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 video, produced by Teachers TV, Dr Shini Somarathne presents a run-down of the top ten experiments that go wrong for teachers, compiled by school science support service CLEAPSS. Expert chemists Dr Colin Osborne from the Royal Society of Chemistry, and Dr Kay Stephenson and Bob Worley from CLEAPSS...

This Unilever Laboratory Experiment, published in 1973, describes two methods for determining the vitamin C in foods. The leaflet describes the estimation of vitamin C (L-ascorbic acid) in foodstuffs, after extraction with metaphosphoric acid, by titration with a standardized dye, 2,6 dichlorophenolindophenol,...

This Unilever Laboratory Experiment, published in 1970, describes the procedure for a titration with EDTA and Eriochrome Black T to determine the total hardness of water. The details cover the preparation of a standard solution of EDTA as well as the steps of the titration.

This mystery deals with a laboratory report in which the written results suddenly vanished. The students need to find out how the writing vanished,  how to recover the vanished data, and what the secret of the pen is.
