A Catalyst article describing how engineers have designed an aircraft which will produce much less noise as it approaches and leaves the airport. The Silent Aircraft Initiative is a collaboration between scientists and engineers at two universities, Cambridge (UK) and the Massachusetts Institute of Technology (USA...

 These materials look at three possible projects that relate to sustainable transport:

* Communications project - students gather information and produce a balanced view on the costs and benefits of using hydrogen as fuel for vehicles.

* Practical project - students investigate the factors that affect...

These materials look at three possible projects that relate to cleaning products and tackling microbes that spread disease: * Communications project - students act as health promotion specialists trying to persuade people about the need to wash hands after using the toilet. * Practical project - students...

These materials look at three possible projects that relate to the bicycle used by an athlete in a triathlon: * Communications project - students gather information and give advice about which bike is suitable for a range of users. * Practical project - students undertake practical experiments to investigate the...

Students research, and then try out, ways of detecting analgesic compounds in mixtures:

• Chemical tests for particular organic functional groups.

• Paper and/or thin-layer chromatography to separate and identify analgesic...

Like ‘The Sims’, in this SimPhysics game students look after a family and keep their home supplied with electricity. In the game scenario the government has set a carbon dioxide quota for each household, so limiting their contribution to climate change. The player has to invest in renewable sources of electricity...

The effective use of the Gravity Jet Suit requires a high level of control, for the pilot, over their core, leg and arm muscles.  This resource explains that biomechanics is the synergy between muscles and bones and shows some of the joints used in flying in the suit.

Produced by Gatsby Science Enhancement Programme, this activity is about information storage and retrieval, about books and journals and about comparing print with electronic information storage.

Students carry out...

Produced by Gatsby Science Enhancement Programme, in this activity students first carry out an Internet search to find websites that would be helpful in answering specific questions about a science topic. They evaluate the usefulness and reliability of different websites. In the second part of the activity,...

This activity, from the Gatsby Science Enhancement Programme, helps students to develop their skills in assessing information. Students consider what they need to look for in an information source to be sure that it is reliable. Students consider the peer review process of a professional journal and compare this...

This activity, from the Gatsby Science Enhancement Programme, helps students to examine the claims to truthfulness of statements of different kinds. The aim is to become more critical of the use of language and to develop a constructive scepticism when assessing primary and secondary information. Students are given...

Produced by Gatsby Science Enhancement Programme, in this activity students look at surveys as an important method of gathering and retrieving information. The activity allows students to evaluate the process of collecting data from short interviews with their peers. It consists of a speed survey game, which is...

These materials, from the Gatsby Science Enhancement Programme, help students to consider the appropriate approach when communicating ideas and information to particular audiences. The activities encourage students to: * analyse information and resources for their level of difficulty, the audience, its reliability...
