States of Matter Detective KS2

States of Matter Detective KS2 is a five-mission Year 4 science activity book mapped to the DfE National Curriculum for states of matter. Children compare and group materials as solids, liquids and gases by their properties, observe and name the changes of state (melting, freezing, evaporation and condensation) caused by heating and cooling, measure temperature in degrees Celsius knowing water freezes at 0°C and boils at 100°C, and identify the part played by evaporation, condensation, precipitation and collection in the water cycle. Every question is auto-marked on screen, or the whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
