Using this resource, from Defence Dynamics, students work as the Operations Team for a Royal Air Force (RAF) squadron on Quick Reaction Alert (QRA).

Presented with a series of imaginary scenarios, students have to review and plan routes for a number of aircraft facing different crises.

The lesson aims...

This resource consists of 11 instant maths ideas, ideal for use as starter questions, extension question or probing questions to assess understanding, requiring students to: * explain the use of bearings in practical activities * use bearings to crack a code * calculate the connection between the bearing of a...

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...

Even though computers are fast, there is a limit to how quickly they can solve problems. One way to speed things up is to use several computers to solve different parts of a problem. In this activity sorting networks are used to do several sorting comparisons at the same time. This resource begins with a discussion...

In this resource, students use their STEM skills to help them design and build a model of a flood- proof house. Activities to help them with their design include testing materials (for strength and absorbency) and structures. Set on a fictitious island coping with the devastating effects of flooding caused by...
