Lab Safety/scienthic method
Scienthithic Method-procedure that has characterized natural science since the 7th century, consisting in systematic observation, measurement, and experiment, and the formulation testing and modification of hypothesis.

Earth Spheres
atmosphere-the envelope of gases surrounding the earth and other planets
biosphere-the regions of the surface atmosphere and hydrosphere of the earth occupied by living things
early earth- earths first billion years all hadean eon as well as the eoarchean and part of the paleoarchean eras of the archean eon
hydrosphere-all the waters on the earths surface such as lakes seas oceans rivers and sometimes including water over the earths surface such as clouds
lithosphere-the rigid outer part of the earth consisting of the crust and upper mantle.

Science lab disaster
two high school students got burned on accident when a science lab teacher truied to do an experiment on how to make fire different colors and menthanol made the fire spread.
