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...

Galapagos Conservation (Ages 16-19) *suitable for home teaching*

From ARKive, these resources help students to learn about the Galapagos Islands, their biodiversity and conservation. Through a series of activities, students look at: * the scientific history and importance of the Galapagos Islands * the species that inhabit the islands including the concept of endemic species *...

Redox Titration *suitable for home teaching*

From Nelson Thornes, these materials are aimed at A2 level students and help them to reinforce and practise their understanding of redox titration calculations. These include redox titrations involving iron, copper, manganate, sulfate and dichromate ions.

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...
