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.

Biopolymers for Cancer

What do seaweed and innovative cancer prevention drugs have in common? Alginates of course! This experiment looks at biopolymers; their structure, how they can be used and how we make them.

Cages to trap metals

The need to safely manage and dispose of waste becomes more and more important, as we are facing an increase in our dependency on nuclear fuel. What role do zeolites play, and how can we observe ion exchange?

Carbon for water treatment

Providing clean water for people to drink is one of the biggest challenges facing our world. What materials can we use to remove pollutants?

Corrosion Art

Hands-on experiment, looking at the corrosion of copper and steal and the electrochemical processes at play.

DNA barcodes for healthcare

DNA (deoxyribonucleic acid) is present in the living cells of animals and plants, and contains the genetic code that determines the make-up of every single protein of an organism. In this experiment, we extract the DNA from cells of strawberries and bananas.

Sensing with fluorescence

Create your own fluorescent pH sensor, while developing filtration and extraction practical skills.
