SUMMER SCHOOL, DAY 3: "CHEMISTRY, THE BASICS"
Parts of this video were shown in class on July 15th, a day that Mr. Hatfield was out of class and students had a substitute teacher.
The sections of the video shown in class dealt with measurement (metric system, significant figures) and stoichiometry. I'm making this available here so anyone who was absent that day can review it, or (if present) watch it again. These topics will crop up on a weekly basis for most of the year.

SUMMER SCHOOL DAY 2, VIDEO: COSMIC VOYAGE
Summer School students viewed a 36-minute IMAX video in class on Monday and Tuesday, and should've already completed a worksheet based on part of the video. The film, 'Cosmic Voyage', was made in 1996 for the Smithsonian Institute and was clearly inspired by a classic science education film called 'Powers of Ten', originally produced in 1977 by the husband-and-wife team of Rae and Charles Eames.
'Cosmic Voyage' approaches the idea of using the metric system, which is based on powers of ten, to explore the question: "What is really large, and really small?" The film first zooms out from an acrobat's ring in St. Mark's Square in Venice, the place where Galileo first trained his telescope on the heavens.
Through 23 powers of ten, we leave first the Earth, then our solar system, then the Milky Way Galaxy behind, until we reach the limit of modern astronomy, where we can see images from about 13 billion years past.
Reversing course, the video then zooms in on drop of water in the Dutch town of Delft, where Antonie Van Leuuwenhoek first trained his early microscope to discover the hidden world of microbes.
As we zoom in on a paramecium, we penetrate its cell nucleus, then zoom in on a molecule of DNA.
Within that molecule is a carbon atom, and the world within that atom is mostly empty space! Within the atom, the atomic nucleus contains virtually all of an atom's mass, made of particles called protons and neutrons. These, in turn, are formed from even smaller particles called quarks.
The film continues with a discussion of the search for a fundamental theory in physics through the use of particle accelerators like Fermilab, along with an overview of the likely "recent" events that led to our sun, our solar system, the Earth and life itself.
Here, presented on YouTube, is the first segment (Chapter 1) of the film who wish to review the material or share it with others. As the narrator (Morgan Freeman) intones, 'we are all travelers on a voyage of discovery!' Chapter 2, and Chapter 3 can be assessed at YouTube directly or by clicking on the hyperlinks

SUMMER SCHOOL, 1st SESSION: FIRST DAY
The first set of Notes for Mr. Hatfield's Summer School Chemistry Class are now available on-line, here:
The topics of the notes include the relation of chemistry to mathematics and other sciences, what makes chemistry distinctive in terms of its content and practice, the nature of science, scientific method ("O.H.E.C.K."), atomic theory and the periodic table.
Students should download the Power Point Notes to make sure that their notes are complete, as from time to time their composition books containing their notes will be inspected and graded.
Below is an outline of the 11-day session:

POWER POINT: CARBON, THE SHAPE OF LIFE

ORGANIC CHEMISTRY VIDEOS
In Monday's class, we talked about the difference between organic (based on carbon) and inorganic (based on some other element) molecules. Life, of course, is based on organic molecules.
We explained that there are four major classes of carbon-based compounds used by living things: carbohydrates, lipids, proteins and nucleic acids.
Each of these compounds is made of individual 'building blocks' called MONOMERS. The monomers are linked together with covalent bonds to make large chains called POLYMERS, and the process of making polymers is referred to as POLYMERIZATION.
Here's a video from Bozeman Science, with animations, that gives some nice background on monomers and polymers:
Carbohydrates are carbon-based macromolecules based on C, H and O. They are polar and readily dissolve in water.
A simple sugar by itself, like glucose, is termed a monosaccharide, and serves as a 'building block' (monomer) to build a larger chain of many molecules called a polymer. In the case of carbohydrates, the polymer made from many monosaccharides linked together by dehydration reactions is called a polysaccharide.
Examples of polysaccharides made of glucose include cellulose, glycogen and starch. Each of these glucose polymers are biologically important.
Finally, here's yet another video by AP Chemistry teacher Paul Andersen, this on the class of macromolecules called PROTEINS.
PROTEINS often are used to build extremely useful and specific molecules called ENZYMES:
