Concept Mapping

This concept map gives the student a visual of the differences between the two basic cell types.  If I upgraded my account I would embed images into the links with a thorough explanation.  This is a basic Biological concept which is easier to understand broken into two separate groups.  I would give this to students as a study aid that would assist them in preparation for the test.
I have used concept mapping in my classroom before and found it to be very helpful to students.  This helps them make the connections between objects.  Usually there are blanks on the map that the students will need to fill in to complete the map.  This is a great group activity as it helps to generate conversation.
