Demonstration: Introduction to Solutions Mark as Favorite (5 Favorites)
In this demonstration, students will recognize that there is a threshold for the amount of salt that can be dissolved into a specified amount of water. Students will be asked to make observations about two different salt water samples to determine if a sample that contains undissolved salt is still considered a solution. The saltiness, or salinity, of the water samples will be used to help students make connections about how the melting of polar ice caps is changing the average salinity of the ocean.

Animation: Solubility Animation Mark as Favorite (76 Favorites)
This animation explores how ionic and molecular compounds dissolve (or don’t) in water. Students will see that if an ionic compound such as salt dissolves, the ions dissociate, whereas the molecules in a molecular compound such as sugar remain intact but are separated from one another by water molecules. They will also see that some ionic compounds such as chalk do not dissolve, and the cations and anions remain stuck together. **This video has no audio**

Lab: Winter Crystals Mark as Favorite (43 Favorites)
In this lab, students will create a supersaturated solution by dissolving borax in boiling water. They will create a snowflake using pipe cleaner to suspend in the solution, which will serve as a nucleation site for crystallization as the solution cools and remains undistributed overnight. This lab gives students an opportunity to experience the exciting crystallization process and become more familiar with an engaging chemistry spectacle!
