In this resource from the DfE Standards Unit, students learn to interpret decimals using metric units, estimate lengths of real life objects and interpret standard form.They will also discuss and understand these processes. Some students will have encountered decimals and standard form before. The opening...

This set of resources are based on Birmingham Institute of Forest Research (BiFoR) work. The activities provide an innovative way to introduce the issues surrounding the estimation of biomass. For pupils aged between 11 and 14 there are engaging activities to introduce the concept of biomass and pyramids of biomass...

Students compare the water quality at different points in a stream or river using the standard procedure for finding the Trent Biotic Index score for samples of freshwater invertebrates.  The test was developed by the Trent River authority to detect water pollution. It allows comparisons of water quality to be made...

This lesson develops the concepts of estimating the lengths of everyday objects, and converting between decimal and scientific notation.

An introductory activity looks at converting between decimal and scientific notation.

The main activity involves a collaborative exercise centred around picture...

Produced by Science & Plants for Schools (SAPS), in this investigation, students look at the concentration of glucose in isotonic sports drinks. This enables students to see if the drinks are, in fact, isotonic with the blood.

In this investigation, students first produce a standard curve by testing...

This is a problem solving lesson, designed to help you assess how well students are able to:

• Model a situation.
• Make sensible, realistic assumptions and estimates.
• Use assumptions and estimates to create a chain of reasoning, in order to solve a practical problem.

This...

This MEP resource from CIMT is taken from text book 9B which covers the mathematics scheme of work for the second half of year 9.

Estimation and approximation covers: rounding to the nearest 10,100,100, rounding to significant figures, rounding to decimal places, estimating calculations by rounding to one...

This resource begins with estimating by rounding to significant figures, then deals with estimations and predictions in real life scenarios. Fermi estimation is then introduced. The question ‘Is climate change happening?’ is also posed.

From the National Non-Food Crops Centre, this factsheet gives an overview of the current and potential market for biorenewable ethanol in chemical applications. It explores the production and uses of bioethanol. Bioethanol can be produced by the fermentation. Starch and sugar feedstocks are also food crops and so...

Produced by Science & Plants for Schools (SAPS), this investigation looks at the effects of ethene of fruit ripening.

Ethene is a colourless gas and is produced by plants, acting as a plant growth substance. Its...

This resource, designed for Key Stage Four, provides an introduction to organ and tissue donation, looks at different levels of intervention to encourage people to donate, and explores the meaning of ethical values that are often used in the context of donation. It also...

The first video introduces a range of concerns surrounding computing technologies.  The idea that new technologies bring with them new social and ethical issues, and that the law is often slow to catch-up to guard people against these issues.  Some of the benefits of new technologies are briefly introduced,...
