On Your Mark, Get Set, Roll
Grades 4-12 120 min (Two 60-minute sessions) Engineering Physical Science
On Your Mark, Get Set, Roll

Students will explore how to create triggers by building a device that releases a ball when activated. Their design will need to include a trigger that can be activated from three or more feet away from the device.
Resources
Objectives:
- Consider how to use potential energy to build a trigger (release mechanism).
- Design a ball-release device that is activated by a trigger.
- Iterate on the design by building a different method for activating the device.

The Tech Challenge
This resource was developed to prepare students for the 2024 Tech Challenge. Each year The Tech Challenge invites teams of students in Grades 4-12 to use the engineering design process to solve a real-world problem.
