    In this recorded professional learning session, Greta Dromgool and Ted Cizadlo will build your confidence to teach the Physical World. The New Zealand Curriculum achievement objectives for this area are incredibly broad, and gravity is a lot weirder than we think! Using simple examples, we will take you step by step through how you can teach this concept and unpack students’ alternative conceptions.

    LOVED the webinar on gravity – just awesome – thanks so much especially the practical easy experiments for us to do in class.

    Nature of science

    In science, a model is a representation of an idea, an object or even a process or a system that is used to describe and explain phenomena that cannot be experienced directly. Models are central to what scientists do, both in their research as well as when communicating their explanations. Learn more about models in science in the article Scientific modelling.
