Chemical garden

The chemical garden is a well‐established experiment from the chemistry of salts, solubility, diffusion, and solutions. The nice thing is that if metal salts are put in sodium water glass solution, it can lead to an effect reminiscent of plants growing. This growing process can be observed and analysed. In the end...

Chameleon bubbles

Chameleon bubbles are formed when a sodium alginate solution is dropped into a calcium chloride solution.  The bubbles are filled by an acid‐base indicator solution; so, adding the beads to acids or bases leads to colour changes inside the bubbles by diffusion and pH change. Students can learn about acids, bases,...

Cracking Hydrocarbons

In this classic experiment, from the Royal Society of Chemistry, students heat a large molecule with a catalyst and collect the gas produced. The gas produced is tested with bromine water for the presence of a double bond. The resource is set out as teachers' notes followed by the students' page which presents the...

Calculations with hundreds and thousands

This resource, from the Centre for Innovation in Mathematics Teaching, builds on students' previous knowledge of multiplying by powers of 10 to demonstrate how calculations such as 2000 x 300 can be performed accurately. Follow-up exercises provide practice in the skills learned.

Electrical and Electronic Engineering

Produced for Future Morph, this resource includes a video in which a student talks about his course in electrical and electronic engineering. He describes how one project was to make and test a circuit that included a light-sensitive resistor. A second activity describes a class experiment...

Mystery of Gibraltar

Students learn about the solutions of a particular substance which...

Red or blue flowers?

Students investigate transport in plants by seeing what happens when flowers are placed in different coloured solutions.

Leaking bag

This mystery can be used to introduce osmosis and diffusion. 

Two beakers are displayed at the front of the room. Both look identical in that they both contain a plastic zip--lock bag with a starch solution inside. The zip-lock bags are both sitting in a clear solution. What the students don’t know is that...

Eating nails

In this investigation, students extract iron from a breakfast cereal and consider how our bodies are able to digest iron by looking at its reactions with hydrochloric acid.

Gelli baff

Gelli Baff, a crystalline powder, has been dumped into a bathtub filled with water. How can you force the hydrogel to go down the plughole in order to drain the bathtub? 

In this investigation, students learn about swelling reactions, balanced reactions, and polymerisation. Students should be able to...
