Project Title: Chemical Reactions and Energy
Objective: Identify reaction types, balance equations, and explain energy changes.
Project Instructions:
- 1. Identify three common chemical reactions from daily life.
- 2. Classify each as combination, decomposition, or displacement.
- 3. Balance two chemical equations.
- 4. Label one reaction as exothermic or endothermic with reasons.
- 5. Consult your coach where necessary.
Evidence to Submit:
- • Reaction examples and types.
- • Balanced equations.
- • Energy change explanation.
Submission
Part C: Training Others
Teach a peer about reactions and energy changes.
Guidance:
- • Explain types of reactions with examples.
- • Demonstrate how to balance an equation.
- • Discuss exothermic vs endothermic reactions.
Reflection:
- • What did the learner understand well?
- • What needed more explanation?
- • What support do you need from your coach?
