Ask and answer questions while introducing the model to insure active participation and check understanding. This will be a VERY difficult lesson for some students who are not used to thinking on their own. Students gather necessary materials. As their experiments proceed, it is vital that the instructor monitors laboratory procedures and be available for questions. This is what scientists spend their entire lives doing.
Students write up their lab reports and give oral presentations to the class.
This lesson will require students to organize their time over a period of several days.
