Moving Air
In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...
Curated OER
Particle Model of Solids, Liquids, and Gases
Display the arrangement of molecules in solids, liquids, and gases. Demonstrate how the addition of heat energy results in greater molecular motion and therefore a change of phase. Give examples of heat conductors and insulators, and...
Curated OER
Diffusion of Molecules
Students conduct a series of experiments to observe factors that impact molecular movement. In this molecular chemistry lesson, students drop food coloring in water with different properties (hot, with ice, with alcohol) and observe how...

Molecular Movement in Water Part 1- Diffusion
Students obseve and compare molecular movement within water at various temperatures and of varying salinity. They discuss the movement of water on a larger scale which can affect the movement and concentrations of microbial populations...
