This is a really neat activity that I originally did with preschool age children, but would also be great with K or grade 1, especially when learning about solids and liquids. It tells you how to make "ocean bottles" that show two liquids that do not go together, but form a neat visual.

Help
I have always loved working with younger students and have done my best to have an opportunity to teach, at least on some level, each of the younger grades.
