Body Systems Detective KS3 is a five-mission Year 8 science activity book mapped to the DfE National Curriculum for KS3 biology: body systems. Pupils investigate the functions of the skeleton (support, protection, movement and making blood cells), work out how muscles pull in antagonistic pairs such as the biceps and triceps, identify hinge and ball-and-socket joints, put the digestive system in order and meet the enzymes that break down food, follow oxygen and carbon dioxide through the lungs, trachea, diaphragm and alveoli, and plan a balanced diet from its food groups. 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.
