Joining Methods for Timber

Seventh graders are introduced to different ways of joining pieces of timber through a demonstration. Once glue has dried, groups select the joint they believe is strongest and explain why. Groups string all the joints together and pull until a joint breaks. They re-string and pull again, continuing until only the strongest joint remains.
