Rocket Car Race Chassis and Wheels – Thrust, mass, and acceleration can be explained by stepping through the basic rocket principles. Source: Thingiverse – EXO2, published Science This video demonstrates that even today Archimedes Trammel is useful in a real world situation! Here is a fun video from a young boy who built a trammel with his father from Legos, and he gives a simple explanation to its use.

In other words, it is a device used to draw a near perfect ellipse using mechanical means. Source: Thingiverse – WongZCMS, published Aug 11, 2013Ģ) Archimedes Trammel – is a mechanical device which produces the shape of an ellipse by using 2 shuttles which move in the x and y direction. Additionally, the How Stuff Works website published this How Bridges Work article discussing everything from the basics of bridge design to living bridges. Additionally, this link lists 8 videos discussing building bridges concepts. As a set, they demonstrate the characteristics of various bridge designs. Source: Thingiverse – SSW, published Engineeringġ) Modified Howe Bridge – Engineering Project (STEM) – WongZCMS designed this bridge as one of three designs to discuss and demonstrate bridge concepts with his class. You can also refer to this video that illustrates and explains gear speed, direction, circumference, diameter, and radius concepts. Home Science Tools has this short discussion explaining types of machines and various aspects of gears and their uses. Math Gears – This design is easily used with overhead projectors and demonstrates ratios and mechanical engineering. Source: Thingiverse – henryseg, published Math & Engineering

Also, included on the Thingiverse page linked below is a great video discussion of stereo projection! Source: Thingiverse – pdragy, published Mar 4, 2014Ĥ) Sterographic Projection – defined by stereographic projection is a “one-to-one correspondence between the points on a sphere and the extended complex plane where the north pole on the sphere corresponds to the point at infinity of the plane.” In other words, it’s a map from the sphere to the plane. This Polyhedra video is a discussion explaining what they are, how they are named, and how they are classified. The customizer alone makes this page worth a venture just to see the names and shapes together…it’s incredible! Make sure to visit the customizer and play around viewing the different shapes.

And what teacher has not used the proverbial slices of pie example to clear those glassy eyes? Well, these slices of pie can be used over and over again without getting pie filling all over the classroom! Let’s Learn Fractions is a short video that fully discusses fractional concepts.
