5th Graders begin their study of Earth Science!

Dear parents and families,

Human beings make their homes at the surface of the planet we know as Earth. The shapes that decorate Earth’s surface include a variety of landforms, including mountains and valleys, canyons and ridges, volcanoes, basins, hills, sand dunes, and moraines. Each landform is the result of one or more processes that create and change Earth’s surface.

As we begin Unit 2: Landforms,  students begin to look at ways to represent the features of Earth’s surface at smaller scales. We will work in three dimensions by creating desktop models and transfer the features in their models to a two-dimensional map. Along the way, they learn that symbols can represent landforms, structures, and other features of an area.

They continue their study of the landforms by investigating the effects of water running over Earth’s surface. The Grand Canyon is the focus of their investigations as they set up a model plateau in a stream table. As they observe the effects of water running over solid earth materials, they learn new landforms and vocabulary, including canyons, deltas, erosion, and deposition. We will design and set up investigations to study how changes made by people affect the processes of erosion, deposition, and stream flow.

A wonderful way to encourage your child to study outside of the classroom is to expose them to their natural environment through parks and natural deposition of particular places. Head outside after a rainstorm, what do you notice? Read books with the family to spark continuation of interests. If you have any questions or comments, please do not hesitate to contact me!
