You will find a discussion of the Standards and our correlations here . The Absorbency of Rock Learn about the ability of rock to absorb liquids. This Science Lab activity provides instructions and materials for building a paper model of a Fullerene, a truncated icosahedron. How do underground buildings remain relatively warm in the midst of the brittely cold winters on the Great Plains. The Energy Efficiency experiment offers some insight into why this is so.
Interesting patterns emerge when worldwide data is accumulated and compared.
In the 1920 s Edwin Hubble discovered that not only were all the galaxies in the universe were moving away from us, but that the farther the galaxy was from our own, the faster it was moving. Using a rubber band we can understand why Hubble's discovery makes sense. Although professional logging tools are complex precision instruments it is possible to build working models that funtion in basically the same way. The Electrical Resistivity of Materials Discover how rock can conduct electricity, and find out how scientists identify underground rock by its electrical resistivity. The nuclei of some atoms can be made to line up with a magnetic field.
