Does Size Matter?

Middle schoolers identify that the variables that affect the chemical concentration of a solution. Then they use molecule models to relate the mass of the molecule to its size dimensions and gain understanding of how the mass of a molecule effects the concentration of said molecules present within a given volume. Students also analyze the physical properties of chemical solutions using pH indicators and acid/base neutralization techniques.
