Communicate, with clarity and correctness, using the appropriate language, the biomechanical concepts and principles related to balance, stability, spin, and rotation.

Explore and describe the impact of variations of base of support (e.g., narrow, wide) and location of centre of gravity (e.g., low, high, above base of support, outside of base of support) on balance.

Propose solutions for improving balance related to given situations (e.g., a person who tries to do a headstand always tips over).

Explain how equipment required for participation (e.g., heavy backpack, snowshoes) and for protection (e.g., helmet and padding) might affect balance.

Explain why balance is challenged when participating in various movement activities (e.g., skating, paddling a canoe, walking on a balance beam, walking on stilts).

Analyze how one's balance will be affected by body type (e.g., very tall versus short, very tall and light weight versus very tall and heavier weight).

Explore and describe the flight of an object using a variety of ways to contact the object (e.g., punt a football using the side of the foot, using the top of the foot; contacting the ball crosswise, contacting the ball lengthwise; serve a volleyball underhand using a fist, using an open hand; contacting the ball underneath, in the center, on the right side, on the left side).

Explore and explain how rebound is affected when different spins are applied to an object (e.g., top spin versus backspin applied to a basketball when doing a bounce pass).

Propose solutions for improved direction of flight related to given situations (e.g., a volleyball serve is always veering off to the left).

Explore and explain how moving the mass of an object closer to the axis of rotation will cause the object to rotate faster.

Describe ways to increase and decrease the momentum of a spin (e.g., move arms closer and farther away from the body).

Explore and describe how velocity of rotation can be increased when participating in movement activities (e.g., throw a ball sidearm while standing, then throw a ball sidearm after rotating in a complete circle).

Consider and explore the application of the biomechanical concepts and principles of balance, stability, spin, and rotation to enhance movement as required by the flow of play in striking/fielding games, net/wall games, and low-organizational and inventive games.

Consider and explore the biomechanical concepts and principles of balance, stability, spin, and rotation to enhance movement used in alternate environment and body management activities.
