Before even designing my car on tinkercad, I created a rough version of it with card to make sure the measurements I had originally written out would work in actuality.
Originally, I wanted the sides to be a trapezoid shape to make it more aesthetically appealing, however, I found that getting the measurements correct for this type of body would be difficult to do well, which would in turn make it less aesthetically appealing than a close-to-perfect rectangular body.
Once I had my new measurements, I was able to get started on tinkercad, which was definitely a more difficult part of the project because of the fact that I hadn’t used it in a while and was faced with a few issues that caused simple tasks to take longer than they should have.
For example, when I printed the car body, the holes I had designed to hold the axel were too low on the car body, and would not hold the axel.
I then found a material that had grooves running through it that were the perfect size for the axels I was using which i cut to match the size of the already printed car body. I then attached the wheels and moved on to the last little bit of the project which was the rubber band slingshot and the pole attached to the car.
I tried out a series of different types/sizes of rubber bands to see which would work best and ended up choosing a thinner, longer band. I then used a hot glue gun to glue a popsicle flat onto the front of the car and tested it out a few times. Here are some test runs:
- Risk Taker
- Postive and Energetic
- Aware and in control
- Active Listener
- Cooperative and Collaborative
- Leaders and Followers
- Positively Critical and Able to Act on Criticism
I think that being both a leader and a follower is very important while working in an ensemble since flexibility and compatibility is very useful in having an efficient and quality piece when working as a group. Personally I’m going to focus on being a risk taker this semester and gaining the courage to do more unexpected things in a scene, workshop, or while improvising.

What is this engineering task?
This engineering task is to create a device that can demonstrate basic energy transfer in an efficient and aesthetically pleasing way.
What are you thinking about doing?
I am looking to create a toy that can be used in a kindergarten classroom to introduce basic energy transfer and use. Possibly a car track like this one the is an example of potential energy being transformed.
This would be relatively easy to make/build meaning it is time efficient, while also being a good way to introduce basic energy transfer to both young children and older audiences.
