Who's Who? *suitable for home teaching*

This worksheet, from the Linnean Society, looks at speciation, dimorphic and polymorphic species and Batesian mimicry. In Batesian mimicry a palatable species mimics an unpalatable one, thus protecting itself from predation. Through a series of questions based on the text, the resource aims to explore this in...

Function Finders *suitable for home teaching*

Produced by the Wellcome Trust Sanger Institute, in this activity students translate DNA sequences into a series of amino acids to discover which protein is coded for and its function.

Students are supplied with a worksheet with DNA sequences and a codon wheel to decode the codons into amino acids. The amino...

Protein Synthesis - Prokaryotes and Eukaryotes *suitable for home teaching*

From Nelson Thornes, these activities encourage students to examine the process of protein synthesis. They look at the differences in this process in prokaryotic and eukaryotic organisms. Students are asked to consider the detailed mechanisms and assess the benefits of the different methods. These biology resources...

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...
