A Catalyst article about the composition of sea water. The article looks at how the sea became salty, how the factors such as hydrothermal systems can affect it and it investigates whether its composition has always been the same.

This article is from Catalyst: GCSE Science Review 2005, Volume 15, Issue 3....

This podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC) was recorded at the Diamond Light Source in Oxfordshire, England and discusses how two researchers are using hi-tech physics to study different aspects of the environment.

The Diamond synchrotron is like...

This resource, produced by the Earth Science Teachers' Association consists of three units which investigate the effects of heat and pressure on rocks through a series of practical assignments. Many of the activities are suitable for group work, although some may be set...

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...

The aim of this resource is to answer the question how do CO₂ emissions link to global temperatures? This lesson, linked to the Intergovernmental Panel on Climate Change (IPCC) report, explores the concept of a carbon budget. To answer the question, students create a pie chart to...

This lesson, linked to the Intergovernmental Panel on Climate Change (IPCC) report, aims to answer the question 'How often will a heatwave hit the UK?'

Students examine datasets to explore the frequency with which hot events occur and are required to interpret and draw box and whisker plots. Students are...

This text, produced by the Geological Society, investigates igneous, metamorphic and sedimentary rocks, the rock cycle, erosion and weathering. The book contains a series of classroom activities for earth science at Key Stage Three. Each unit provides preparatory information for the teacher, information sheets for...

A Catalyst article about the Hubble telescope exploring a barred spiral galaxy, known as NGC1672 in the astronomers’ New General Catalogue. The image was made by the Hubble Space Telescope (HST), and was released in April 2007. NGC 1672 is situated 60 million light years away, in the constellation of Dorado. The...

In this activity, from the Royal Observatory Greenwich, students look at their shadow at different times of the day and measure differences in its size and direction. The activity needs to take place in the playground on a sunny day. A compass or an online map can be used to help work out which way is North on the...

A Catalyst article about Hurricane Katrina which caused many deaths in August 2005, and vast damage along the coastline of the Gulf of Mexico in the USA. Hurricanes are an unfamiliar phenomenon here in the UK. Why is this? And can people expect to see more hurricanes in future as a result of climate change? The...

In this resource, students attempt to apply their understanding of heat transfer (convection, conduction and radiation) to the novel case of the Beagle 2 Lander.

Students are set the challenge of creating the best...

In this podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC), Sue Nelson visits the ice cloud chamber in the School of Earth, Atmospheric and Environmental Sciences.

Scientists know that fluffy stratocumulus clouds act like a blanket on the Earth - they stop...

A Catalyst article about giant asteroids. Astronomers say that, one day, a giant rock from space will collide with the Earth and cause mass devastation. This could lead to the extinction of many species, including humans. The article looks at what can be done to prepare for such an impact and what happened when a...

There is a minimum size of meteorite that will make it through the atmosphere of a planet (or the Moon) and impact on the surface. If the meteorite is any smaller than this, it will burn up on its journey through the atmosphere and be seen as a meteor or shooting star (obviously if the meteorite is bigger it will...

In this resource students are asked to extract data from a fact sheet on the impact of global warming on the Polar regions and present it in the form of an annotated spider diagram.
