Produced by Solar Spark, this activity allows students to see a condensation polymerisation reaction in action as the polyamide polymer, Nylon, is produced. This is a condensation polymer made of two parent monomers, a di-amine and a di-acid chloride.

The reaction can be used to illustrate:
*...

This video is the full experiment in real time to investigate the rate of conduction in various metals.

This video demonstrates a convection experiment for GCSE Physics using potassium permanganate in water with a Bunsen burner.

The enzyme lactase is widely used in the dairy industry to convert the naturally occurring disaccharide sugar lactose into glucose and galactose. In this practical students investigate the treatment of milk with lactase. Following treatment they test the glucose content of the converted milk, and compare products...

Comets are considered to be time capsules containing information about the conditions of the early Solar System. In order to understand what comets are, where they come from, and their influence on the evolution of Earth, it is necessary to find out what material they contain. This teacher demonstration and student...

In this activity, students make their own thermometer using a jar and a straw. There is a simple explanation of expansion in liquids and questions for students to answer about the Celsius and Fahrenheit scales.

In this Crest Award accredited project, students monitor levels of atmospheric sulfur dioxide and rainfall acidity in the school grounds.  Suggested investigations include:

•  Investigate various methods of measuring acidities between pH4 and pH7, to decide which method is most accurate.
• Compare...

In this project students will research ways of detecting low concentrations of lead and apply these to test samples from the environment. The objective is to investigate whether lead from petrol still persists at the roadside in order to determine whether there is a lurking legacy of lead.

This project encourages students to make contact with a business that performs quality control analyses, such as a public analyst who tests samples for the Trading Standards Department.  Students will need to carry out both quantitative and qualitative analysis on tablets with a single active ingredient, such as...

In this project, students make their own aspirin or paracetamol and then test the purity of the pain-reliever and compare it to shop-bought.  This covers titrations, chromatography and other analytical techniques.

The aim of this project is to investigate the properties of alcohol/water mixtures, and how these properties can be used to measure alcohol content. The alcohol in drinks is ethanol, C₂H₅OH. However, the ethanol used in the laboratory has been methylated by adding 5% of methanol, CH_3...

This booklet in the Griffin Technical Studies series provides practical activities in which students investigate aspects of forensic science. The resource can be used as part of cross-curricular learning and case studies are provided to encourage logical thought, debate and discussion and decision making skills....

In this activity students investigate the mystery of a light beam which seems to bend.  Students can investigate:

• Qualitative behaviour of light  when the medium in which it propagates changes its refraction index. 
• Quantitative evaluation of the behaviour of light in refraction by means of...

Six groups of practicals produced by the Institute of Physics (IOP) that help students to find out more about how science is applied to using and testing new materials.

In addition to the guidance included for specific activities, please refer to the generic health and safety information before commencing...

Cytology, Genetics and Evolution is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education by John Murray. Each title covered one or two topics and brought together the best of the teaching notes...
