This week, we learned about the 5 simple machines. For our project, we made a catapult. Basically, we made a goal and took a video of us launching it and then answered some questions. For example, it asked “What’s your effort arm?” and “What’s your load arm?”. My load was 5 and my effort was 6, which made my mechanical advantage 1.2!
ROBLOX, roblox is a game that includes a lot of technology and coding. ROBLOX is a game for all children and there are games inside of roblox. There’s like “Welcome to Bloxburg”, “Adopt Me”, and “Royale High”. These games all involve coding like in Royale High, when you make diamonds, you need to code that it can show the diamonds on the side or something. Or when you buy an egg and hatch it, Or when you place a wall in Bloxburg.
This weeks project is making a truss bridge or something that can hold up weight. It’s all about the triangles. Tomorrow we will start the actual project and build it. The materials we are using are carrots/gummy bears/fruit snacks and toothpicks. We use the toothpicks to stab the food and make a sculpture and take a video and post it to Flipgrid. I can’t wait to try it and I think that ill be able to hold at least 4 books on my truss. Tech has been really fun so far and I think its better than Computer Tech already. He already told us that we are starting a new project on a camera/crank thing. We have to use the safety cutter and this year we are just practicing using it.
This weeks project is comparing two beams. One is an
I-beam and the other is our own custom design. What you do is you follow the video that he gave us and make the I-beam and then make your own beam, which I just made a square beam. Then you tested it by putting two chairs together and putting the beam on the chairs and it should have the ends on the chairs and the middle touching nothing. You then get cans of soup and put them in a bag and put the bag on the beam. You keep adding cans till the beams can’t hold anymore. For me, my own custom beam worked a lot better then the first one. The I-beam bent in the middle and it started cracking with 5 cans, so I removed one and I bet 4 would’ve done well but I didn’t test it because it already cracked. My beam held 6 cans, it might’ve been able to add another too.
