Lesson 34: Logarithmic Scales
Description:This lesson introduces logarithmic scales as a means for plotting data that might otherwise be difficult plot due to their widely varying values. Instead of plotting the actual values, the values of their logs are plotted on a scale of powers of ten. A discussion follows that highlights an unfamiliar feature for students: equal intervals on the power of ten scale do not correspond to equal values. Various application problems about acidity and ph, decibels, and the Richter Scale follow.
