From the Wellcome Trust Sanger Institute, these resources will help students to understand the processes involved in the sequencing of DNA and the Human Genome Project. Animations illustrate: * The Human Genome Project (HGP) * DNA sequencing * Producing DNA libraries * Subcloning of DNA The information is quite...

The first human in space was Yuri Gagarin. Since then, humans have 'walked' in space, set foot on the Moon and lived for long periods in orbit on craft like the International Space Station (ISS). This collection contains images, video and other resources that show how humans have explored space.

A high degree of balance is required to successfully fly the Gravity Jet Suit.  This resource explains how our balance is controlled in our inner ear and vestibular system.

This resource is based on the Inventive podcast. The podcast mixes engineering fact with fiction. Each podcast features an interview with an engineer. In this activity, electronics design engineer Shrouk El-Attar is the inspiration for Tania Hershman to write 'Human Being as Circuit board, Human Being as Dictionary...

This website contains a range of human-centered design methods created by IDEO and shared through their online Design kit. The Design kit provides step by step...

A Catalyst article about Hurricane Katrina which caused many deaths in August 2005, and vast damage along the coastline of the Gulf of Mexico in the USA. Hurricanes are an unfamiliar phenomenon here in the UK. Why is this? And can people expect to see more hurricanes in future as a result of climate change? The...

A Catalyst article about hydrogels. Soft contact lenses, disposable nappies, hair gel and plant water crystals all make use of substances called hydrogels. These are polymers which have the unusual property of being able to absorb huge quantities of water. The article looks at the structure of hydrogels and their...

As the need to find alternative cleaner forms of energy increases, scientists are looking to technologies, such as Hydrogen Fuel Cells (HFCs), as a power source for transportation.

This Catalyst article explains how hydrogen and oxygen gas can be used in a redox reaction to produce electricity, and the...

Diagram showing the hydrogen bonds that form between the four bases in the DNA double helix. These weak forces between the bases keep the two complementary strands of DNA together and ensure that the correct bases are put in the right place during replication of the DNA molecule. A always pairs with T and C always...

This practical activity outlines how to grow plants hydroponically in the classroom. It aims to give students an understanding of the basic growth needs of plants. It also shows how hydroponics can be utilised to provide food to humans as our population expands.

This technique can be expanded in a number of...

A hyperbola is given with a parabola ax²  touching each branch of the hyperbola at single points. The task is to determine the value of a.

A formal proof of the general situation involves substituting the equation of the parabola into the equation of the hyperbola. The...
