It is important for humans to learn about Earth's systems and how we fit into this web of life. Take a journey with EarthCycle and expand your knowledge of geology, oceanography, and meteorology. This program illustrates how geologists study the subsurface.
Students use candy bars to simulate the stratigraphic exploration of a mountain.
Sampling error and extrapolation concepts are addressed. Finally, the candy bars are sliced longitudinally and compared with the cross sections. What-ifs is a part of Science Junction, an interactive science web site which has the goal of creating connections between the researchers and faculty at North Carolina State University and teachers, parents and students. What-ifs was created by Lisa L. Grable and April J. Cleveland for the purpose of encouraging inquiry investigations of water quality and collaboration between teachers and students. This site was designed to be a teaching and learning tool for teachers as well as students.
