C.E.R.
What does “C” in C.E.R. stand for?
Claim
What tool do we use to measure temperature?
A thermometer.
What are the three ways heat can move?
Conduction, convection, and radiation.
What is thermal energy?
The total energy of motion of all particles in an object.
What are all things made of?
Particles (atoms or molecules).
What is a claim?
Your answer or statement that explains what you think.
Heat always moves from ______ to ______.
Hot to cold.
What type of heat transfer happens when you touch a metal spoon in hot soup?
Conduction.
When you heat something up, does it gain or lose thermal energy?
Gain.
What happens to particles when something gets hotter?
They move faster.
What does “E” stand for?
Evidence.
What is the difference between heat and temperature?
Heat is energy transfer; temperature measures particle motion.
What type of heat transfer causes warm air to rise and cool air to sink?
Convection.
What is one thing that affects the amount of thermal energy in an object?
Temperature, number of particles, and how the particles move.
What happens to particles when something cools down?
They move slower.
What is quantitive data?
data involving numbers
If you put an ice cube in warm water, which way does the heat move?
From the warm water into the ice cube.
What type of heat transfer allows the Sun’s energy to reach Earth?
Radiation.
Two objects have the same temperature. Which has more thermal energy—the small one or the large one?
The larger one (it has more particles).
How can we tell how fast particles are moving?
By measuring temperature. (Thermal energy)
What is reasoning in a C.E.R.?
It explains how your evidence supports your claim.
You’re holding two cups of cocoa: one at 90°F and one at 130°F. Which has faster-moving particles.
The 130°F cocoa has faster-moving particles, so it has a higher temperature.
Why does a metal spoon feel colder than a wooden one at room temperature?
Metal conducts heat faster (takes heat from your hand).
What happens to thermal energy when a hot object touches a cold one?
It transfers from the hot to the cold object.
When thermal energy is added to a solid, what happens to its particles?
They move faster and spread apart.
