These fun activities are not particularly connected, except that they can all be discussed in terms of chemistry. I used them in camp and workshop settings, but can be adapted for the classroom.
Optional: hand out name tags, that depict the molecules to be used in the workshop (see image for baking soda/soda drink/rocket/bubbles lesson).
Introduce the building blocks of chemistry through molecular models, and discuss what they represent.
Do a selection of the activities, focusing on the chemistry in each case.
CAGIS workshop covered baking soda/vinegar reaction, then soda drink, then rocket, then bubbles. Eton Arrowsmith Camp played with molecule models, then did silly putty, soda drink, rocket.
