A few days ago my class started working on a new science project, we’re making Rube Goldberg machines. Our teacher showed us some videos of people doing Rube Goldberg machines so we would get an idea of what to do. A Rube Goldberg machine is basically a chain reaction that’s really complicated but it does a really simple task.
First we picked partners or groups. I’m doing mine with my friends Emma and Karine. Then we made a shared doc that we could write some of our ideas on. Next thought of what to do for our task, we came up with four ideas:
-flushing a toilet
-turning on a light
-typing a key on a computer
-pressing an easy button
We realized that typing a key on the computer would be the easiest thing to do. I think my group works really well together and we have so much fun.
Today we had our rocketry presentations. I was so nervous I had butterflies in my stomach. During our rocketry unit we built and launched three rockets with our groups. There were 4 people in each group. My group name was the Radical Rockets. during our unit we also had to make slideshow of the process. When we finished our whole slideshow we had to work on memorizing all of our lines. I’m really bad at memorizing so I had to read through my lines so much. Before the presentations I was so nervous and I was also nervous while presenting. When I looked at the parents I kept forgetting my lines but when I looked at my friends I remembered, I think I got nervous when I looked at the parents and that’s why I forgot my lines. I stuttered once but the rest was really good. When I was done I felt so relived and so happy that it was finished. I loved the rocketry unit but presenting in front of my parents just made me scared. I came so far, from not knowing how to build a rocket, to becoming an expert.
In my class we studied ecosystems, I decided to do Rain Forests. For our final project to show what we know we are doing PSAs. Have you ever herd of them? A PSA is short for a Public Service Announcement.
