Chlorophyll fluorescence

From Solar Spark, this activity allows students to see how chlorophyll can be energised and how this causes it to fluoresce. Chlorophyll in plant leaves absorb red light and pass the energy on to other parts of the plant, hence leaves look green. But if there is nowhere for the energy to go, it gets released as...

A Hydrogen-oxygen Fuel Cell

In this classic demonstration, from the Royal Society of Chemistry, two methods of making a hydrogen oxygen fuel cell are described. One involves the use of platinum electrodes and the other uses carbon electrodes. Each cell has a potential difference of around 1 Volt. The resource provides a list of apparatus and...

Gold award: investigate the properties of materials used for saucepans

Students investigate the properties of materials used for cooking utensils in order to collect quantitative data.  For example, if testing for thermal conductivity they should gain a value for the rate at which heat flows through a cross-sectional area of material.  Students should also find out if there are any...

Clock reaction

Two translucent liquids are mixed. At first, nothing happens: the resulting solution is still translucent. Suddenly, with no warning, the solution turns blue-black all at once.

Curriculum links include redox reactions, rate of reaction, kinetics

Modelling Climate Change

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP) and produced in partnership with the Walker Institute for Climate System Research. Climate scientists do not have a ‘climate in a test tube’ to try out their ideas, so to understand the...

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...

Electrical Installation

Produced for Future Morph, these resources contain a video in which a student talks about her apprenticeship course in electrical installation at Exeter college. She describes the entry qualifications needed for her course, contrasts her experiences at college compared to school and briefly...

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...

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...
