But occasionally, autumn rains collect in the same area. As we prepare for our first field visit we make entries in nature journals and sketch the things we observe. A journal is our main tool for recording our year long experience. On the field trip, students sketch plants they see growing in and around the pool and record observations. The area is also mapped and sketched into the journal.
Students pace the perimeter of the pool and measure the width using a surveyor's ruler.
The physical information they gather enables them to create a detailed map. Predictions of where frogs might lay eggs and questions such as what salamanders eat are also noted. The winter provides an opportunity to find out what mammals share the vernal pool as part of their home. Tracking skills are taught and sharpened in the classroom. Focusing on the patterns of footprints, students become familiar with the stories written in the snow.
