The lesson exposes students to how groundwater is polluted as well as explores common pollutants. Students will complete a lab which will provide a visual on how groundwater is contaminated. Lesson 1/4
After analyzing how groundwater is polluted in the first lesson, students will be introduced to aquifers and how they play a role in filtering groundwater that has been polluted. Lesson 2 of 4.
Students will model the atomic structure of common elements found in soils, determine an atom's valence electrons, draw Lewis electron dot diagrams, and discuss the basic principles of element bonding.
Plants need specific nutrients in specific amounts to maintain healthy growth. This lesson begins to investigate elements and their relationship to plant growth and overall crop yield.
Soil pH plays a key role in cation exchange capacity of soil, and plants ultimate ability to uptake nutrients available from the soil. Since 14 of the 17 essential plant nutrients are found in the soil it is crucial these elements are held in the root zone and accessible when plants need them for growth. Healthy soils will have a high cation exchan…
This lesson investigates the periodic table, atomic structure, and electron configuration. The activities in the lesson build to help students understand soil pH and nutrient availability in the culminating project and throughout the course.
How do rocks become soil? Students will research, document, and demonstrate a chemical or physical weathering process by which sedimentary rock breaks down to begin the formation of soil.
What physical properties of matter are measured in soil testing?
What elements make up the soil around us? Students will investigate the basics of atomic structure and discover how scientists use a soil sample to determine soil type.
Review the basics of sedimentary rocks and model the rock cycle; beginning with mineral sediments and working through all stages of the cycle, and rediscover the role of weathering and erosion!
Students will perform tests on soil samples to determine the USDA classification and soil type; including ribbon testing, and water holding capacity.
The Earth's surface is covered with rocks. In this lesson, students will learn how to identify the three distinct kinds of rocks present: igneous, metamorphic, and sedimentary rocks.
Minerals are the basic building blocks of rock and provide the foundation of the rock cycle, a model that describes the formation, breakdown, and reformation of a rock as the result of sedimentary, metamorphic, and igneous processes.
