Here is our video and our presentation. |

Evidence of Work: Our goal with this project was to get a vehicle to travel exactly five meters with a mass of 250 grams displayed as pennies. Our solution was making a wooden car with space inside like a box to hold the pennies and sling that off a ramp using rubber bands. First we decided to make a car and not a zip line, then we made the car our first build day. The second day we built the ramp for the car, and the third day we ran tests on the Vehicle to ensure it always went five meters.

Content:
a. Distance vs. time-they both are constants that increase. D/T it went 5m in about 5s
b. Velocity-the rate at which something moves in direction. D/T our velocity is not constant it starts really high due to the rubber band slingshot then it slows down eventually stopping at 5m highest velocity is 2.5m/s
c. Spring Potential Energy- the force the spring or rubber band is able to apply.
d. Gravitational Potential Energy- at greater heights this increases. on earth is 9.8m/s
e. Kinetic Energy-energy of motion highest was 2.34J
f .Thermal Energy (and how it relates to the conservation of energy) Total E-KE-PE+THE
g. Friction- molecules rubbing against one another preventing motion . No equation.
Reflection for Trebuchet and Hybrid Car Projects
In the trebuchet project I was really good with communicating my ideas and problem solving. If we couldn't find a part like rubber bands that would be a problem. So to solve it I would go get the item. Finally when designing our Trebuchet I shared the ideas I had or options we could all collaborate on and choose the best outcome for our catapult. I suggested we should use a larger base so when firing the momentum wouldn't knock it over. In the Hybrid Vehicle Project I feel I demonstrated a good job in collaboration and time management. In the beginning of the project we started with several ideas for a vehicle that would work. I believe I contributed many ideas towards my groups design. When we finally settled on a design we finished making the vehicle in one build day so we were very productive day and had lots of time to spare.
Something I hope to improve on for the Trebuchet project is time management, and planning. The first day we started building we had little research on how trebuchets worked and how to make an effective one. I didn't really know what i was doing and in the future I would rather have done more planning so i would know how to create a great catapult. I would also want to work on my time management because I barely had enough time to finish the proof of efficacy document so in the future I will space out my time instead of procrastinating. For the Hybrid Car Project i think I should work on planning and presenting because i had a difficult time with both of these. When presenting I should enunciate more clearly and not rush through the information missing big parts of it. I don't think i really struggled in planning but I would like to do more of it with projects. I will research the topic in further depth and make a blueprint to scale so I have a better understanding of how we should solve the task.
