These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Identify objects that are floating.
• Describe how the mass and volume of an object affect how well it floats.  
• Describe how the shape of an object affects how well it...

In this lesson, students devise their own flood warning device and create a technical brief for an international audience using recognised circuit symbols. They also consider how people both here and in Nepal can best prepare for floods. Heavy monsoon rains can devastate communities in Nepal. The severe flooding...

Students work in teams to design and make a prototype device that can design and make a prototype of a simple device (to be sold in stores like B&Q) that will allow homeowners to remove water from their house during periods of flooding.

In this challenge the device will have to move 100ml of water from...

This podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC) looks at why removing some man-made coastal flood defences might not be such a bad idea, what it is like studying gas exchange in the wilds of the Southern Ocean, and – in what could be the first case of '...

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...

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...

The Young Scientist Investigates topic book on Flowers, first published in 1981, gives information, about the wide range of flowers, their structure, pollination, germination and growth. It is beautifully illustrated with full colour photographs and drawing. It is...

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 Catalyst article explores how high-speed photography can reveal how mosquitoes can keep dry while flying in the rain.

To find out how mosquitoes survive impacts with raindrops, a group of engineers from Georgia Institute of Technology (USA) developed a system which allowed them to photograph collisions...

This Catalyst article looks at what it means to say that an astronaut is 'weightless'. The article looks at how astronauts are trained in aircraft and how underwater work can also help prepare them for space travel.

This article is from Catalyst: Secondary Science Review 2008, Volume 19, Issue 1.
