This Unilever Laboratory Experiment, published in 1970, describes the analysis of fluorescers from soap and soapless detergent powders. The procedure describes how the fluorescers can be extracted from the product, separated by thin layer chromatography techniques, and made visible by exposing the chromatograms to...

The properties of a transformer are investigated in this video, specifically how the number of turns on the coils affects the output. 

This teaching package, aimed at Key Stages Two and Three, investigates the science of tree rings (dendrochronology). Linked to the topics of plants and living things and their habitats, it looks at cut tree trunks to determine the age of the tree, how fast it grew and...

Produced by Solar Spark, this simple activity helps to answer the simple, yet complex question: Why is the sky blue and the sunset red? It's all to do with light scattering and the Tyndall Effect and can be easily demonstrated using a suspension of milk in water.

Milk particles suspended in the water cause...

Whey is a waste product from the cheese industry. In this experiment students upgrade whey, by converting the lactose into glucose and galactose, or by growing the microorganism K.lactis on agar containing whey.

This resource, aimed at primary level, provides a complete guide to amphibians and reptiles in urban areas, including how to identify them, where to find them and how to create a habitat which encourages them to thrive.

The ID guide includes ideas on where to look to find reptiles and amphibians and tips on...

These activities provide the standard procedures for methods which may be employed to measure blood pressure at the beginning and end of a fitness programme. Methods are provided for automatic digital devices, for using a manually inflated cuff and stethoscope and for ambulatory blood pressure monitoring. 

This video demonstrates a simple experiment to investigate the principle of moments.

Produced by The Centre for Industry Education Collaboration (CIEC), the activities in this resource allow students to examine science concepts applicable to the healthcare industries and the work of people in the sector.

The activities in the resources cover areas that include:
* Determination of the...

This resource pack can be used to highlight issues such as global water scarcity, the challenges people face when sourcing water and maintaining a water supply in developing countries and the role of the engineers in solving these problems.

Following a quick quiz, a presentation introduces the scale of local...

This investigation, produced by Science & Plants for Schools (SAPS), shows how students could investigate the changes in water potential of fruits and vegetables during ripening and storage.

Simple biomechanical...
