Change in Temperature - Endothermic Reaction
Now that learners have been exposed to chemical changes, they learn that some take in heat and therefore, decrease in temperature. The same reaction that they have been investigating between baking soda and vinegar is revisited,...

Chemical Reactions
Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for comparison.

Mass Changes in Chemical Reactions—Microscale Chemistry
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 differences in...
