What better way is there to introduce conservation of mass than a few simple experiments? Young chemists conduct two chemical reactions, take the masses of reactants and products, then compare their results to determine...

How do you teach a student with visual impairments about the conservation of mass? You use tactile models that represent the theoretical concept. Baking soda and vinegar are used to add gas to a deflated balloon. Learners will feel the...

Because atoms are neither created nor destroyed in a chemical reaction, the total mass of products in a reaction must be the same as the total mass of the reactants.

Students use a Conductivity Probe to measure change in conductivity during a chemical reaction and determine the equivalence point of the reaction They determine the mass of the product and calculate the molar concentration of the...
