What is something that prevents the transfer of energy?
The transfer of heat by direct contact.
what is conduction
Potential Energy is based on______ and _______.
What are mass and position
The energy of motion.
What is Kinetic Energy
Heat always moves from ______ temperature to ______ temperature.
What is Higher to lower or warmer to colder
What is conductivity?
What is the ability to transfer energy
The transfer of heat by currents (either in air/gasses or water/liquid).
What is convection
Which has greater potential energy?
Bowling ball or ping pong ball
What is Bowling Ball
Stored energy due to position or condition.
What is Potential Energy
Thermal energy depends on temperature and the number of ______.
What are Particles
Conduction occurs most easily in these types of materials.
What are metals
The transfer of heat by electromagnetic waves.
What is radiation

What is on top of the cabinet
What are 3 ways is Heat transfered?
What is radiation, conduction, and convection
Which object is the best conductor?
Tires on a car, metal spoon, cotton tshirt
What is metal spoon
This everyday object is designed to reduce conduction and prevent burns.
What is a hot mitt
This natural process causes wind and ocean currents.
What are Convection Currents
As a skateboarder goes down the ramp, explain what is happening to the kinetic and potential energy.
What is potential energy decreases and the kinetic energy increases
As the motion of particles increases, thermal energy ______.
What is increases.
A metal spoon feels hotter than a plastic spoon because it _______.
What is because Metal has higher conductivity
If two objects are touching (direct contact), thermal energy will transfer by this method.
What is Conduction
Warm fluids and gasses rise because they are ______ dense.
What is LESS dense
Explain what happens to a roller coaster's potential and kinetic energy as it climbs the hill.
What is the kinetic enregy decreases and the potential energy increases.
