GOODNESS, GRACIOUS, GREAT BALLS OF FIRE Page _____
You rush home from a hectic day at school hoping you received another email from Stormin’ Stan. “Please, please, please let there be an email,” you say aloud. “Maybe he’ll tell me that I’ve done all the research I need to do. Sure enough, there’s a new email from Stormin’ Stan.
Objective: Students will differentiate amongst conduction, convection, and radiation in order to describe how heat can be transferred in Earth’s atmosphere.
Activity 1
- Observe the materials in the teacher demonstration.
- Draw arrows on the diagram to predict how the food coloring will move in water.
PredictionActual
3. Provide a possible explanation for why the food coloring behaved as it did in the beaker. Use prior knowledge to support your response.

“Beakersof water? What does that have to do with weather? Do you have any idea what you’re doing??”
/ WWW: Stan? Are you there?/ SS: Not you again! Don’t you ever leave your computer?
/ WWWI was wondering, why did you send over that demonstration? It showed me movement of water, but I thought I was supposed to find out about heat transfer in air. Did I miss something?
/ SS: No, kid, you’re on the right track. The demonstration I sent was just to show you how particles in a fluid move when they are heated. Water is a fluid, but so is air. Since we can’t necessarily see the particles in air move, I figured I’d send you a demonstration that you could see. Make sense?
/ WWW: Yeah. I couldn’t convince you to tell me about heat transfer, could I?
/ SS: No! But, why don’t you send me a quick email when you’re finished researching and tell me what type of heat transfer you observed in the beaker? That way I can see if you’re on the right track!
