I am currently teaching a unit on in Science on the Life Science area in my fifth grade class that is focusing on Vascular Plants. My Concept map is a work in progress. I am still editing it to make sure it accurately represents the truth. Here is was I have so far. The most difficult part in concept mapping is tring to figure out which map to use. However, I love that fact that you can make this online, print it, insert the map into blogs, powerpoints, ect. I plan to use this in the classroom, and possible print out blank one for my students use. The map created by students can be used for assessment, and inspiration during a course of study.
