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...

Reaction Rates and Mechanisms *suitable for home teaching*

From Nelson Thornes, these resources help students to reinforce understanding about reaction rates, orders of reactions and the rate-determining step of a reaction. The activity challenges students to determine the order of a reaction from experimental data and deduce the reaction mechanism from this data. These...

Born-Haber Cycles *suitable for home teaching*

From Nelson Thornes, these materials are aimed at A2 level students and help them to understand the energy changes involved in Born-Haber cycles. The student activity sheet follows on from the study of Born-Haber cycles and the calculation of lattice enthalpies. The activities requires students to apply this...

COVID-19 Coronavirus Data

This resource includes data on the COVID-19 coronavirus outbreak that students can download, plot and analyse over time, starting from 22-01-2020. 

These Excel files include location, confirmed number of cases, deaths, number recovered, updated each day.  The data could be downloaded and combined so that...

What Are Stem Cells? *suitable for home teaching*

This Catalyst article explains the use of stem cells to treat medical problems, and outlines new possibilities for the use of adult stem cells in treatment.

Currently, stem cells used for treatment are embryonic stem cells, since they have the ability to form any cell type in the body. The example of the use...

Introducing Stem Cells *suitable for home teaching*

This presentation and collection of short activities, from Eurostemcell, introduce basic stem cell concepts and include teacher’s notes with each slide and useful diagrams. The materials include:

 Presentation: Introducing stem cells

• Stem cell biology basics: for post-16 students,...

What's in a Cell? *suitable for home teaching*

This Catalyst article explores the complex structure of cells, and numerous theories of how they were formed. It describes how the development of electron microscopes has allowed greater detail of cellular strutures and organelles to be understood. The article includes detailed electron micropgraphs, along with...

The Systems Physiology of Exercise *suitable for home teaching*

This Catalyst article looks at the effect exercise has on the body. Poor fitness contributes to poor life expectancy, and inability to exercise reduces quality of life in the ill or aged. Scientists hope to understand the mechanisms which limit 'exercise tolerance' which would contribute to enhanced performance for...

Spreading Aliens, Arctic Experience, and Antarctica *suitable for home teaching*

This podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC) looks at how hikers and walkers could be unwittingly changing the landscape by spreading alien species; what it's like to work as a marine biologist in the Arctic in temperatures of minus 40°C; and exactly how...
