(1) When a liquid evaporates it becomes a gas

(2) Know how to measure the volume of water accurately

(3) Know how to relate patterns in results to scientific knowledge

(4) Everyday appliances can speed up evaporation

(5) Condensation is when a gas turns into a liquid

(6) Condensation is the reverse of evaporation. Water vapour in the air may condense when it meets a cold surface

(7) When a liquid boils it turns into a gas. Water boils at 100°

(8) Materials can be in one of three states - solid, liquid, or gas

(9) The water cycle is when water evaporates from lakes and oceans [and other waterways - Abiator], condenses into clouds, and eventually falls as rain or snow

Learning Objectives (Skills): Changing State

(1) Offer own ideas for scientific enquiry. Set up fair test for measuring volume, selecting a suitable way to present evidence. Relate pattern in results to scientific knowledge

(2) Make careful observations

(3) Make a prediction and decide whether the evidence supports it. Use results to test out a prediction.

(4) Measure temperature. Draw a line graph. Use results to test out a prediction
