- If something is outside during the day then that something will receive sunlight
- Puddles of water are outside during the day
- Hence, puddles of water will receive sunlight

- Puddles of water will receive sunlight
- If something receives sunlight, it will increase in temperature
- Hence, the puddles of water will increase in temperature

- The puddles of water will increase in temperature
- Temperature is a measure of heat energy
- Hence, the puddles of water will increase in heat energy

- The puddles of water will increase in heat energy
- Evaporation means a substance changes from a liquid into a gas by increasing heat energy
- Water is a kind of substance
- So, the puddles of water will evaporate

Therefore, the puddles of water will evaporate
