(16 periods)
A force is a push or pull. When force is applied to an object, it acts on the object by changing shape, direction and or movement. The movement of an object depends on the size of the force acting on it. The greater the force, the greater the speed of the object. Levers are machines which magnify a force or a movement. Friction is a force that opposes motion.

4.4.1 recognize and give examples of different types of forces (k)
|
4.4.1.1 identify three different types of forces that indicate changes in shape, movement and stopping
|
|
|
4.4.2 recognize that when things change in shape, begin to move or stop, or change direction, forces are acting on them (k)
|
4.4.2.1 describe the movement of an object in terms of size and direction of the force acting on it
|
|
|
4.4.3 understand that the movement of an object depends on the size and direction of the forces acting on it (by using simple elastic and wind powered devices) (u)
|
4.4.3.1 compare and contrast the different speeds of three moving objects; contrast the forces required to stop them
|
|
|
4.4.4 recognize that the greater the speed of an object, the greater the force and time taken to stop it (k)
|
4.4.4.1 state that a heavy object exerts a greater force than a light object when both move at the same speed
|
|
|
4.4.5 know that vehicles moving on a road or boats moving in water need time to slow down and stop (k)
|
4.4.5.1 demonstrate in a practical way, that a moving toy truck need time to slow down and stop
