Hayground School Scientist in Residence Sarah Sander and the students have been very busy over the past few weeks moving into their next round of research. The study of hermit crabs is continuing. This past week, students studied the speed by which a hermit crab travels. They tested the crab on a table, in sand, and in water. The hermit crab proved to be fastest in water, just beating out sand. The crab was slowest on the table, with the students hypothesizing that this was due to the lack of grip with the surface (friction).
Students have also been busy with their studies of germs. The students recently tested different produce—all loose and unwashed—including lettuce, apples, pears and lemons. Lettuce proved to have the most germ colonies. Students are now moving into testing various fast foods for germ colonies.
A few students recently attended a composting seminar held by Marder’s Nursery. This was an extremely informative day, and the students are now starting a composting project at the school. This will complement the Slow Food Greenhouse that students and families, along with Slow Food volunteers, are currently erecting at the school.
The school will be welcoming five Ph.D. candidates from Cornell University the first week of April. These science students will be working with the Scientist in Residence program on a variety of botany and bird studies. Additionally, this will be the official kickoff of the school’s new greenhouse and gardening programs.
