For my first project in the stem curriculum, me and my group created a Rube Goldberg machine. We had to incorporate at least five different steps across ten different steps, write a project history, make calculations or each step, and then present it on the first of october to three different judges.
My reflection
Me and my group worked really well together (at least for a group of all girls, save for me). We got to work almost immediately, with little to no arguments over how our device would be designed or how we would go about building, in fact the planning stage and the beginning of the build stage was really enjoyable. Then things got a bit frustrating, and partly due to me. I kept sneaking away to go and chat with my friend Conrad and I left my group shorthanded, which made the last couple of days before the presentation really stressful and packed. I was also tasked with working on calculations for the machine. I did the calculations just fine, until my group found out that we had a large amount of calculations that we didn't even know we could do (and on the last day too). My team spent the last day freaking out and working as hard as possible on the calculations, and we never got to how we were going to present our machine to the judges. We really dropped he ball on the presentation, and Ruby did most of the talking. I would definently stay with my group and not procrastinate as much.
Concepts
Force: Force is pretty self explanatory, it is the push or pull that results from one objects interaction with another.
Work: Work is when a force is applied to an object in order to move it, if the object moves, work has been done on it.
Potential Energy: Potential energy is the energy an object has due to its position.
Kinetic Energy: The energy an object has due to its motion.
Mechanical Advantage: The amount an input force is multiplied by due to a simple machine.
