Begin the lesson by introducing the concept of muscles and their role in movement. Use engaging questions to hook students' interest, such as 'What makes you move?' or 'How does your heart keep beating?'

Explain the muscular system and its importance in daily activities. Discuss how muscles work with bones to enable movement and how the heart functions as a muscle.

Use the video 'All About Your Body' to visually demonstrate how the muscular system functions alongside other body systems. This video provides a foundational understanding of human anatomy and physiology.

Engage students in a discussion about how muscles grow stronger through use and a healthy diet. Encourage them to share examples of activities they do that help strengthen their muscles.

Have students participate in a simple exercise routine to feel their muscles at work. Ask them to identify which muscles they are using during each activity.

Assign the 'What’s Inside Your Body?' assessment where students label a diagram of the human body, reinforcing their understanding of muscle locations and functions.

Conduct a quick quiz to assess students' understanding of the muscular system and its functions. Use questions that require them to identify muscles and their roles.

Encourage students to reflect on what they have learned about muscles and their importance. Ask them to write a short paragraph about how they can keep their muscles healthy.

Use the 'What’s Your Pulse Rate?' assessment to explore how exercise affects heart rate. This hands-on activity helps students understand the relationship between physical activity and heart health.

For further exploration, students can complete the 'Review – Healthy Body' assessment to reinforce their understanding of healthy lifestyle choices.
