Dow Wetlands Fieldtrip, December 9, 2005

Goal: To compare the biodiversity of the wetlands to the Pittsburg High schoolyard.

The Field Trip: We took a day trip to Antioch, CA where Dow Chemical company has an extensive restored wetlands. Here we saw river otters, cattails and more than 20 species of birds (see bird list below)! We used the same methods of collecting insects and plants to compare the biodiversity of the wetlands to the Pittsburg High schoolyard. These images tell at least part of the story.

The class listens to Sheryl Sturges give an introduction about the park ecosystem. Ryan, Danica, and Joel ask Sheryl questions about the park.

Maribel, Cesia, Jasmin, Miriam, Veronica, Micaela, and Yareli look at birds that Sheryl has located with the viewing scope.

The Dow Wetlands as seen from a viewing platform. The students watch a great blue heron that is standing out in the water. There are many other birds in the area, though they are not visible in this picture.

Students write in their field notebooks at the viewing platform. From this platform, students can see a large area of the wetlands and use the spotting telescope to see birds.

Ryan Hill shows Brian, Yareli, Micaela, and Abel how to sample the water to see what animals are there. The class found fish, immature insects, and small shrimp.
