The National Curriculum for Science says:

A high-quality science education provides the foundations for understanding the world
through the specific disciplines of biology, chemistry and physics. Science has changed
our lives and is vital to the world’s future prosperity, and all pupils should be taught
essential aspects of the knowledge, methods, processes and uses of science. Through
building up a body of key foundational knowledge and concepts, pupils should be
encouraged to recognise the power of rational explanation and develop a sense of
excitement and curiosity about natural phenomena. They should be encouraged to
understand how science can be used to explain what is occurring, predict how things will
behave, and analyse causes.
