Thread:Changes (4)

This is looking very good. Some suggested changes:

Handouts
Your handout should be a numbered figure in the same format as your other figures.

Math and hypothesis testing connections
It would be important to introduce the concepts of buoyancy. I would also suggest adding a note suggesting weighing 1ml of each liquid to illustrate that a ml of oil does not weigh as much as a ml of water etc. Students could then weigh each liquid and hypothesize the order in which the rainbow will settle out.

Literature connections
Let's expand on this and give more details on how you plan to use the literature

Citations and links
Let's add some more links on density and flotation. Perhaps some links to other activities that explore these concepts.
