Follow the steps to successfully complete the form

1. Press the ‘Get Form’ button to access the downloadable version of the Population Ecology Lab worksheet. It allows you to open and fill the form in your compatible document editor.
2. Begin by entering your name, class period, and date at the top of the form. These details personalize the form and help in organizing data.
3. In Column A, start with '0' to indicate that no goldfish have been marked yet. This sets a clear baseline for your population study.
4. Use a medicine measuring cup to collect a sample of goldfish from the population. Record the total number of goldfish you collected in Column B.
5. Using a marker pen, mark each goldfish from your sample. This is critical as it identifies the goldfish that have been captured initially.
6. Record the count of marked goldfish in Column D. By returning these marked goldfish to the population, you complete this round of data collection.
7. Update Column A again with the total number of marked goldfish present after your first capture. This ensures your population count remains accurate as you proceed.
8. Mix the remaining population and obtain another sample. Repeat the recording process: total number of goldfish in this sample should go into Column B, and the count of recaptured marked goldfish in Column C.
9. For any new goldfish captured, mark them as well and return all marked goldfish to the population, which helps in maintaining integrity in your sampling process.
10. Continue recording the total number of marked goldfish in Column A after each sampling round to track changes throughout the experiment.
11. For the last four samples, use the provided equation to estimate your total goldfish population size. Calculate this for clarity in your results.
12. Average the population estimates for the last four samples. This average figure will represent your estimated goldfish population size.
13. Finally, count the actual number of goldfish you have. Compare the estimated number with the actual count and calculate the percent error using the specified formula.
14. After all your entries, make sure to save changes to the document. You can also download, print, or share the filled-out form as per your requirement.
