This 27 slide PPT includes slides covering what waves are, properties of waves, and wave interactions. Also included is a concept map for students to fill out.
I used the concept map for a bulletin board as well
Since uploading this power point, I have made a Waves Bundled Unit that is much more and better than this product. I do not want to delete this product as some people may prefer it over my new one. But please check out my new product before buying!
Check out my Science Word Wall too!
