This activity is suggested for Halloween, but I feel it can be suitable for any festive occasion, decorating the rubber gloves as “bouquets” or even using thinner water balloons instead. This site does very well in giving ample background information and thorough explanation of what is being observed in the activity. It first addresses the bigger questions and ideas of the lesson and proceeds to explain through the use of large scale examples and follow-up activities. Some terms and vocabulary, such as diffusion, may be unfamiliar to some learners and would benefit from additional supplementary visuals or animations.
