Cards 1-4
When sunlight hits the solar panels, it transformed into electricity used to run the calculator and light the screen.
Card 5: Describe the energy transformation on this card
The potential electric energy is stored up as charge when the person scuffs his/her feet. When close to the doorknob, the energy is released or transformed into electricity, light and sound.
Card 9: Describe the energy transformation on this card
The plant absorbs sunlight and uses the energy to chemically combine CO2 and water into chemical potential energy for food.
Card 13: Describe the energy transformation on this card
When plugged in, the electricity is transformed into the motion of the blades, some sound and thermal energy.
Card 2: Describe the energy transformation on this card
Electromagnetic energy from the Sun is transformed into thermal energy that warms the pool.
Card 6: Describe the energy transformation on this card
The singer’s voice is transformed from sound to an electric signal that records the voice data.
Card 10: Describe the energy transformation on this card
A light bulb transforms electrical energy into light, thermal energy and sometimes sound.
Card 14: Describe the energy transformation on this card
The thermal energy of the stove is transferred to the water, which results in steam.
Card 3: Describe the energy transformation on this card
When burned, the chemical potential energy of the wax and wick are transformed into light and thermal energy.
Card 7: Describe the energy transformation on this card
The chemical potential energy in the furnace oil is burned and transformed to thermal energy and some light and sound.
Card 11: Describe the energy transformation on this card
The elastic potential energy of the bow is transferred to the arrow and transformed into motion and sound, and a little thermal energy.
Card 15: Describe the energy transformation on this card
The elastic potential energy is transformed into the motion of the foam, and a little thermal energy, when released.
Card 4: Describe the energy transformation on this card
The chemical potential energy in the food is metabolized by the soccer player and transformed into mechanical motion of playing and thermal energy that keeps the body warm.
Card 8: Describe the energy transformation on this card
Water falling over the dam loses gravitational potential energy and gains kinetic energy, until at the bottom it has been transformed into kinetic and some sound energy.
Card 12: Describe the energy transformation on this card
The chemical potential energy of the gas is transformed into thermal energy coming out of the engine, the motion of the pistons, and the sound of combustion.
Card 16: Describe the energy transformation on this card
Inside the Sun, energy is released when hydrogen nuclei are fused and give off electromagnetic light and thermal energy.
