Climate guide, The Great Volume Exchanger Part 1

-Good morning! Reminder that today & tomorrow we're on tutorial schedule. Come see me during tutorial in room C13 with any questions, concerns, etc.

-Review Climate guide
Period 3: pages 35-39
Period 4: pages 39-55

Let's do science!

-Materials Manager, please get a whiteboard and marker for your group. Leave it in the middle of your table for now.
-Each student please have a piece of paper and something to write with.

The Great Volume Exchanger!

Ms. Ferro's Invention...

The Great Volume Exchanger (GVE) will spontaneously generate liquid matter!!
With our water shortages, you can imagine the potential! We could supply the water needs of an entire community at a fraction of the cost of our current system.

I will make sooo much money $$$$$$$...maybe retire in Central America on the beach...ahhh.

It does require a brief rejuvenation period of 24 hours, undisturbed, to allow the molecules to reconstitute without human intervention.
It's still in the testing phase of production and isn't commercially available yet, but I can show it to you as an example of a natural phenomenon so you can practice using your powers of observation, and also practice trying to figure out how it works, much as a scientist would.

The GVE in Action

-Draw what you see (the GVE) independently on your paper

-Predict what you think will happen when I pour water in the GVE and write it down on your paper. "I think that..."

-I need a volunteer to read liquid measurements

-Watch and listen carefully as I demonstrate the GVE.
-Take a liquid measurement again.
-What's happening? We have a problem here! 
-Take 5 minutes in silence, by yourself, to draw what you think is happening inside the GVE on your own paper. Use observations and be specific.

-Now talk to your team and share ideas, drawing the best one on your team's whiteboard.

-Reporter in each group shares out the best selected idea. Be able to describe in detail what you think is happening and use your drawing to demonstrate it.

-How do you think you could test your ideas?

***I can't reveal my invention yet, it's not copyrighted! ;)

Nature of Science Concepts-GVE

-Models are used in science to explain and predict how things work.

-Science is uncertain because scientists can make more than one workable model to explain their observations.

-We limit the uncertainty through collaboration.

Thanks & see you Friday!
