PhET sims are fun, interactive, research-based simulations of physical phenomena developed by the PhET™ project at the University of Colorado. Conversion to HTML5 and tablet compatibility supported by the Royal Society of Chemistry.
Sample Learning Goals:
- Describe the relationships between volume and amount of solute to solution concentration.
- Explain qualitatively the relationship between solution color and concentration.
- Predict and explain how solution concentration will change for adding or removing: water, solute, and/or solution.
- Calculate the concentration of solutions in units of molarity (mol/L).
- Design a procedure for creating a solution of a given concentration.
- Identify when a solution is saturated and predict how concentration will change for adding or removing: water, solute, and/or solution.
- Describe the relationship between the solution concentration and the intensity of light that is absorbed/transmitted.
- Describe the relationship between absorbance, molar absorptivity, path length, and concentration in Beer’s Law.
- Predict how the intensity of light absorbed/transmitted will change with changes in solution type, solution concentration, container width, or light source, and explain why.
