Third grade students have been learning all about tides during the science unit on the Earth, Moon and Sun. They have been studying the gravitational physics behind tides, as well as unique adaptations that organisms have evolved to survive in the intertidal zone. A field trip to Alki Beach during an ultra low tide was the perfect hands-on way to experience these phenomena in person!

While sloshing around in seaweed, the students teamed up to work on a scavenger hunt, looking for the plant and animal species they learned about in class. They also took on the role of field biologist, searching for other species not appearing on their field guide. They found an impressive number of marine animals – including nudibranchs, sea cucumbers, anemones, and eels!

The trip was an engaging, fun, capstone to the year and an exciting way to experience biology up close.
