Spatial Concept Perspectives

We have gathered ~300 excerpts from published works about fundamental spatial concept terms. These have been cross-referenced with the concept lexicon appearing on the left. Those terms were drawn from the U.S.National Science Education Standards (NSES 1996) for topic areas B - Physical Science, C - Life Science, D - Earth and Space Science, as well as from the 1994 U.S. Geography Teaching Standards for grades 9-12. Those standards can be browsed here.

disciplinary perspectives on "gravity"

gravity

[OED]: 5. The attractive force by which all bodies tend to move towards the centre of the earth; the degree of intensity with which a body in any given position is affected by this force, measured by the amount of acceleration produced. Also often in wider sense, the degree of intensity with which one body is affected by the attraction of gravitation exercised by another body.
