NIHF-STEM Learners Discover Worm Population as an Invasive Species
On October 12th, our 7th-grade learners conducted some important field work in the Cuyahoga Valley National Park as part of their Problem-Based Learning unit on invasive species. This standards-based lab focused on invasive earthworms. The CVNP has an ongoing problem of earthworms over-decomposing in many parts of the park. Our learners worked with park rangers to draw the worms to the surface by pouring a solution of water and ground mustard onto a 30 cm square and then counting the worms. This helps the Rangers determine which areas are still being affected by an overpopulation of earthworms. When there are too many earthworms in an area it is difficult for new growth to take hold and regenerate forests. The Rangers were very thankful for our help and they will use our data to help them move forward with their reforestation plans.
