Energy | Centers
Students rotate through simple centers to identify common energy sources used in robotics, observe how energy changes form, and connect energy use to robot performance in a practical, low-pressure way.
| Term | Definition |
|---|---|
| Energy | The ability to do work or cause change. |
| Electrical energy | Energy carried by electric current and used by most robots. |
| Battery | A device that stores chemical energy and provides electrical energy. |
| Power supply | A source that delivers electrical energy to a device. |
| Conversion | The process of changing energy from one form to another. |
| Runtime | How long a robot can operate before energy is depleted or needs recharging. |
Briefly review what energy is and how robots need energy to move, sense, and compute. Explain the center rotation routine, group roles, and expected cleanup.
Listen, ask clarifying questions, and form small groups.
Guide students to inspect batteries, battery packs, and a power supply diagram. Prompt them to note where the energy comes from and how it reaches the robot.
Compare energy sources and record one advantage and one limitation of each.
Ask students to test or observe a small motor and LED demonstration. Emphasize what form the input energy becomes.
Observe movement and light output, then identify the energy conversion shown.
Show how a multimeter or voltage tester can indicate electrical output. Keep the task simple and observational rather than technical.
Take basic readings or inspect sample values and note which setup appears to use more or less power.
Provide simple robot design cards or scenarios. Ask students to decide which energy source best fits a short task, a long task, or a mobile robot.
Choose the best option for each scenario and explain their reasoning in one sentence.
Invite each group to share one thing they learned about robot energy.
Share a quick observation with the class.
End with a quick verbal summary: robots need energy input, energy changes form, and the right source depends on the robot’s job. Confirm the key idea that energy choice affects performance, runtime, and design.
