In this activity, students explore how train wheels are designed for stability on straight or curved rail. Students make two different models of train wheels from paper cups, observe how they perform on their homemade rail and compare the behaviour of their designs. The activity includes a list of what is required, suggestions of what to do and notice, questions to ask, an explanation for the underlying science of what students observe and suggestions for other related activities.
