Core Concepts in Chemical Changes
Before diving into the Gizmo activity, it's essential to understand the fundamental concepts of chemical changes:
- Chemical vs. Physical Changes: Chemical changes involve the formation of new substances with different properties, while physical changes alter the form of a substance but not its chemical composition.
- Reactants and Products: In any chemical reaction, reactants are transformed into products through the breaking and forming of chemical bonds.
- Conservation of Mass: The total mass remains constant before and after a chemical reaction, as atoms are neither created nor destroyed.
- Energy Changes: Chemical reactions either release energy (exothermic) or absorb energy (endothermic).
- Evidence of Chemical Change: Color change, formation of precipitate, gas production, temperature change, or odor change.
