GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home.
Triple Award Science, commonly referred to as Triple Science, results in three separate GCSEs in Biology, Chemistry and Physics and provide the broadest coverage of the main three science subjects. The qualifications are offered by the five main awarding bodies in England; AQA , Edexcel , OCR , CIE and Eduqas .
Notes: GCSE grades 9 to 4 (A* to C) – Certificate and qualification awarded. At GCSE, considered a 'standard pass', and awards a qualification at Level 2 of the RQF. GCSE grades 3 to 1 (D to G) – Certificate and qualification awarded. At GCSE, awards a qualification at Level 1 of the RQF.
Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans.
The halogens (/ ˈ h æ l ə dʒ ə n, ˈ h eɪ-,-l oʊ-,-ˌ dʒ ɛ n / [1] [2] [3]) are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors [4] would exclude tennessine as its chemistry is unknown and is theoretically expected to ...
(The Center Square) – A new report from California’s Legislative Analyst’s Office shows that the young adult mortality rate has remained much higher than pre-pandemic levels. “Overall ...
Tourmalines have a very complex chemistry that can be described by a general formula XY 3 Z 6 (BO 3) 3 T 6 O 18 V 3 W. The T 6 O 18 is the basic ring structure, where T is usually Si 4+, but substitutable by Al 3+ or B 3+. Tourmalines can be subgrouped by the occupancy of the X site, and from there further subdivided by the chemistry of the W site.
