Learn how the molecular movement in different temperature water affects the density of the liquid.

This simulation explores the relationship between the temperature of a gas, the motion of the particles in the gas and the changes in the kinetic energies of particles during collisions.

By the end of this section, you will be able to define diffusion, osmosis, dialysis, and active transport and to calculate diffusion rates.

Examine the link between molecular motion and energy. Observe the movement of a molecule at room temperature. Learn about the different types of molecular motion.

For this lab, students will explore the motion of molecules, the forces involved in making them move and predict the level of interaction that molecules can have in order to better understand chemical reactions.

Work samples, phenomena, assessment templates, and videos that directly address standard MS-PS1-4: thermal energy and particle motion.

In this interactive demonstration, students observe what happens to food coloring when dropped into beakers containing different temperatures of water.

Observe how heating and cooling affect the density of water. Combine the concepts of temperature, molecular motion, and density to learn that hot water is less dense than room temperature water and that cold water is more dense.

This simulation allows students to make observations about the structure and movement of particles in a gas.

This simulation allows students to make observations about the structure and movement of particles in a liquid.

We gain a better understanding of pressure and temperature from the kinetic theory of gases, which assumes that atoms and molecules are in continuous random motion. Learn more about Kinetic Theory with the following detailed resource...

Discover how the molecular make-up of water affects its density.

This simulation allows students to make observations about how particle motion changes as the overall temperature of a liquid changes.

These programs are classical 2-dimensional molecular dynamics simulations. Such simulations compute the motions of atoms by summing (integrating) all of the forces that the atoms exert on each other. These forces arise from changes in...
