Cantilever Discovery Activity

My grade sevens were busy doing their great spaghetti cantilever o'science building challenge.  We talked about cantilevers while making a human cantilever in class with a long 2 x 8 board, a classroom table and the students as parts of the cantilever.  Then, it was time for them to try one for themselves.  They were given 25 pieces of uncooked spaghetti, 30 cm of tape and 60 cm of string.  After we tested their creations, we then did our notes on cantilevers and did a little classroom/school grounds search-and-find for cantilevers in real life.  Two periods of fun and learning.
