A Catalyst article looking at how insects are used to provide clues at crime scenes. Forensic entomology is the study of insects and other arthropods in a legal context. It covers many different areas, such as pests in stored food products and insect infestations in human habitations. However, the most high-profile...

This book looks at several aspects of forensic science: * Dusting for fingerprints * Fingerprints in blood * Fingerprints on difficult surfaces * Shoeprints * Making casts * Comparing soil samples * Heating and burning soils * Forgery * Bloodstains Forensic Science was one of the Science at Work series. All the...

A Catalyst article about careers in forensic science covering the work of the reporting officer. The article explains what it takes to become a forensic scientist and what qualities are required to join this profession.

This article is from Catalyst: GCSE Science Review 2005, Volume 16, Issue 1.

A Catalyst article about scientists who are only beginning to understand just how complex and fascinating the relationship between trees, the carbon cycle and climate really is. This article explores how aspects of the GCSE science course relate to the latest research. It also covers the relationship between trees...

In this activity students use their STEM skills to transform a room in their house or garden. They  will be measuring, drawing to scale and choosing items to remodel. Thinking carefully about dimensions, materials and how to present their new design, students will be practicing measuring and drawing to scale...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Categorise everyday observations of change.

• Distinguish examples of physical change from chemical changes.

• Explain observations of a chemical...

This resource, from the Royal Observatory Greenwich, discusses a range of topics about how the Sun, planets, asteroids and/or moons have been formed over millions of years.

This activity is based on the work being carried out at The University of Oxford where researchers are using x-ray tomography (CT scanning) to visualise and measure the 3D structures of fossilised organisms that are still encased in rock.

A STEM club activity where students become a junior palaeontologist and create their own replica of a fossil from the Jurassic period, learning the conditions necessary for fossilisation.

This fact sheet for primary pupils explores what fossils are and how they form. It considers why scientists study fossils and what can they tell us about the ancient creatures and plants that once lived on Earth.
