Students who demonstrate understanding can:
MS-ESS2-1 Develop a model to describe the cycling of Earth's materials and the flow of energy that drives this process. [Clarification Statement: Emphasis is on the processes of melting, crystallization, weathering, deformation, and sedimentation, which act together to form minerals and rocks through the cycling of Earth’s materials.]
MS-ESS2-2. Construct an explanation based on processes have changed Earth’s surface at varying time and spatial scales.
MS-ESS2-3. Analyze and interpret data on the distribution of fossils and rocks, continental shapes, and seafloor structures to provide evidence of the past plate motions.
MS-ESS2-4. Develop a model to describe the cycling of water through Earth’s systems driven by energy from the sun and the force of gravity.
Studying erosion and deposition will lead students to the exploration of landforms and how they are formed. Stream tables using different types of sand and soil help students observe how meandering streams and braided streams through erosion lead to the creation of canyons, deltas, plateaus, mesas, and buttes. Scientific investigations illustrate the effects of erosion, deposition of soil and how our planet is constantly changing. As geomorphologists, students learn how mountains are formed and how to classify the different types of valleys as U shaped or V shaped. When students review the core, mantle, and crust of the earth, they understand how these forces continue to impact the earth.
Annenberg Learner Rock Cycles
Annenberg Learner presents an easy to understand description of the rock cycle. Types of rocks are illustrated with photographs. To reinforce this concept student can create their own virtual rock collection. How rocks change is shown with several animations. There is a diagram for the rock cycle. In addition there is a short assessment at the end of the activities.
Geology for Kids
Five chapters are included in this study of geology, Examining the Soil; Earth Rocks, and Landforms; The Earth Inside; An Introduction to Erosion; and Erosion by Water Processes. Each chapter contains examples and information about the topics covered. If you like to use songs with your lessons, there are several from which to choose such as Ballad of the Fossils and Our Earth Inside Out.
Kinetic City Shape It Up
After studying about the changes to the earth, play this game to test your knowledge. You are presented with a challenge to change this picture to this picture by choosing a force of nature and a time span.
PBS Erosion and Weathering
Launch the lesson and view photographs and explanations about erosion, weathering, and erosion management. There are supplemental materials including a NOVA video of the Grand Canyon and animations about caves and the rock cycle. Also included are the science standards related to the lesson.
Study Jams: Landforms
Finding resources and preparing lessons are at the top of every teacher's list. For elementary math and science teachers looking for videos or slide shows to introduce or augment a topic, check out Study Jams. These short and concise clips, featuring contemporary animated characters, present the right amount of information that students can easily digest and remember. In mathematics the core standards are covered from numbers to probability. Science topics also include the main themes of life science, physical science, and earth and space science.
Weathering and Erosion - Discovery
This video is a nice introduction to weathering and erosion. Popup labels further point to features in the scene.
Photographs and descriptions of a variety of landforms will assist students in learning and identifying these formations.
1. How can you observe a mineral wear away?
All you need are some rocks, chalk and a plastic jar to experiment with weathering.

2. Stream Table
Prepare stream tables for your students to use for experimentation.
♦ Prepare the stream table. Cut a hole in the bottom of each turkey pan near one of the shorter sides.
♦ Mix up the soil mixture to be used in the stream tables. The mix should contain 3 parts sand, 1 part humus, and 1 part gravel. Add soil mixture to each of the stream tables, on the side opposite the hole.
♦ Prepare the cups. Pierce a small hole in the bottom of half of the colored plastic cups and a large hole in the bottom of the other half of cups. Mark a line on the inside of the cup near the top of the cup that represents an even amount of water (such as 1, 1 ½, or 2 cups). This will ensure that students always use the same amount of water. Put a bucket under the drain hole.(Source: Friends of the Chicago River)
Have the students develop a hypothesis and conduct experiments using the student handout and their science journals.
