The evidence of a chemical change in the fireworks includes:
- **Color change (E)**: Fireworks produce different colors due to the chemical reactions of various metal salts when burned.
- **Temperature change (B)**: The combustion of the chemicals in the fireworks produces heat, resulting in a change in temperature.
- **Light production (D)**: The chemical reactions in fireworks emit light as a result of the energy release, which is a key indicator of a chemical change.
So the three correct responses are **E (Color change)**, **B (Temperature change)**, and **D (Light production)**.
- **Color change (E)**: Fireworks produce different colors due to the chemical reactions of various metal salts when burned.
- **Temperature change (B)**: The combustion of the chemicals in the fireworks produces heat, resulting in a change in temperature.
- **Light production (D)**: The chemical reactions in fireworks emit light as a result of the energy release, which is a key indicator of a chemical change.
So the three correct responses are **E (Color change)**, **B (Temperature change)**, and **D (Light production)**.
