Activities
- What does the Law of Conservation of Energy state?
- A television uses electrical energy to function. Explain how this electrical energy is transferred and conserved when the television is turned on.
- Use the energy pyramid below to summarize how energy would be transferred from the sun to a dolphin.
- How is potential energy related to kinetic energy?
Answer Key/Rubric
- The Law of Conservation of Energy states that the total amount of energy within a system remains constant. The energy is can be transferred or changed into a different form, but more is not created, and it is not destroyed.
- Acceptable responses may include, but are not limited to:
- Television uses electrical energy to function.
- The television changes the electrical energy into different forms when it is turned on.
- Light
- Sound
- Heat
- The amount of energy in this closed system remains constant.
- Acceptable responses may include, but are not limited to:
- The sun helps the phytoplankton to grow and make its own food.
- The phytoplankton uses the sun’s energy to perform its bodily functions. Some of the energy is lost as heat energy.
- The remainder of the phytoplankton’s energy is given to the zooplankton when it eats the phytoplankton.
- The zooplankton uses most of the phytoplankton’s energy to fuel its bodily functions. Some of the energy is lost as heat energy.
- The remainder of the zooplankton’s energy is given to the small fish when it eats the zooplankton.
- The small fish uses most of the zooplankton’s energy to fuel its bodily functions. Some of the energy is lost as heat energy.
- The remainder of the small fish’s energy is given to a larger fish when it eats the small fish.
- The large fish uses most of the small fish’s energy to fuel its bodily functions. Some of the energy is lost as heat energy.
- The remainder of the large fish’s energy is given to a dolphin when it eats the large fish.
- Acceptable responses may include, but are not limited to:
- Potential energy is stored energy.
- Kinetic energy is the energy of movement.
- An object has potential energy if it is not moving.
- When the object begins to move, the potential energy is transformed into kinetic energy.
- The sum of potential and kinetic energy always remains the same.
- When the object’s motion begins to slow, the kinetic energy is transformed back into potential energy.
