Investigating forces, energy, and Earth's place in the universe.
Energy cannot be created or destroyed, only changed from one form to another. This is called the Law of Conservation of Energy.
Knowing how energy transforms helps us use energy wisely and invent machines that waste less. Engineers design cars, homes, and gadgets to be energy efficient, saving resources and money.
Even when you slide down a slide, some energy turns into heat because of friction!
A toaster turns electrical energy into heat to make toast.
Plants turn sunlight into food energy through photosynthesis.
Energy changes forms but is never lost; it’s always conserved.
