Learning Objectives

To gain knowledge and understanding of the different types of joints in the body, and to learn their structure.

To explain the movement allowed of each joint in the body, giving practical examples of what movement is used during specific actions.

Learning Outcomes

Pass: Describe the different types of joint and the

movements allowed at each (P2)

Merit: Explain how joints move during four different

types of physical activity. (M1)

How this will be evidenced:

P2 Completing and defining key terms on a

joints sheet. Label the picture of a synovial joint.

M1 Explain how at least 2 synovial joints move

during four different actions in sport.

FLEXION – Bending a limb between the bones to reduce the angle at a joint.

EXTENSION – Straightening a limb, increasing the angle at a joint. ABDUCTION – Sideways movement away from the centre of the body

ADDUCTION – Sideways movement towards the centre of the body.

CIRCUMDUCTION – Moving a limb through a circle, a full 360 degrees.

ROTATION – Turning a part on its own axis.

In your pairs/groups – you must now think of a sporting action.

You must act it out – including the range of movement.

You score your points depending on how long it takes the rest of the class to guess: Your sport Your sporting action The joint you are talking about (proper name) The type of movement

You have 3 minutes to plan it! GO!!!
