This is a simple investigation where you connect a Geiger Muller tube to a variable voltage supply. You then place an alpha source in front of it and record the count rate for a variety of supply voltages to see how this impacts the count rate.

A Catalyst article looking at how gel electrophoresis is used in DNA fingerprinting. Gel electrophoresis is used to separate big molecules, in particular nucleic acids and proteins. To learn more about the structure and function of large molecules such as DNA and proteins, they can be broken up into smaller...

Produced by Science & Plants for Schools (SAPS), this activity enables students to look at the gel electrophoresis of DNA treated with restriction enzymes. It will help to develop a knowledge and understanding of the cutting of DNA with restriction enzymes.

Gelli Baff, a crystalline powder, has been dumped into a bathtub filled with water. How can you force the hydrogel to go down the plughole in order to drain the bathtub? 

In this investigation, students learn about swelling reactions, balanced reactions, and polymerisation. Students should be able to...

From Nelson Thornes, these activities encourage students to consider the processes involved in gene therapy. Students are presented with an article about a method of gene therapy that uses artificial chromosomes before answering a set of questions comparing this method to more traditional techniques and the...

This resource looks at the development of genetic modification, genome editing and CRISPR, and where these technologies might lead. 

New genetic engineering technologies offer exciting opportunities to speed up the traditional plant breeding process and generate high-yielding, disease-resistant, climate...

Generation Logistics is an initiative from the Chartered Institute of Logistics and Transportation to demonstrate to students and teachers the relevance of the logistics industry to their lives and the wide variety of career opportunities available.

The resources contained within this collection apply real-...

Mind-boggling progress has been made in our ability to sequence a genome accurately and quickly, and in our ability to process and understand the huge amount of data that sequencing produces. What do these developments mean for each of us – our health, our identity, and the world we live in – now and in the future...

A 3D movie that journeys into the human cell revealing a gene.

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine.

In recent years, great progress has been made in genome sequencing and understanding the huge amount of data produced....

This article on Genetic Databases appeared in Biologist magazine in 2001. The resource is provided by the Association for Science Education (ASE).

What we eat; how we function (even to the smallest active molecule); every creature, microbe or plant that lives and grows in, on and around us - all these...

Produced in 2015, these resources look specifically at how genes can be altered in plants and how bacteria are central to genetic engineering techniques. Genetically modified (GM) crops offer the potential to help improve food security though this still remains...

Produced for the Citizen Science project, this resource enagages students in the debate around genetic testing and screening. It is suitable for students aged 14-16 and post-16. The activity provides an opportunity to investigate genetic disorders before considering a number of statements and situations concerning...
