• yes

• no

Open Ended

Think

Where does the energy from the battery in your phone go?

Define: law of conservation of energy.

The law of conservation of energy states that energy cannot be created or destroyed, but it can change its form.

Multiple Select

What are the two main forms of energy?

• kinetic energy

• potential energy

• light

• sound

Discuss the types of energy at position 1, 2, and 3 in the given image.

hint: which position does the roller coaster have high gravitational potential energy, and which position does it have more kinetic energy?

Plants and the Body- Are energy transformations also a part of plant and body systems?

• Photosynthesis is the process by which green plants transform energy from sunlight to produce their own food. 

• The energy stored in plants is the foundation for all energy transformations that occur in animals.

Multiple Choice
