DIY Lake Science, funded by NSF, allows families and educators to investigate and learn about lakes and other freshwater ecosystems at home, at school, or anywhere you go! Developed by UC Berkeley’s The Lawrence Hall of Science.

HANDS-ON ACTIVITIES
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.

UNDER THE LAKE
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.

VIDEOS
View collections of videos of lakes and other freshwater ecosystems around the world! Learn about the plants and animals that live in lakes and other bodies of water, the scientists who study freshwater ecosystems, and how people can care for lakes.
