Grade 2. In 10 lessons over 13 class sessions, students explore the patterns of land and water on Earth and how they can represent those patterns with models, including maps. Module includes a teacher guide, 16 Smithsonian Science Stories student readers, teacher and student access to digital resources on CarolinaScienceOnline.com, and enough materials for 32 students to use 1 time.

Grade 2. Module Highlights: In 10 lessons over 13 class sessions, students explore the patterns of land and water on Earth and how they can represent those patterns with models, including maps. Exploring the kinds of land and water on Earth, students use their observations to create definitions of each kind of land and water, then demonstrate their understanding by developing a three-dimensional model. Students plan and carry out an investigation into the properties of solid and liquid water to explore the patterns of water on Earth, providing the knowledge to explain the patterns of solid water on Earth that they observe in satellite images. Students continue to obtain and use information from examples of patterns of land and water to further develop their three-dimensional models. Students read about maps from different cultures, exploring how mapmakers use symbols to show patterns of land and water, then create a custom legend using their own symbols. During the science challenge performance assessment, students make a two-dimensional map of their three-dimensional models of land and water. Students test their ability to interpret how the maps represent patterns by trading maps and matching the map to the correct model of land and water.

This module includes a teacher guide, 16 Smithsonian Science Stories student readers, and enough materials for 32 students to use 1 time.

Alignment to the Next Generation Science Standards*
Performance Expectations

• 2-ESS2-2: Develop a model to represent the shapes and kinds of land and bodies of water in an area.
• 2-ESS2-3: Obtain information to identify where water is found on Earth and that it can be solid or liquid.
• 2-PS1-1: Plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.

Disciplinary Core Ideas
ESS2.B: Plate Tectonics and Large-Scale System Interactions

• Maps show where things are located. One can map the shapes and kinds of land and water in any area.

ESS2.C: The Roles of Water in Earth’s Surface Processes

• Water is found in the ocean, rivers, lakes, and ponds. Water exists as solid ice and in liquid form.

PS1.A: Structure and Properties of Matter

• Different kinds of matter exist and many of them can be either solid or liquid, depending on temperature. Matter can be described and classified by its observable properties.
