Gravity and wind as forces

    I'm a PGCE student based in year 1 and have a query regarding the teaching of forces. During a
    lesson today on 'wind as a force' with the outcome 'understand that it
    is not just ourselves that move things, the teaching highlighted that my sibject knowledge was incorrect. Previous lessons looked at
    pushes and pulls. The teacher noted that wind is not a force but
    an example of a push force, the next lesson is looking at gravity as a
    force- she has again highlighted that gravity is not a force but an
    example of a pull force and that there are only three forces, push, pull
    and twists.
    I have used the Scholastic 100 lessons book and the Achieving QTS
    standards handbook but none of them refer to only pushes, pulls and
    twists are forces.
    It has been noted that I am lacking
    subject knowledge, but before I teach my next lesson I want to be clear
    that she is right, however even when researching online and from my
    previous knowledge I can see that gravity is a force :-(

    A force is defined as a push or a pull on an object. A twist is really just a combination of a push and pull, but to keep it simple for year 1's a twist is a good enough description.

    Gravity does cause a pull on objects, and it is know as a fundamental force in physics. To say gravity isn't a force isn't true, it's a specific type of force. Magnetism is also a force, as it can exert a push or a pull depending on the other object. The example of wind is frictional forces (air resistance).

    Whilst the teacher may be keeping it simple for year 1, I don't think there's any reason telling them about gravity being a specific force that pulls objects.
