Where does my trash go after it leaves my house?


After you answer this question, look at the picture and talk about this idea. (The picture may be confusing: the idea is trash in a volcano.)

We must postulate/posit ideas before we can test them and then make use of them! Making use of them is the goal.



FYI:


postulate- 

v. suggest or assume the existence, fact, or truth of (something) as a basis for reasoning, discussion, or belief.


posit- 

v. assume as a fact; put forward as a basis for argument
