### Prepare your own Solar Cell

Renewable energy is generally considered as being from an energy resource that is replaced rapidly by a natural process such as power generated from the sun or from the wind. Most renewable forms of energy, other than geothermal and wave power, ultimately come from the sun. Visible light can be converted directly...

### Planarity

Many topological graphs have edges that cross. The aim is to re-draw the graph in such a way that none of the edges cross. The task informs students they are required to design a printed circuit board and since the wires are not insulated they must not cross.

Planarity: presentation - an...

### 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. [

### Milk of Magnesia Extemporaneous Preparation

This activity, from the Royal Society of Chemistry, involves the preparation of milk of magnesia used as a treatment for indigestion. It is an example of an inorganic compound which can be used as a medicine and is an alternative to the more traditional preparation of inorganic salts such as copper (II) sulphate....

This handbook of magical mathematical tricks is intended for use in the classroom to help teach many of the basic concepts in mathematics in an engaging and entertaining way. The tricks have been mapped to topics found in Key Stage Four and are as diverse as Pythagoras' theorem, simultaneous equations, probability...

### 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...

### Manual of mathematical magic

Many of the most powerful magical effects performed today have a mathematical basis. Mathematics is also the secret behind the technologies people use, the products they buy and the jobs they will have. This book shows how to perform some magic tricks, explains the mathematics behind them and how that same...

### Making waves: acoustic engineering and sound control

In this activity students investigate the absorption of sound in the context of a sound engineer developing a performance space.

Equipment needed:

Microphone, speakers, computer and other generally-available materials.

### Magnetic Math

This series of activities from NASA take a mathematical approach to looking at magnetism. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 14 to 19 years.

The problems were created to be authentic glimpses of modern...

### Lunar Math

This series of activities from NASA take a mathematical approach to looking at Lunar exploration. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 11 to 19 years.
