puddles of water are outside during the day & if something is outside during the day then that something will receive sunlight ->  puddles of water will receive sunlight  puddles of water will receive sunlight & if something receives sunlight, it will increase in temperature ->  the puddles of water will increase in temperature  the puddles of water will increase in temperature & temperature is a measure of heat energy ->  the puddles of water will increase in heat energy  the puddles of water will increase in heat energy & water is a kind of substance & evaporation means a substance changes from a liquid into a gas by increasing heat energy -> the puddles of water will evaporate
