Marble Run

Before getting started, make sure to have your guardian’s permission, be respectful of nature, and remember safety first! 

Deadline: September 25th

Objective :  To create a track that a ball can travel from start to finish in exactly 15 seconds


  1. Use recyclable materials for your track such as paper towel rolls, cardboard boxes, cereal or snack boxes, paper plates or cups, etc.

  2. While marbles work great, you can try ping-pong balls, bouncy balls, golf balls, etc.

  3. Start the timer when you let go of the ball at the starting point and end the timer when it gets to the end point.

    • Grades 5 and above should create a way to stop/trap the marble at the end.


Project Submission:  

  1. Please submit a picture or video of your marble run using the dropbox below.
