Exploring The Land in 5th Grade Science
In fifth grade science, the fifth grad theme, the land, features prominently in a yearlong study of geology, agriculture, and environmentalism. At the beginning of the school year, students take a close look at the land they see and interact with on a daily basis - the GUS campus - and consider some big questions that they continue to explore throughout the year: What land is important to us and why? How has the land changed over time, and how do we know?
With these questions in mind we explore the diverse landscape and geological history of the North Shore through a variety of projects and trips over the course of the year:
Square Foot Project
At the beginning of the year, each fifth grade student picks a spot along the GUS Nature Trail to claim as their own. A single square foot, individually measured and marked with twine, that they will observe at different times throughout the year. Students are asked to sketch what they see around them, use their senses to write a descriptive journal entry, and reflect on changes throughout the year.
Geology: North Shore + Beyond
Our study of geology began this fall in the GUS Greenhouse, where students made models of various landforms. We considered how they might have looked in the past, and what processes might have changed them to make them look as they do today. From there, we began to explore the evidence buried in rock layers and to understand how they can provide a window into the past, learning that the deepest layers of the earth often contain information about the oldest life on earth. We then created a timeline of the Earth’s history - and even did a mock fossil dig! We also studied the materials that make up the rocks themselves: minerals, and are now looking closely at crystals, the form that minerals take. This week we even ventured into the Harvard Museum of Natural History to see some for ourselves! In the coming weeks, we will head back out to the GUS Nature Trail to observe and consider what the land may have looked like in the past.
Soil at Appleton Farms
We paired up with Appleton Farms to explore soil and sustainability and to observe real-world applications. Through collaborative efforts with the farm's team, we learned much about how soil health and sustainable farming practices go hand in hand. Exploring the farm's diverse ecosystem, including pastures and tended fields, deepened students' understanding of soil, plants, and the environment. Discovering regenerative farming techniques and the significance of organic matter enrichment has underscored for them the critical role of sustainable practices in maintaining soil fertility and mitigating environmental degradation. This immersive partnership with Appleton Farms has broadened their knowledge and cultivated a profound appreciation for the interconnectedness of agriculture and sustainability.
Decomposition Study
Engaging in a decomposition activity, fifth graders eagerly observed items of various materials as they embarked on a seven-week journey of discovery. Armed with curiosity and scientific inquiry, they meticulously documented the transformation of a leaf, a slice of bread, an apple core, a plastic cap, aluminum foil, and paper, over time. Each material revealed its unique journey through decomposition, from biodegradable organic matter to non-biodegradable plastics. Through hands-on experimentation and close observation, students witnessed the gradual breakdown of these items and gained a deeper understanding of the environmental impact of different materials. This immersive experience fostered critical thinking skills and instilled a sense of environmental stewardship, empowering the next generation to make informed choices for a more sustainable future.
Camp Chewonkee Overnight Trip
This spring, fifth graders will head to Camp Chewonkee in Wiscasset, Maine, for a three-day overnight trip. This annual fifth grade rite of passage places students in a natural setting where they must work as a team to satisfy their basic needs (food/shelter) while remaining conscientious about their impact on the land. Students stay in campsites, process wood, and cook meals over a campfire. It’s an opportunity for students to challenge themselves and build their relationships with the land (and each other) - aptly extending their hands-on exploration of the world around them.
