We will build a model tetrahedron to illustrate molecular geometry, first using it as a Silicon tetrahedron (SiO4), which comprises 90% of the Earth's crust. We will then use the same model as a Methane tetrahedron (CH4), the simplest organic molecule. This technique of modeling tetrahedrons was introcuced by the AIMS Foundation in 1985.
Our next model, a magnetometer, was introduced by TOPS Learning System and later developed for Windows to the Universe in 1995 to illustrate the detection of magnetism in such varied uses as space science, oceanography, geology, environmental science, archeology, engineering, and other critical applications for STEM Education.
Together these models will ignite curiosity and build confidence in science learners as they begin to see and manipulate abstractions.
