Individual Video Tapes on Chemistry
The following 6 tapes are currently available:
- Atomic Structure: Mapping an invisible World.
Journey through the history of the atom an see how models of these particles
of matter have changed over time. Dynamic animations and graphics bring to
life the different atomic models of Bohr, Rutherford, Dalton and others. Other
important concepts such as atomic mass, number, isotopes, subatomic particles
and radioactive particles are covered. Includes a teacher's guide with lesson
plans, student activities, discussion question and script. Length 22 minutes.
- Race to Catch a Buckyball. Learn
about the third known form of pure carbon.This fascinating video explores
the unexpected discovery of C-60, also known as buskyminsterfulrene or buckyballs.
Length 60 minutes.
- Compounds: Electromagnetic Attraction in Molecules.
This video with its animation and striking graphics helps to explainthe concept
of chemical bonding in compounds. Topics addressed include whether bonding
is ionic or covalent, the chemical equations and chemical formulas created
by the compound, and the conservation of matter. Other subjects include endothermic
and neutralization reactions. Contains examples of everyday materials which
are a product of chemical bonding. Includes a teacher's guide with lesson
plans, student activities, discussion question and script. Length 24 minutes.
The
Periodic Table: Reactions and Relationships. Familiarize your students
wit the building blocks of the universe. The program explains the periodic
law and the significance of the rows and columns of the periodic table. It
also outlines the physical and chemical qualities of the members of each group
of elements from the alkaline metals to the noble gases. Complete with a teacher's
guide with lesson plans, student activities, discussion questions and script.
Length 25 minutes- Reactions: The Chemistry of Change.
Take a look at the importance of chemical reactions in the lab and everyday
life. Several types of reactions are presented in this video, including exothermic,
endothermic, spontaneous and non-spontaneous. Additionally this video shows
how these reaction are affected by other variables such as temperature, concentration,
and the presence of a catalyst. The notions of chemical equilibrium and reversibility
are also addressed.Includes a teacher's guide with lesson plans, student activities,
discussion question and script. Length 27 minutes.
- Mixtures: Together but Separate. Introduce
students to the differences between mixtures and compounds. Types of mixtures
such as suspension and colloids are introduced, as well as how they can be
separated. A comprehensive look is taken at such concepts as: solvents, solutes,
electrolytes, saturated solutions and polarity. 3-D animations demonstrate
how solubility is affected by the polarity of a solvent or solute. Includes
a teacher's guide with lesson plans, student activities, discussion question
and script. Length 22 minutes.
