Looks at the history of atomic theory and ideas about atomic models that have evolved over time. Covers models put forward by John Dalton, J.J. Thomson, Earnest Rutherford, Niels Bohr, and the work of Schrodinger and Heisenberg. Also discusses photons and the photoelectric effect. [16:12]

Students are introduced to the similarities and differences in the behaviors of elastic solids and viscous fluids. Several types of fluid behaviors are described Bingham plastic, Newtonian, shear thinning and shear thickening along with their respective shear stress vs. rate of shearing strain diagrams. In addition, fluid material properties such as viscosity are introduced, along with the methods that engineers use to determine those physical properties.

This article assembles free resources from the Water, Ice, and Snow issue of the Beyond Penguins and Polar Bears cyberzine into a unit outline based on the 5E learning cycle framework. Outlines are provided for Grades K-2 and 3-5.

Abby Brown, KIDS Clubhouse Adventures co-host, loves to help kids have fun while learning! In this segment, Abby teaches kids about metal. Kids learn about common properties of metal, and why glass, wood, and plastic are very different. Kids also learn how some metals are used. [2:04]

This video/animation defines matter, mass, and volume using water as an example. The size, electrical charge and location of the subatomic particles of matter are described. Different types of atoms are called elements and organized in the periodic table. What happens to the properties of atoms when they exist alone or together? [1:16]

In this Science 101: What is Quantum Mechanics video, Katherine Harmon - Argonne Scholar in the Materials Science Division - explains what quantum mechanics is.

This video/animation shows that a molecule of water is made up of oxygen and hydrogen atoms. When oxygen and hydrogen atoms exist alone, their properties are different from the properties they have when they are chemically combined to form a water molecule.
