and building our Rocket, or else our Rocket would not go as high.

The Research  

Researching wasn’t that hard because I found a really good website called nasa.gov. It had so much good information about rockets and what they need, like: rockets need to be aerodynamic, they need to have a sharp nose cone and the wings need to be the same size and weight.

The Design 

Designing our first rocket was really fun since we got to do it on a google drawing. The actual design was it had three fins a pointy nose cone and we got to pick a body size, there was a small tube and a big tube. We chose the small tube because we thought that it would force the rocket up more.

Cooperation 

Our team was mostly really good at cooperating with each other. The only time we were not so good at cooperating was when we would make two things, but we only needed one thing and we would argue which one was better.

Building Our Rocket

when we built our rocket we made it really close to the design as possible. When we built it we used hot glue for putting the fins on and th nose cone on and we used tape over that to make sure it was completely on. We also put tin foil on the nose cone and on the fins because we thought that it would be smoother.

Designing Rocket #2

When we designed our second rocket we could only change one thing, we changed the tube from the smaller tube, to the bigger tube we think that this will help the rocket go higher.  

Building Rocket #2

Building our second rocket was actually not that hard because we knew how to do it from when we built our first rocket. I think that this time we also did it faster because we had experiences from when we built our first rocket.

I liked the sand box because it was cool how it moved and how it flooded. I also liked how you can put your hand over it to make it rain.

I learned that the root from the grass holds the dirt in place so when water goes threw as runoff the water is cleaner then just dirt or leaves and dirt. I also learned that sometimes even if the lake or pond is bigger it can still be deeper.

I think that you should add an activity ware you get a fish from any of the lakes or the pond and put it in water so we can report on the fish. Like we should see haw it moves or we should look at its giles and how the giles work.

Our trains used magnets to repel so they would float above the tracks. There are magnets on the track and on the car.Once the car could float above the tracks we would give it a push and it would glide across the track. Our car had strip magnets on the track and the car.

 

My car didn’t work on friday. I had hoped it would work on our first try because no other class had gotten it on their first try. I also thought it would work because Mrs. Mangan said we were close. After we ran out of time I realised that the strip magnets were not lined up so it would afect the magnets from repelling instead it would stick to the sides of the track.

 

I liked working with Rachel because she understood what I was thinking and she didn’t argue with me so we got a lot done. I think we will get it on our second try because we know what we did wrong.
