These Venn diagrams have students critically thinking about quadratic equations and their structure.
What determines the concentration of a solution? Learn about the relationships between moles, liters, and molarity by adjusting the amount of solute and solution volume. Change solutes to compare different chemical compounds in water.

Add different salts to water, then watch them dissolve and achieve a dynamic equilibrium with solid precipitate. Compare the number of ions in solution for highly soluble NaCl to other slightly soluble salts. Relate the charges on ions to the number of ions in the formula of a salt. Calculate Ksp values.

Amy Smith is an engineer who designs simple and inexpensive solutions to real-world problems. This video produced for Teachers' Domain features her innovative design for testing the safety of drinking water in the developing world.
What happens when sugar and salt are added to water? Pour in sugar, shake in salt, and evaporate water to see the effects on concentration and conductivity. Zoom in to see how different sugar and salt compounds dissolve. Zoom in again to explore the role of water.
Before any instruction occurs on concentration, students use this activity and Tang to build on what they already know about concentration.
Using interactive models embedded in the google doc, students are able to drag and drop to build models of solutions with various concentrations.
