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...
Details of this challenging experiment were published in this leaflet from the Unilever Laboratory Experiment in 1965. Requirements included a pyrophoric nickel catalyst supplied by Unilever, hydrogen from a cylinder and a vegetable oil treated with activated charcoal to remove impurities. The necessary apparatus...
Hydroponics
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...
Get a 360° view of growing plants from the roots up! Unique, transparent seed baskets provide a view of seedlings growing both up and down. Water in the plastic tubes creates an...
