Jellytotium - base concepts and jelly tots

Planned a lesson around the concept of relative atomic mass for Grade 10. We decided that we need to take time to explain basic concepts very well in order to facilitate a speedy grasp of later more difficult concepts. Illustration of the concept will cover one period. The class as a group will have to determine the relative atomic mass of an imaginary element “Jellytotium”. We planned the lesson around the use of jelly tots and determining the relative atomic mass with an electronic scale. The social curriculum will be addressed as the whole lesson will be group work and formative assessment will be done in the form of written and verbal questions. There will not be any differentiation as this is the first introduction of a base concept. In the follow-up lessons more attention will be given to differentiation and individual work.
