In this design challenge, you will create your own roller coaster, using a marble or small ball as your cart. This activity is a great introduction to hands-on engineering for children 6 and up, and it can be used to introduce connections of energy and friction for older children. While the activity can be completed in around 20 minutes, don’t be surprised if your family spends 45 to 60 minutes perfecting their creations, or building an entire amusement park in your living room!
Create a coaster that will deliver your ‘cart’ safely into a cup at the end of your track.
Bonus challenge: Make your coaster stand up on its own.
The roller coaster track can be built from all types of materials, depending on what you want it to do (note: use more flexible yet sturdy materials if you are going to include loops). Explore your junk drawer or recycling bin to find unique items.
