On Tuesday, February 26, my partner and I started building our Rube Goldberg. Our simple machines are the inclined plane, the lever, and the wheel and axle. We started with our beginning, which is a lot of paper towel rolls and toilet paper rolls taped together, to make the marble roll down the stairs. My partner and I decided to put a chair in the back of the tube, so the tube would be higher, and the marble will have more power. We tried to tape the tube onto the chair but it wouldn’t stick. Then, we tried to tie the tube to the chair, and it worked. Then, we started building the rest. The ball was supposed to knock down a tall box. We dropped the ball in the tube and the ball went into a different direction. We tried again, but the ball still went in a different direction, and not straight into the box. We haven’t found a way to fix this yet, but we are really excited to see the whole Rube Goldberg built.

Rube Goldberg #3
After my partner and I finished the sketch, we realized that we only had one simple machine, which was the inclined plane. We had to start with a brand new piece of paper and started the sketch again. First, we thought of making a pulley. We thought of making it with a tape roll and string. We realized that there would be nowhere to hang the pulley, so we thought of a different simple machine. While it was Winter Break, I thought of trying to make a lever and a wheel and axle. After Winter Break, we tried looking for materials to make the lever and the wheel and axle. For our wheel and axle, we used a toy car, and for our lever, we used a tinfoil roll and a plastic lid.
Volleyball Game
On Friday, February 15, is the Volleyball Game. Each class gets a color to wear, and each class plays against the teachers. I am so excited for the Volleyball Game!
Recycling
On Thursday, February 14, Monica came into teach us about how recycling works. First, Monica told us to draw things that are made out of one material, draw things that can’t be disassemble easily, and draw things that can change shape and why. Earlier, Monica gave us tin foil to build things out it. First, she told us to build something out of tin foil that you can wear. What I made was a shoe. Then, Monica said to get a partner and make gifts for each other. Before we made gifts for our partner, we had to make the tin foil flat again. I ripped mine a few times while I was trying to flatten my tin foil out. Since that happened, I only had a few scraps of tin foil left, so I made my partner a ring.
After we did that activity, Monica gave us a lid of a box filled with different types of bottle caps, nails, pins, and clothing pins. Like in recycling centers, we had to sort them out, but we had to make a tool that was made out of more than one material, that would help us sort them out. We got split up into two groups of eight. Two people are in charge of one material so me and my partner, Sabrina, were in charge of sorting the nails and pins. My partner and I made a tool that would scoop the nails and pins up. The tool was made out of tin foil, post-its, and a pencil.
On Thursday, I learned how people recycle plastic bottles. First, they separate the bottle caps and the plastic bottle itself. Then, the bottles get shred into pieces. Finally, they are melted into small pellets. They are shipped to companies that can melt them and make the plastic different products. Depending on how you recycle plastic bottles, it can be a pollutant.
How I can help is next time I buy a plastic bottle from a grocery store, I’ll reuse the bottle instead of throwing it out. I had a really fun experience and learned a lot about recycling.
Rube Goldberg #2
After my partner and I finished the sketch and the list of materials for our Rube Goldberg, we started collecting paper towel rolls and toilet paper rolls. My partner and I are going to tape the paper towel rolls and the toilet paper rolls because my partner and I want it to be tube-like. The tube will be held up by the books on the chair. The tube is very important because that is the beginning of the Rube Goldberg. The marble is going to go through the tube and start going further down the stairs to knock the bag of chips into the bowl.
Rube Goldberg #1
On February 5, my partner and I started working on our Rube Goldberg. My partner and I started sketching and wrote down the materials that we needed. Our goal is to put chips in a bowl. The materials we need is a chair, books, paper towel rolls, toilet paper rolls, binders, marbles, small box, bowl, chips, and tape/glue. My partner and I decided to use stairs as a platform for our Rube Goldberg instead of a flat surface because the marble might stop. My partner and I are very excited to start building.
