A diffusion investigation that can be completed by students using materials they should have at home (provided they have Skittles sweets!). Workbook is taken from my KS3 Diffusion lesson that is also available to purchase (includes this sheet and the low ability version).

This lesson introduces the concept of diffusion and includes a practical activity looking at the diffusion of dye from Skittles sweets. The lesson pack also includes differentiated workbooks (with answers in the lesson slides) for use during the lesson and practical activity.
