Element, Mixture, Compound

By TeachEngineering -

Students gain a better understanding of the different types of materials as pure substances and mixtures and learn to distinguish between homogeneous and heterogeneous mixtures by discussing an assortment of example materials they use and encounter in their daily lives.

How Small is an Atom?

By Jared Owen -

The size of an atom is only a few angstroms at most - there are 10 billion angstroms in 1 meter. This video also goes the basic parts of an atom (protons, neutrons, and electrons) and why the traditional model of the atom is not correct. Electrons are unpredictible - we can't know the path that they travel. Most importantly - they don't orbit the nucleus.

Sublimation and Deposition of Iodine

By Wayln Breslyn -

Iodine provides an excellent example of sublimation. When iodine sublimes it forms a visible purple gas. When the gas cools it returns directly to the solid phase, an example of deposition.
