Energy Transfer and Transformation engages Grade 4 students with the idea that whenever there is a change, there is at least one form of energy causing that change. Students investigate evidence of energy all around them—when they flip on a light switch, feel a car start to move, or hear a phone ring. The relationship between energy and change becomes clearer when students understand that energy is observed in different forms, such as sound, light, thermal energy (heat), and electrical energy.
