### Friction

This simulation can be used to demonstrate how friction causes a material to heat up and melt. It shows how when two objects are rubbed together they heat up. When one reaches the melting temperature, particles break free as the material melts away. Sample learning objectives include: *Describe a model for friction...

### Vectors *suitable for home teaching*

Mathcentre provide these resources which cover aspects of vectors and are suitable for students studying mathematics at A Level, as well as those students for whom mathematics is an integral part of their course. Some of the topics covered include an introduction to vectors, calculating the vector and scalar...

### An Old Principle Saves Energy *suitable for home teaching*

From Nelson Thornes, this resource helps students studying physics at post-16, A2 level. In this activity students read a short passage, on the workings of a condensing boiler, then answer questions on latent heat and specific heat capacity. The calculations should improve their comprehension and estimation skills...

### 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...

### Who Are You? *suitable for home teaching*

The Linnaean collections hold many types of specimens (the first member of species to be scientifically described) for taxonomic study. Making use of the Linnaean collection online, this worksheet focuses on Hymenoptera (including bees, wasps and ants). It looks at the importance of the hymenopterans, particularly...

### What's in a Name? *suitable for home teaching*

This worksheet in this resource introduces students to the topics of classification and binomial nomenclature. The idea of hierarchy is illustrated, before explaining Linnaeus’s system of classification and the terms kingdom, phylum, class, order, family, genus and species. There is also a useful introduction to...

### Investigating the Concept of a Niche *suitable for home teaching*

From Nelson Thornes, these activities encourage students to consider their understanding of an ecological niche. Students investigate the idea of a niche and look at the concepts of a fundamental niche and a realised niche. They are also asked to use information on a particular species’ niche, to predict where we...

### 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...

### 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...
