Zingy Learning Unit 2 Lessons

Unit 2: Thermal energy transfer

Lesson 1
1) Temperature can be measured in both Fahrenheit and Celcius.
Fill in the table.

Celsius	Fahrenheit
0 -40 C
	0 0 F
0 0 C
10 0 C	50 0 F
20 0 C
0 100 C

2. 
   2)  Your teacher provides you with a cup of water.
   a) What can you do to increase the thermal energy of the water? b) What can you do to decrease the thermal energy of the water?
   
3. 3)  How can you tell if the thermal energy of a cup of water is increasing or decreasing?
   

Unit 2: Thermal energy transfer

Lesson 2

1. 1)  Your teacher brings a cup of hot water to your classroom and places a thermometer in the hot water. For the rest of the classroom period, you observe the temperature of the water decreasing.
   
   1. a)  Why did the temperature of the water decrease?
      (Include the following terms in your answer: thermal energy, transfer, temperature of classroom)
      0
      
   2. b)  If the temperature of the classroom is 72 F, what do you expect the final
      temperature of the water to be after several hours? Explain.
      
2. 2)  Your teacher brings a cup of cold water to your classroom and places a thermometer in the cold water. For the rest of the classroom period, you observe the temperature of the water increasing.
   
   1. a)  Why did the temperature of the water increase?
      (Include the following terms in your answer: thermal energy, transfer, temperature of classroom)
      
   2. b)  If the temperature of the classroom is 720 F, what do you expect the final temperature of the water to be after several hours? Explain.
      
3. 3)  A true story: A friend and I went for a hike on a cold winter day in snowy Montreal. My friend carried her one year old baby on her back. After one hour we sat on a bench for a break. My friend took out a bottle filled with milk from her bag to feed her baby, but the milk was too cold for the baby to drink.
   
   1. a)  How do you think my friend warmed up the milk for her baby? (Hint: Her bag contained some useful things!)
      
   2. b)  Use the following terms to explain why the milk warmed up: thermal energy, transfer, temperature
      

Lesson 3

1. 1)  Why it is preferable to mix a pot of hot soup with a wooden spoon rather than with a metal spoon?
   Include the following terms in your answer: thermal energy, temperature
   
2. 2)  What is the difference between a conductor and an insulator?
   
3. 3)  Provide an example of a conductor.
   
4. 4)  Provide an example of an insulator.
   
5. 5)  In the lesson, Evan conducts an investigation to determine the best material for keeping a drink cold for as long as possible.
   a) What material do you think would work best for keeping a drink cold? Discuss your choice.
   b) Would the thickness of the chosen material affect the rate by which the drink would warm up?
   
6. 6)  Research and explain how a solar cooker can be used to heat food.
   

Lesson 4
1) A student uses a thermometer to measure different objects in her classroom. She
finds that all of the objects in the classroom are at the same temperature.

1. a)  Explain why all of the objects are at the same temperature.
   
2. b)  The student touches the metal legs of a desk. The metal legs feel cold. The student then touches the wooden top of a desk. The wood feels much warmer than the metal legs.
   Explain why the metal legs feel colder than the wooden top?
