Today we are going to continue our study of Weathering and Erosion. Students will learn the different types of Weathering (Mechanical and Chemical) as well as the difference between erosion and deposition. Students will start by working on key vocabulary from the Weathering chapter. We will also complete labs and other activities to reinforce the concepts presented throughout the unit.
BIG IDEA:
Weathering is a continuous process that results in the formation of soil and the development of landforms.
GPS Standards for Earth Science: (CURRENTLY WORKING ON) HIGHLIGHTED WORDS TELL US WHAT WE WILL DO AND HOW WE WILL DO IT.
S6CS1 Students will explore the importance of curiosity, honesty, openness, and skepticism in science and will exhibit these traits in their own efforts to understand how the world works.
S6CS3 Students will use computation and estimation skills necessary for analyzing data and following scientific explorations.
S6CS4 Students will use tools and instruments for observing, measuring, and manipulating equipment and materials in scientific activities.
S6CS5 Students will use the ideas of system, model, change, and scale in exploring scientific and technological matters.
S6CS6 Students will communicate scientific ideas and activities clearly.
S6CS9 Students will investigate the features of the process of scientific inquiry
S6CS10 Students will enhance reading in all curriculum areas.
S6E5 Students will investigate the scientific view of how the earth’s surface is formed.
c. Classify rocks by their process of formation.
g. Describe soil as consisting of weathered rocks and decomposed organic material
h. Explain the effects of human activity on the erosion of the earth’s surface.
i. Describe the methods for conserving natural resources such as water, soil and air.
Essential Questions:
What are the different types of weathering and how can the be demonstrated?
Why is weathering important?
Activities:
Complete Reading and discussion weathering from Chapter 10 Section 1
Look at different types of Weathering with Weathering Stations.
Vocabulary
Weathering-the process by which rock materials are broken down by the action of physical and chemical processes Mechanical Weathering-the breakdown of rock into smaller pieces by physical means Abrasion-the grinding and wearing away of rock surfaces through the mechanical action of other rock or sand particles Chemical Weathering-the process by which rocks break down as a result of chemical reaction Acid Precipitation-rain, sleet, or snow, that contains a high concentration of acids. Differential Weathering-the process by which softer, less weather resistant rocks wear away and leave harder more weather resistant rocks behind. Soil Conservation-a method to maintain the fertility of the soil by protecting the soil from erosion and nutrient loss. Erosion-the process by which wind, water, ice, or gravity transport soil and sediment from one location to another. Soil-a loose mixture of rock fragments, organic material, water, and air that can support the growt of vegetation. Parent Rock-a rock formation that is the source of soil. bedrock-the layer of rock beneath the soil. Soil Texture-the soil quality that is based on the proportions of soil particles. soil structure-the arrangement of soil particles. Humus-the dark organic material formed in soil from the decayed remains of plants and animals. Leaching-the removal of substances that can be dissolved from rock, ore, or layers of soil due to the passing of water.
