Vocabulary
A substance that does not allow the flow of electrical
charge or transfers thermal energy easily through matter
Insulator
What are the ways thermal energy can be transferred?
Convection, Conduction, Radiation
Glow Lab: The glow sticks in the HOT water were glowing __________ (brighter / dimmer) than the glow sticks in the cold water because the molecules had more energy.
Brighter! Warm = more energy = brighter glow stick
How can you tell if something is living?
If it has cells!
A substance that allows the flow of electrical
charge or transfers thermal energy through matter
Conductor
Transfer of thermal energy that occurs in solids,
liquids, and gases when two substances of
different temperatures touch
Conduction
Beaker Mystery Lab: We put COLD water into a beaker of WARM water. Over time the temperatures started going towards equilibrium. This was to prove that thermal energy flows from _______ to ________.
hot to cold
What is the main function of the circulatory system?
To circulate (pump) blood throughout your body.
The total kinetic (motion) energy of the tiny particles
that make up matter; the faster the particles move,
the warmer the matter becomes
Thermal Energy
Heat transfer caused by the rising of hotter, less
dense fluids and the falling of cooler, denser fluids
Convection
While our penguins were on the beach thermal energy was flowin! Did it flow from the beach to the igloo or from the igloo to the beach? WHY?
Beach to igloo because heat moves from HOT (beach) to COLD (cooler igloo)
The higher up something is, the __________ potential energy it has.
more
The ability of a system to do work; required for changes to happen within a system
Energy
Conduction
In class we observed a lava lamp. This is an example of what kind of heat transfer?
Convection.
When water vapor turns into a cloud, this phase change is called what?
Condensation
A measure of how much matter is present in a
substace
Mass
DEFINE radiation.
The transfer of energy by the movement of
electromagnetic waves or subatomic particles
We used a simulation to show when a substance is heated, molecules will _________________ kinetic energy.
Increase
Why does the equator have a warmer climate than the poles?
The equator gets more direct sunlight.
