This short video teaches students how atoms are the smallest particles of elements and how each element is comprised of one type of atom.

Burning Steel Wool

This video shows shows students how burning a piece of steel wool leads to an increase in mass.

Reusable Heat Packs

This video clip shows students how bond energy is released in a chemical reaction when a sample of sodium acetate is activated from touching a metal disc on the plastic of the heat pack.

Balancing Chemical Equations

In this simulation, students balance chemical equations using scales to show balance on sides of reactants and products. There is also an extension link for additional practice problems for students to predict products of chemical reactions.

Periodic Trends

In this hands-on activity, students create a 3-D model of the Periodic Table using sticks of spaghetti to observe the trends in atomic properties that underlie the arrangement of elements into periods and families.

What is Temperature?

This article teaches about the basics of temperature and how it relates to average kinetic energy of particles. The article uses snow as an example so that students can note the phenomena of falling and melting snow on the ground.

Metallic Bonding

This simulation allows students to see the electron movement between metal atoms and thus how a metallic bond forms. Students can also investigate the properties of the electron movement by changing the temperature of the metal.

Heat of Fusion

This video teaches students to learn a song to remember what fusion is and how it relates to freezing. Phase diagrams are also explored to teach how potential and kinetic energies change during phase changes.

Phase Changes

This video and simulation has students observe what happens to particles when an ice cube melts or when water boils. Emphasis is placed on particle movement with changes in temperature.
