This publication is a report from the Leading Space Education Programme (LSEP). This is a Science and Technology Facilities Council (STFC) funded project that has worked with 30 schools in England with the aim of enhancing science, technology, engineering and mathematics education in secondary schools and using...
This Catalyst article discusses how experiments using the Large Hadron Collider (LHC), which discovered the Higgs boson, at the CERN laboratory can tell us about the nature of matter in the early universe. ALICE (A Large Ion Collider Experiment) is one of the experiments taking place at the LHC. It breaks down...
This Catalyst article investigates the nature of aerogels, which are among the least dense solid materials, not much denser than air. Aerogels were made as the result of a bet and ended up going into space to capture comet dust. They are the lightest solids which exist and have some unusual features.

This Catalyst article presents the work of three chemists - Martin Karplus, Michael Levitt and Arieh Warshel - who won the 2013 Nobel Prize for Chemistry. Their work allowed the development of complex computer models of compounds and reactions.
The article is from Catalyst: Secondary Science Review 2014,...

...This Catalyst article looks at how scientists can use material recovered from archaeological sites to see how crops have been introduced to different countries over the history of farming. Three processes by which some plant material can be preserved are explained. The ratio of carbon isotopes from the collagen in...
This Catalyst article looks at salt, in particular the process of extracting salt from the sea in the salt factories of Trapani in Sicily. Located on the west coast of the island, the saline (salt ponds) were probably started by the Phoenicians around 3000 years ago. The article also looks at the structure of salt...
This Catalyst article looks at NASA's Mars Curiosity rover, the automated chemistry lab which landed safely on Mars in August 2012. Capable of analysing samples from the planet's surface and atmosphere, the rover will undertake two years of experiments in the hope of discovering even more about our neighbouring...
This Catalyst article looks at how the structure and properties of chocolate change when it is melted and re-solidified. An experiment is described in which the differences between solid chocolate, and chocolate which has been melted and re-hardened can be found, along with a detailed explanation of the physics...
This Catalyst article looks at life in extreme environments on Earth which can suggest how life might exist on Mars. One of the developments in recent years that really opened up scientists’ eyes to the possibility of life on Mars has been the realization of just how adaptable and versatile life on Earth is.
...This Catalyst article looks at hydraulic fracking, the process of breaking up rocks deep underground using high-pressure water mixed with sand and chemicals. The process has been used for decades in the energy industry to free oil and gas trapped in rock formations. However, questions have been raised over the...
This article focuses on the practical uses of the element Boron, including its pivotal role in heat conservation, energy conversion and storage....
This Catalyst article looks at how humans are exposed to radiation from many different sources, including food. The article describes the doses of radiation from sources such as:
- building materials and rocks
- bananas
- bone scans
- cosmic rays
- radon gas
The...
As the need to find alternative cleaner forms of energy increases, scientists are looking to technologies, such as Hydrogen Fuel Cells (HFCs), as a power source for transportation.
This Catalyst article explains how hydrogen and oxygen gas can be used in a redox reaction to produce electricity, and the...
