- 1P.1
  - Lesson 01 - What is a Force? Lesson Plan Lesson Title
    - T: Forces can be either pushes or pulls, which can be combined to form a twist. - KS3.P.15
    - W: Force arrows in free body diagrams are used to show the direction of forces and the size of the force by its length or label.
      
      Force arrows have a solid arrow head. - KS3.P.16
    - T: Forces are measured in newtons with the symbol 'N'. - KS3.P.19
    - T: A newton is the weight of a small apple. - KS3.P.19
    - W: Forces can be combined to help or cancel each other. - KS3.P.16
      - Suggested Activity:
        Role play combining forces with Force arrow props.
        Equipment Required:
        Large (Force) Arrows on metre rules.
    - T: Adding forces in 1 dimension, allows to calculate whether forces are balanced or unbalanced.
      
      Forces in the a backwards direction are considered negative.
      
      The combined force is is called the 'Resultant force' and is the result of adding all the forces together. - KS3.P.16
  - Lesson 02 - What is Momentum? Lesson Plan Lesson Title
    - T: Momentum is the tendency for an object to keep moving as it was. - KS3.P.27
      - Suggested Activity:
        Table cloth trick with beaker of water
        Equipment Required:
        A5ish Scrap paper
        Plastic beakers
    - T: It takes a force to change the momentum of an object. - KS3.P.27
    - T: Changing the momentum of an object could be by changing its speed or its direction. - KS3.P.27
    - W: Unbalanced forces are needed to cause objects to:
      - stop or start moving,
      - change their speed,
      - direction of motion
      These are all forms of acceleration (qualitative only). - KS3.P.27
    - W: The acceleration is in the direction of resultant force and the speed of the change is dependent on the size of the force. - KS3.P.28
  - Lesson 03 - What is Friction? Lesson Plan Lesson Title
    - T: Rubbing causes friction between surfaces. - KS3.P.18
    - W: The amount of friction depends on the roughness of the surfaces (and closing force). - KS3.P.18
      - Suggested Activity:
        Different grit sandpaper Blu-tacked to planks.
        
        Raise one end of the plank until a 100g mass on the sandpaper starts to slide.
        
        Measure the height of the end of the ramp (or angle) analogous to magnitude of friction.
        
        Repeat with 1kg mass to show closing force
        Equipment Required:
        Planks
        5 different grits of sand paper, blu-tack
        100g masses
        1Kg masses
        Meter rules
    - T: Friction always acts to resist motion and therefore acts in the opposite direction to the (potential) motion. - KS3.P.18
  - Lesson 04 - What happens when two forces interact? Lesson Plan Lesson Title
    - W: When an object applies a force to a second object, the second object applies and force equal in size but opposite in direction back. - KS3.P.15
    - T: The force an object applies back is called the Reaction force. - KS3.P.15
    - T: Unbalanced forces can also change the shape of an object: deformation. - KS3.P.18
    - T: When solid objects are stretched there is a force of tension created with in it. - KS3.P.18
    - W: A spring will deform (stretch or compress) until the tension balances the load placed upon it. - KS3.P.26
      - Suggested Activity:
        Student use Newton Meters to weigh objects in the room
        Equipment Required:
        Newton Meters
        selection of items to weigh
    - W: When an object floats there is a force of upthrust. - KS3.P.26
      - Suggested Activity:
        Look at the Hamble science logo - What forces are acting on the boat?
    - W: When an a fluid flows over a wing (aerofoil) it generates lift. - KS3.P.26

  - Lesson 05 - Planning: Hooke's Law Lesson Plan Lesson Title
    - Hooke's law enquiry - PLANNING:
      - Aim: To find out how the length of a spring is affected by load exerted on it.
      - Hypothesis: That the length of a spring is directly proportional to load.
      
      NB: Hypothesis is to be proved false as extension is proportional to load rather than length. Students learn that directly proportional is shown on a graph as linear line through origin. - KS3.P.19
  - Lesson 06 - Data Collection: Hooke's Law Lesson Plan Lesson Title
    - Hooke's law enquiry - DATA COLLECTION:
      - Aim: To find out how the length of a spring is affected by load exerted on it.
      - Hypothesis: That the length of a spring is directly proportional to load.
      
      NB: Hypothesis is to be proved false as extension is proportional to load rather than length. Students learn that directly proportional is shown on a graph as linear line through origin. - KS3.P.19
  - Lesson 07 - Analysis: Hooke's Law Lesson Plan Lesson Title
    - Hooke's law enquiry - ANALYSIS & EVALUATION:
      - Aim: To find out how the length of a spring is affected by load exerted on it.
      - Hypothesis: That the length of a spring is directly proportional to load.
      
      NB: Hypothesis is to be proved false as extension is proportional to load rather than length. Students learn that directly proportional is shown on a graph as linear line through origin. - KS3.P.19

- 1P.4
  - Lesson 09 - How are Forces classified? Lesson Plan Lesson Title
    - T: Forces can also be classified as either:
      - non-contact forces:
      - gravity forces acting at a distance on Earth and in space,
      - forces between magnets,
      - Electrostatic forces due to static electricity: Rubbed balloon - KS3.P.22
      - Suggested Activity:
        Students experience non contact forces with the magnets
        Equipment Required:
        class set magnets
        Balloon
        Duster and Rod (Statics tray)
    - T: Pushing things out of the way also creates a type of friction:
      - ball pit balls
      - air (particles): air resistance
      - water (particles): water resistance
      These forces are also called drag. - KS3.P.18
      - Suggested Activity:
        DEMO: Dropping flat paper and screwed up paper. Which accelerates fastest? Which has the greatest resultant force? But they have the same weight.
        
        DEMO: Dropping Plasticine ball in water and paste
        Equipment Required:
        DEMO: two large measuring cylinders one filled with water, one with wallpaper paste. two balls of Plasticine
        (same size)
  - Lesson 10 - Why do cars have a top speed? Lesson Plan Lesson Title
    - W: Cars have a top speed because:
      - As they get faster they hit more air particles (harder)
      - When the car hits the particles the particles hit the car causing drag
      - The thrust from the engine force is constant
      - When the drag balances the engine force there is no resultant force
      - So no acceleration
      - So car travels at a constant (top) speed - KS3.P.18
      - Suggested Activity:
        DEMO: Toy car to prompt students to think about its shape and drag
        
        CLASS: Students each have a measuring cylinder and time how long it takes different shapes to fall through wall paper paste
        Equipment Required:
        DEMO: Toy car
        
        CLASS: per group:
        1 x large measuring cylinder filled with wall paper paste. plasticine to make into different shape, 1 timer.
    - W: Engines and motors produce a force called Thrust. - KS3.P.18
