KS3 (Age 11-14)

Key stage 3 science is all about exploring how science can be used to explain what is occurring, predict how things will behave, and analyse causes. Developing robust skills to allow scientific enquiries to be conducted are important to learn how to work objectively, modifying explanations to take account of new evidence and ideas.

Pupils should begin to see the connections between subjects that are taught across all three sciences, and become aware of some of the big ideas underpinning scientific knowledge.

Here is a list of our experiments and activities for students in Key Stage 3:

Slide4Reactivity series of metals, using materials,  and corrosion




Slide5Synthetic and naturally occurring polymers




Slide5Synthetic and naturally occurring polymers




Slide3The earth’s water resources




Slide9The earth’s water resources




Slide1Filtration methods, extractions, making a pH sensor





Slide3 States of matter, gases
