A Catalyst article about Darwin's travels on the Beagle which gave him ideas about evolution. Darwin spent almost five years on board HMS Beagle as it sailed around the world. The purpose of the voyage was to map navigation channels around the coast of South America. Darwin was the ship’s naturalist and companion...

This resource from the European Space Agency climate change resource pack explores the topic of biodiversity and how habitat loss is a key driver of global biodiversity loss occurring today. In a series of activities students explore the importance of biodiversity focusing in particular on distributions of common...

This SATIS Revisited resource looks at the environmental and ecological consequences of further expansion of biofuel crops due to deforestation, biodiversity and landscapes.

Biodiesel is a fuel derived from biomass (...

This Catalyst article describes how, as two tectonic plates separate, wide fissures appear in the ground in northern Ethiopia. Eventually a new ocean will form in the area affected. The Earth’s surface is not stable or permanent. The tectonic plates that form our planet’s outer crust are constantly moving around,...

Produced by Twig, this animated video is a clear and accessible explanation of how the Solar System fromed. The video describes how:

* the solar system grew from a ball of gas which formed the Sun

* gravity caused heavy material to cluster together and eventually form planets

* the inner...

A podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC). Richard Hollingham finds out that bowerbirds are not just brilliant at making elaborate bowers, they are also good at mimicking other birds and most other sounds they hear, including human voices.

He also...

This podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC) looks at what UK farmers are doing to protect the country's vanishing bumblebees, butterflies and other pollinating insects; how scientists are trying to figure out how many types of microbes there are on our...

In this podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC), Sue Nelson goes to the Eden Project in Cornwall, southwest England and to the South Downs in southeast England to find out what butterfly research is telling us about climate change. As well as the bad news...

In this activity students consider the questions:

• Why is the car manufacturer interested in planting trees?
• How much pollution do cars cause?
• How can plants compensate for car pollution?
• What...

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...

A Catalyst article about carbon dioxide which can be used as a solvent in industry, or as a regulator of blood pH. This article looks at some other uses of carbon dioxide and considers its importance in global warming. It also explains how the greenhouse effect is a natural part of the operation of the Earth's...

In this SATIS Revisited resource students consider the factors that contribute to the greenhouse effect, the possible effects of global warming, and how they as individuals are contributing to carbon dioxide emissions.

Climate change is affecting the natural world. The distribution of some species appears to...

A Catalyst article explaining how scientists with qualifications in ecology and environmental science play an increasingly important role in assessing the human impact on the Earth. Ecology is the branch of biology that looks at how organisms, plants and animals, depend on each other and their surroundings. It also...
