PURPOSE: To compare the experimental mass to the theoretical mass of a product of a chemical reaction. Given the mole relationships in a balanced chemical equation, and the mass of one of the reactants, it is possible to determine the number of moles of every other substance taking part in the reaction.

Lab: Isotopes and Atomic Mass. Suitable for chemistry or for physical science. ($)

Law of Conservation of Mass huh ?

LAB PURPOSE: 1) To practice the techniques used to determine mass and volume 2) To learn to calculate the density of a variety of objects.

Photosynthesis with M&M's. After learning the photosynthetic equations students put their knowledge to work building the molecules in the equation out of M&M's. Students are also reminded of the Law Conservations of Mass. Link to lesson provided.

FREE lab: "Using a Graph to Find Area". Purpose: In this activity, you will be using a sample of ordinary poster board with uniform thickness to study area. Since the thickness is constant, you can measure the mass and area of rectangular poster board samples and graph the data to find a relationship between mass and area (mass/area).

PURPOSE: To calculate the specific heat of a metal using mass and temperature data obtained by using a calorimeter.

This is a test on atomic structure. It is appropriate for a high school physical science or chemistry class. Types of questions include multiple choice, fill in the blank, and computation. Topics covered: atoms, atomic structure, mass and charge of subatomic particles, ions, isotopes, Rutherford, Dalton, Bohr, numbers of protons, neutrons, and electrons in an atom, and calculating the average atomic mass.
