Sean loves riding his bike, but his parents will not let him ride it in the evenings. They say that it is dangerous because drivers cannot see him from very far away. Sean thinks of several solutions that could solve his problem. Which of these solutions would change stored energy into light energy? Select EACH correct answer. More than one answer may be correct.

Look at the circuit above. Where would you look to find evidence of energy transfer?

Kelly has two toy cars. Both cars have the same mass, but each car has a different electrical circuit inside. These electrical circuits convert electrical energy into motion energy which causes the cars to move. How could Kelly find out which car converts the most electrical energy into motion energy?

Electrical energy can produce many other types of energy. When electricity runs through a light bulb, what other type of energy is produced?

Above is a sketch Wilton made of his solution to an engineering design problem. When the fan spins, the light bulb turns on. What was Wilton's solution designed to do?

Stevan is playing in the park on a sunny summer day. The park he is playing at has both grass and asphalt. Stevan notices that the asphalt feels hotter than the grass in the park. What statement explains the energy transfer in the asphalt?

Wayne and his family are designing a passive solar heater to keep their barn warm in the winter. A passive solar heater converts light energy into heat energy. What is the most important information for Wayne and his family to consider in their design?

A solar panel collects light from the Sun. The light can then be used to make electricity. In this example, _______ was transferred from the Sun to the solar panel.

Electrical energy can produce many other types of energy. When electricity runs through an electric stove, what other type of energy is produced?

Ian built a simple circuit using wires, a battery, and a bell. When Ian connects the wires to the battery, an electric current passes through the wire and the bell rings. What is transferred by the electric current?

A gardener is using a lawn mower to cut his grass. His lawn mower uses electricity instead of gasoline. When he turns on the lawn mower, it makes a constant, loud noise. He has to wear ear plugs to protect his hearing. What statement explains the energy transfer in the lawn mower?

Carmen built the electrical circuit shown above. When the switch is closed, electrical energy flows through the circuit. However, when Carmen closes the switch the light bulb is so dimly lit that it is hard to tell it is glowing. What is the best way for Carmen to refine the circuit so that the light bulb glows brighter?

Betty is using the microwave to cook her lunch. She knows that the microwave changes electrical energy into heat energy to cook food. What evidence does Betty have that the microwave changes electrical energy into heat energy?

Which statement describes the flow of energy through the television set?

Sean loves riding his bicycle, but his parents won't let him ride it in the evenings. They say it's dangerous because drivers can't see him from very far away. Sean used the engineering design process to solve this problem. He made a simple circuit with two lights, a battery, and a switch. He attached one light to the front of his bicycle and the other to the back. Sean's friend Dean agreed to help him test his bicycle lights to see if they meet the criteria for success. What should Sean and Dean measure?

Sandy bought a lamp to put in the corner of her living room. After she plugged the lamp into the outlet, she turned on the light switch and the bulb glowed. What statement explains the energy transfer in the lamp?

Which of the following is a way that energy transfer can be shown in a circuit?

Electrical energy can produce many other types of energy. When electricity runs through the speaker of a stereo, what other type of energy is produced?

George is playing his electric keyboard, and his friend Tonya can hear the song he is playing. Which statement describes the flow of energy through the keyboard as George plays?

Antoinette has a big clock in her living room. She has to wind the clock by turning a key. Winding the clock makes Antoinette's hand tired. She decides to use engineering design to find a better way to wind her clock. She asks her friends for help. Each friend makes a prototype of a clock winder. Each prototype uses a different source of energy to wind the clock. Remember that the clock winder must be used inside Antoinette's living room. So whose prototype best fits the criteria for success?

Jamal has a fan that plugs into the wall. When Jamal plugs in the fan and turns it on, the blades spin and make the air around them move. Jamal's fan uses _______ energy to cause motion.

Jamal has a fan that plugs into the wall. When Jamal plugs in the fan and turns it on, the blades spin and make the air around them move. Jamal's fan uses _______ energy to cause motion.

The diagram below represents a series of energy transformations. The Sun transfers a certain type of energy to a solar panel. The solar panel transforms that energy into another form. The energy is then transferred to a music speaker. The speaker transforms the energy again and then transfers it through the air. Which type of energy is associated with each transfer? Select the correct order above.
