Resource
Changing the properties of polymers and plastics

Learners consider how changes to polymers, for example adding plasticisers or cross-linking, affects the properties of the objects made from the polymers.
Resource
Polylactic acid

Explore an example of condensation polymerisation with this practical activity where lactic acid is reacted to make short strands of polylactic acid.
Resource
Textile conservation

Explore textile conservation as a context for practising organic and polymer chemistry.
Resource
Baking powder

Explore the chemical properties of baking powder and understand how why it is added during baking and cooking.
Resource
Investigating a natural composite | chicken bone

Two chicken bones are the basis for this exploration into natural composites, where learners understand how each component affects the bone itself.
Resource
Making new medicines | combinatorial chemistry

How do pharmacists create new medicines, and what role does the pharmaceutical industry play in chemical research? Find out with this resource.
Resource
A composite material: concrete

As a composite material, concrete requires a balance of ingredients to be effective. Investigate how different additives affect the properties of concrete.
Resource
Changing the surface

Explore how the characteristics of fabrics can be changed by the addition of a polymer to its surface.
Resource
Nanosilver in medicine

Silver is known as a precious metal that is prized for jewellery, however it has medicinal properties that learners can explore with this resource.
Resource
Nanotechnology size and scale

Investigate size and scale by comparing a set of objects and choosing which best represents a unit of measurement.
Resource
Nanotechnology and smelly socks

Take a closer look at fabric fibres and the effect of bacteria decay. How does this contribute to smelly socks and what can nanotech do to help?
Resource
Plastics

Introduce learners to plastics, how they are used, and what the advantages or disadvantages of using them are.
Resource
The surfaces of substances

Understand how materials change between their surface behaviour and their bulk behaviour with this resource.
Resource
Superconductors

Investigate superconductors and their properties, including the structure and bonding of metals, and giant ionic compounds.
Resource
Active and intelligent packaging

Support learners to understand intelligent packaging, polymers, and micro-organisms with this exploration into the function of food packaging.
Resource
Dry cleaning and green Chemistry

Dry cleaners often use perchloroethene instead of water - how do these methods differ and what are their advantages?
Resource
Nappy choice and the environment

How are nappies made, used and disposed of - this is the topic open to learners who use this resource.
Resource
Disposable cups and the environment

Learners investigate which material is for disposable cups, polystyrene or paper?
Resource
Feed the world: artificial nitrogen fertilisers

Should we be using artifical fetalisers? That’s th question that students can research and debate in this resource.
Resource
Green Chemistry, atom economy and sustainable development

How can learners use chemistry to contribute to a greener world? What role does pollution play in the chemical sciences?
