Today, the children were involved in an evaporation experiment. Year 4’s task was to wet towels and to predict which towel evaporated the quickest. Firstly, the children discussed how they would make the test fair – by making sure we had the same sized towels for each group, we poured the same amount of liquid on each towel to make them wet, we measured the temperature in each location the towels were placed in (Mr Dixon’s office, the classroom and outside) and made sure each towel had the same amount of time to dry. The children found that the towel that was left outside evaporated the quickest compared to the towel left in the classroom and the office. We understood that evaporation is when a liquid changes into a gas – which is handy when we need to dry our clothes. Well done, Year 4!
