Unit Summary
This unit explores the role of skeletons and muscles in humans and other animals for support, protection, and movement. It involves setting up practical enquiries, making observations, measuring accurately, recording findings, and using results to draw conclusions and suggest improvements.
Lesson Summary
You will learn to explain why humans have muscles.
Key Notes
- Humans and most other animals have muscles throughout their bodies that help them to move and balance
- Different muscles move different parts of the body
- Muscles work in pairs around our joints to help us move
- One muscle pulls in one direction, and another pulls in the opposite direction
Vocabulary To Learn
- muscle: A muscle is a part of the body that pulls on bones to help us move.
- movement: Movement is when a person, animal, or object changes position.
- direction: Direction is the path taken by someone or something to reach a particular place.
- joint: A joint is the place where two bones meet.
Common Mistakes To Avoid
- Pupils may think that there is just one huge muscle that moves the body.
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key points.
Humans and most other animals have muscles throughout their bodies that help them to move and balance. Different muscles move different parts of the body.
2. Define this scientific word and use it in context. 'muscle'
A muscle is a part of the body that pulls on bones to help us move. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: Pupils may think that there is just one huge muscle that moves the body. Correction: Use diagrams that explain how muscles work in pairs and that muscles are different sizes throughout the body.
