DIY Lake Science, developed by the University of California Berkeley's Lawrence Hall of Science, is an educational app that allows families and educators to investigate and learn about lakes and other freshwater ecosystems. This free app, funded by NSF, provides a variety of hands-on activities, simulations, and videos to engage users in learning about the fascinating world of freshwater ecosystems.

The app features a dozen easy-to-use hands-on activities that provide step-by-step instructions for learning about freshwater ecosystems. These activities have been tested by educators, kids, and families, and the materials required for the activities are widely available and inexpensive. Whether at home or in the classroom, users can easily access these activities and explore the wonders of freshwater ecosystems.

One of the highlights of DIY Lake Science is the "Under the Lake" simulation. This simulation allows users to explore the process of lake mixing and how lakes change across seasons, climates, and sizes. By diving into this simulation, users can gain a deeper understanding of the dynamics of freshwater ecosystems and the factors that influence their behavior.

In addition to the hands-on activities and simulations, DIY Lake Science also provides collections of videos showcasing lakes and other freshwater ecosystems from around the world. Users can learn about the diverse plant and animal life that inhabits these ecosystems, the scientists who study them, and how people can contribute to their conservation and care.

Overall, DIY Lake Science is a valuable educational resource that brings the wonders of freshwater ecosystems to life. Whether at home or in the classroom, users can engage in hands-on activities, simulations, and videos to deepen their understanding and appreciation for these important ecological systems.
