ExperimentThe effect of concentration and temperature on reaction rate
Reaction rate can be altered by many things, in this practical students explore how temperature and concentration effect reaction in an closer look at kinetics. Includes kit list and safety instructions.
-
ExperimentReacting elements with oxygen
Different members of the periodic table will exhibit different reactions when exposed to oxygen, often through heating. This practical supports students to understand the diversity of chemicals and their principles.
-
ExperimentCreating an effervescent universal indicator ‘rainbow’
This quick practical uses existing chemicals in your learning space, for students to observe the effervescent reaction that causes universal indicator to create a ‘rainbow’ of colour. Kit list and safety instructions included.
-
ExperimentThe reaction of magnesium with steam
Plunge a burning magnesium ribbon into the steam above boiling water and allow the hydrogen that is formed to burn – or collect it over water and test it with a lighted spill.
-
ExperimentMaking a reaction tube
Guide students through this practical to create a reaction tube. Includes kit list and safety instructions.
-
ExperimentProperties of the transition metals and their compounds
Student discover the diversity of transition metals in this practical that puts their knowledge of these common elements to the test. Includes kit list and safety instructions.
-
ExperimentDisappearing ink
Explore the reaction between acids and bases as students create disappearing ink, in this favourite classroom practical.
-
ExperimentTesting 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.
-
ExperimentRubber 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.
