Energy Transformations • Chemical • Mechanical • Electrical • Thermal (heat)

1. Chemical Energy • Specific arrangement of chemicals

Examples of chemical energy • If you strike the wood end of a match, nothing happens. If you strike the tip with the chemicals, the match will light.

Examples of chemical energy • Hand warmers • Glow sticks • Injury packs • Batteries • Food

2. Mechanical Energy • Energy of an object that is moving

Examples of mechanical energy • Gears • Windmills • Riding a bike • Juggling • Turbines

3. Electrical Energy • Energy of moving electrons

Examples of electrical energy • Curling iron • Toaster • DVD player • Refrigerator

4. Thermal (heat) Energy • Movement of molecules to create heat

Thermal (heat) Energy • Conduction • Convection • Radiation

Conduction • Transfer of energy through direct contact

Examples of conduction • Burning your hand on the hot stove • Pancake on the griddle • Burning your feet on the pavement on a hot summer day

Convection • Movement that transfers heat in a liquid or gas

Examples of convection • Heating your house • Cooking soup • Lava lamp
