We suggest students work in pairs. Homeschool students can work on their own.
To complete this lesson, students will need the ramps and levers they built in the previous lesson.
Students can also add a variety of materials to extend their chain-reaction machines. You can ask them to bring things in, or gather some basic materials to keep in the classroom. See the list below for items we recommend having on hand. Or, for more ideas, watch "Inspiration for Chain Reaction Builders" in Extensions before you start this activity to see some possibilities.
Each Chain Reaction Machine will take up several feet. Each student or group of students will need a table or several desks pushed together as a work space.
Marbles are very fun, but can be very distracting! We suggest waiting to distribute marbles to students until Step 14 of the activity.
