Population Sampling Lab

This is a simulation, not real field data. In each part you will estimate a hidden number, then check how close you were.

Part 1: Count the plants in a few squares of a meadow and estimate the whole meadow. Try picking the squares yourself, then try Random. Click a square to count it, or use arrow keys and Enter.

Part 2: Catch fish, tag them, and release them. Catch a second batch and use the tagged fish you find to estimate the whole pond.

Part 3: See what happens when tags fall off or tagged fish dodge the net. Make a prediction first.

Record your results and answer the questions on your worksheet. Nothing is saved or sent. Reloading or changing language clears your work.
