Team meeting
You need to be prepared to give a short presentation (30–60 seconds) about one of the following: what you did to make the glues what you did to set up the glues for testing how you might to test the glues any predictions for what you might find out.

Testing the glues
• Set up a testing station • Rest the lolly sticks on
two chairs with a gap between them
• Hang weights on the lolly sticks
• Record what weight they can hold before the glue fails
