Ocean Biome: Tide Pool Ecosystem

Use this Tide Pool Mini Unit to support your ocean biome or life science studies. This mini unit introduces young children to the tide pool ecosystem through simple language, realistic images, and hands-on materials.

This resource is designed for early childhood through early elementary science, with language and structure that support both Montessori classrooms and traditional life science instruction. Students will explore organisms, build food chains, sort organisms by diet and trophic level, and visualize the flow of energy through the ecosystem.

🌱🌏 Part of The Trillium Biomes Curriculum 🌎 🌱
The Trillium Biomes Curriculum supports background knowledge and vocabulary development through content-rich, coherent science and geography instruction. Children build conceptual understanding of ecosystems by exploring how living and nonliving elements interact within natural systems. Designed for developmentally appropriate, inquiry-based learning, the materials integrate science, geography, and language development while helping children develop a sense of place and connection to the natural world.
