See the Applications for Science and Teaching pages for examples of how to use the Em2 for earth science, environmental scicence, geology, and more. Our model users include universities, K-12 schools, museums, and enviromental educators.


I had the privilege of attending Winona State University where we had multiple stream tables and a large flume. These tools provided me a major advantage as a geoscience student, but they also played a key role in our department's community education and outreach efforts. The tables naturally attract visitors of all ages! Children and parents alike let their curiosity guide them in conducting informal experiments - without even realizing it.

I also have to say, the staff working the tables at the Minneapolis GSA years ago were phenomenal folks. They so kindly gave me a mug (that I still use everyday!) for helping scoop sediment while they were busy with other visitors. We had a great conversation and it has always stuck with me what a difference it makes when you talk to people who clearly love their job. These people are passionate about their work. So if you have questions, I encourage you to reach out to them! It's worth it!
