Evaporation resources

Task: Answer three questions. Assessment focus: condensation.

This task consists of two multiple-choice questions on humidity.

This practical task has students investigate the surface area of three objects and whether this influences the rate of evaporation. Students fill in a table, and calculate the water loss and answer questions to show their understanding.

Task: Describe what happens to water on black plastic and explain why. Assessment focus: effect of colour on heat retention.

Using diagrams of 6 different common situations, students are asked to identify each situation as evaporation, condensation, or neither.

Students evaluate a fair test about whether salt or sugar solution dissolves faster.

Task: Answer questions about what happens to water in open and closed containers. Assessment focus: evaporation.

Task: Describe where water goes when washing is drying and from a swimming pool, and discuss factors that affect this process. Assessment focus: evaporation.

Task: Students draw to show their ideas about what happens when a puddle dries up. Assessment focus: evaporation.

For each of eight provided situations students identify whether each is an example of evaporation, condensation or neither of these.

Task: Complete a diagram of part of the water cycle and answer a question about rain. Assessment focus: Question a) – the water cycle and conventions of diagrams; question b) – evaporation of a solution.

Task: Students make predictions about evaporation rates of instances where surface areas are a factor, select which variable is being investigated in both examples and explain their answer. Assessment focus: Using knowledge of surface area to make predictions.

Task: Answer questions about what happens to water in open and closed containers and compare to the water cycle. Assessment focus: evaporation, the water cycle.

Task: Match the parts of a water cycle to the parts represented in a model of the water cycle and compare how they are the same and different. Assessment focus: interpreting a model.
