Produced by the Royal Observatory Greenwich, this booklet shows how to use Kepler’s third law to calculate the mass of the black hole in the centre of the Milky Way. Included is an online video that discusses what is inside a black hole. Equations and physical terms are introduced and discussed. Students are tasked...

Chemists analyse the tiny traces of substances which form a fingerprint. This allows them to determine drug abuse and as well as the age, gender and diet of an individual.

This resource presents some real seismic data recorded before a volcanic eruption and allows students to locate some of the resulting earthquakes by use of graphs and maps.

This video demonstrates how compressing a gas increases its temperature. A small piece of cotton wool is placed into the bottom of a narrow plastic tube. When the air is rapidly compressed by a piston, the air temperature increases and the cotton ignites. The 'fire piston' can be used to illustrates the transfer of...

This Catalyst article looks at fireworks and their history, how they are made and set off, and what gives them their colours and effects. The basic chemistry used in fireworks is looked at and how they work once the fuse is ignited.

A Catalyst article about the Wright brothers who made the first powered flight. Unlike the try-it-and-see methods used in many of the previous attempts, the Wrights approached the problem of flight in a scientific way and beat the competition. This article looks at the Wright brothers' research and the wing shapes...

This Science upd8 resource draws on research showing that the child raised as the eldest in a family is likely to have a higher IQ than their siblings.

The reasons for this advantage are not yet clear. In this activity students come up with creative explanations and plan how to collect evidence to test them...

This podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC) looks at how the famous White Cliffs of Dover could be made of fish poo (at least partially), why one researcher is so interested in dead whales, and why the Japan earthquake was so powerful and devastating....

In this video, Matt describes how he became a fisheries technical officer for the Environment Agency. His job is to monitor river habitats and fish populations, including improving the habitat and restocking fish after any pollution incidents.

The video could be used to introduce units of work including...

This Catalyst article describes how fish can help scientists to learn more about human biology. Understanding how human bodies work and what causes human disease is the key to future medical breakthroughs. Most discoveries in medical science are a result of experiments that cannot be performed on humans. Animal...

This resource, produced by SEPNet and Queen Mary University of London, uses Lego to represent the building blocks of matter. Different colour and size Lego bricks are assigned to protons, neutrons and electrons. Fusion is shown by joining bricks together and fission by breaking large collections of bricks apart....

From The Centre for Industry Education Collaboration (CIEC), these activities look at the question of drinking water quality.

The activities examine the issues involved and looks in detail at ways of removing nitrates from drinking water supplies. Both water treatment and agricultural solutions are...

In Flesh Eaters, provided by the Association for Science Education (ASE), students are challenged to unravel a bizarre crime using their scientific skills.

Flesh Eaters is a 'learning adventure'. It combines computer-...

This Catalyst article explores 'Biomodels', biological species which are increasingly well-understood and which have been chosen because they can help us to test new biological theories, particularly in the field of genetics.

This article is from Catalyst: Secondary Science Review 2011, Volume 22, Issue 2....
