Heat and Light

In science we are learning about two forms of energy, heat and light.  Heat describes the amount of thermal energy an object has.  Light allows us to see things, and travels through space and air in waves.

Remember that thermal energy can affect objects in many different ways.  Some objects can expand or move.  Or it can change the state of an object, from solid to liquid, or even from liquid to gas.  For example, think of an ice cube melting in a warm glass of water.  Thermal energy is transferred to the ice cube and the ice melts.

Here is a video to introduce heat energy to us.
