Fertilizer Experiments in the Upper School


AP Environmental Science students engaged in an experimental design activity in the Academic Courtyard.  Each group of 3-4 students was allotted a small garden plot and asked to design an experiment to test a hypothesis that related to growth of fall crops such as lettuce, kale, and spinach.  Variables tested in different groups included type of soil (sandy, clayey, or good compost); relative density of seed planting; presence or absence of fertilizer; and presence or absence of mulch on soil.  None of the results were conclusive, but that is OK as the instructors learned a fair bit about how to guide students in experimental design next time around.  During the fall months, students were enthusiastically watering plants in their free periods, and all enjoyed the planting, harvesting, and data collection activities.  In addition, the proximity of the work space to the classroom allowed daily inspection of progress from the classroom windows.

What We Are Watching


From farmer to biodiversity expert, Cary Fowler, helps to manage the Svalbard Global Seed Vault in the Arctic Circle. Some call this site The Doomsday Vault, due to the fact that it is "nothing less than a backup of the world's biological diversity in a horticultural world fast becoming homogenous in the wake of a flood of genetically identical GMOs." In this TED talk he shares with us critical information about how biodiversity can save agriculture in a warming world.

Lower School Explorers Club



In the fall 14 students from GA's 4th and 5th grade Explorers Club, traveled to the Wissahickon gorge to study geology and climb on the rocks.  At the Andorra Nature Center, also in the gorge, children saw the oldest European Beech tree and climbed on it.  They had a full day,  looking for salamanders under rotten logs, hiking along the Green Ribbon trail, from GA to the Militia Hill State Park, and swinging on vines along the Wissahickon.  The Explorers club has also traveled  to Ruston Woods in Newton Square to learn about Saw-whet Owl research and the Briar Bush Nature Center in Abington.  Craig Newberger, faculty sponsor of the club notes that students will have more opportunities for exploring local natural resources in the spring term.
