This is a modelling activity where students use sampling techniques to determine the distribution and abundance of organisms in a simulated habitat. Students will simulate the mark–release–recapture technique (Lincoln Index) for estimating population sizes of mobile species.

Through the use of detailed case studies and scientific theories, the books in the 'Timeline: Life on Earth' series discuss how changes are studied, what the evidence reveals, and how such changes have had - and continue to have - an impact on Earth.

This series explains how the diversity of life on Earth has developed through gradual processes of change occurring over millions of years with this title focusing on how and why different species are distributed...

This item is one of over 25,000 physical resources available from the Resources Collection. The Archive Collection covers over 50 years of curriculum development in the STEM subjects. The Contemporary Collection includes all the latest publications from UK educational publishers.

This challenge enables pupils to model and test filters as a way of making dirty water cleaner. It can also be used to explore ways of making water safe to drink.  Curriculum links include separation techniques and pure substances.

The challenge can provide a focus for National Science and Engineering Week,...

This resource from Farming & Countryside Education (FACE) allows students to investigate how different farmers have addressed the challenge of sustainability, and the solutions they have devised to remain in business despite the serious long-term problems faced by the sector. The farm profiles help the students...

This activity provides a mathematical problem that is solved in a simple way. It relates to the way algorithms are used in search engines and links to problem solving in maths. The context is that of Santa trying to find his socks in one of 1024 boxes, which a clever elf solves for him. Children can then go on to...

The 'Maths matters!' series recognises the different approaches that can be taken to this subject, by presenting alternative ways of learning that suit any preferred method of handling mathematics. This book focuses on division.

'Dividing - moving ahead' builds on the basic concepts of maths using lively, colourful examples and simple games.

This resource, from the Centre for Innovation in Mathematics Teaching, uses diagrams to illustrate division by a fraction and, to clarify the common misconception identified with this task, prompts students to rethink the statement, divide three by one quarter, as the number of quarters that fit into three....
