Energy

3. A circuit with more than one path for electricity to flow. If one part stops working, the others still work.
4. A circuit where electricity flows through one path. If one part stops working, the whole circuit stops.
5. Energy made by moving electric charges. It powers lights, computers, and other devices.
6. A material that lets all light pass through so you can see clearly through it (like glass).
9. Energy that we can see. It travels in waves and allows us to see objects around us.
10. Energy of motion or movement. It is what makes things move or work, like a moving car or spinning fan.
12. A material that lets some light through but not all, so things look blurry (like wax paper).
13. When light bounces off a surface, like a mirror or shiny metal.

1. Energy that comes from heat. The faster particles move, the more thermal energy there is.
2. The flow of electric energy through a wire or circuit.
4. Energy that we can hear. It is made when something vibrates and moves through air, water, or other materials.
7. When light bends as it passes from one material to another, like when a straw looks bent in a glass of water.
8. A material that does not let any light through (like wood or metal).
11. A path that electricity follows. It needs to be a complete loop for the energy to flow.
