• Paper and/or thin-layer chromatography to separate and identify analgesic...

Like ‘The Sims’, in this SimPhysics game students look after a family and keep their home supplied with electricity. In the game scenario the government has set a carbon dioxide quota for each household, so limiting their contribution to climate change. The player has to invest in renewable sources of electricity...

Students use algebraic and spreadsheet formulae in Excel to calculate simple and compound interest.

This resource is part of the Nuffield Maths Level 1 Foundation resource collection.

This Core Maths activity introduces the concept of simple and compound interest and its effect on the amount by which an investment grows over time. To complete the activity students will use an Excel spreadsheet to calculate and compare the interest amounts accrued.

A link is included within the teacher...

To increase confidence and fluency, students need to spend time practising the basic definition and rules of logarithms and be able to apply the rules in more complex expressions. This resource, from Susan Wall, contains four advanced level activities designed to practise the basics and extend understanding of...

This DfE Standards Unit resource enables students to develop their understanding of the laws of logarithms, practise using the laws of logarithms to simplify numerical expressions involving logarithms and apply their knowledge of the laws of logarithms to expressions involving variables. Students should have some...

This contains two excel programs with interactive spreadsheets designed to show the graphical solution to pairs of simultaneous equations and provide their solutions.
