Light, Energy and Circuits

4. Energy Energy due to an object’s motion or position.
6. A substance through which energy travels (like air, water, glass).
7. Circuit, An incomplete circuit where current cannot flow.
8. Energy Heat energy due to the motion of particles in matter.
11. A safety device that stops the flow of current if it becomes too high.
12. A transparent object that bends light to focus or spread it.
14. of Energy The process of changing energy from one form to another.
17. Source, The origin of energy used to power a circuit (e.g., battery).
18. A material that conducts electricity well (e.g., metal).
19. A transparent object that separates light into its color spectrum.
20. Path A complete loop that allows electric current to flow.
21. A material that does not let light pass through.
23. To pass energy (like light or electricity) through a material.
24. Current, The flow of electric charge through a conductor.
27. Energy Energy produced by vibrating objects, transmitted through a medium.
28. To change energy from one form to another.
29. Circuit A path in which electrons flow from a power source through a loop and back.
30. Energy A form of energy that is visible and travels in waves.
31. Energy Energy stored in the bonds of chemical compounds.
32. A device used to open or close a circuit.

1. The bending of light as it passes from one medium to another.
2. of Energy The change of energy from one form to another.
3. Transfer Movement of energy from one object or system to another.
5. Energy Energy caused by the movement of electrons.
8. A material that allows light to pass through clearly.
9. The process of taking in light energy without reflecting it.
10. Goldberg A complex machine designed to perform a simple task in a convoluted way.
13. The bouncing back of light from a surface.
14. Circuit, A complete electrical connection that allows current to flow.
15. The movement of electric charge or energy.
16. A material that resists the flow of electric current.
22. Circuit, A system of electrical components connected to carry current.
25. Material A material that allows electric current to pass through easily.
26. A material that allows some light to pass through, but not clearly.
