Counting Turtles Mark and Recapture Lab

Counting Turtles Mark and Recapture Lab
Product Description
Students use a cardboard box to represent their "pond" and several cutout paper turtles to represent their population.

Students take turns reaching in and capturing some of the turtles, and marking them with a highlighter.

Turtles are replaced and students take turns again capturing turtles. Using the provided formula, students are able to estimate the total population based on the number of recaptured turtles after round 2.

Lastly, students count the actual number of turtles in the pond to determine the effectiveness of the formula.
