Learning Objective: I can explain the steps of the scientific method, compare/contrast observations, and analyze and interpret data to create a model by observing the Great Volume Exchanger demonstration.
Now for the fun stuff...
Ms. Ferro's Invention...The Great Volume Exchanger!
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 $$$$$$$!
It's still in the testing phase of production and isn't commercially available yet, but I can show you the prototype as an example of a natural phenomenon so you can practice using your powers of observation, much as a scientist would.
The GVE in Action
-On the right hand side of your interactive notebook, draw what you see (the GVE setup) independently in your notebook. Leave room underneath for some writing.
-I need a volunteer to read the water volume of the beaker before I pour it in. Record in notes.
-Watch and listen very carefully as I demonstrate the GVE. Observe everything that is done in detail.

-Watch and listen very carefully as I demonstrate the GVE. Observe everything that is done in detail.
-Take a liquid measurement again (volunteer to take volume). Calculate difference between how much went in and how much came out, write down under diagram.
-We have a problem here! What is it? Under your diagram, state the problem briefly in your own words.
-Take 5 minutes independently to form a hypothesis by drawing a cross section of what you think is happening inside the GVE in your notebook. Use observations and be specific, labeling your drawing with an explanation.
-Materials Manager, please get one piece of paper & a marker for your group.
-Now each person will share their ideas with their team, voting for the best idea and drawing it on your team's paper. You can also collaborate to come up with a new group model (hypothesis). (10 mins)
-Reporter in each group shares out the best selected idea. Be able to describe in detail what you think is happening and HOW, and use your drawing to demonstrate it. Be able to answer questions from fellow classmates about your model and how it works.
-Which group's model seems most likely to be the best one, and why?
In science, Occam's razor is used as a heuristic technique (discovery tool) to guide scientists in the development of theoretical models, rather than as an arbiter between published models.[8][9] In the scientific method, Occam's razor is not considered an irrefutable principle of logic or a scientific result; the preference for simplicity in the scientific method is based on the falsifiability criterion. For each accepted explanation of a phenomenon, there is always an infinite number of possible and more complex alternatives, because one can always burden failing explanations with ad hoc hypothesis to prevent them from being falsified; therefore, simpler theories are preferable to more complex ones because they are more testable.

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.

Exit Slip: How do you think you could test your ideas? Write down a proposed experiment to challenge your hypothesis. (5 mins)
