Year 11

Using Resources

This lesson will look at the Earth's natural resources and products. We will also look at the difference between finite and renewable resources.

Finite resources

This lesson will look at what life cycle assessments (LCAs) are, how they are carried out and how to analyse their data.

Life cycle assessments

This lesson will look at the importance of reducing waste, reusing products and recycling both in terms of environmental impact and ensuring materials for the future.

The importance of recycling

This lesson will look at alternative methods of extracting copper and why alternative methods are important. We will compare the methods of phytomining and bioleaching.

Phytomining and bioleaching

This lesson will look at corrosion and rusting. We will look at experiments to see what is needed for rusting to occur as well as what we can do to prevent rusting. We will look at the sacrificial protection of iron using zinc.

Rusting

This lesson will look at metals and why they are often alloyed. We will look at common examples of alloys and what they are used for.

Alloys

This lesson will look at the different properties of polymers and their uses. We will look at the differences between high and low density poly(ethene) as well as the differences between thermosetting and thermosoftening polymers.

Polymers

This lesson will look at how glass is made as well as the uses of composites and ceramics. We will compare the physical properties of glass, ceramics and composites, and explain how their properties are related to their uses.

Glass, ceramics and composites

This lesson will look at the difference between pure and potable water. We will look at how water is treated so that it is safe to drink and also we will also look at two methods of desalination.

Safe drinking water

In this lesson we will look at the required practical on potable water. We will recap how to test for pH and calculate the mass of dissolved substances in water from different sources. We will also look at distillation as a method for purifying water.

Required practical on potable water

This lesson will look at why waste water needs to be treated before being returned to the environment. We will look at the stages of sewage treatment. We will compare which method is easiest for obtaining potable water.

Wastewater treatment

This lesson will look at why ammonia is such an important compound. We will look at the Haber Process and the different conditions that are used.

Making ammonia and the Haber Process

This lesson will look at the Haber Process and the need for compromised conditions in the manufacturing process. We will look at the effect of temperature and pressure on the yield of ammonia as well as the importance of a catalyst.

The economics of the Haber Process

This lesson will look at the NPK fertilisers and what they are made of. We will compare the process of making fertiliser in the lab compared to making it in industry.

Making fertilisers in the lab and in industry

This lesson will review the key concepts for this unit. We will recap finite and renewable resources, the importance of LCAs, how potable water can be obtained and the process of wastewater treatment.

Review lesson

This lesson will review the key concepts for this unit. We will recap rusting, alloys, polymers and the Haber process.

Review lesson: Chemistry content

This lesson will look at answering exam questions which have the command words 'compare' and 'evaluate'. We will look at specific examples of these questions with life cycle assessments and the treatment of potable water.

Exam skills: Compare and evaluate

This lesson will look at the role that Kitty Hach Darrow played in the development of water analysis through the Hach company. We will also recap the importance of potable water.
