In this resource from SAPS, students learn about random sampling, diversity and different measures of abundance, before looking at close-up photographs of quadrats and using the field guide to identify them. The resources are intended to help students develop skills and plant identification techniques before going...

This online ecology practical, by SAPS, is designed to give students an opportunity to see how systematic sampling can be used to

• investigate changes in species richness across a footpath
• the distribution of species across a footpath

A podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC). With efforts to improve energy efficiency focused on green transport, sustainable power generation, growing your own food and reducing waste, it is often easy to forget that the very buildings we live and work in...

This Catalyst article explains how orchids have evolved over millions of years to have a close relationship with the insects which pollinate them. Like many plants, orchids rely on insects to carry pollen from one flower to another in order to reproduce. Many plants offer a reward to pollinators, and so do some...

Many of the chemicals we use as drugs, flavourings and perfumes originate from natural sources but often the most economical way of obtaining them is to produce them artificially on an industrial scale.

In this...

Produced by the Wellcome Trust Sanger Institute, this practical activity allows students to create an origami model of DNA, demonstrating its double helix structure. The activity provides a hands-on way of learning about the structure of DNA.

Two templates are available as PDFs; a standard template with the...

This report from Ofsted looks at City and Islington College which is one of the biggest national providers of science in further education. The college has developed a broad range of cutting-edge science provision and established itself as a regional centre of excellence for science.
