This resource contains two interactive excel files dealing with trigonometry in right angled triangles. Each interactive file has the same further 13 sheets of questions which may be suitable for use in the classroom.

This interactive excel file begins with a sheet showing a compass rose to help students estimate the bearing of the direction shown. The next sheets allow students to estimate bearings between points shown on a coordinate grid. To calculate the bearings students would...

This simulation explores the Beer's Lambert Law. It allows you to make colourful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer.

Curriculum links include:

• Beer's law
• Solutions
• Concentration
• Molarity...

Sovon, a Dutch bird protection organisation, counts birds. The number of greylag geese is increasing. Students are asked to investigate whether this increase is worrying for the diversity of water bird species? Students explore what the concept biodiversity means, how it can be described mathematically and what are...

In this activity the goal is for students to understand how the regression line is chosen. Autograph has a built-in facility for showing the squares of the residuals and is required to make this task work. Students are asked to explore what the lines that give the sum of the y-on-x residuals equal to zero have in...

This excel file has four interactive sheets dealing with the order of operations. The first shows groups of calculations involving addition, subtraction and multiplication where the answers can be revealed. The second interactive sheet is similar, but it deals with...

In this Core Maths resource students are asked to evaluate the offers and figures from three banks in order to decide which one is best for their company to borrow from. The resource involves students calculating the interest incurred using an Excel spreadsheet.

The first sheet of this excel file shows a box and whisker diagram where the defining points can be altered. The second sheet shows two box and whisker diagrams to allow comparison between distributions. The next sheet shows a box and whisker diagram for students to...

This resource contains two excel programs; ‘Removing and Collecting Like Terms’ and ‘Multiplying Out and Simplifying’, each containing a series of interactive spreadsheets designed to explore how to deal with brackets.

A set of simple scratch ‘debugging’ activities that children can use to apply their understanding of programs and codes.  Children are shown a series of faulty programs which are based around the water cycle.  They are then supported to use logical reasoning to locate and fix the bugs within them.  Notes for...

This is a classroom-based activity from the Wellcome Trust Sanger Institute that allows students to explore the features of two bacterial pathogen genomes. The aim of this activity is to highlight the role of different genetic components in two closely related subspecies of Salmonella enterica, and to identify how...

This simulation allows you to build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Students can then play a game to test their ideas.

Curriculum links include:

• Atoms
• Atomic Structure
• Isotope Symbols
• Atomic Nuclei...

This series of Core Maths activities involves mortgage finance, interest rates, income tax, national insurance, scheduling, Gantt diagrams and estimation. The tasks can form a large project or be used as stand-alone lessons.
