Diagramatic representation of the replication of DNA. This is the process by which the cell makes a copy of its existing DNA before it divides. This therefore ensures that each new cell receives a full complement of DNA. The DNA polymerase enzyme can only add new bases in the 5'-3' direction. This leads to...

In this method, the DNA is used as a template to generate a set of fragments that differ in length from each other by a single base. The fragments are then...

This animation, from the Wellcome Trust, illustrates how the DNA code is used to build protein molecules inside our cells.

It shows how, during the process of transcription, polymerase unzips the DNA and uses it as a...

This video journeys into the human cell revealing DNA.

A collection of resources covering DNA, genes and chromosomes. This collection is part of the Post 16 genetics and genomics collection.

This book and accompanying teacher guide focus on the story of a young girl and her passion for saving water. The story follows the journey of an ordinary schoolgirl in the UK, who transforms into a water superhero when a DRY summer is followed by a DRY winter. The teacher guide provides eight linked activities...

This is one of the 18 Background Books published for Stage II of the Nuffield Chemistry Sample Scheme. The books were highly illustrated and designed to be attractive. This book describes early thinking about atoms that led, in time, to modern chemistry.

There are two parts to this book:
*Part 1: The...

This resource provides a lesson plan showing how a history-based approach can be used to teach a simple Dalton atomic model.

The research summary suggests a history-based approach improves pupils' understanding of atomic theory. Elements of this research are utlised within the lesson plan to show how and why...

This Problem Solving with Industry module was devised by the Centre for Science Education in collaboration with Yorkshire Water. In this module students study the problem of blue-green algae in an upland reservoir.

The engineers behind the Watt Nightclub in Rotterdam turn the energy created by clubbers on the dance-floor into power for the lighting. There is even a giant battery to monitor the energy and encourage the crowd to dance more. These resources look at how colour can affect mood and at how electric power can be...

This activity gives SEND pupils the opportunity to make up a dance routine and create a clear algorithm for a partner to follow. Pupils will learn to follow instructions, create a sequence of instructions for people to follow and to understand that the order of instructions is important. Dance move cards will...

This worksheet provides a picture of a skeleton for children to label by choosing the correct word from the list. The activity can be completed after watching the video Tiana...

This activity comes as a presentation, aimed at using an engaging material to probe the children's thinking, reasoning and scientific talk skills. Asking questions such as: ‘What happens when you mix cornflour and water?’, and ‘What could be causing it to move in this way?’ It provides an opportunity to get the...
