Owl Pellet Dissection




Environmental Science students dissected owl pellets in their study of food chains, food webs, and trophic levels. They determined the owl's diet from the bones in their pellet. They also identified and sorted the bones from their pellets.

Field Trip to Clagett Farm






The Environmental Science class went on a field trip to Clagett Farm on November 6, 2008. Clagett Farm is Chesapeake Bay Foundation's sustainable farm. Students did sedimentation studies, planted cover crops, learned about rotation grazing and community supported agriculture, played environmental games, fed the cows, went on a hayride, and played a scavenger hunt in the woods. One of the favorites of the students was a tree with a large hole in the trunk named Sally Sycamore. They took turns trying to fit as many people in the hole. The trip was partially funded by the Chesapeake Bay Trust.
