7. Which wheels are the best? Case study – skateboards
Field: physical science
The example of skateboard wheels is good for this project. Hard friction and fast wear off of skateboard wheels can be a starting point of the research. By examining different types of skateboard wheels, you will see which are good for what – some are perhaps better for maneuvering but are more prone to wearing off for example? Well, in this project you will find that out and point out your results and your opinions, and you have to agree that this is one fun and easy award winning science fair project for 9th grade.
