Assessment for Learning is an effective way of actively involving students in their learning. Each session plan comes with suggestions about how to organise activities and worksheets that may be used with students.
Observe and interpret the changes when drops of various anion solutions are added to drops of group 2 element cations
Explore the properties of group 1 and 2 by examining whether precipitates form when you add drops of sulphate or carbonate solution to group 1 or 2 metal ions
In association with Nuffield Foundation
On a microscale students add solutions containing lithium, calcium and silver cations to solutions containing fluoride, chloride, bromide and iodide anions, and record which combinations produce an insoluble precipitate. From the results they attempt to identify patterns of behaviour among these anions, and try to explain them.
