1. Thermal Energy Lab Core Lab 4 th 6 Weeks

2. What you can expect to see: Station 1 : Beaker of water on hot plate. Station 2 : Lamp with regular bulb. Station 3 : Pie plate cut into a spiral. Station 4 : Wax on Conductometer Station 5 : Campfire (simulated) and Sun (simulated) Station 6 : Lava Lamp

3. Thermal Energy Lab Write the 3 types of heat transfer & a few key words to describe them. Write the Law of Conservation of Energy Write Station 1 – Station 6 on the next few pages & draw a horizontal line half way down the page on each one.  You will be drawing your observations on the top half & answering the questions on the bottom half.

4. For each STATION On the top half of the page, draw a picture of the items at this lab station. Be very neat and clear and label the parts of your drawing. Make it large enough so you can see details. On the bottom half of the page, answer the questions in complete sentences.

5. STATION ONE

6. STATION ONE QUESTIONS 1.Describe how you think the heat is moving through the hot plate, pot, and water at this lab station. Assume that the water was cold when we put it in the pot. 2.On your drawing, draw a dotted red line to show how heat is moving through the objects. 3.Are the objects touching each other? 4.Do you think the objects HAVE to be touching each other for the heat to moving through them? 5.Give another example you have seen in your life when heat moved from one object to another this way.

7. STATION TWO

9. STATION TWO QUESTIONS 1.Describe how you think the heat is moving from the lamp to your hand at this lab station. BE SURE YOUR HAND IS NEVER TOUCHING THE LAMP. 2.On your drawing, draw wavy red lines to show how heat is moving from the object. 3.Can you see the heat moving from the source to your hand? 4.What happens as you move your hand further away from the lamp? 5.Give another example you have seen in your life when heat moved from one object to another this way.

10. STATION THREE http://www.youtube.com/watch?v=aXaxoHa1M0w

11. STATION THREE QUESTIONS 1.Describe how you think the heat is moving from the hot plate, spiral, and string at this lab station. 2.On your drawing, draw a dotted red line to show how heat is moving through the objects. 3.What do you think is causing the pie plate spiral to move? 4.Do you think a plastic spiral would work as well? Why or why not?

12. STATION FOUR http://www.youtube.com/watch?v=2FZ31tV0dno

13. In order from left: aluminum, brass, steel (iron), nickel and copper.

14. STATION FOUR QUESTIONS 1.As the wax falls off the stems, write the name of the material the stem is made of. 2.What do you think is causing the wax to fall off the stems? 3.Would this activity work if the stems were made of wood? Why or Why not? 4.On your drawing, draw a dotted red line to show how heat is moving through the objects.

15. STATION FIVE

16. STATION FIVE QUESTIONS 1.What do you think would happen to a marshmallow held near the campfire? What do you think would happen to a planet or comet near the Sun? 2.What do you think is effecting the marshmallow or planet? 3.On your drawing, draw a dotted red line to show how heat is moving from the objects to the other objects. Draw in a planet or marshmallow. 4.Are the objects touching? 5.What is the heat traveling through? 6.Does the heat need something to travel through in order to travel?

17. STATION SIX http://www.youtube.com/watch?v=jUv4Cid3OnE

18. STATION SIX QUESTIONS 1.What happens when the lava lamp is off? Look at the lava lamp that is off and describe it. 2.On your drawing, draw a dotted red line to show how heat is moving from the objects to the other objects. 3.What happens when the lava lamp is turned on? 4.What is causing the material to move? 5.Why do you think the “goo” on the bottom rises? 6.Why do you think the “goo” on the top sinks back down?

19. Finish up! Make sure you have completed all drawings and questions. Turn in to Mrs. Haas for grading!
