ExperimentThe oxidation states of vanadium
Introduce your students to the idea that different oxidation states of transition metal ions often have different colours, and that electrode potentials can be used to predict the course of the redox reactions. Includes kit list and safety instructions.
-
ExperimentDiffusion of gases – a safer alternative to bromine
Diffusing gases can be a tricky thing to do, but by creating an alternative to bromine, you can make a safer classroom alternative for this process. Kit list and safety instructions included.

ResourceUse the particle model of matter
How well does the simple particle model of matter explain observations of changes of state?
-
ResourceChemistry and Sport - diving
Gravity - the enemy of the high-jumper, and the diver’s friend. Find out how the sport of diving relies on gravity, and why a diver seems lighter in water than on land.
-
ResourceOn This Day - Nov 23 : Henry Moseley was born
He developed a law concerning the characteristic X-rays that are emitted by atoms, and thus allowed atomic numbers to be defined. Until this point, these numbers in the periodic table were simply an element’s place, rather than being associated with a physical property.

ResourceChemical misconceptions II: Mass and dissolving
This exercise is primarily aimed at the 11–14 age range, to discover more about dissolving solids in liquids.
-
ResourceChemical misconceptions II: Changes in chemistry
Explore chemical and physical change in chemistry, explain what each mean, and classify examples of these changes.
-
ResourceChemical misconceptions I: Chemical axioms
Explore the key ideas into how learners respond to the fundamental principles used in chemistry.
-
ExperimentExperiments with particles
Explore physical states, and how material interact with three practicals. Students use common classroom items to explore, and then note their findings. Includes kit list and safety instructions.

ResourceOn This Day - Jan 25 : Robert Boyle was born
He famously discovered that the volume of a gas is inversely proportional to its pressure (Boyle’s Law) and, together with Robert Hooke, invented the vacuum chamber. Boyle was also a founding member of the Royal Society.
-
ResourceThe ten gram boat race
Explore surface tension in this experiment that gives learners a practical way to test out their chemical concepts. Includes kit list and safety instructions.

ResourceInsulation and conduction: That’s Chemistry!
The ‘Insulation and conduction’ chapter from That’s Chemistry!: This chapter looks at key ideas and activities that can be used to help students learn how materials have different properties, including whether they are conductors or insulators of heat and/or electricity.
-
ResourceHeating and cooling materials: That’s Chemistry!
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.
