No Prep Plans: Year 8 Biology – Joints & Muscles
Research + Group Project: Build a Working Model of a Joint

Help your students discover how the human body moves with this engaging, hands-on Year 8 Biology lesson! Students investigate the structure and function of joints, muscles, tendons, and ligaments before designing and carrying out their own movement investigation and building a working model of a human joint.

Part of the No Prep Plans: Year 8 Biology series, this resource is designed to promote inquiry-based learning, collaboration, and scientific thinking while helping students make meaningful connections between biology and the real world.
