A Catalyst article about increased levels of carbon dioxide causing global warming. The atmosphere is being polluted when fossil fuels such as petrol are burnt releasing carbon dioxide. Despite concern about global warming, it seems nobody wants to use their cars less. The article looks at what can be done to...

A Catalyst article describing the species that have had the greatest impact on planet Earth during its billions of years of history. Which come out on top of the 'league table of life'? As hominids have only walked the Earth for part of its existence the article looks at the history of life, from the dawn of...

This Catalyst article describes how the human body is affected by low atmospheric pressure at high altitudes. The article looks at the dangers that await the unwary traveller and explains how, if people understand their bodies, they can avoid the worst problems of life at high altitudes.

This article is from...

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...

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...

A Catalyst article about International Heliophysical Year (2007-08) - a year of scientific collaboration, studying the Sun and the impact of its radiation on the Earth. How the Sun is changing and the history of solar research is examined.

This article is from Catalyst: Secondary Science Review 2007, Volume...

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...

A Catalyst article about the Kepler spacecraft, which is used to look for extra-solar planets. Scientists are hoping to shine light on the age old question of life’s existence elsewhere in the Universe using a new space-based telescope named Kepler. Launched on 6 March 2009, Kepler is searching the sky for small,...

This Catalyst article investigates the development of better, more energy-efficient solar cells. Every minute enough sunlight strikes the Earth to power our civilisation for a year, yet less than 1% of global energy generation is provided by solar energy. Solar cells convert sunshine directly to electricity, but to...

A Catalyst article looking at the use of plant cells to generate electricity via photosynthesis. This branch of science is called biophotovoltaics. The Sun is the ultimate source of energy for almost all life on Earth and harnessing this energy is one of the great scientific and technological challenges....

Published in June 2015. Thinking, doing, talking science (TDTS) is a new approach to primary school science that...
