After learning about flooding, students consider the design problems caused by its early detection. Students are introduced to moisture sensors, and can build their own using the instructions provided or use a ready-made version. This is connected to the BBC micro:bit and used as an input device. After processing...

A fact sheet from the Geological Society about different kinds of flooding, river, costal, groundwater, urban and flash floods, and the role played by climate change in increasing the risk of flooding.

These videos highlight the problems caused by flooding in the developing world, and show how Practical Action works with local communities to help reduce the impact of future floo...

This task is designed to assess how well students understand:

• Angles in quadrilaterals
• Rotation
• Geometric reasoning and proof

The task examines a floor pattern. The first example shows two overlapping squares, both with the same centre, but with one rotated through 45...

This resource consists of a number of flow diagrams providing the steps required to calculate values of different properties of a variety of shapes and solids given differing starting points. Covered are square, circle, cube, sphere, cone, pyramid, sector of a circle, cylinder, rectangle. There is also a flow...

The aim of this experiment is to investigate the velocity of charged ions in an electric field. This is of the same order as the drift velocity of electrons in a wire under the influence of the same field.  A variety of analysis and conclusions that can be draw are provided.

This resource has been provided...

An introductory lesson, linking ideas from flowcharts to the use of pseudocode. The presentation may need some editing to remove school specific information. It contains a link to the "Friendship Algorithm" sequence from Big Bang Theory and a link to the description section for Algorithms and Pseudocode from BBC...

The numbers from 1 to 9 are to be placed on a grid superimposed on a flower. The challenge is to ensure that the total of each line gives an equal sum. This resource is designed to be used after the ‘Number Bond Garden’ puzzle. The resource is suitable for Key Stage 2 students.

This resource is designed as an introduction to deployable structures using flowers as an example from the natural world. It has activities associated with nets and density and discussion of a link to symmetry and transformations. There are also various practical suggestions (such as making a party blower).

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...

This booklet, in the Unilever Advanced Series was first published in 1970. The booklet explains the phenomenon of fluorescence in terms of bonding and antibonding orbitals. It then shows how synthesis of organic molecules can be used to make fluorescers that can act as...

This Catalyst article looks at the use of fluoride in water supplies. The UK health secretary has announced that more water companies would be encouraged to add fluoride to the water supplies. The article looks at why fluoride is added, what the advantages and risks are and why should it be put into water.

This poster describes four people in four different companies who all work together to produce an innovative flood defence system. To manufacture the produce requires the collaboration of designers, engineers, materials...
