I spent hours wading through chemistry jokes to find these that are at the right level for 8th or 9th grade physical science students. They are approximately in order of a typical unit on the Periodic Table, Chemical Bonds, and Chemical Reactions. 17 jokes are included in this PowerPoint file.
Share one each day with your 8th or 9th graders and watch their faces as the meaning of the pun dawns on them.
Last year, the 8th graders on my FIRST Lego League team loved Chemistry Cat so much that they put him on their team t-shirt!
