Particle Pioneers

An inquiry-driven chemistry sequence for 9th-grade students to master Kinetic Molecular Theory (KMT). Students transition from macroscopic observations of gas behavior to microscopic particle models, exploring pressure, temperature, and diffusion through simulations and creative modeling.

Invisible Motion

Students differentiate between states of matter based on particle spacing and energy, using a perfume 'scent trail' hook to visualize invisible gas motion.

The Big Squeeze

Students investigate the microscopic cause of pressure by observing particle collisions with container walls, using the 'imploding tanker' phenomenon as a core case study.

Heat and Haste

Students explore the relationship between thermal energy and molecular velocity, deriving the Kelvin scale and the concept of absolute zero.

The Great Gas Race

Students model how molecular mass affects gas speed, investigating why different gases travel at different rates through diffusion and effusion.

Gas Theory Realities

Students apply Kinetic Molecular Theory to explain everyday phenomena, like tire pressure changes and expanding chip bags, through a creative comic-strip project.
