Exploring Our Fluid Earth

This activity was supposed to be in preparation for an intertidal field study, but we ran out of time in the school year, so we just did it in the classroom. My students (9th grade Marine Science) enjoyed it a lot. I had some bulletin board cutouts of sea stars, snails, and fish that I threw down on the floor amongst the popsicle sticks and index cards and the students liked them so much they asked if they could take them home :)
