A Catalyst article describing how new materials can be designed by studying natural materials and how they work. In particular the development of Velcro, military fabric, swimwear and waterproofing is looked at. These products were developed by scientific study of natural products such as plant burrs, pinecones,...

This Catalyst article investigates biomimetics and discovers how scientists are finding ways of copying ideas from nature to improve products. The article is from Catalyst: Secondary Science Review 2015, Volume 26, Issue...

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, this factsheet illustrates the benefits of using bioplastics, their production, properties and uses. The attraction of bioplastics is they deliver environmental benefits even when they aren’t biodegradable. Durables like polyethylene terephthalate (PET), polyethylene (PE)...

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.

This Nuffield Working with Science unit aimed to draw on the popularity of bird watching to develop skills of observation and investigation.

Guidance for teachers and technicians appears in...

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...

In this activity the goal is for students to understand how the regression line is chosen. Autograph has a built-in facility for showing the squares of the residuals and is required to make this task work. Students are asked to explore what the lines that give the sum of the y-on-x residuals equal to zero have in...

In this activity, students are challenged to produce a scatter diagram consisting of ten points that give a product moment correlation coefficient of exactly 0.99. Students are expected to appreciate that the points will lie almost exactly on a straight line with at least one point being slightly out. The answer...

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...
