A Catalyst article looking at the use of plant cells to generate electricity via photosynthesis. This branch of science is called biophotovoltaics. The Sun is the ultimate source of energy for almost all life on Earth and harnessing this energy is one of the great scientific and technological challenges....

From the National Non-Food Crops Centre (NNFCC), these two podcasts explore a range of applications and issues in the biorenewables sector. They are primarily aimed at a commercial audience but may be of use to teachers who want to gain a better understanding of plant-derived materials or, when used in part, as...

This poster illustrates how biotechnology is used to develop new medicines, grow new tissues and organs, and genetic testing.

A cluster of practical activities for students to explore biotechnology involving viability of yeast, fruit juice production, milk products, fungal inhibition and microbial growth curves.

The Birmingham Institute for Forest Research (BIFoR) is home to the BIFoR FACE facility, one of the world's largest climate change experiments where 150 parts per million extra of carbon dioxide is added to areas of the oak forest, to predict the impact on the ecosystem 50 years into the future.

BIFoR has...

This Catalyst article describes how, as two tectonic plates separate, wide fissures appear in the ground in northern Ethiopia. Eventually a new ocean will form in the area affected. The Earth’s surface is not stable or permanent. The tectonic plates that form our planet’s outer crust are constantly moving around,...

This Catalyst article looks at orchids, their breeding, and why they have great commercial value. The family of Orchidaceae is one of the largest plant families, with about 900 genera and 25,000 species. Orchids are amongst the oldest flowering plants. After a long evolution, they have developed a very intimate...

Produced by Twig, this animated video is a clear and accessible explanation of how the Solar System fromed. The video describes how:

* the solar system grew from a ball of gas which formed the Sun

* gravity caused heavy material to cluster together and eventually form planets

* the inner...

This Core Maths resource includes data from which students can calculate correlation coefficients. The resources includes a card sort that matches up scatter-graphs, data tables and product moment correlation coefficients. 

The teachers' notes give detailed teaching suggestions on how to introduce and...

Black holes provide an important tool for testing the fundamental laws of the universe. This resource from the Institute of Physics, looks at the extreme physics associated with black holes, how we can spot them, and what roles they may play in galaxy formation.

This guide looks at stellar black holes and...

These career profiles provide information on the wide range of people involved in the Black Sea Maritime Archaeology Project (...

This video and classroom task explores how the crew of the Black Sea Maritime Archaeology Project (@BlackSeaMAP...

This article explores the relationship between black holes and gravitational waves.

Catalyst is a science magazine for students aged 14-19 years. Find out more about Catalyst magazine: www.stem.org.uk/catalyst

This Catalyst article explains how chemists build molecular 'traps' to mimic the surface of a cell. To scientists, sugar is much more than a food; sugar molecules can also form polymers which act as ‘molecular bar codes’ to help cells recognise each other. The article describes how chemists made a synthetic...
