Learning about ecology and environmental science in lower elementary (K-3) introduces young students to the relationships between living things and their surroundings, fostering early awareness of ecosystems, conservation, and sustainability. These concepts align with Next Generation Science Standards (NGSS) and state frameworks, emphasizing hands-on exploration and observation. Here is how it is structured by grade:
Kindergarten—Basic Needs of Living Things:
- Learn that plants and animals need air, water, food, and shelter to survive.
- Compare how different animals (e.g., squirrels vs. fish) meet their needs.
- Activity: Plant seeds and observe growth, or create a "habitat collage" for an animal.
First Grade—Interdependence in Nature:
- Explore how plants and animals depend on each other (e.g., bees and flowers).
- Identify how humans use natural resources (water, wood, soil).
- Activity: Build a simple food chain with pictures or act out animal roles.
Second Grade—Habitats and Biodiversity:
- Study diverse habitats (forests, oceans, deserts) and their unique organisms.
- Discuss how animals adapt to their environment (camouflage, hibernation).
- Activity: Design a mini-habitat in a shoebox or take a nature walk to document local species.
Third Grade—Environmental Changes and Human Impact:
- Investigate how natural events (fires, floods) and humans (pollution, recycling) affect ecosystems.
- Introduce conservation (e.g., reducing waste, protecting endangered species).
- Activity: Track classroom trash for a week and brainstorm solutions.
Key Standards:
- NGSS K-LS1-1: Needs of plants/animals.
- NGSS 2-LS4-1: Habitat diversity.
- NGSS 3-LS4-4: Human impacts on ecosystems.
Teaching Approaches:
- Nature-based play: Bug hunts, leaf sorting, or weather journals.
- Storybooks: The Lorax (conservation), Over and Under the Pond (ecosystems).
- Projects: Build bird feeders, start a compost bin, or create "recycle vs. landfill" sorting games.
By 3rd grade, students understand their role in protecting the planet—laying the groundwork for deeper ecology studies in later grades.
