Describe the transference of energy when throwing a rock into a lake. Where does it start where does it end?
It starts in your arm/hand as potential energy as you wind up, then as you throw, the energy transfers to rock. When the rock hits the water the energy transfers into the air as sound and into the water as ripples.

Mr. Melendez is building a bonfire and he uses a flint and steel.(Think MINECRAFT) He notices that he sees energy in its three forms making the bonfire! How do we see the energy as light? Heat? Where do we hear sound?
Light: Sparks on the flint and steel/the fire
Heat: From the burning wood/Fire
Sound: The flint and steel colliding, crackling of the fire
