STUDENT ACTIVITY - 5th Grade: This is a distance-learning lesson that students can complete at home. The student will explore the biome in which they live while comparing it to other major biomes around the world.This activity was created by Out Teach (out-teach.org), a nonprofit providing outdoor experiential learning to transform Science education for students in under-served communities.
