A closer look at web tools and sites that boost research and empower Great Lakes communities to secure a healthy environment and economy.
Hundreds of invasive species are on the loose in U.S. waters wreaking havoc on habitats, recreation, and economies. Fortunately, a team of student detectives are on the case and ready to book these “bad guys” with help from Nab the Aquatic Invader!
This educational website turns students grades 4-10 into PIs hot on the trail of some of the worst invaders in their region. After brushing up on detailed profiles complete with interrogation recordings, students take part in ongoing investigations led by veteran gumshoes. Whether they join as junior detectives or super sleuths, students learn to ID the suspects, expose the damage they cause, and stop invaders before they strike again.
The site also includes a teacher Top Desk Administrator with example projects that give students a chance to share what they’ve learned with their communities. Along with detailed summary reports, these examples make it easy for teachers to plan and implement successful AIS stewardship projects in their own classroom.
But you don’t have to go online to crack a case. A suite of card games and posters inspired by the website are also available. Students and adults alike can even join the hunt for the most wanted AIS at the Smithsonian National Museum of Natural History in D.C. and at Coastal Ecosystem Learning Centers throughout the country.
Nab the Aquatic Invader! was created by IISG and Sea Grant programs in New York, Louisiana, Connecticut, and Oregon.

Since January, we’ve been busy helping students and educators dive deeper into hands‑on science! This winter, our team supported community engagement at the Step N2 STEM event, the Annual HASTI Conference, at Decatur Classical School, and at the Chicago River Student Congress.
Educators and students joined us to:
🔍 Explored macroinvertebrates up close
🌊 Learned about watersheds through an interactive game
🔬 Investigated plankton under a microscope
🦠 Engineered and raced plankton in the Great Plankton Race

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.
Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.
Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.
