A 4 DVD set containing approximately 44 segments showing various science demonstrations or illustrations of abstract concepts that a classroom teacher may not be able to do because of financial, time, safety or equipment concerns. Most demonstrations are followed by animations to illustrate and explain the abstract concepts.

Making Aspirin

Includes 3 15-minute programs. Part 1: "Alcohol, Tobacco, and Marijuana," Using animation as well as dramatic vignettes, this program focuses on the damage these these substances cause damage to the body and the brain.

Algebra helps our engaging teenage hostess, as she calculates the amounts of recipe ingredients needed to cook for and then serve, a sizable party:
1. To avoid confusion, when we write a formula we leave out the multiplication sign “x”, and instead put the number, the constant, in front of the variable, which is “X” in this case.

Continuing on from Part 1, more formulas are induced from patterns, this time concerning the number of trays needed to serve varying slices of pastries, that are more complicated than those in the first part. We combine formulas by adding and subtracting like terms. We call this simplifying the expression.

--formulas for a parallelogram (square, rectangle, and rhombus)
--formulas for a trapezoid, triangle, and circle
