We’ll bring our science programs to you.
We partner with school districts to support science learning. We offer district-wide elementary, middle, and high school programs, either virtually or in-person.
We collaborate with a range of partners to innovate in science education. Together, we go further.
Dive to the bottom of a lake.
1. Counting with quadrats: How do scientists measure how many organisms live in a habitat?
2. Clear water, murky water: How do we measure how clear or murky water is?
3. Dip dip, hooray: What’s living in your neighborhood body of water?
4. The scoop on habitat: What kinds of habitat do aquatic organisms live in?
5. Window under water: How can you see under water without getting wet?
6. Runaway runoff: How does the ground affect where pollution goes?
7. Water underground: Besides lakes and rivers, where can we find freshwater nearby?
8. Make a lake: Where do rainwater and snow go once they hit the ground?
9. The World’s Water: What fraction of the world’s water is found in lakes?
10. Water bugs: How do pollutants affect aquatic bugs?
11. Freezing lakes: In the winter, why don’t lakes freeze into a solid block of ice?

DIY Lake Science allows families and educators to investigate and learn about lakes and other freshwater ecosystems at home, at school, or anywhere you go! The app includes a dozen easy to use, hands-on activities to learn about freshwater ecosystems. Each activity includes step-by-step instructions that have been tested by educators, kids, and families. The activity materials are widely available and inexpensive—you probably have many of them in your home. Want to explore what happens under a lake’s surface? In the Under the Lake simulation, you can explore a process called lake mixing and how lakes change across the seasons, in different climates, and for different lake sizes.
