Hydrochromic Paint
This short film from the Technology Enhancement Programme (TEP) is one of a series of clips which were produced to demonstrate the properties and use of a range of smart materials.
This paint can be applied as standard paint and appears semi transparent. Once dry, the paint appears as a solid white colour;...
Hydrogels - Water-Absorbing Polymers
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...
Hydrogen - Exploding Eggs
From the Teachers TV series Demonstrating Chemistry, this demonstration shows how a mixture of hydrogen and air becomes explosive. Professor Hal Sosabowski evacuates an egg by drilling two holes and using an airline to blow the egg out. He flushes out all the air from the egg before filling it with hydrogen. With...
Hydrogen and Oxygen
In the build-up to the Christmas Lectures in 2012, the Royal Institution published a new video for every day of advent revealing the elements that really excite and inspire people. Demo developer and science presenter Fran Scott has two favourite elements: hydrogen and oxygen. She demonstrates the explosive...
This item is one of over 25,000 physical resources available from the Resources Collection. The Archive Collection covers over 50 years of curriculum development in the STEM subjects. The Contemporary Collection includes all the latest publications from UK educational publishers.
Hydrogen as an Energy Carrier
From The Centre for Industry Education Collaboration (CIEC), these activities look at hydrogen, its preparation by electrolysis and its potential as a transportable fuel.
In the activities, students:
- Study the properties of hydrogen in order to evaluate it and identify the technological problems...
Hydrogen bonding
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...
Hydrogen power
This activity from a series of resources looking at the future of flight from the IET, explores making hydrogen from water, which is the basis of hydrogen fuel cell technology. Hydrogen is an alternative to petrol and diesel fuels for combustion engines and the only byproduct of using it is water, so it does not...
Hydrogen Powered Cars
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...
Hydrogen Rockets
From the Teachers TV series Demonstrating Chemistry, this video shows how to carry out an exciting demonstration which illustrates what happens when hydrogen and air react. Professor Hal Sosabowski, from Brighton University, uses an explosive mixture of hydrogen and air in a plastic bottle to show how rockets...
