Biology 6C 63 Exercise 3A [Pre-Lab] Estimating Population Size Adapted from Biology Corner Scientists cannot possibly count every organism in a population. One way to estimate the size of a population is to collect data by taking random samples. In this activity, you will look at how data obtained from random sampling compare with data obtained by an actual count. The grid shown below represents a meadow measuring 10 m on each side. Each grid segment is 1m x 1m. Each black circle represents one sunflower plant. Procedure: 1. On the last page of this pre-lab is a table with numbers and letters representing the grid segments in the “meadow” above. Cut the boxes apart, keeping numbers and letters separate. Place the numbers in a pile upside down on the table and the letters in another pile upside down on the table. 2. Randomly remove one slip from each pile. Write down the number-letter combination and find the grid segment that matches the combination. Count the number of sunflower plants in that grid
