Irreversible changes: That’s Chemistry!

In association with ABPI

The ‘irreversible changes- chemical reactions’ chapter from That’s Chemistry! This chapter looks at key ideas and activities that can be used to help students learn how non-reversible changes result in the formation of new materials.
Resource
Mixing and dissolving materials: That’s Chemistry!

In association with ABPI

The ‘mixing and dissolving materials’ chapter from That’s Chemistry! This chapter looks at key ideas and activities that can be used to help students learn that mixtures are made up of more than one substance and that some mixtures can be separated.
Resource
Heating and cooling materials: That’s Chemistry!

In association with ABPI

The ‘heating and cooling materials’ chapter from That’s Chemistry! This chapter looks at key ideas and activities that can be used to help students learn how the properties of some materials change when they are heated, and that some of these changes are irreversible.

Resource
Burning: That’s Chemistry!

In association with ABPI

The ‘burning’ chapter from That’s Chemistry! This chapter looks at key ideas and activities that can be used to help students learn that when materials are burned new materials are formed, and that this process in not reversible.
Class experiment

Science festivals

This set of handouts can be used to inspire people of all ages to take up chemistry in their own home! Racing raisins, cornflour gloop, erupting volcanoes, reaction times and iron from breakfast cereal are all covered here
Resource
Modelling sedimentary rocks

Students use syringes to make samples of sedimentary rock from sand both with and without cementing agents.
Resource
Weathering and erosion

Examine the ways in which water can weather rocks, by solution and by freeze-thaw.
Resource
Hand warmers

Use these student activities and teacher guide to investigate reusable and disposable hand warmers. You will compare reusable variants made with sodium acetate vs disposable handwarmers. You can also try making your own hand warmers. These activities may work well as a project on class topics like ‘winter’ or ‘body ...
Resource
Limestone weathering

This activity is designed for students aged 11-14. It can be used to reinforce work on the reactions of carbonates with acids as well as the chemical weathering of rock.
Resource
Making a volcano

Simulate ways in which both extrusive and intrusive igneous rocks may form
Class experiment
Colour chemistry

A variety of experiments that explore colour changing, so learners can experience a comprehensive look into the brighter side of chemistry
Resource
Wood conservation - the Mary Rose

The Mary Rose is a wooden Tudor warship that sank off Portsmouth in 1545. While on the sea bed, most of her hull became covered in silt, which effectively sealed it and the artefacts it contained in anaerobic (air-free) conditions and preserved them from decay.
Resource
Gravestones

Investigation into the weathering of different types of rock.
