This comprehension activity, aimed at students aged 11-14, looks at the role of the immune system in protecting us from infectious disease, and how it recognises the difference between the body (‘self’) and invader. This worksheet is part of a collection of materials based on...

As the number of cells in a microbial culture increases, turbidity increases. In this experiment students calculate doubling time and growth rate constant using absorbance as the measure of growth. Turbidity is caused by suspended cells in the growth medium scattering light, and may be measured using a colorimeter...

This experiment is a continuation of Determining Doubling Time. Students create a standard curve of absorbance against yeast concentration, and use this to determine the concentration of yeast produced over time.

The standard curve (dry mass, grams per litre) is generated from known concentrations of dried...

This resource requires students to consider the challenges of designing and developing a new sports venue. To make this challenge more manageable, it has been divided into four separate challenges: the site, the structure, the court and the environment. As well as researching and developing ideas, the challenge is...

This activity, suitable for a cross-STEM project day or series of lessons, focuses on how information can be provided to travellers on the London Underground. Students are asked to consider user needs – what information would they need to see, and how might their requirements be communicated? A deep understanding...

This booklet contains a number of case studies of lessons that emphasise working with what students already know and working from concrete ideas to the abstract. Each case study explains the task, contains examples of students’ work and explains how the lesson was followed up. [b]The function game[/b] is one way in...

This National Strategies study guide offers tried and tested practical suggestions for teachers to use in the classroom when considering the teaching of How Science Works. A variety of tasks help teachers to focus on developing their own creativity and critical thinking, transferable skills which they can pass on...

This article, from the Association of Teachers of Mathematics (ATM) publication ‘Mathematics Teaching’, and is taken from MT180.

Judith Steven and Kym Scott argue the importance that primary school teachers plan activities for children’s mathematical development out-of-doors. The activities should be...

In September 2002, eight new General Certificate of Secondary Education (GCSE) courses in vocational subjects were introduced: applied art and design; applied business; engineering; health and social care; ICT; leisure and tourism; manufacturing; and applied science. This report covers the introduction of these...

In this resource from the DfE Standards Unit, students reflect on the reasoning they currently use when solving proportion problems, examine proportion problems and appreciate their
multiplicative structure and create their own variants of proportion problems. Proportional reasoning is notoriously difficult...

This booklet, developed for mathematics departments by the National Strategies, is based on materials developed by six working groups as part of QCA’s algebra and geometry project.

The project focused on the place of algebra and geometry in developing concepts and skills in reasoning. The booklet brings out...

The materials in this resource are from the Secondary National Strategy ‘Progressing to Level 6 and beyond in science’ project. They were intended for science teachers who are focusing on developing writing in science – specifically explanations, arguments and descriptions.

These materials consist of general...

In this resource from the DfE Standards Unit, students will learn to: use past examination papers creatively, explore, identify, and use pattern and symmetry in algebraic
contexts, investigate whether a particular case can be generalised further, understand the importance of counter-examples, develop the...

In this resource from the DfE Standards Unit students learn to use past examination questions creatively by selecting and using appropriate techniques and strategies to solve
problems involving numerical, graphical and algebraic manipulation. Most students will have solved problems such as these...
