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...
In this Catalyst article, Mike Follows describes the surprising range of thermometers available to scientists today.
Many physical properties of materials depend on temperature. Thermometers are vital for measuring body temperature. The body's biochemical reactions work best at 37°C and the body is in...
Geothermal energy is the heat produced by decay of radioactive isotopes deep within the Earth. The temperature at the centre of the Earth is thought to be around 5,000°C, with the temperature reducing toward the surface. It is estimated that 99.9% of the planet is above 100°C. Geothermal energy is considered a...
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...
This edition of the magazine from the UK Space Agency includes:
- The launch of the Earth Observation satellite, Sentinel 2A
- News about the Rocket (salad) Science experiment
- Tim Peake's training for his mission to the International Space Station
- The launch of the International...
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...
This booklet, from Science Community Representing Education (SCORE), offers a range of practical activities for use in the classroom. Most are aimed at Key Stage Three and Four and Post-16 students but a small number are provided for Key Stage Two to highlight the...
This issue of Catalyst contains the following articles:
...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....
This edition of Computer Science for Fun is entitled ‘The Earth Issue’, and features computer science applications that are environmentally friendly or that have helped scientists researching our planet.
The articles include:
• The power efficiency of the human brain vs modern computers
•...
This Catalyst article looks at the Rosetta mission: to rendezvous with Comet 67P/Churyumov-Gerasimenko where it will study the nucleus of the comet and its environment for nearly two years, and land a probe on its surface. The article also describes how gravity assists, also known as slingshot manoeuvres, are used...
Mathematics Subject Specialist, Michael Anderson, discusses the questions the Principia mission poses, as well as the range of support materials available to teachers as Tim Peake returns to Earth from the International Space Station.
Gill Collinson, Head of Centre, National STEM Learning Centre and Network...
