About this worksheet
Particle diagrams open this Year 4 science end-of-topic test, which has 30 questions in four sections over 14 pages and is planned for 30 to 45 minutes. Pupils name the diagrams, decide whether sand is a solid, read a thermometer showing 24 °C and use a melting-point table for ice, butter, candle wax and aluminium. Later sections cover a sock-drying investigation at 12, 20 and 30 °C, condensation on Priya's cold bottle and the water cycle. The test follows the Year 4 States of matter programme in the England National Curriculum. Three answer pages give every response, including the mass each sock lost.
