The PowerPoints you download are good for review. But most do not have a narration or captions. To see animations, you need PowerPoint 2002 (from Office XP) or PowerPoint 2003 (from Office 11) or download the Windows PowerPoint viewer (click here for viewer 1.86 Megs). The new Office for Mac should work, but I haven't test it yet.

To Download click with right mouse button and choose "Save Link Target as..."  However, if you just click on the link and have PowerPoint on your computer, the presentation may start downloading in the background (no message) and it might take awhile before you see the PowerPoint presentation popup.

IT'S ALL ABOUT BUILDING BLOCKS: Chemistry is made simpler when you realize it is all about building blocks. You can download PowerPoint this is sometimes shown in class, but you will get more explanation going through the six online tutorials listed below. This is also a homework assignment. Go to homework page.
Building Block PowerPoint (6.4 Megs)
1. Building Block Intro
2. Protons, Electrons, and Neutrons Built from Energy
3. Elements Built from Protons, Electrons, and Neutrons
4. Compounds built from Elements
5. Building Blocks for Inorganic Compounds
6. Building Blocks for Organic Compounds 

EARLY USES OF CHEMISTRY:
This presentation was used to explain why chemistry became a science. It's based on our need to survive. Below is a link to the PowerPoint used, but you will get the written narration if you go to the tutorials for this subject following the links below.Size is 8.4 Megs: Click here to download PowerPoint

Early Uses of Chemistry Web Tutorials:
Stone Tool Technology       Clay Chemistry     Preservation of Food

WHAT'S IN A NAME?
(Nomenclature: non-metal to non-metal, i.e., binary covalent compounds)
This PowerPoint is a tutorial on how to name non-metal binary compounds. For example, carbon dioxide is a non-metal binary compound. Carbon and oxygen are non-metals. This one is shown in class but is good for self learning. To download click here (1.8 Megs).

WHAT ARE IONIC COMPOUNDS?
(Nomenclature preparation)

This PowerPoint explains what "ions" are plus helps in understanding the charges that atoms have. This knowledge is useful in naming ionic compounds. Download (629 K).

NAMING IONIC COMPOUNDS

This PowerPoint gives details on naming ionic compounds. Ionic compounds made from two elements (binary compounds) and those that use polyatomic ions are covered. Download (915 K).

POLYATOMIC IONS & WHERE THEY ARE FOUND

This PowerPoint shows how polyatomic ions are related to binary covalent compounds (e.g., non-metal gases). Lewis structures are used to help explain the charge on the polyatomic ions. Where you see compounds with polyatomic ions is also covered.
Download (2.5 Megs).

NAMING AQUEOUS ACIDS AND THEIR SALTS

This PowerPoint gives details on naming acids based on their salt name. This covers both binary acids (e.g., HCl, HBr) and ternary acids (e.g. HNO3, H2SO4, etc.) Download (216 K).

CHAOS TO ORDER: The development of the Periodic Table of the Elements

Humans have always fought against chaos. The development of the Periodic table tracks the efforts to understand and organize the chaos. The table of elements started with just one element (water), then four elements, up to the present table that has well over a 100 elements.
Download (4 Megs)

WHERE DID THE ELEMENTS COME FROM?

The Periodic Table of the Elements lists the elements, but were they always here?  If not, where were they created? This journey starts with the elements beneath our feet and travels to distant galaxies. But it ends 15 billion years early at a point where you can easily touch.

THE MAGIC OF METRICS

This PowerPoint first points out the complexity of the English measurement system, which is why the metric system was invented. How metrics was invented is covered plus how it simplifies all of our measurements. Download (6.3 Megs).

CHEMICAL REACTIONS: Chemistry's Target

This presentation looks at the types of chemical reactions: Synthesis, Decomposition, Single Replacement, Double Replacement, & Combustion (oxidation). To demonstrate balancing, it uses the manufacture of bicycles, tricycles, and wagons as an analogy of how atoms are accounted for when balancing chemical equations.

SPECIFIC HEAT

A gram of water requires one calorie of energy to raise one degree. Other materials have their own specific amount of heat to be raised one degree. This property is called Specific Heat. This presentation also covers how this knowledge is useful.

THE GOOD NEWS & BAD NEWS OF CHEMISTRY:
This short presentation presents the good news about chemistry, which is atoms combine in simple ratios and most chemical reactions involve a small number (small count) of elements and compounds. However, the bad news is that they are two small to count and it takes so many of them to be of use.

SOLUBILITY, CONCENTRATION, & MOLARITY
This PowerPoint clears up some myths about water. It also teaches about the different ways of expressing concentration such as weight to weight percent, weight to volume percent, parts per million, and molarity. A few molarity problems are covered.

IDEAL GAS LAW: This presentation covers the history of gases and how they were put to work. It also covers how the PV=nRT formula came about. P=pressure, V=volume, n=moles, R=conversion constant, T=temperature. Counting molecules of gases is impossible, but they can be counted using the PV=nRT formula.
