Thursday
SRE This!

Imagine that you have four buckets full of dark, muddy water. One bucket is frozen, one bucket is boiled, one bucket is shaken up, and one bucket is passed through a paper filter. Which bucket is most likely to become lighter in color? (SC.5.P.8.3)
 * 1) A. The frozen bucket, because the mud separates from the water.
 * 2) B. The shaken bucket, because shaking causes the mud to dissolve.
 * 3) C. The boiled bucket, because the dirt in the muddy water evaporates.
 * 4) D. The filtered bucket, because larger particles of dirt were strained out.
