One of the most important tools that scientists use is not something you can see or touch. Instead, science gets much of its power from the way it organizes questions and investigations. By using a structured approach that all scientists share in common, it is possible to test out ideas in a way that is logical, repeatable, and based on evidence. You will often see this referred to as the scientific method, the basic structure of which you can see here: Scientific Method
For this week's discussion, you will engage in a little scientific inquiry of your own, using the following scenario:
What’s in the can?

He asks you to help him figure out what is inside. There is one catch: He does not want to open the can, just in case there is something expensive inside. During this week's discussion, your instructor will play the role of the Circus Supermarket store manager. Your instructor will answer any questions you have about the can, and you should keep all the answers to all the questions asked in mind as you work on a theory about what is in the can.
After you have asked at least two questions of your own and have read the answers to all the other questions your classmates have asked up until that point, you should come up with and post a specific, testable hypothesis about what is in the can.
You should also request that the store manager do things to the can and then report back the results to you. For example, if you would like to ask, "What sounds do
