Studies of meteorites and comets suggest that organic molecules are widespread among both asteroids and comets. ecause each body in the solar system was repeatedly struck by asteroids and comets during the period known as the heavy bombardment (about 4 billion years ago), each body should have ...
Asomewhatstricter requirement is the presence of these elements in moleculesthatcan be used as ready-made building blocks for life, just as early Earth probably had an organic soup of amino acids and othercomplexmolecules building blocks of live 生命基石 The set of elements (or their relative pr...
Earth' s organic molecules likely came from some combination of three sources: chemical reactions in the atmosphere, chemical reactions near deep-sea vents in the oceans, and molecules carried to Earth by asteroids and comets. The first two sources can occur only on worlds with atmospheres or ...

The character in the chair is a pretty good Schrodinger! I have had student groups build banners on the history of chemistry, design HyperCard stacks (there is an old one for you) on the elements and their compounds, create videos on elements, create 3D models of molecules and ancient ...
Gray begins with an explanation of how atoms bond to form molecules and compounds, as well as the difference between organic and inorganic chemistry. He then goes on to explore the vast array of materials molecules can create, including: soaps and solvents; goops and oils; rocks and ores...
