Trebuchet reflective questions
1. For our time period we chose western Europe in the middle ages. Our trebuchet has a basic counter weight system which was present in the time period. The materials that they used in the middle ages were very simple such as metal and wood. Cormac and I did our best to represent the same materials in our trebuchet but I feel we could've done better. I feel our project is a good representation of a trebuchet in the middle ages
2. I feel that Cormac and I collaborated very well and we were able to get a very well functioning trebuchet. I feel that we could've focused more on the aesthetic side of the trebuchet. I feel we could've been more creative when we decorated the our project. Overall I was pleased with our end product

Rube Goldberg Reflection
Before the rube goldberg project we learned about simple machines and how we use them in everyday life. When we built the rube it was no exception. We used a simple machine in almost every step. In the second step we used an inclined plane to move a car. In the third step we used a pulley to transfer weight from one side to another. In the second step we used a toy car which had a wheel and axle. Before we learned about simple machines, we learned about physics principles. In the second step there was a car stuck on top of the hill, that car had potential energy. On the fourth step we used momentum of dominoes to create a continuous domino train. On the final step we used the speed of a tennis ball to trigger the final step.
Math and physics are very important and they are very closely related. All basic physics properties can be broken down into a math equation. To start your Rube you drop a 7.0 gram steel ball 50 centimeters into a pulley system. Calculate the potential energy for the step.
(0.007kg)x(9.8m/s2)x(0.5m)
PE=0.0343 Joules
When your steel ball lands in the tiny bucket it has a velocity of 45cm/s. Calculate the kinetic energy of the steel ball
.5x (0.007kg)x(45m/s2)x(.5)x.(20250)x(0.007kg)

The design process for our rube went really smooth. We just drew out an idea of our rube and tried to fit as much as we could into the actual rube. The only really problem we had was, how we were going to suspend our rube. We decided to make a wall so it would be easy to apply steps and add more room if needed. I believe our best 21st century skill that we used in our rube was creativity. During the building process of the rube we hit a lot of roadblocks, and to get over them we had to think creatively. Another way we used creativity was our satire. We wanted our rube to put off a powerful message that would motivate for change. We decided to go with the theme of how humans are ruining the planet. I feel the 21st century skill that I grew the most in was communication. I often struggle with group work but this time around I was able to communicate with my group members better than before. The rube project always kept me on my toes and I can’t wait to see what comes next.
