Create and Improve

Day 1:

I did not have evidence of my project on this day because I did not bring my phone today. Today was the first day in the design studio so we worked on finding materials and double checking with the teachers about our designs. I made some changes to my design because the wood was too heavy I was scared a bottle cap couldn’t support it I wanted to change the materials of the wheels to an actual toy wheel they had in the supply section. I did not gather much feedback and improvements today except for changing thee material of the wood.

Day 2:

After gathering all my materials I started to cut a few pieces of wood. I learned how to use the electric saw from the teacher in the design studio. After cutting the four pieces of wood, I glued the body of the car together. Then I took my materials for the wheels and sticked the straw on the bottom of the car. I made a mistake at first and stuck the straw also on the wheels but that means the car wasn’t able to spin and the car wouldn’t work. I took the wheels apart and put a metal stick through the straw and put the wheels on the two sides. This way, the wheels on the side are able to move but it is still attached to the car itself.

Day 3 (test day):

I put together the launcher today and put the elastic band on the two sides of the launcher. I tested it at first and the elastic wasn’t long enough so I had to put two elastic bands together. I improved the launcher by making the elastic band looser so that the car and move more to the back and the car can be launched even further. I also tried to put other weights on the car (I forgot to record it down) but it worked and was able to carry the things from the launcher to the open space. This car is able to transfer potential energy from me pulling the elastic band back and the elastic energy moves the car forwards into kinetic energy.

Day 4:

I finished the original car I was making last time and I had two more classes left in the design center. I decided to make the other design that I had planned. I gathered my materials and stuck wooden sticks together with hot glue. I used straws and wooden sticks along with two gears as the wheels. I couldn’t finish the car today but I plan on using an elastic band to tie around the stick in the middle of the second stick to the tip of the car. I’m not sure if the wheels can support the car and i will test the car next class.

Day 5 (test day):

Today is the last day in the design center and I finished most of my product. I did not get to put a piece of wood over the car so that it can place objects over. I changed the back wheels of the car into a small toy car wheel because when I used the same sizes gear the car did not move at all. Then I tried to change the gear to a bigger gear but the car only moved a little bit because the car was too light to move forwards. So I changed the back wheels to the toy car wheel and the car gained more weight so it moved forwards and has a lot of speed. This car is able to transfer potential energy from me pulling the car back and the elastic band spins back and the elastic energy moves the car forwards into kinetic energy.
