Kindergarten - Discovering Our Blue Planet
SUMMARY
A 3-4 Week Unit for Primary Level
This unit is designed for kindergarten, but could be adapted to other primary grades. Students discover aquatic environments and the living and nonliving things that are found in them, through active observation outdoors and in the classroom. They practice skills of recording, comparing, questioning, and communicating. Science notebooks are used throughout the unit to help students understand and organize information.
Essential Question
- What are the characteristics of the living and nonliving things you discover in the water?
Enduring Understandings
- Living and nonliving things in Alaska waters come in a great assortment of colors, shapes, and sizes.
- Living things move, grow, and change.
Ocean Literacy Principle Addressed
- The ocean supports a great diversity of life and ecosystems.
