We head to the Downtown Berkeley Farmers’ Market to interact with the community on the second Saturday of every month. Our displays are always different, kid-friendly, and great for people who live for science, people who are lost by science and people who wish they loved science.

Are you a scientist, interested in co-hosting a table with us? Contact us at ucbclear@gmail.com

Are you a science enthusiast interested in attending one of our events? Follow us on social media to see even more pics and get all the event details, or email us at ucbclear@gmail.com to join our newsletter!

Please note that all upcoming Farmers’ Market events are postponed due to the COVID-19 shelter-in-place order. We will update this page as soon as the order is lifted, and it is deemed safe to congregate. Stay healthy everyone!

Fall 2018


Left: Fossils of Glossopteris like the one on the left helped scientists establish the theory of Pangea. Nearly identical fossils were found on continents separated by thousands of miles, suggesting that at one point, those continents were all connected.
Right: Fossil of Neuropteris, an ancient seed fern from the carboniferous period about 300 million years ago!
