This Catalyst article looks at OIF (Ocean Iron Fertilization) a process of pouring iron into the oceans. The theory behind it is to slow climate change by using a process that already occurs naturally. Nature has a way to draw carbon dioxide (CO2) from the air down into the ocean. If the process could be speeded up...

The texts for Revised Nuffield Biology offered an amended version of the third year of the five-year course to O-level. The revision was based on the experience of numerous teachers with the original edition. Extra...

In this lesson students look at the related concepts of pressure and force (pressure = Force/ Area), units used, measurement and how a large force can result from pressure acting over a given area. They will move from calculating the weight (under gravity) of a column of water or air to the pressure of this as...

Aimed at primary level, this pack contains a range of different activities which and are intended to stretch the imagination. The activities cover a mixture of topics including: materials and their properties, Earth and Space,...

This podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC) looks at how carbon capture and storage works, why it's here to stay, the effect of floodplains on water pollution, and how the thickness of polar ice can be measured from space. The venue for this Planet Earth...

This podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection looks at the cunning tricks the cuckoo uses to get another bird to do the parenting, why researchers are studying snow in Sweden, and discovers an improved radiocarbon dating technique.

The cuckoo is a well-...

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

• Describe how gravity acts on objects near to the Earth

• Describe how gravity acts towards the centre of the Earth (or other astronomical body)

• ...

This podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC), looks back at some of the highlights from 12 months of Planet Earth podcasts, and looks ahead to some of the big stories expected in 2010.

Marine biologist Ben Wilson from the Scottish Association for...

Karsten works at the University of Leeds as a scientific researcher, in the School of Earth and Environment.  He uses images taken by satellites to look the movement of structures such as railways, roads and gas lines.  He also examines the movement of the Earth due to volcanic eruptions and earthquakes. ...

A podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC). With efforts to improve energy efficiency focused on green transport, sustainable power generation, growing your own food and reducing waste, it is often easy to forget that the very buildings we live and work in...

A Catalyst article about the use of remote telescopes and detecting cosmic rays. Giant telescopes that can be operated remotely are located in Hawaii and Australia and are known as the Faulkes telescopes.

These are available to students in the UK to do original research with, and enable the following...
