In PS3: Energy, performance expectations are designed for students to create an understanding of energy, energy conservation and transfer, the relationship between energy and forces, and energy in everyday life. Some key concepts in energy for grades 3-5 understanding are the motion of energy, conservation of energy, and the relationship between magnets and energy.
4-PS3-1 Use evidence to construct an explanation relating the speed of an object to the energy of that object.
5-PS3-1 Use models to describe that energy in animals’ food (used for body repair, growth, motion, and to maintain body warmth) was once energy from the sun.
4-PS3-2 Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
4-PS3-3 Ask questions and predict outcomes about the changes in energy that occur when objects collide.
4-PS3-4 Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.
