In this performance task, you will answer six questions.

While on a nature trip to a grassland, students observe a black-tailed prairie dog colony.

Prairie dogs form large family groups that live together in the same underground burrow with many offspring. This picture shows an example of a prairie dog burrow.

Living in a group helps prairie dogs survive. When a predator is close by, prairie dogs bark loudly by making yipping sounds and warn the rest of the family to hide.

Prairie dog colonies create habitats that benefit other species, and they are a food source for many predators. A farmer decides to donate some of her land to become a nature preserve that will support prairie dog colonies. The farmer wants to keep at least 10 square kilometers (km2) of her 25 km2 of land to produce crops that support the local community.

Students use colored tiles to create these three different models of the farmer’s land. Red tiles represent land the farmer will donate, and white tiles represent land she will keep farming. Each tile represents 1 km2.
