How do barnacles like their lemonade?

By: Peter, Aaron, Rosie–

On the rocks!

Today we got to do actual scientific research with the help of Will King, a grad student at University of Washington. We conducted an observational study of how barnacle size correlates to its position in the intertidal zone. We learned that the optimal position for barnacles is to be high enough away from predators but also close enough to the water to obtain food. We observed that the larger barnacles were located at a middle point and they got smaller as elevation increased and decreased.

After lunch, we had the pleasure of rummaging through old treasures at the local thrift store to find pieces for the Invertebrate Ball coming up this weekend. Everyone was attempting to channel their inner invertebrate as people were looking through old sweaters, garden supplies, and sports gear. We are all excited to debut our final product on Saturday.

We got to top off the day with a lovely Mediterranean inspired dinner and an interesting talk about terrestrial (WHAT?) organisms with scientific duo Dr. Erika (Muhlenberg College) and Dr. Vik Iyegar (Villanova University), both ecologists doing summer work at the Friday Harbor labs. We learned some interesting facts about earwig sexual behavior as well as slug populations and interactions on San Juan Island.

From slimy slugs to brittle barnacles, the day was packed with learning about important small beings.
