Thermal Energy 6th Grade

What About Heat? Do really cold things, like ice cream and snow, have heat? Discuss with your group members and write your response on your board. Day 1

What is Thermal Energy? Your thermal energy packet says: All materials are made of tiny particles called molecules. These molecules are always moving. The movement of these molecules creates heat. The amount of heat created depends on how fast the molecules move. The faster they move, the hotter it will get. Day 1

Thermal (Heat) Energy Packet Let’s Review! With your partner: Share an important fact from your heat energy “wheel” Go over your answers from the Sharpen Your Skills section Discuss question #1 (the refrigerator vs. the freezer) Share the question you selected under Making Connections along with your response Think about questions you have along the way. We will discuss them as a class.  Day 2

Bill Nye on Heat Check your response from the last question. Were you correct? Day 1

Melt Off Exploration Data:

Melt Off Exploration (Reflect/Pair/Share) If you had a dish of ice cream and wanted it to stay a solid, what are some things you could do?

Heat on the Move data

Heat on the Move (Reflect/Pair/Share) What type of materials allowed heat to pass through them easily? Which did not? If I set a cup of hot cocoa on the table and leave it there for 5 hours, what happens?

Demo What kind of chart would your draw to record your data? Try it on your white board. Paper Clip #1 #2 #3 Time to Drop (sec.) Day 1 – Conduction demo – paperclips on wire

Demo Think-Pair-Share What caused the paper clips to drop? Why did they drop in the order they did? What was going on in the wire? Was the demonstration an example of conduction, convection, or radiation? Day 2

Add the following definitions to your foldable  Day 2

Conduction Heat is transferred THROUGH molecules Transfer through contact (objects touching) Occurs in solids Day 2

Day 2

4 Day 2

Convection Heat transferred through moving gas (air) or liquid (water) Less dense (warm) rises More dense (cool) sinks Day 3

Radiation Transfer of heat through waves Usually includes light – Sun, fire, light bulbs

Back of Foldable Thermal energy ALWAYS transfers from warmer to cooler objects. Molecules are always moving. More thermal energy = faster moving molecules

Similarities and Differences Matrix Thermal Energy Transfer Name: Hour: Conduction Convection Radiation How is the thermal (heat) energy transferred or moved from place to place? In what state of matter does the thermal energy transfer occur? How do the molecules move during the thermal energy transfer?

Similarities and Differences Matrix Thermal Energy Transfer Name: Hour: Conduction Convection Radiation How is the thermal (heat) energy transferred or moved from place to place? Heat moves through an object. Molecules only vibrate. Movement of molecules moves the heat. Light waves travel and heat up an object In what state of matter does the thermal energy transfer occur? Solids Liquids and Gases No Matter Needed How do the molecules move during the thermal energy transfer? Bump into each other – stay in place Move around – warm rises, cool falls No Matter = no molecules

Thermal (Heat) Energy Transfer Stop and Draw You have three minutes to draw what comes to mind when you think about these two concepts. Thermal (Heat) Energy Thermal (Heat) Energy Transfer

Radiation Demo In the summer, what color clothing would you wear if you wanted to remain cooler? Box covered with white paper Box covered with black paper Day 4
