Cutting vehicle pollution - school science resource

Johnson Matthey has recently updated this introduction to autocatalysts and exhaust management, its most popular download aimed at schools. Presented as a 24-page written report produced by a student (Otto Catalyst), this free resource introduces the chemical components of vehicle pollution (carbon monoxide, hydrocarbons, nitrogen oxides and particulate matter), their impact on the environment and human health, and approaches to reduce emissions from vehicles powered by gasoline or diesel. The autocatalyst and its role in a catalytic converter is explained, showing how the autocatalyst works to reduce gasoline engine emissions. Diesel engine emission reduction, by using particulate filters, coupled with selective catalytic reduction systems or adsorber catalysts to remove nitrogen oxides, is also covered. 

BestChoice virtual learning environment extends to GCSE science

This is the University of Auckland's online chemistry virtual learning environment (VLE). Launched in September 2007, the website's content focuses on A-level and first-year undergraduate chemistry. With support from the Royal Society of Chemistry (RSC), the VLE is available to students studying A-level and International Baccalaureate chemistry free of charge.  

The VLE is designed to support the use of formative assessment to enhance students' learning of chemistry. As students study a topic they are faced with interactive exercises (multiple-choice questions, A-level-style structured questions etc) which test their understanding and provide instant feedback to support their learning. Students' performances are recorded in the VLE's database, Bestchoice reports, which teachers can access to follow their students' progress.  

Encouraged by the reaction of students and teachers, the content of the site is currently being extended to cover GCSE specifications. In September 2009 a core GCSE syllabus will be available to students. To help students identify material and assessment questions relevant to the course they are studying, the content will be marked as appropriate for double award science, additional science and separate chemistry GCSE specifications.
