Mr. Z’s Introduction to HEAT unit

Do you think its Freezing Here?

Is it Freezing Here?

Is it Freezing Here, or Boiling?

Demonstrate understanding of the term radiate as it applies to the movement of heat AIM: What is Radiation?

AIM: What is radiation?

DO YOU THINK THIS GUY IS FEELING A LITTLE BIT WARM? WHY IS THIS GUY GETTING HOT? AIM: What is radiation?

HOW DOES THE LIGHT AND HEAT FROM THE SUN ARRIVE HERE ON EARTH? AIM: What is radiation?

WHY DO WE LIKE SITTING IN FRONT OF A FIRE PLACE? AIM: What is radiation?

Have you ever put your hand near a hot stove? How did it feel? Why? AIM: What is radiation?

What is this thing called? What does it do? AIM: What is radiation?

{Physics} to send or be sent in rays: to send out energy like heat or light, in the form of rays or waves AIM: What is Radiation

AIM: What is radiation? RADIATION IS ONE OF THREE METHODS IN WHICH HEAT MOVES FROM AN AREA OF GREATER HEAT TO AN AN AREA OF LESSER HEAT. The other two are conduction and convection which we will study later in this unit

AIM: What is Radiation

Do you think this guy is getting warm The heat from the lava is radiating and making this guy HOT! AIM: What is radiation?

How does the light and heat from the sun arrive here on earth? It radiates through space until it reaches the earth AIM: What is radiation?

Do you think the floor of the fireplace is hot? Why? Because the heat radiates from the fire warming the floor beneath it AIM: What is radiation?

{Physics} Radiate means to send to send out energy (like heat or light) in the form of rays or waves. Heat rays. Heat waves. AIM: What is Radiation

Why would you hand get hot above this stove? Because this type of stove ALSO radiates heat AIM: What is radiation?

How does this thing cook food? The microwaves are RADIATED energy? The energy is applied to the food. AIM: What is radiation?

Can we use the theory of Heat Transfer by Radiation to heat a home. How? AIM: What is radiation?

How else do we utilize Heat Radiation? AIM: What is radiation?

How else do we utilize (light) Radiation? AIM: What is radiation? To power this calculator!
