6. What is Heat BrainPop What is Heat? Video
As you watch, write down your own definitions for the following words:
Heat
Temperature

7. What do you think? Answer each question using your plicker
How do molecules at warm temperatures differ from molecules at cool temperatures?
At warm temperatures, molecules move around more
At warm temperatures, molecules grow in size
At warm temperatures, molecules exchange electrons more easily
At warm temperatures, molecules combine with each other more easily

8. What do you think?
What is the difference between heat and temperature?
Temperature measures the motion of molecules, and heat is the energy of that motion
Temperature is measured by a thermometer, and heat is measured by a barometer
Heat is measured in calories, and temperature is measured in joules
Heat is caused by the sun, and temperature is caused by conditions in the atmosphere

9. What do you think?
If you turn on a radiator, heat will diffuse throughout the room. What does this mean?
The temperature will become unbearably hot
The heated molecules will cool down
The heat will be concentrated in one area of the room
The heat will spread out

10. Types of Heat Transfer Lab
Today you will be conducting a mini-lab in which you explore two types of heat transfer
Conduction
radiation

11. Types of Heat Transfer Lab
In this investigation you are expected to
Answer all questions on your lab sheet
Complete both parts of the investigation
Contribute to your groups understanding of heat transfer

12. Convection Demonstration
Watch as convection is shown in water.
What happens when the hot water is placed in the cold water?
What happens to the food coloring when ice is added?
How is heat being transferred throughout the water?

13. Types of Heat Transfer: Conduction
Conduction: the transfer of heat energy from particle to particle between substances through contact or within a substance.
Examples: touching a hot frying pan

14. Types of Heat Transfer: Radiation
Radiation (of heat): transfer of heat energy by emission of electromagnetic radiation in all directions.
Examples: heat energy radiates from the sun to earth

15. Types of Heat Transfer: Convection
Convection: the transfer of heat through the movement of air or liquid currents.
Examples: convection currents in hot water on a stove

16. Exit Ticket
Silently complete your exit ticket. When you are finished, turn it into Ms. Bergman.

28. Vocabulary
Heat: is a form of energy that results from the motion of atoms and molecules.
Measured in Joules (J) 1000 J = 1 kJ
Heat energy always evens out (heat transfers from warm objects to cool objects).
Temperature: a measure of the average kinetic energy molecules have, or how fast they are moving.
Thermal Conductivity: the ability of an object to move heat energy from one part of itself to another.

29. Vocabulary
Calorie: the amount of heat energy required to raise the temperature of 1 g of water 1ºC.

30. Plicker Question
Solid X is placed in contact with solid Y. Heat energy will flow spontaneously from X to Y when
X is 20ºC and Y is 20ºC
X is 10ºC and Y is 5ºC
X is -25ºC and Y is -10ºC
X is 25ºC and Y is 30ºC

32. Switch Documentary This unit is all about heat and energy.
The energy industry is one of the largest in the world. This documentary looks at how the energy industry works, and how the world can move towards using renewable energy that doesn’t rely on burning fossil fuels which put CO2 into the atmosphere contributing to global warming.
