Catalyst Volume 18 Issue 4
This issue of Catalyst contains articles on:
Body Sensors Networks
This article describes body sensor networks which are tiny electronic sensors used to monitor the movement of patients, athletes and game players.
Cool Chemistry
This article draws on the work of a scientist from the British Antarctic Survey, gathering data about climate change.
To Sleep...Perchance to Dream
It is known that it is possible to study the electrical activity of the brain during sleep. But why do people sleep? Nobody really knows!
Ancient Air in an Antarctic Ice Core
Ice cores from Antarctica contain air bubbles which record the changing atmosphere. This evidence is vital in understanding how our climate is changing.
Careers in Ecology
Scientists with qualifications in ecology and environmental science play an increasingly important role in assessing the human impact on the Earth.
Earth's Early Atmosphere
By studying ancient rocks and sediments, scientists can deduce how the Earth's atmosphere has changed over billions of years. There used to be much less oxygen than today.
Probiotics, Prebiotics
The human gut hosts many microbes, mainly bacteria. What role do they play, and can people change their diet to encourage 'good bacteria'?
Is Mars Dead?
This article draws on the new data suggesting that it is very unlikely that life ever existed on Mars.
Catalyst is a science magazine for students aged 14-19 years. Annual subscriptions to print copies of the magazine can be purchased from Mindsets.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment.
Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date.
Since that time there have been significant changes in the rules and guidance affecting laboratory practical work.
Further information is provided in our Health and Safety guidance.
Body Sensor Networks
A Catalyst article about the use of tiny electronic sensors to monitor the movement of people. As electronic devices get smaller and more powerful, they are finding new uses in monitoring human activity. This article describes a project to develop sensors with uses in medicine, sport and electronic gaming. This article is from…
Cool Chemistry
A Catalyst article about the work of a scientist from the British Antarctic Survey, gathering data about climate change by studying ice cores from Antarctica. One of the areas of research was to find out whether it is possible to learn how much sea ice there was around Antarctica in the past by measuring how much sea salt is in ice…
To Sleep...Perchance to Dream
A Catalyst article about the study of electrical activity of the brain during sleep. The article looks at brain waves, REM (Rapid Eye Movement) and the effects of sleep deprivation. This article is from Catalyst: Secondary Science Review 2008, Volume 18, Issue 4. Catalyst is a science magazine for students aged 14-19 years.…
Ancient Air in an Antarctic Ice Core
A Catalyst article about ice cores from Antarctica which contain air bubbles which record the changing atmosphere. The Antarctic ice sheet is over 3 kilometres thick; ice cores enable scientists to sample each year of snow fall in sequence. This evidence is vital in understanding how the climate is changing. The article explains…
Careers in Ecology
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 looks at how humans…
Earth's Early Atmosphere
A Catalyst article about how the study of ancient rocks and sediments can help deduce how the Earth's atmosphere has changed over billions of years. There used to be much less oxygen than there is today. This article describes how the composition of the atmosphere has changed through history; it also explains the link between…
Probiotics, Prebiotics
A Catalyst article about the human gut and the many microbes it hosts, mainly bacteria. Probiotics are live bacterial ingredients or supplements designed to multiply in the colon and have an impact on health. A prebiotic is a carbohydrate that is not digestible by humans. The article examines the role they play, and looks at ways…
Is Mars Dead?
A Catalyst article explaining how new data suggests that it is very unlikely that life ever existed on Mars. When the presence of water was confirmed a few years ago, there was a lot of speculation that at least simple life forms had once lived there as water is essential for every known living organism. The latest data gathered…
