CRITICAL SAFETY WARNING
Chemistry experiments involve real chemical reactions that can be dangerous if done improperly. Before attempting ANY experiment:
- ALWAYS have adult supervision for minors
- ALWAYS wear safety goggles and gloves
- NEVER mix unknown chemicals "to see what happens"
- NEVER taste or intentionally inhale any chemical or reaction product
- NEVER heat sealed containers
- NEVER dispose of chemicals down the drain without checking safety data
- Work in well-ventilated areas
- Keep a fire extinguisher accessible
- Know the location of the nearest eyewash station (or clean running water)
- Review Safety Data Sheets (SDS) for every chemical you use
If there is a spill, splash in eyes, or any emergency, stop immediately and address safety first.

Understanding Reactions
Types of Chemical Reactions

- Decomposition: AB -> A + B (hydrogen peroxide -> water + oxygen)
- Single replacement: A + BC -> AC + B (zinc + copper sulfate -> zinc sulfate + copper)
- Double replacement: AB + CD -> AD + CB (baking soda + vinegar -> sodium acetate + CO2 + water)
- Combustion: Fuel + O2 -> CO2 + H2O + energy
- Acid-base: Acid + Base -> Salt + Water
Key Concepts to Explore
- Conservation of mass: Matter is not created or destroyed in reactions
- Energy changes: Exothermic (releases heat) vs endothermic (absorbs heat)
- Reaction rate: Temperature, concentration, surface area, and catalysts
- Equilibrium: Some reactions reach a balance point
- pH: Logarithmic scale of hydrogen ion concentration (0-14)
Science Fair Applications
Choosing a Strong Project
