This is in good shape. Minor suggestions for the most part. The video is most important

Even if it means setting it up again:

Alka-Seltzer
Add a tag in the materials that looks like this:  

next steps
Certainly add the chemistry piece here. You have citric acid and baking soda in the tablets. Once moist, the two ingredients mix, react, and release CO2. Get the full reaction from the wikipedia article. Edit the wikipedia article, copy and paste the formula, and then cite your source.

Link this to the density rainbow activity. What would happen with alka seltzer in there?

Lesson plan
number 2: rephrase. Perhaps when the three ingredients are mixed. Also, I think students need some more guidance. What is their basis for formulating a hypothesis?

Math connection
I don't really see math here. Simply measuring is not enough. If just measuring is a legit standard, then link right to it. But definitely add an artistic connection. You could mix colors, you are making a craft, and you could mess with light color to get other effects. A strobe light would add a very interesting effect.
