Catalyst Volume 18 Issue 1
This issue of Catalyst includes the following articles:
Wave Power
To tackle climate change, one potential major energy resource has remained untapped until now: wave power.
Science and Engineering Apprenticeships
This resource describes the different apprenticeships schemes in science and engineering.
TB or not TB
Badgers can transmit tuberculosis to cattle, but is a cull of badgers a solution to the problem?
Hubble Explores a Barred Spiral Galaxy
The Hubble telescope takes dramatic photographs of distant galaxies. But how do scientists know the shape of their galaxy?
QTC - Making the Most of a Novel Material
Quantum Tunnelling Composite is a material whose resistance decreases dramatically under pressure. How does it work, and what uses will it have?
It Must Be True- I Read It in the Paper!
Scientists publish their results in journals, but only after they have undergone peer review.
Hydrogels – Water- Absorbing Polymers
This article explores hydrogels which are polymers with the unusual property of being able to absorb huge quantities of water.
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.
Wave Power
A Catalyst article looking at renewable energy. To tackle climate change and all the challenges imposed by the need to find alternative and reliable energy sources, there is one major resource that has remained untapped until now: wave power. This article describes the size of this resource and presents the leading technological…
Science and Engineering Apprenticeships
A Catalyst article about training as a technician after GCSEs. With an apprenticeship scheme it is possible to start a career at 16, keep learning to acquire qualifications – and get paid. It is quite possible to obtain a permanent job at the end of the apprenticeship. Many different companies up and down the country offer…
TB or not TB?
A Catalyst article about the problems of badgers transmitting tuberculosis to cattle, but is a cull of badgers a solution to the problem? When cattle are found to be suffering from tuberculosis, a disease which can be passed onto humans, they are routinely slaughtered. It is known that badgers can transmit the disease to cattle,…
Hubble Explores a Barred Spiral Galaxy
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 image is just…
QTC - Making the Most of a Novel Material
A Catalyst article about Quantum Tunnelling Composite, a material discovered in 1997 and whose resistance decreases dramatically under pressure. How does it work and what uses will it have? The material has been carefully characterised (to understand its composition and how it works), and its first applications have emerged. In this…
It Must Be True - I Read It in the Paper!
A Catalyst article about scientists publishing their results in journals. Newspapers, magazines and TV programmes are full of stories based on science and technology. But can these articles be trusted? This article looks at the way in which scientists try to ensure that their own publications are reliable. It makes use of a system…
Hydrogels - Water-Absorbing Polymers
A Catalyst article about hydrogels. Soft contact lenses, disposable nappies, hair gel and plant water crystals all make use of substances called hydrogels. These are polymers which have the unusual property of being able to absorb huge quantities of water. The article looks at the structure of hydrogels and their uses; there are…
