This booklet provides useful guidance on how Level of Response questions should be approached by students and how they are marked.

LoR questions allow students to be credited for demonstrating

• their scientific knowledge and understanding and their ability to...

This Handbook is intended as a resource for teachers, to clarify the nature of the mathematical skills required for A level biology, and indicate how each skill is relevant to the biology subject content.

Contents include:

Arithmetic and numerical computation...

This online ecology practical, from SAPS, uses random sampling to measure the abundance of various different species on an area of grassland.

Objectives

To give students practice at

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

These online exercises are not intended as a...

Produced by Becta, these case studies illustrate how information communication technology (ICT) can be used to enhance teaching and learning in science. This case study looks at use of PDAs during an A-level biology field study.

PDAs, also called 'handhelds' or 'palmtop PCs', are relatively cheap and robust...

In this practical investigation, students measure the rate of photosynthesis in plants from different habitats (sun and shade), and then consider what this demonstrates about leaf adaptation.

When leaf discs are...

Plant Physiology is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education by John Murray. Each title covered one or two topics and brought together the best of the teaching notes and...

One of a series of articles for post-16 students published by Science and Plants for Schools (SAPS). Plants attacked by herbivores or pathogens respond by synthesising additional physical and chemical defences and so increasing their resistance to subsequent assaults. The induced defences are initiated close to the...

There are 19 investigations here which you can weave throughout your scheme of work to ensure students have plenty of opportunity to practice key microbiology techniques, as well as using interesting contexts to teach a range of biological concepts.   If you're a little rusty on some of the techniques, have a look...

Produced by LSIS, this interactive resource aims to support classroom practitioners in improving the quality of learning in practical science sessions. It is not a set of suggested practical activities to use in the classroom. Instead, it provides a framework for clarifying and achieving learning outcomes through...

These resources explore proteins by their different function, with examples of how they give structure to living things, carry messages and molecules around our bodies, support the immune system, catalyse chemical reactions, and their use in industry and medicine:

Structure and movement How...
