The student uses critical thinking and scientific problem solving to make informed decisions. Represent the natural world using models and identify their limitations. Students employ a model in their investigation of craters. The model meteorites are small rocks, marbles, or ball bearings. When dropped into a pan filled with grits, cornmeal, and cocoa, the model meteorites form craters with raised ridges and rays of debris.
Some students notice the model limitations.
High speed model meteorites bounce off the bottom of the pan, which may affect the size of the crater. The student knows how to use a variety of tools and methods to conduct science inquiry. Students use metric rulers to measure the size of the craters. Students perform three trials of each experimental meteorite drop into the pan. 6.6 Science concepts .
