Overview: |
In this lesson, students observe chemical reactions that produce obvious effects (as opposed to reactions in which the substances appear not to change at all). They begin by exploring a different substance every day for one week. They compare the substances and learn that substances can be solids, liquids, or gases. Next, through teacher demonstration (or direct, supervised student involvement), students watch what happens when sand and water are mixed together (no chemical reaction), and when several pairs of acids and bases are mixed together (a chemical reaction occurs). Students then get to build their own "film canister rockets," using baking soda and vinegar as rocket fuel. This lesson concludes with open-ended thinking when students are asked to determine where rust comes from. |
Content Standard(s): |
Science SC2015 (2015) Grade: 5 | 2 ) Investigate matter to provide mathematical evidence, including graphs, to
show that regardless of the type of reaction (e.g., new substance forming due to
dissolving or mixing) or change (e.g., phase change) that occurs when heating,
cooling, or mixing substances, the total weight of the matter is conserved.

| Science SC2015 (2015) Grade: 5 | 4 ) Investigate whether the mixing of two or more substances results in new
substances (e.g., mixing of baking soda and vinegar resulting in the formation
of a new substance, gas; mixing of sand and water resulting in no new substance
being formed).
