Lola placed a flask of room-temperature water over a flame. When the water started to boil, she placed a room-temperature copper rod into the flask. During the experiment, Lola wrote the four notes shown above in her lab journal. Which notes are observations supporting the idea that energy can be transferred from one place to another? Select each correct answer. More than one answer may be correct
It is harder to see through the water when it is boiling.
The temperature of the water went up when it was over the flame.
The flask containing the boling water was made of glass.
After five minutes in the flask, the end of the copper rod was hot to the touch.
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.
thermal -> sound -> electrical
thermal -> light -> chemical
light -> electrical -> sound
light -> chemical -> electrical
Energy is changed from one form to another during an energy transformation. Which of the following is an example of a transformation of electrical energy into another kind of energy?
a light bulb lighting up
a motor making a noise
a heater feeling warm
all of these
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.
Sean could put solar-powered lights on the bike. After sitting in the sun all day, the lights will shine when turned on.
Sean could put electric lights on the bike. Then he could use batteries that can be charged every night by hooking them up to an electrical outlet.
Sean could put electric lights on the bike. Then he could use a small windmill to change the energy of the bike's motion into electricity for the lights.
Sean could put reflectors on the bike. When light hits the reflectors, it will bounce off in many directions.
Electrical energy can produce many other types of energy. When electricity runs through a light bulb, what other type of energy is produced?
light energy
mechanical energy
chemical energy
sound energy
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?
use moving air to produce stored energy
use light energy to move air
use moving air to produce light energy
use stored energy to move air
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?
Some of the light energy from the asphalt is transferred into heat energy in the Sun.
Some of the heat energy from the asphalt is transferred into light energy in the Sun.
Some of the light energy from the Sun is transferred into heat energy in the asphalt.
Some of the heat energy from the Sun is transferred into light energy in the asphalt.

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?
sound
light
energy
strength
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?
Some of the sound energy from the air is transferred into electrical energy in the lawn mower.
Some of the sound energy from the lawn mower is transferred into electrical energy in the air.
Some of the electrical energy from the lawn mower is transferred into sound energy in the air.
Some of the electrical energy from the air is transferred into sound energy in the lawn mower.

The Sun warming your face on a sunny day.
A microwave heating food.
A fan blowing air across a room.
In an experiment, a student places a thermometer in a cup of hot water and observes the temperature rise. What type of energy transfer is primarily responsible for this change?
Conduction
Convection
Radiation
Evaporation
Which of the following real-world applications involves the conversion of kinetic energy to electrical energy?
