Chemical Changes
In Miss Bird’s fifth grade class, we have been talking about chemical changes. We found out that a chemical change is when ingredients are combined and the result is a completely new substance and that it is not reversible. We have been doing a few experiments in our class. In one we combined the reactants (ingredients) of water, baking soda, laundry detergent, and vinegar. The product was that we created a lot of foam. Another experiment was that we grew salt crystals. We combined the reactants of bluing, water, salt and a borax solution.
