Catalyst Volume 22 Issue 1
This issue of Catalyst includes the following articles:
Food Waste Recycling - Power from Potato Peelings
This article looks at how food waste can be treated by anaerobic digestion to produce methane and fertiliser.
Circadian Rhythms
Most organisms have some kind of 'body clock'; scientists are trying to show how genes are the basis of this.
Plant Responses
This article describes how plants respond to many different stimuli including light and gravity, but questions still remain to be answered.
The Sand beneath Your Feet
An article explaining why sand is a fascinating material to explore, and describes what it is made of.
Iron and Alzheimer’s - Studying Metals in the Brain
This article focuses on how X-rays produced by the Diamond synchrotron are used to discover the distribution of iron and other metals in the brain tissue of people who have suffered from Alzheimer's disease.
Bad Science - Patterns, Trends and Dastardly Traps
This article explains the way scientists work, how they conduct their research and look for patterns in data. It also investigates what can go wrong during the process of spotting patterns in the collated information.
Make Your Own Lava Lamp
This article describes how a lava lamp works and what is needed to make one at home.
Where Next?
This article introduces Tom Denbigh who describes how he has worked as a volunteer on scientific projects to gain experience before his degree course.
Volcanoes from Space
Using different wavelengths of radiation, spacecraft have helped scientists to understand more about volcanoes.
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.
Food Waste Recycling - Power from Potato Peelings
This Catalyst article describes how food waste can be treated by anaerobic digestion to produce methane and fertiliser. This article is from Catalyst: GCSE Science Review 2011, Volume 22, Issue 1. Catalyst is a science magazine for students aged 14-19 years. Annual subscriptions to print copies of the magazine can be purchased…
Circadian Rhythms
This Catalyst article looks at how an internal biological clock within every cell of the human body helps to co-ordinate and organise human behaviour and metabolism into approximately 24-hour rhythms – allowing organisms to synchronise with, and anticipate, day and night. When the body clock is disrupted in humans it can have…
Plant Responses
This Catalyst article explains how scientists came to understand plants' sensitivity to external stimuli and their ability to move. Mimosa pudica is a good example of a plant which folds its leaves in response to touch or heat. However, the folding movement of the leaves is very unusual and not found in many other plants. In…
The Sand Beneath Your Feet
This Catalyst article explains how studying sand can reveal both the geological and biological history of a local environment as sand varies from place to place. Sand from near a copper smelter can contain grains of copper; grains can contain worm trails from microscopic worms living in the ocean. Even the grains themselves can contain…
Iron and Alzheimer’s - Studying Metals in the Brain
This Catalyst article looks into Alzheimer’s disease which affects around 465 000 people in the UK, with the number of sufferers is growing as the population ages. It is a form of dementia that causes cell death in the brain and leads to memory loss and mood swings. The article investigates whether the presence of iron in…

This Catalyst article explains the way scientists work, how they conduct research and look for patterns in data. It also investigates what can go wrong during the process of spotting patterns in the collated information. This article is from Catalyst: GCSE Science Review 2011, Volume 22, Issue 1. Catalyst is a science magazine…
Make Your Own Lava Lamp
This Catalyst article describes how to make a lava lamp by using three simple ingredients: vegetable oil, food colouring and fizzing tablets. The article also explains the processes taking place inside a real lava lamp and why they happen. This article is from Catalyst: GCSE Science Review 2011, Volume 22, Issue 1. Catalyst…

Volcanoes from Space
This Catalyst article describes how the distribution of volcanoes across the Earth’s surface tells scientists about the underlying pattern of tectonic plates. Much can been learned about volcanoes by observing them from orbiting spacecraft. This article is from Catalyst: GCSE Science Review 2011, Volume 22, Issue 1. Catalyst…
