In this resource students are given an image of a reciprocal curve, y=k/x. Two tangents to the curve are used, together with the coordinate axes, to form an 'arrow head' quadrilateral under the curve. The challenge is to determine the area of the quadrilateral.

The first step towards solving the problem...

Produced by the Wellcome Trust, these resources include an interactive evolutionary tree and a video of the Tree of Life. These materials will help students to find out more about the work of Charles Darwin and evolution. The resources contain:

Tree of life video: The video is a short...

This resource, from the Royal Observatory Greenwich, looks at what information we can gather by viewing (but not visiting) different parts of the universe. 

The...

Students investigate why some plastic cups collapse when filled with hot water and some don't.  They compare the effect of hot water on a range of cups and relate their findings to the properties of the plasticsused for each cup:  whether it is biodegradable or not, its melting...

In this resource a presentation and linked activities provide design and technology teachers with opportunities to highlight the different values and beliefs that designers may hold. Students can engage in exploring their own values about the responsibilities of designers and companies too. The presentation ...

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...

A multiple choice quiz on medicine for  AS/A level chemistry.

Although it is written for OCR AS/A level chemistry (Salters) H033/H433 course, it can be edited to suit your scheme of work.

A function is defined so that f(xy) = f(x) + f(y) for all positive integers x and y. Students are given the value of f(10) and (40) and are challenged to determine the value of f(500).

In each student worksheet contains different values for f(10) and f(40) but for...

The aim of this investigation is to find the value of a number of resistors using a Wheatstone bridge.  Although this is an historical piece of equipment that has been superseded by modern methods it provides an excellent way to understand potential difference in circuits.

This resource can be used as an introductory exercise into mathematical modelling. The problem is to decide on the winning team in a race. Students need to examine the data and decide on a model to determine the winner.

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...

Produced by ARKive, a database of stunning natural history images, this activity is designed to teach students aged 11 to 14 about the identifiable features of different types of animals and how they are classified. The activity is also suitable for students aged 14 to 16 and beyond. Using a quiz format, students...

From the Learning and Skills Improvement Service, this activity prompts students to analyse and justify decisions about responsibilities in relation to accident prevention.

Students are required to:
* Explain some reasons why accidents happen at work
* Decide what responsibility means for...

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...
