Through evaluation of a range of data, I can describe the formation, characteristics and uses of soils, minerals and basic types of rocks.
Rocks and Minerals (workshop) – A series of simple experiments to make samples of sedimentary, igneous and metamorphic ‘rocks’.
I can participate in practical activities to extract useful substances from natural resources.
Antioxidants (workshop) – A Range of investigations to look at antioxidant levels in fruits and teas (though the method can be adapted for any antioxidant).
Biodiesel (workshop) – A range of experiments based around the production and testing of Biodiesel from vegetable oil.
Concrete chemistry (workshop) – A series of activities looking at cement and concrete.
Flash Chromatography (workshop) – Flash chromatography carried out in a syringe – using talc (or cornflour) – can be used to separate samples of food dyes or plant pigments.
Lip Balm (workshop) – Activities researching and then making lip balms.
Oil from coffee grounds – not technically an oil but a simple method for extracting an oil-like mixture of terpenoids from coffee grounds that can be used as a fuel.
Shampoo (workshop) – Activity to make shampoo, involving steam distillation to extract natural essences.
Silicon and Silanes from Sand (Demo) – Making silicon and silane from the reaction between magnesium and silicon dioxide (sand).
