chemically combining small molecules called monomers to form long chain structures called polymers

Polymer properties and processes

Design and technology

Pupils will analyse products to identify features in the products.  They will also identify the materials, material properties and manufacturing processes used to create the products.  They will   conduct functional tests to collect and analyse data to inform design decisions.

Product analysis: encouraging healthy lifestyles

Physical activity and equipment requiring safe use

Use of equipment that may require supervision for safety, e.g. scissors in KS1, needles, paint, knives, cooking.

The advantages of injection moulding are:

Polymers can be categorised as __________.

Polymer products are often stamped with this symbol, why?

They can cause pollution on land and oceans.

Animals can get stuck in or try to eat them.

Why are single use polymers like drinking straws discouraged?

It does not conduct heat, so it's safe to hold.
