As we continue our history of the Periodic Table organizational system and discovery of the elements, this program examines the elements lithium and beryllium. The characteristics of alkali metals and alkali earth metals are discussed in detail, with the help of graphics and animation demonstrating their similarities and differences. Students will learn why elements are organized into specific groups and their relations to the rows and columns of the periodic table.
The Periodic Table is organized with elements specified in rows, or periods, according to increasing atomic number. Metals are on the left of the periodic table, while nonmetals are located on the right. Some in the middle are called metalloids because they have characteristics of both metals and nonmetals. The periodic table is purposely arranged into vertical classifications called groups. Columns of elements help define element groups. Some of the notable groups of elements include the noble gases (column 18), the halogens (column 17), the alkali metals (column 1) and the alkaline earth metals (column 2). The transition metals are located in the center of the periodic table. They include many of the common metals, such as copper, iron, silver and gold. The two rows below the main body of the table are called the lanthanide and actinide series. They include the very heavy metallic elements, such as uranium and plutonium. This program goes in depth regarding the elements potassium (K) and magnesium (Mg) and their roles in the health of the human body. Potassium helps to control the proper balance of fluids in cells, helps with the contraction of muscles, and is involved in the transmission of chemical messages between nerve cells. Potassium aids in digestion of food, and in the proper function of the eyes. Magnesium is needed for more than 300 biochemical reactions in the body. It helps maintain normal muscle and nerve function, keeps heart rhythm steady, supports a healthy immune system, and keeps bones strong.
Chemistry has an impact on every aspect of our daily lives. The most important chemistry reference is the Periodic Table of the Elements. By providing a logical, mathematical method of organization, the table has become a critical tool for students, teachers and scientists around the globe. This program explores the discoveries that led up to the organization of the periodic table and how it is presently organized. It introduces and explores several elements (Hydrogen and Titanium) and their effect on our daily lives and the environments in which they occur.
It's not just for fashion; models are used to show even how the tiniest pieces of matters are outfitted! This program will outfit you with all you need to know about atomic mass, and will introduce the road map of elements known as the Periodic Table.
Topics include: Intro to the Atom, Atomic Mass, Atomic Number, Isotopes, The Periodic Table of the Elements, and Electron Energy Levels.
The Standard Deviants are so stoked to present this branch of chemistry, it has a leading role. Stoichiometry will awe you with mathematical performances and move you with a balancing act of equations. You will be applauding Stiochiometry's overwhelming performance.
Topics include: What is Stoichiometry?, the Metric System, Balancing Equations, Molar Conversions, Mass Percent and Empirical Formulas, and Limiting Reactants.
This program covers the very important topic of hydrate compounds. We begin by discussing what a hydrate compound is and why they exist in nature. We discuss how to name hydrate compounds using numerous examples. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned in this section are committed to long term memory.

This program covers the very important topic of ionic compounds. We discuss how ionic compounds form and how to predict ahead of time what the chemical formula will be when given the atoms that form the ionic compound. We spend a great deal of time discussing how to name ionic compounds. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned in this section are committed to long term memory.

This program covers the very important topic of naming molecular compounds. We begin by discussing how molecular compounds form and how they arise in nature. We discuss in detail the naming method for molecular compounds including all of the prefixes necessary to name any molecular compound. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned in this section are committed to long term memory.

Writing and balancing equations
1. Coefficients and subscripts
2. Word equations
3. Skeletal (unbalanced) equations
4. Conservation law of mass (no atoms lost or created)
5. Law of mass action, equilibrium, kinetics, rate laws (intro), Le Chatelier's principle
The program discussing the relationship of state functions and the physical conditions of a gas as well as early observations formulated as gas laws. Topics covered are:
Interrelationship of two state functions with one remaining constant (unchanged)
1. P,V (T=constant) Boyle's Law
2. V,T (P=constant) Charles' Law
3. P,T (V=constant) Gay-Lussac's Law
The s find out why molecules choose one carbocation over the other. Do they take the path of least resistance, or the road less traveled? After that, the s cover hydration reactions. Hydration reactions produce a neutral alcohol. How do they do it?
Find out about the most common variations of butane, like isobutane, butyl, and sec-butyl. Then the s look at the fabulous foursome: the four different types of carbons! We'll also learn more about complex alkanes.
Get keen on alkenes. The s continue their step-by-step process of how to name an alkene. Then, they're off to examine the molecular structure of this gang of rowdy molecules.
Give your students an overview of chemistry-yesterday, today and tomorrow. This live-action program includes a segment on the potential of buckyballs, the soccer-ball-shaped molecules that promises a whole new world of chemistry in the 21st century.
Part 1 is a short history of chemistry from the alchemists to the 20th century wizards. Part 2 includes exclusive interviews with outstanding modern chemists including Bassam Shakashiri, Regina Murphy, Spencer Silver (who invented the Post-It Note adhesive for 3M), Donald Huffman (who first made buckyballs), and others.
Describes how protein is intimately involved in life processes, and how proteins function as hormones; looks at the discovery of amino acids, their family formula, and polymerization of them; takes a look at peptides, denaturing albumin, and the levels of protein structure; and shows the lock and key model of enzyme action with an introduction to enzymes themselves.
