Marble Rollercoaster

consider this

In this activity, you will create a rollercoaster ride for a marble or a small ball. Using paper, craft materials, recyclables, and other objects around you, create a rollercoaster ride! You can use gravity as your source of energy by starting at a high point, and ending at a low point. What could you make the marble do? Ramp? Even a loop de loop!?!

key terms

gravity: (noun) physical force by which objects attract, or pull toward, each other. the earth is very large and therefore has a strong gravitational pull, that's why when you drop an object it falls to the floor

motion: (noun) a change in position compared to a place or an object that is not moving

energy: (noun) capacity to do work

inclined plane: (noun) sloping surface used for raising heavy bodies. it is easier to push a heavy object up a slope than to lift it

How can you complete this task? What materials do you have that could help you make a rollercoaster track? How are you going to keep the “marble” on track? What else could you add to bring more creativity and originality?

design and build a prototype

What can you use to create a roller coaster? Can you create a ramp? Or even a loop de loop? What other materials can you use? What could you use as supports? What else could you add to make your roller coaster stand out from the other roller coasters? Tip – Fold the paper to create a channel/track for the marble to roll in. You can change this design to have your marble do many things.
