Science as Human Endeavour
This post will go through some things to look into for SHE for unit 3 topic 1 of QCE Chemistry.
3.1.8 – Science as a Human Endeavour (SHE)
- SHE subject matter will not be assessed on the external examination, but
could be used in the development of claims and research questions for a
- Chemical balance in wine: The production of wine, along with that of many other food products, relies on the successful control of a range of reversible reactions in order to maintain the required chemical balance within the product.
This video goes through the chemistry of wine.
This video goes through wine chemistry as well.
- Carbon dioxide in the atmosphere and hydrosphere: The oceans contribute to the maintenance of steady concentrations of atmospheric carbon dioxide because the gas can dissolve in seawater through a range of reversible processes.
This video goes through the carbon dioxide cycle.
Acid/Base Models Through Time
- Development of acid/base models: ‘Superacids’, such as carborane acids, have been found to be a million times stronger than sulfuric acid when the position of equilibrium in aqueous solution is considered.
This video goes through acids and bases through history.
This video will go through the models of acids and bases in a little more depth.100
