Fundamentals of Geometry

Geometry Corn Maze Project Information - A real-life mathematics quest applying naturalistic learning to mathematics problem solving.

The Theorem of Pythagoras Java applet - A graphical representation of the famous theorem explaining how the Chinese discovered the same theorem much earlier than Pythagoras.

Stevenson Towers Volume Problem - Use the digital picture to estimate the volume of one of NIU's largest residence halls.

Volume of a Sphere Problem - Use the digital picture to estimate the volume of a sphere obtained by wrapping the sculpture to create a cylinder.

Satellite Orbit Java applet. - Put your very own satellite into orbit, without it crashing or escaping, while studying the effect of velocity vectors on orbital motion.

Electron Orbit Java applet. - Put an electron into orbit around a proton by generating a stable elliptical orbit using velocity vectors.

The Parallax Effect - A great application involving geometry, astronomy, circles and tangent angles.
