There are really only two numbers in biology, one and two. And I am not so sure about two. The use of math in chemistry and physics is straight forward. In biology the numbers simply do not work out to 2 or 3 place accuracy most of the time. Experiments that work one day, may not the next, or at least will result in slightly different values.
Life is fuzzy, requiring a softer approach to numbers.
Math is, however, essential to the biologist and is used extensively. The lessons presented are a starting point for designing your own. We have attempted to present the material in a logical and orderly manner. More information and activities are presented than can be accomplished in one or two class periods. Only you know how much your students should attempt and what skills they will need.
