Muscles and Bones: Movement Foundations

Understanding the musculoskeletal system Year 9 Physical Education Building blocks of human movement

What We're Learning Today

Identify major muscle groups and their functions Understand how muscles work in pairs Explore bone structure and protection roles Apply knowledge through hands-on activities Connect to injury prevention in sports

Major Muscle Groups

Muscle Pair Investigation

Partner up with someone nearby Take turns flexing and relaxing your biceps and triceps Feel how one muscle contracts while the other relaxes Try this with other muscle pairs around your body Record your observations on the worksheet

Muscles vs Bones: Different Jobs, Same Team

{"left":"Muscles create movement through contraction\nBones provide structure and support\nMuscles are soft tissue that can stretch\nBones are hard tissue that protects organs","right":"Muscles need energy from food to work\nBones store minerals like calcium\nMuscles can repair quickly when injured\nBones take longer to heal but are very strong"}

How Bones Support Movement

Provide attachment points for muscles Act as levers to amplify muscle force Protect vital organs during activity Store minerals needed for muscle function Create joints that allow flexible movement

Think and Discuss

What would happen if we only had muscles but no bones? What would happen if we only had bones but no muscles? Why do you think muscle and bone injuries are treated differently?

Keeping Your Musculoskeletal System Healthy

Regular exercise strengthens both muscles and bones Proper nutrition provides calcium and protein Adequate rest allows repair and growth Proper warm-up prevents injuries Good technique in sports protects joints Stay hydrated during physical activity
