{Colossal Coasters}

To begin our unit on forces, we first had to learn about pushes and pulls.

We then conducted some experiments to learn how we can change the speed of moving objects.

We learned that if you adjust the incline or change the amount of friction on a path, you can slow down or speed up moving objects!

Throughout this week, we also completed a unit study on roller coasters.

We began by collecting some data:

We also accessed our roller coaster schema and then conducted research to learn more!

We completed a roller coaster writing this week as well:

 

We ended our unit by putting these discoveries to a true test!
The students built roller coasters!!!

We had 7 roller coasters constructed in our classroom and each group was able to create a working loop!

Here is a video of our work:
