- - - - B. Fact: a table is a normal force
        
        C. Example: A table stops a plate from hitting the floor.
  - - - B. fact: if you push a door it will open
        
        C. Example: Pushing a balloon under water in a bucket causes the water to rise.
        
        D. picture
        
        e. observations: the distance that a ball will go when it is hit relies on how hard you hit the ball and the weight of the ball. push can be a non contact force if something is pushed by wind.
  - - - B. fact: Static electricity is caused by friction
        
        C. Example: if you rub a balloon on a cloth the put it over your hair, friction and static electricity will cause your hair to rise toward the balloon.
        
        D. picture
  - - - B. fact: pull is the opposite to push
        
        C. Example: if you pull someone they will move toward you !
        
        D. Picture
        
        e. observations: pull can be a non contact force if it pulled by mass such as magnets and a push force can be converted to a pull force.
  - - - B. fact: sometimes if you twist a lid of a jar the lid will come off.
        
        C.example: if you twist a lock in the correct direction what ever the lock is on will unlock.
        
        D. picture
        
        e. observations: twist is a force that can be converted from a push force and is used in mechanical systems such as taps that have twisting tops.
- - - - B. fact: An electromagnet is created by coiling a conductive wire around a core made out of materials like iron, nickel or cobalt. These materials are used because they are easy to magnetize. Flowing electricity produces a magnetic field that encloses the wire carrying the electric surge.
        
        C. Example: Motors and generators are types of electromagnets
  - - - B. Fact: Gravity is what makes the planets orbit the sun.
        
        C. example: if you throw a ball in the air and it falls back to the ground that is gravity acting.
        
        E. observations: planets and stars need gravity to move and the closer they are to the sun the faster they go and the closer to the sun they are the more circular their orbit is.
  - - - B. fact: magnets use magnetism between the two poles which are the north and south poles.
        
        C. example: a compass uses magnetism to determine which direction you are going in by using the magnetism from the earth's core because the earth's core is magnetic. motors fro things such as : cars and lawnmowers also use magnetism to work.
