Sound Detective KS2

Sound Detective KS2 is a five-mission Year 4 science activity book mapped to the DfE National Curriculum unit on sound. Children discover that sounds are made when objects vibrate, that vibrations travel through a solid, liquid or gas medium to the ear drum and cannot travel through a vacuum, how pitch depends on how fast an object vibrates and on its length, tightness and thickness, and how volume depends on the size (amplitude) of the vibration and fades with distance, finishing with a muffling investigation and a fair-test task. 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.
