- What can kids learn from Beer's Law Lab?
- It helps kids explore: 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.
