We returned to our spot from yesterday to discover that the water from the vernal pond had evaporated significantly! We experimented with the water by throwing things and rolling natural items into it to see which would float and sink. We even worked together to roll a big log into the water! Some of us continued to build insect hospitals, while others dug for burdock root and yet others looked at plant books, attempting to identify plants. One Spark student enthusiastically dug by the vernal pond, exclaiming “I’m digging Mexican chinampas!”
