We suggest students work in pairs. Homeschool students can work on their own, but they will need to make two models so that they can compare and contrast what happens when using the thin versus thick rubber band.
Student pairs will need to set up two Twist-O-Matic models next to each other for easier comparison between the thin and thick rubber bands. Each model takes up the space of about one student desk, so it is easiest if student pairs are sitting next to one another.
