Scale of the Universe


Lesson objective: students can plot data of varying magnitudes on a semi-log scale.

This is a lab day, and students log on to find this website: http://htwins.net/scale2/lang.html

They then pick 12 objects of various sizes and write down their names and sizes in meters.  The interactive website displays data between the two extremes shown below, and naturally student choose some from each side of the spectrum, which makes it hard to graph using a base 10 scale


As students enter I hand them this worksheet that will guide them through the activity.  After they pick their 12 objects they plot them on semi-log scale graph paper.
