Modelling a robot arm

In this activity students design and model a 3D robot arm. Robot arms are an example of a programmable system. They are used in a wide variety of industrial applications, ranging from loading machines to assembling cars, welding parts together and spray painting products. They are also used in applications such as...

Minimum Spanning Tree

The aim of a minimum spanning tree is to connect every vertex of the network using the edges having the least possible total weight. The task requires students to analyse information about a town centre and suggest which roads should be pedestrianized. [

Minimum spanning tree: presentation...

Mathematical Trickery

These resources, from the Maths Careers website, looks at the maths behind a variety of magic tricks and was created in conjunction with More Maths Grads and the University of Leeds. Tricks and ideas include those from Rob Eastaway, Johnny Ball and others.

The resource package includes a PowerPoint...

Matchings

A matching is a set of edges on a bipartite graph in which no two edges share a common vertex. A bipartite graph consists of two sets of vertices X and Y. The edges only join vertices in X to vertices in Y. A matching in a bipartite graph is the pairing of some or all of the vertices in X with some or all of the...

Flows

The network flow problem involves finding the optimum route through a flow network; a directed graph where each arc has a capacity and each arc receives a flow. Typical examples include: evacuation plans and delivery services. The problem involves students analysing the plan of a school canteen and deciding whether...

Dijkstra's Algorithm

Dijkstra's algorithm finds the shortest path for a given problem. Dijkstra's algorithm can be used to find the shortest route between two cities. This algorithm is so powerful that it not only finds the shortest path from a chosen source to a given destination, it also finds all of the shortest paths from the...

Curved Fold

This resource, from the Royal Institution, provides students with the opportunity to explore the formation of a parabola through a paper folding activity. Students follow a set of simple instructions which describe how to fold a piece of A4 paper and are asked to describe what shape is produced. The activity is...

Cryptic Challenge

This resource, from the Maths Careers website, contains a quiz in which teams have to solve a different type of code of cypher in each round.

The topics covered include mobile texting, transposition of messages, pencil code, binary and frequency analysis.

The activity was written in conjunction with...

Beat the Flood STEM challenge

In this resource, suitable for Key Stage Two to Three (age 7-14), 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...

Bin Packing

The purpose of bin packing is to pack a collection of objects into containers called bins. The bins are all the same size and the objects to be packed are different sizes. The aim is to pack the objects into the bins using the fewest possible bins. In this example students are asked to save computer files onto a CD...
