These are simple ways to demonstrate water chemistry concepts such as adhesion, cohesion, and polarity to students in a hands on way using easy to find and inexpensive lab materials. The lesson was originally designed to align with a biology course to teach the impact of water on life, but it could also be modified to fit a chemistry or physical science curriculum.

In this activity, students interact with 12 models to observe emergent phenomena as molecules assemble themselves. Investigate the factors that are important to self-assembly, including shape and polarity. Try to assemble a monolayer by "pushing" the molecules to the substrate (it's not easy!). Rotate complex molecules to view their structure. Finally, create your own nanostructures by selecting molecules, adding charges to them, and observing the results of self-assembly.

Investigate what makes something soluble by exploring the effects of intermolecular attractions and what properties are necessary in a solution to overcome them. Interactive models simulate the process of dissolution, allowing you to experiment with how external factors, such as heat, can affect a substance's solubility.
