Energy | Centers
Students explore how energy is stored, transferred, and used in robotics through hands-on center activities. They analyze how different energy sources and efficiency choices affect robot performance, then apply their learning to simple design decisions.
| Term | Definition |
|---|---|
| Energy | The ability to do work or cause change. |
| Electrical energy | Energy carried by electric current in a circuit. |
| Kinetic energy | Energy of motion. |
| Potential energy | Stored energy that can be used later. |
| Efficiency | How much useful output is produced compared to the energy used. |
| Transfer | Movement of energy from one object or form to another. |
| Transformation | A change from one form of energy to another. |
Show a robot or robot image and ask: Where does its energy come from, and what does it become? Briefly introduce the idea that robots need energy to sense, think, and move.
Think-pair-share ideas and record one source of energy and one way the robot uses it.
Set up cards or real examples of batteries, charging systems, solar, and plug-in power. Ask students to sort by likely use and discuss advantages and limits.
Sort energy sources and justify their choices using vocabulary terms.
Guide students in building a simple motor circuit or testing an existing robot motion system. Prompt them to observe what happens when power is increased, reduced, or interrupted.
Build or test the circuit, observe motor behavior, and record how electrical energy becomes motion.
Give students a simple task such as moving a small object using a robot car or model. Ask them to test one variable at a time, such as wheel type, load, or surface.
Run trials, compare results, and note which design changes improve or reduce energy use.
Provide a short article, infographic, or video about energy storage in robots and rechargeable batteries. Ask focused questions about tradeoffs.
Read, watch, and answer questions about how robots store and use energy.
Prompt students to sketch a robot design and label where energy is stored, transferred, and used. Encourage clear reasoning about efficiency.
Create a labeled sketch and explain one design choice that supports better energy use.
Facilitate a brief discussion connecting center discoveries to the big idea that robot performance depends on smart energy choices.
Share one finding from a center and one new idea about energy in robotics.
Ask students to write one sentence answering: What energy choice would make a robot work better and why?
Submit a short written response.
Reinforce that robots depend on energy sources, circuits, and efficient design to perform well. Connect student observations to real-world robotics where battery life, weight, and power management matter.
At home, find one robot or device that uses energy and write 5 to 7 sentences explaining its energy source, how the energy is used, and one way the design could be more efficient.
