True or False. Heat energy can be transferred when objects touch, are near each other or are even in the same room as each other.
What is true?
100
A ______________________ effectively transfers heat energy.
What is a conductor?
100
Blankets are effective in keeping you warm for this reason.
What is they slow the transfer of heat energy from your warm body to the cold air?
200
Energy present in moving things
What is Motion Energy?
200
The definition of an energy transfer.
What is when energy MOVES from one object to another or CHANGES from one form to another?
200
The tool to measure heat energy.
What is a thermometer?
200
___________________ is when heat energy is transferred through materials.
What is conduction?
200
The reason why cold lemonade gets warmer after sitting on your kitchen counter.
What is the heat energy from the air is transferred to the colder glass of lemonade, warming it up?
300
Energy stored in stretchy objects
What is Elastic Energy?
300
Change cannot happen without this.
What is energy?
300
Consider our lab with the warm water in the cold water. This happened to the temperature of the COLD water.
What is the temperature increased?
300
True or False. An insulator speeds up the transfer of heat energy.
What is false? (an insulator SLOWS the transfer of heat energy)
300
The energy transfers in a Nerf gun.
What is motion (pulling the trigger) -> elastic (the spring in the gun) -> motion (the arrow flying out) -> gravitational (the arrow falling to the ground?
400
Energy stored in objects that are in a position to fall.
What is Gravitational Energy?
400
A _________________ is a device that helps people harness energy transfers to perform a particular task.
What is a machine?
400
Consider our lab where we placed the bag of hot water into the cold water. This is why the temperature of the cold water changed.
What is because the heat from the warm water was transferred to the cold water?
400
An example of a good conductor.
What is copper, aluminum, metal? (answers may vary)
400
The energy transfers in a battery powered boat that has a siren.
What is chemical energy (in the battery) -> motion (the movement of the boat) -> sound (the buzzing of the boat's motor and the sound of the siren) and light (the siren flashing)
500
When you are at the top of a roller coaster, poised to come down a giant drop __________________ energy is present.
What is Gravitational Energy?
500
Three examples of machines.
What are bikes, trains, pencil sharpeners, paper shredders? (answers may vary)
500
True or False. Some materials transfer heat energy better than others.
What is true?
500
An example of a good insulator.
What is foam, cotton, brick? (answers may vary)
500
The packaging of a cookie sheet advertises that it is a "good conductor" for this reason.
What is conductors are effective at transferring heat energy, so a baking sheet that is a good conductor would transfer heat quickly and evenly, ensuring that the cookies bake properly?
