REACH and OSH legislations are aiming at the same goal: safety, health and wellbeing of a worker handling chemical substances at work. Terminology and the overall language used within these legislative frameworks differ from each other. At an average European workplace the personnel handling REACH issues or CAD issues may be different. Registrant and a downstream user may have difficulties in communication. In addition to the practical issues causing discrepancies, in a broader perspective, also more profound differences in the philosophy of the two sets of legislation can be pointed out. This has to be understood in order to guarantee proper implementation. A good example of this is setting the European OELs vs. DNELs.... [-]

The International GCSE in Science (Double Award) aims to impart a systematic body of scientific knowledge and facts, and an understanding of scientific concepts, principles, themes and patterns. Experimental skills based on correct and safe laboratory techniques are developed, as well as students’ ability to form hypotheses and design experiments to test them. This single-tier qualification is assessed via three papers – one each from chemistry, biology and physics. Students are awarded two International GCSE grades from A* to G.

This free online course explores a range of chemistry-based topics relating to our everyday lives, with an emphasis on the important role of organic chemistry – the study of carbon-containing organic compounds. Activities include experimenting ‘in the kitchen’ with hands-on projects ranging from extracting a plant fragrance to testing the activity of spices against microbes. The course will be particularly useful for sixth formers who are interested in developing independent learning skills to help the transition to university.

Use real-life examples to study organic compounds

During each week of the course, we will use real-life examples to show you how an understanding of the structure and shape of organic compounds can be used to explain their reactivity and properties.... [-]
