NO PREP SUB PLANS: World Biomes – Freshwater STEM Design Series

NO PREP SUB PLANS: World Biomes – Freshwater Research + Group Project | Create a Comparative Poster | Grades 4–8
“Less than 3% of Earth’s water is fresh — and all life depends on it.”
Bring one of the most important (and often overlooked) biomes into your classroom! This No Prep Sub Plan introduces students to freshwater ecosystems—including rivers, lakes, streams, and ponds—through an engaging research and design task.
Students explore how freshwater supports life, compare flowing vs. still water systems, and create a comparative biome poster.

What’s Included
