1 Energy Transformations

2 Energy Song! https://youtu.be/_uLSFigtLKg?list=PLSX I4GJ8v-oKFM_Sz6c5pXv1cMx0j-48t

3 Energy Transformations Chemical Mechanical Electrical Thermal (heat)

4 1. Chemical Energy Specific arrangement of chemicals

5 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.

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

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

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

9 3. Electrical Energy Energy of moving electrons

10 Examples of electrical energy Curling iron Toaster DVD player Refrigerator

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

12 Thermal (heat) Energy Conduction Convection Radiation

13 Conduction Transfer of energy through direct contact

14 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

15 Convection Movement that transfers heat in a liquid or gas

16 Examples of convection Heating your house Cooking soup Lava lamp

17 Radiation Transfer of energy by light

18 Examples of radiation Sunbathing Heat from a bonfire Tanning booth
