On May 5th, Mrs. McLoughlin’s fifth graders from Field School took a tour of the Case Campus. Among our stops was the vernal pool. On this day, we observed one adult frog in the water. It jumped underneath a log quickly so we were not able to note what type of frog it was. We also observed some type of film all over the water. Any ideas on what might have happened to the water surface? In a trap that Ms. Erickson left out, there were two predaceous diving beetles. One was very large, probably about two inches in length. And underneath a log nearby the pool, we spotted a sowbug. Lots of changes keep occurring over a very short period of time!
