This Catalyst article looks at the Rosetta mission: to rendezvous with Comet 67P/Churyumov-Gerasimenko where it will study the nucleus of the comet and its environment for nearly two years, and land a probe on its surface. The article also describes how gravity assists, also known as slingshot manoeuvres, are used...

This Catalyst article looks at analytical chemists, who are involved in many kinds of testing, including drug testing to catch cheats in sport.

Produced by Science & Plants for Schools (SAPS), this investigation looks at the activity of the enzyme catechol oxidase (also called polyphenoloxidase). Found in a wide variety of plants, it is responsible for the darkening observed when many fruits or vegetables...

Working in a school without a physics specialist, Catherine contacted STEMNET for help with meeting the specifications of a new curriculum. As a result, the school gained help from a STEM Ambassador who not only explained particle physics in an accessible way but also showed how exciting careers in physics could be...

This very short video demonstrates the experiment that led Thomson to conclude that all atoms contain electrons and helped him to create his ‘plum pudding’ model of the atom.

This video introduces a reliable technique to demonstrate tissue culture and totipotency, and shows how best to use this protocol with your students.

Unlike animal cells, many plant cells are totipotent, meaning that...

This collection of resources was devised and published by Association for Science Education (ASE) in the last decade of the twentieth century to celebrate the centenaries of a number of key discoveries in the history of science.

Produced in 2014, this resource looks at cell signalling when the hormone adrenaline binds to receptors on the surface of the target cell. The resource sheets describe how the original hormonal signal is amplified through a cascade reaction.

The resources in this collection cover teaching about cells for students aged 11-16.  They were produced to enrich a visit to the Intech Science Centre, but can be used independently of a visit.

Cell! Cell! Cell! is the story of the trillions of cells that form our bodies, from our beginnings as a...

This booklet contains a range of suggested teaching activities and contexts for teaching about cell division, cell diversity and cellular organisation at A level.  Topics covered include: cell cycle, mitosis, meiosis, tissues, organs, differentiation and stem cells.

Although produced to support the teaching...

This teaching guide provides a range of ideas and resources for teaching about cell structure at A level. Curriculum links include cells, microscopy, organelles, cytoskeleton, prokaryote and eukaryote cells.

Although produced to support the teaching of OCR AS and A Level Biology A specifications (H020 and ...

The Cells sub-collection is made up of pedagogical guidance and classroom materials for use with students. All materials were published by the Key Stage Three Strategy and the Secondary Strategy between 2002 and 2003.
