What Causes the Aurora? *suitable for home teaching*

This article from Catalyst looks at aurora borealis caused by the interaction of the solar wind with the Earth's magnetic field. It also explains how satellites are testing thoeires of how this happens. Auroral light emission occurs at roughly 100 km altitude. Energetic electrons in the solar wind cause the...

The Other Genome Project *suitable for home teaching*

This Catalyst article details how the genome of a plant called Arabidopsis has been unravelled so that this species can act as a model in genetic studies. Arabidopsis thaliana is a model species like the fruit fly Drosophila, yeast, and the bacterium Escherichia coli.  Scientists...

Cell Signalling *suitable for home teaching*

Produced in 2014, this resource looks at cell signalling when the hormone adrenaline binds to receptors on the surface of the target cell. The resource sheets describe how the original hormonal signal is amplified through a cascade reaction.

Supporting videos explain key areas of working scientifically,...

Seeing Inside Cells *suitable for home teaching*

Each individual blade of grass consists of various tissues, each made of cells in their thousands. In these cells an as yet unknown number of reactions and interactions are constantly taking place. The cells contain different parts known as organelles, which can be thought of as the cellular equivalent of the...

Biodiversity *suitable for home teaching*

Sovon, a Dutch bird protection organisation, counts birds. The number of greylag geese is increasing. Students are asked to investigate whether this increase is worrying for the diversity of water bird species? Students explore what the concept biodiversity means, how it can be described mathematically and what are...

Molecules From the Past *suitable for home teaching*

A Catalyst article looking at how modern archaeology uses analytical chemical techniques to answer questions about ancient civilisations and animals. Scientists working at the University of Bristol match compounds present in archaeological materials to those in modern plants and animals which were likely to have...

Mass Spectroscopy *suitable for home teaching*

This resource looks at how cutting edge science is being used to answer archaeological questions, as well as solving present day problems, such as the identification of meat in processed foods. Analysis of mitochondrial DNA was performed, at the University of York, on samples from skeletal remains unearthed by the...

Plants and Medicine: Aspirin *suitable for home teaching*

This film, from Twig World, looks at the history of aspirin, which can be traced back to the Egyptians, where it comes from and what makes it so special. The key points made in the film are: •Aspirin originates from an ancient plant remedy used by the Egyptians. •They chewed willow bark to relieve pain and fever...

Esters and Perfumes *suitable for home teaching*

This film, from Twig World, looks at esters which occur in nature and have been harnessed by the perfume industry. It explores what esters are and how are they made and used. The key points in the film are: •Esters give many fruits their scents, including bananas, lavender and pineapples. •They are produced by a...
