1
Why is it so HOT here?? Covering standard E 12 A.4
2
Covering standard E 12 A.4 E 12 A.4 Student know convection and radiation play important roles in moving heat energy in the earths system. E/S
3
CCSD Earth Science Objectives
Syllabus Objectives 4.7, 4.8, 13.5, 13.6 4.8.A SUGGESTION: Demonstrate energy transfer by the following: a. Radiation b. Conduction c. Convection 4.8.B SUGGESTION: Refer to activity Equilibrium from the Earth Science Activities book.

Student Misconception 1
Heat acts as a fluid. (Erickson & Tiberghein, 1985; Stepans, 1994).
5
Student Misconception 2
Heat is a substance which can be added to or removed from an object (Stepans, 1994; Watts, 1983). Heat makes things rise (Stepans, 1994). Cold is opposite to heat (Stepans, 1994).
6
Why would they think that?
Possible source of misconception: nonscientific use of the terms heat and temperature add confusion to this topic. Kinetic molecular theory is too abstract and has little effect at transforming students' ideas.
7
Inquiry Lesson Coming Right Up!
Starter Question: Is heat a substance?
8
Is heat a substance? Does it have mass? Does it have volume?
What is Heat? Is heat a substance? Does it have mass? Does it have volume? Does heat have a shape?
9
Your Assignment, Should You Choose to Accept It…
Challenge 1: Is Heat a Substance?
10
1.Weigh Ice. 2.Melt ice. 3.Weigh Again. 4.Compare Data.
11
What does your data mean?
Lead a discussion. Have kids journal for 5 min. Start a flip book vocabulary assignment. Transfer Endothermic Exothermic
12
Demo Challenge 2 – What makes water mix?
13
1. 2 Earlenmeyer flasks, both 21.C, one dyed blue, one yellow.
2. Card on top, 3. Flip the carded beaker onto other beaker, pull the card. 4.Observe. Repeat with 2 different temperatures. (1 cold, 1 hot)
14
What do your observations mean?
Lead a discussion. Have kids journal for 5 min. Finish vocabulary flip book. Energy Convection Conduction
15
In Conclusion What do YOU think?????????? What can you prove…?
Is heat a fluid? Can it flow through a container? So, is heat a substance? Can you weigh it? What do YOU think?????????? What can you prove…?
