17 Earth’s materials
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.
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.
Concrete chemistry (workshop) - A series of activities looking at cement and concrete.
Lip Balm (workshop) - Activities researching and then making lip balms.
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).
I have explored how different materials can be derived from crude oil and their uses. I can explain the importance of carbon compounds in our lives.
