A nice activity to show the effect of washing woolen clothes in too hot water.
I would come to school wearing a woolen jumper ready for throwing out.
The worksheet gets the student to cut out a jumper shape as a template to put on my jumper and cut out a real wool jumper shape.
10 to 15 shapes can easily be cut from one of my jumpers (which I continue to wear full of jumper shaped holes) this IS funny
The students heat water in a 250ml beaker to different temps (nice investigation) and "wash" their wool jumper shape for a few mins, then see how it has changed by placing it on the second template
