On behalf of the Arvin Corporation, Buster Keaton demonstrates the importance of using Maremont auto parts for potential repairs while running a petrol station.

This DVD dives into the advanced principles of Algebra. The Standard Deviants tour of the world of algebra continues with complete coverage of quadratic equations, quadratic roots and factors, and higher order polynomials. Suitable for all ages, Algebra Part 2 clearly presents these principles in a fun and approachable manner. A completely stand-alone video! Part 1 is not required.

This edition of Trigonometry includes such topics as radians, the special angles, right triangles, the Pythagorean Theorem, sine, cosine, tangent, law of cosines and law of sines.

Part 2 starts off with a quick review of graphing as well as sine, cosine and tangent. From there, this video charts new territory as we dive into amplitude, curves, double-angle formulas, sum-to-product-formulas and identities. Using computer graphics and animation, the Standard Deviants illustrate these complicated concepts far better than any blackboard!

A film about the Veluwe region of the Netherlands, by the director of the Gemeentelijke Schoolbioscoop in Rotterdam. We see detailed images of villages, towns, moors, streams, ponds, poultry, and sheep farming. Van der Wel shot his own footage (according to the intertitles), but also used existing films. He drew mainly on the ‘city films’ from the catalogue of HAP & BenS. We see, for example, images from the films "Oosterbeek aan den Rijn" and "De Steeg" made by the Arnhem film company AFKO; and from the films made for Haghe Film "From Arnhem en omstreken" to "Barneveld and Elburg", directed by Willy Mullens.

This film is a treasure. It's one of the best examples of the theory and practice of the art of camouflaging military targets from air observation & attack that you'll find anywhere, presented in a highly entertaining Disney style full color animation supplemented by live action film. Hosted by “Yehudi the Chameleon,” the action is centered around a P-39 Airacobra base in the Pacific and is chocked full of useful information & “how-tos.” Some of the many things you'll learn: how camouflage works in Nature, analyzing the specific camouflage needs of your location, theories and application of different camouflages, hiding in shadow, using camouflage netting, creating dummy targets, breaking up distinctive shadow lines that outline structures, concealment by “blending,” making “trees,” hiding routes & paths or creating fake ones, hiding targets in plain sight by adding minimal camouflage and more.

Ceschi and Stamm's documentary tells the incredible story of Monika Krause, a former East German citizen, who became Fidel Castro's Sexual Education Minister.

A film about potent female agitators, staunch macho men and Caribbean love lives.

Until recently geometry was 'cold', incapable of describing the irregular shape of a cloud, the slope of a mountain or the beauty of the human body. With fractal geometry, Benoit Mandelbrot gave us a language for our natural world. In this captivating documentary, the man himself explains this groundbreaking discovery.

Two eighth graders doing an assembly on cleanliness and neatness seek underclassmen. A look into Don and Mildred's hygienic endeavors.

This documentary looks at developments in the Canadian forestry industry from the 1970s.
