CKSci Grade 2 Unit 3: Exploring Land and Water
Students explore the phenomena of different landforms, gathering evidence of how Earth events change Earth’s surface. Students also learn about weather patterns and the effects of wind and water on land.
Students explore concepts that include the following:
- Hills, mountains, valleys, rock arches, plains, geysers, volcanoes, sand dunes, and beaches are types of landforms.
- Landforms can be created quickly or slowly.
- Quick changes to landforms include rockslides, landslides, mudslides, floods, earthquakes, and volcanic eruptions.
- Wind and water can erode rock, sand dunes, and beaches.
- There are different solutions to prevent water from changing the shape of rock and to prevent sand erosion.
- Glaciers are frozen forms of water.
- Flowing water moves earth materials.
- Maps are used to help locate things in nature.
- The land and water features of an area can be modeled.
- Water soaks into the ground.
- Geysers and volcanoes bring underground materials to Earth’s surface.
- Sand landforms include dunes and beaches.
- Sand dunes and beaches are formed in different ways.
Scientists, including geologists and geographers, observe, analyze, and study Earth processes and changing landforms to describe patterns in the natural world to answer scientific questions. This series of lessons incorporates learning goals that support scientific principles and practices, such as analyzing and interpreting. Engineering practices are stressed in this lesson, with students considering ways of preserving rock formations, protecting beaches, and preventing landslides.
Number of Lessons: 6
Instruction Time: Each lesson is divided into 2-6 lesson segments. We recommend that you plan for about 30-45 minutes for each lesson segment.
