Nature of Science: Meters, Liters, and Grams!

Our entry task for the day was to watch The Inner Life of a Cell (below), a video created by the Harvard University group BioVisions.  The video perfectly complemented the reading students did yesterday, bringing to life the processes that occur inside and outside the cells in our bodies.  After the video, we discussed the scale of cells, with students learning that white blood cells are only 6-8 μm in diameter (one micrometer (μm) is equal to one-millionth of a meter).  We then created class lists of tools scientists use.  Each class added to a growing list, and tomorrow we will categorize our large list.  We concluded with a worksheet where students practiced making calculations using metric units.  The base units were introduced through the artistic talents of teacher Pete Hendley (actually, his alter ego KILA META) in his amazing rap video, “Meters, Liters, and Grams.”  Be warned – it will stay with you 😉

UPDATE: Students may skip worksheet questions 10-13.  My attempts to show the math steps actually made the work more confusing for most students.  Please work through problems 1-20 as homework, skipping 10-13.
