Energy changes are really important when we talk about how things change in the world around us, both physically and chemically.
In Physical Changes: Energy can either be taken in or given off. For instance, when ice melts, it takes in heat (which is energy) from the air around it. This heat helps the ice turn from a solid into a liquid.
In Chemical Changes: Energy changes show us that new substances are being made. During these reactions, energy can be released, like when something gets hotter or gives off light. On the other hand, some reactions, like photosynthesis in plants, take in energy from sunlight.
In short, understanding how energy moves helps us see how things change!
