Estimating Population Size and Growth . Students estimate the sizes of theoretical populations using quadrat sampling and mark and recapture techniques, calculating experimental errors. They plot data showing logistic growth in a population of amoebas. Using a computer program they test hypotheses regarding population growth. Standard Assays of Water Quality .
