Chemical Energy Chemical energy is the energy of rearranging atoms The atoms of a compound are rearranged to form new compounds Since work was done to join or bond the atoms together, when they are broken apart and rearranged energy is released Example: Burning wood Examine this link to see Energy in a Coal Power Plant https://www.youtube.com/watch?v=XZXySQ5xpt0

Chemical Energy Carbon Dioxide Water Sugar Oxygen Life is only possible on our planet because the sun provides us energy for photosynthesis Photosynthesis is a process where plants use light energy to produce new substances with chemical energy Sunlight Carbon Dioxide Water Sugar Oxygen

Chemical Energy You take in the plants sugar by EATING! Your body gets it’s energy by breaking the bonds in food and then performs energy conversions You convert chemical energy in the food to kinetic energy when you are active and convert it to thermal energy to maintain body temperature https://www.youtube.com/watch?v=y_omJiYB2gk

Why is the sun the ultimate energy source on our planet?

Photosynthesis Gizmo! Photosynthesis is the conversion of light energy into chemical energy as plants grow.
