Student Exploration: Estimating Population Size Gizmo Answer Key Pdf
As a student, you might have come across the Estimating Population Size Gizmo Answer Key Pdf while studying biology. This Gizmo is an online simulation that allows you to estimate the size of a population by using a mark-and-recapture technique. In this article, we will go through the basics of the Estimating Population Size Gizmo and provide you with the answer key pdf.
What is the Estimating Population Size Gizmo?
The Estimating Population Size Gizmo is an online simulation developed by ExploreLearning that allows you to estimate the size of a population by using a mark-and-recapture technique. This technique is commonly used by biologists to estimate the size of a population that cannot be easily counted. The Gizmo provides a virtual environment in which you can practice this technique and understand how it works.
How does the Estimating Population Size Gizmo work?
The Estimating Population Size Gizmo works by simulating a population of animals in a virtual environment. The animals are represented by colored dots, and the population size can be adjusted using a slider. You can capture a sample of the animals by clicking on them and marking them with a colored dot. You can then release the marked animals back into the population and capture another sample.
The Gizmo uses the mark-and-recapture technique to estimate the size of the population. The assumption is that the proportion of marked animals in the second sample is proportional to the size of the population. This means that if you mark and capture 10% of the animals in the first sample, and then mark and capture 10% of the animals in the second sample, the proportion of marked animals in the second sample should be around 10%. Using this proportion, you can calculate the size of the population.
How to use the Estimating Population Size Gizmo?
To use the Estimating Population Size Gizmo, you need to follow these steps:
- Open the Estimating Population Size Gizmo on your web browser.
- Adjust the population size using the slider.
- Capture a sample of the animals by clicking on them and marking them with a colored dot.
- Release the marked animals back into the population and capture another sample.
- Record the number of marked animals in the second sample.
- Repeat the process several times to get a more accurate estimate.
