This challenge, from Practical Action, requires students to design and build a model structure that will enable farmers to grow crops even in an area that may become flooded. A floating garden, built on a base of aquatic weeds, is a low cost and sustainable way of allowing people to grow vegetables. The resource...

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...

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.

This is one of a series of resources from the IET designed around the theme of the future of flight with the purpose of developing pupils knowledge and skills in science, design technology, engineering and mathematics. 

In this activity pupils calculate the amount of energy needed to launch a space...

This publication, from the Technology Enhancement Programme (TEP), looks at the topic of flywheels and how they can be used to store or smooth energy flows. The book initially provides information for students on the following topics:

• The energy-storage system
• Cyclicity of supply
• ...

This sub-collection includes shorter activities which can make effective starter and plenary activities, helping students to engage and further their understanding. The resources are:  

• Mr Zippy's Trainers: This brings together the ideas of friction, air resistance and materials using clear language...
