Introduction to scales and map interpretation

bulletInterpreting pictures and scale
bulletWorking with ratios
bulletBuilding a map of a known location
bulletCalculating areas and perimeters of invaded marsh (different shaped objects)
bulletCalculating rates of expansion from measured data

How fast is the invasion?

bulletUsing mapping and scale to solve real world problems
bulletUsing measurements of distance and time to calculate rates
bulletExtrapolating from an existing set of data to predict future trends.
bulletCalculating areas of regular shapes (rectangle, oval) in order to solve real world problems
bulletCalculating percent in the context of a real world problem
bulletUse of critical thinking skills to assess patterns observed within a data set

Quadrat sampling

bulletCollecting data on species diversity and abundance in a map of a series of model marshes
bulletWorking with averages (mean, mode, median), range and percentages
bulletCreating meaning for mathematical ideas like density and rates

Effective Graphing Part 1   and Part 2

bulletReviewing which graph to use in what context and why
bulletReviewing independent and dependent variables
bulletApplying this to determining which variable is X versus Y
bulletAssessing whether a variable is continuous or discrete
bulletGraphing data collected in previous day's classes (rates, diversity, abundance, relationships)
