Grade 1 - Plants and Animals of Seas and Rivers
SUMMARY
A 6-8 Week Unit for Primary Level
This unit is designed for First Grade, but could be adapted to other primary grades. Students discover the wide variety of living things that are found in and near the water, through investigations and games in the classroom and active observation outdoors. They practice science skills of noticing details, comparing, sorting, measuring, questioning, recording, and communicating. Science notebooks are used throughout the unit to help students understand and organize information, and many activities are integrated with math, language arts, art, and social studies.
Essential Question
- What kinds of plants and animals live in or near the water?
Enduring Understandings
- Plants and animals can be sorted into groups based on different characteristics.
- People use the plants and animals of the seas and rivers in different ways.
Ocean Literacy Principles Addressed
- The ocean supports a great diversity of life and ecosystems.
- The ocean and humans are inextricably linked.
LESSON PLANS

ABC Sea/River Book
Students create an ABC Sea/River Book by illustrating and describing local aquatic plants or animals, emphasizing letter sounds and detailed observations, then share their work to enhance understanding and communication skills.

Marine/Freshwater Animal or Plant Riddle
Students create riddles based on marine or freshwater animals, using research to craft clues, and present their work in a display or celebration to engage others in guessing and learning about aquatic life.

Sharing What We Know
Children will reflect on what they have learned as they complete the O-W-L chart that they began in Investigation 1. They will plan ways to share their new knowledge with the whole school and/or community and prepare for an Alaska Seas and Watersheds Celebration. After learning and practicing ways to present information, they will display and present their work to others.
