Grade 9 Science Engineering Product — Develop and Plan

After deciding to build a boomerang can, the simple design and manufacturing process allowed me to draw a detailed model of the can and what happens when the machine is in motion.

Product Model:

The initial model shows the can when it is not moving, and we can see that there are only 4 simple materials needed to make the product. These are:

  • 1 Pringles Can
  • 1 Rubber band
  • 1 piece of masking tape
  • 4-5 coins

When the can is rolled across a flat surface, the initial kinetic energy created from the rolling action is converted into elastic strain energy as the rubber band is twisted due to the weight of the coins, as shown in the model below:

Since the project started last Wednesday (Feb 15), to finish the project in the time I created a schedule to plan the materials.

2.15: Start Define and Inquire blog post

2.17: N/A (Absent due to Beijing Arts Festival)

2.21: Start and complete Develop and Plan blog post

2.23: Bring all materials, start making product

2.27: Finish project, complete Create and Improve and Reflect and Share blog posts

I am very excited to build and have a lot of fun in this project! 🤭
