The best way to understand a biome is to build (a model) one! A biome is a large zone on Earth characterized by its climate, soil, vegetation, and organisms with special adaptations for the unique environment. In modeling biomes, students will learn how they are different than similar ecological concepts like habitats and ecosystems. Students will discover how human activities, such as deforestation and habitat destruction, are transforming biomes. In this science-themed diorama class, students will be exposed to concepts such as trophic levels, the water cycle, biological competition, geographic isolation, convergent evolution, species diversification, natural vs unnatural climate change, food webs, habitat loss, and ecological niches, while they are working on their models. Grassland biomes are found on every continent (except Antarctica) and are flat, open regions dominated by grass with scattered trees and shrubs, and a warm, dry climate. Tropical grasslands, known as savannas, cover half the continent of Africa as well as areas of Australia, India, and South America. Compass ecologists will focus on African savannas where large, diverse animals such as elephants, wildebeest, warthogs, zebras, rhinos, gazelles, hyenas, cheetahs, lions, leopards, ostrich, and other birds and small mammals, graze and hunt in the expansive grasslands. Each student will create an individual diorama. Students will craft and hand-shape their scene on a 10 x 14 inch foam board using artistic, model-making techniques. They will customize their dioramas with landforms, waterways, plant life, and paint. Once individual projects are constructed, students will populate them with miniature figures and combine their dioramas alongside those of their classmates to create a larger terrain. Students will then compete in a zoology-based survival strategy game. Each student will create one board and receive a set of miniatures to take home with them. Course documents such as maps, game rules and all other instructional media will be available via a Google Drive link which will be emailed to parents. There is a $25.00 materials fee payable to the instructor on the first day of class. Topics in this series include: Tropics (The Rainforest)- Quarter 1; Tundra (The Arctic)- Quarter 2; Arid (The Desert)- Quarter 3; and Grasslands (The Savanna)- Quarter 4.

Step outdoors and into nature’s living laboratory! This outdoor science class immerses students in real-world field study where the woods, streams, and wetlands become the classroom. Each week, explorers will practice the methods of natural scientists as they investigate ecology, geology, zoology (local wildlife), botany (plants), ornithology (birds), mycology (fungi), and entomology (insects), in our own suburban ecosystem.

Students will observe natural systems in action as they examine life cycles, the water cycle, and the local watershed; explore suburban wetlands; and uncover the balance between producers, consumers, and decomposers, as well as predator–prey relationships and food webs. Seasonal cycles will guide discoveries as young naturalists watch habitats transform and learn how plants and animals adapt throughout the year.

Each week, students will explore the southern section of Sugarland Stream Valley Park in Herndon with a senior naturalist and outdoor educator. This program offers a refreshing break from sit-down, indoor, and screen-based learning—encouraging movement, fresh air, curiosity, and hands-on discovery. Students will learn to stop, look, listen, smell, touch, turn things over, and peek beneath the surface to uncover nature’s hidden wonders. A portion of every session will focus on developing confidence and comfort in the outdoors. Emphasis will be placed on safe, respectful, and responsible exploration, environmental stewardship, and appreciating what we find in nature. Students will also enjoy nature-based games that reinforce teamwork and exploration skills.

Venture outdoors each week to explore the woods with a senior naturalist and mentor while learning valuable survival skills. Students will learn how to construct a temporary shelter, make cordage, craft a bow and arrow, identify edible plants, track animals, and purify water. The group will learn knife safety and skills like whittling a spoon and spatula; how to use maps and compass (orienteering), and basic first aid. Students will practice animal and plant identification and will catch and identify macro-invertebrates to determine stream health (outdoor temperatures permitting.) Emphasis will be on becoming comfortable with things you encounter outdoors, safe exploration of the woods, how to be a good steward of nature, and what to do if you ever became lost or injured in the woods. Skills will be reintroduced and adapted each each quarter because the available plants, animals, materials, and water sources change with each season. Students will have a blast, develop greater self-confidence, and build a strong connection to nature and to the real world! Explorations in the woods is for enrolled students only, and tag-along parents and siblings cannot be accommodated.
