Explore the reaction between acids and bases as students create disappearing ink, in this favourite classroom practical.
-
Experiment
Testing salts for anions and cations
A full range of chemicals will guide students into discovering how to identify the composition of unknown substances. Includes kit list and safry instructions.
-
Experiment
Rubber band experiment
A rubber band, a hairdryer, and a curious mind will see students discover the principles of heat based reactions. Includes kit list and safety instruction.
-
Experiment
Chemistry and electricity
Create coloured writing from acids, alkali, and salt solution, all activated through electrolysis.
-
Experiment
A Cartesian diver
An old favourite experiment, the Cartesian diver is easy for students to complete. Explore important ideas that build a foundation of knowledge.
-
Experiment
Viscosity
Compare the viscosity of thick and thin liquids in this experiment, which gets young learners exploring how viscosity alters the speed of an air bubble through the substances. Includes kit list and safety instructions.
-
Experiment
The 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.
-
Experiment
Burning milk powder
Gather a Bunsen burner, and some common powdered milk to help students grasp the ideas of surface area and reaction rates. Includes kit list and safety instructions.
-
Experiment
A visible activated complex
A simple demonstration of catalysis also introducing the idea of an activated complex and to allow discussion of the mechanism of catalysis. Includes kit list and safety instructions.
-
Experiment
Hydrogen peroxide decomposition using different catalysts
Collect a range of catalysts to explore the decomposition of hydrogen peroxide, paying close attention to the varied reaction rates. Includes kit list and safety instructions.
-
Experiment
Competition for oxygen | reacting metals with oxides
Explore the reactions of metals when exposed to the oxide of another metal. When reactions like these occur, the two metals compete for the oxygen. Includes kit list and safety instructions.
-
Experiment

Ignite methane with oxygen in a bottle, and amaze students with this methane rocket. Contains kit list and safety instructions.
-
Experiment
Extracting limonene from oranges
Limonene is found in oranges, and now your classroom. Create a distillation apparatus and support students to make their own plant oils. Includes kit list and safety instructions.
-
Experiment
The effect of concentration on reaction rate
Students react sodium thiosulfate solution is reacted with acid – a sulfur precipitate forms. The time taken for a certain amount of sulfur to form can be used to indicate the rate of the reaction. Contains kit list and safety instructions.
-
Experiment
Diffusion 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.
