Explore and interpret representations of particles, including three-dimensional models, using this lesson plan with activities for 11–14 year olds.

By interpreting diagrams on cards that show representations of particles, students reinforce their understanding of the terms mixture and pure substances (elements and compounds). They explore the use of models, including three-dimensional models, using them to reflect on and develop their own ideas about mixtures and pure substances.
