This document contains daily assignments and questions from an Earth Science class. It includes questions about density, scientific methods, the formation of the solar system, and contributions of important scientists like Newton and Kepler. Students are provided information on upcoming tests and make-up policies. They are also reminded to turn in assignments and check the make-up work crate if absent.

- #2: http://www.elmhurst.edu/~chm/vchembook/122Adensityice.html What is the exact change in volume of the water when it freezes as ice? Comparison of: Liquid water Ice Mass = 100 g Mass = 100 g Volume = 100 mL Volume = ? mL Density = 1.0 g/mL Density = 0.92 g/mLExample: Calculate the volume in a 100 g ice cube with a density of 0.92 g per mL.Solution: The density translated as a conversion factor is: 0.92 g = 1 mL - "per" is equivalent to an equal sign. 100 g x 1.0 mL = 108.7 mL 0.92 g The increase in volume of ice is about 9%. This increase causes enough force to break most rigid containers. This is the same force, repeated on a daily basis, that creates "pot holes" in the roads in the winter time.
