Types of Chemical Reaction
Identify and describe four types of chemical reaction: combustion (burning in oxygen), oxidation (gain of oxygen), thermal decomposition (breaking down by heat), and displacement (more reactive metal replaces less reactive one)

1 approach
Types of Chemical Reaction means practising the idea at the table with a simple hands-on check. We will demo once, then your child tries.
Materials: A battery, bulb, and wires OR a warm/cool cup comparison setup; Paper for a simple energy-path note. 1. Say the goal of Types of Chemical Reaction in plain words once. 2. Adult shows one energy transfer (circuit lights, or heat moving to a cooler hand nearby) and names the path. 3. Child traces or describes three energy paths and says what changed. 4. Fresh check: one fresh energy-path description. Record and stop. Done: three energy-path notes with a before/after change. Proof: parent note of examples and results. Stop: End after the fresh check; keep optional challenge for another day.

Check understanding
- Writes a word equation for each type of reaction with an example
- Identifies the type of reaction from a given word equation or description
- Explains what makes a displacement reaction happen (relative reactivity)
- Distinguishes complete combustion (CO₂ and H₂O) from incomplete combustion (CO and soot)
“If your child saw iron going rusty and a candle burning, could they explain what type of chemical reaction is happening in each case — and write a simple word equation for one of them?”
