Which of the following does NOT correctly pair a source of chemical energy with the kinetic energy that it is transformed into? (DOK 2)
Food → animal running
Batteries → toy car moving
Spring → pop-up toy jumping
In the process of photosynthesis in an outdoor plant, like grass, sugar is made for food. How is energy conserved within this system during this process? (DOK 2)
Light is transformed into chemical and heat energy as the plant gets warmer in the sunlight.
Chemical energy is transformed into mechanical energy as the plant grows.
Radiant or light energy (from the sun) is transformed into chemical energy.
What types of energy transformations occur in a battery-operated flashlight? (DOK 2)
Chemical energy to light energy to electrical energy
Chemical energy to electrical energy to light energy
Light energy to chemical energy to electrical energy
What is the most accurate description of the transformations that are taking place in the roller coaster below? (DOK 2)
The roller coaster never has any potential energy because it is always moving.
Potential energy is converted to kinetic energy and back again throughout the ride.
The amount of potential energy is always equal to the amount of kinetic energy throughout the ride.
Which statement best describes how energy is transformed, transferred, and conserved in an ocean food web? (DOK 2)
The total amount of energy in the food web changes as consumers eat producers and then conduct life activities.
Energy is not conserved in an ocean food web because mechanical energy is released from the system as plant-eating fish swim around.
Radiant energy (from the sun) is converted to chemical energy in plants, and then that chemical energy is transferred to the fish that eat the plants.
Ishaan built a simple circuit in science class. He knows that energy transforms within this system. Which of the following statements best describes the energy conservation and transformation in this electric circuit? (DOK 2)
Chemical energy in the batteries is transformed into light and heat energy but does not leave the system.
Chemical energy leaves the batteries and transforms into light and heat energy, and then it is released from the system.
Electrical energy travels from the light bulb to the batteries, where it is stored within the system.
What type of wave is demonstrated in the model below? How is energy transferred through it while it moves left to right? (DOK 2)
Transverse wave; energy travels perpendicular (up and down) to the direction of the wave.
Longitudinal wave; energy travels parallel (in the same direction) to the wave, and particles vibrate.
Longitudinal wave; energy travels perpendicular (up and down) to the direction of the wave.
