4. In an outdoor plant, the process of photosynthesis converts carbon dioxide and water to glucose and oxygen. How is energy conserved within this system during this process?
a)
Thermal energy from the Sun transforms into light energy that is given off by the plant.
b)
Light is transformed into chemical and heat energy as the plant gets warmer in the sunlight.

6. What is the most accurate description of the energy conservation and transformations that are taking place in the roller coaster below?
a)
The roller coaster never has any potential energy because it is always moving.
b)
Potential energy is converted to kinetic energy and back again throughout the ride.
c)
The amount of potential energy is always equal to the amount of kinetic energy throughout the ride.
d)
The roller coaster has more total energy at the bottom of the track because more kinetic energy has been created.

9. Gabrielle built a simple circuit in science class. She knows that energy transforms within this system. Which of the following statements best describes the energy conservation and transformation in this electric circuit?
a)
Chemical energy in the batteries is transformed into light and heat energy but does not leave the system.
b)
Chemical energy leaves the batteries and transforms into light and heat energy, and then it is released from the system.
c)
Electrical energy travels from the light bulb to the batteries, where it is stored within the system.
d)
Heat and light energy leave the system but are replaced when the batteries are changed.
