Product Description
In this 3-lesson unit plan, students will develop a particle model of matter, and use it to explain changes of state, observations of compression, expansion, dissolving, and evaporation.
This unit is accompanied by a student Workbooklet. The booklet is designed to allow students to personalize the front and back pages. All homework and classwork is presented in this Workbooklet, which also comes with a student self assessment form for students to take ownership for their own learning. The lesson plans provide instructions on when and how to use this booklet within the lesson.


In Lesson 1—the students develop the particle model of solids, liquids and gases through drama and role-play. They then use this to explain compression and expansion of gases through tangible simulations.
In Lesson 2—the students observe dissolving of a solid (salt) in water and use the particle model of matter to explain this observation. They then carry out an investigation on dissolving salt in water at two different temperatures. They also learn to examine a set of data collected on dissolving sugar at different temperatures of water, and graphically represent it and draw conclusions.
In Lesson 3—students explain evaporation through the use of the particle model, and further investigate the conditions resulting in the speeding-up of the process.
