Evaporation and condensation

Children begin to learn about the water cycle and begin to understand the terms evaporation and condensation.

Science Objectives
i) Identify the part played by evaporation and condensation in the water cycle and associate the rate of evaporation with temperature.

ii) Observe that some materials change state when they are heated or cooled, and measure or research the temperature at which this happens in degrees Celsius (°C).

Working Scientifically

1. Ask relevant questions and use different types of scientific enquiries.
2. Set up simple practical enquiries and comparative and fair tests.
3. Make systematic and careful observations and, where appropriate, take accurate measurements using standard units, using a range of equipment, including thermometers and data loggers.
4. Record findings using simple scientific language, drawings, labelled diagrams, keys, bar charts and tables.
5. Report on findings from enquiries, including oral and written explanations, displays or presentations of results and conclusions.
6. Use straightforward scientific evidence to answer questions or to support findings.
