Students will use the Engineering Design Process to develop and construct an aeroponic garden to grow a food crop. Students will develop and apply an understanding of plant anatomy and physiology related to plant growth and ultimately discuss the possibilities and limitations of using vertical farming to produce our food. Grades 9-12

In this lesson, students will use their knowledge of solutes, solvents, and parts per million to analyze fertilizer options that meet plant nutrient requirements while evaluating costs associated with managing plant nutrients. Grades 9-12

Students will recognize that fertile soil is a limited resource, describe the role fertilizer plays in increasing food productivity, distinguish between organic and commercial fertilizers, describe how excess nutrients are harmful to the environment, and identify different sources of nutrient pollution. Grades 9-12

Students explore the meaning of essential elements and use periodic tables to compare the elements that are essential to people and plants. Students discover where in the environment plants obtain each of their essential elements. Grades 9-12

In this lesson, students will test for plant-available soil nitrogen and learn how farmers use this test to precisely match fertilizer application to meet crop needs and reduce the amount of nitrogen left in the soil. Grades 9-12

Students will recognize that plants, like people, require essential nutrients to be present in the right amounts in order to be healthy, use reference materials to diagnose plant nutrient deficiencies, define fertilizer as a type of “food” for plants, and appreciate that fertilizers are used to replenish nutrients in agricultural soils. Grades 9-12

Students examine different types of soil that have been mixed with water and allowed to settle. Next, they work with a soil model to investigate its components (sand, silt, and clay) and learn how the properties of these components affect the passage or retention of water through the soil and the amount of air in the soil. Grades 9-12

Students observe soil ecosystems to investigate how human impact affects the biodiversity of soils using the Simpson's Index of Diversity. Then, students conduct an investigation using field corn to determine how the introduction of nitrogen fertilizers impact soil microorganisms and biodiversity. Grades 9-12

Students identify the importance of plants to human life by surveying their home and neighborhood for plant products used for medicine, aesthetics, fuel products, fiber, and food. Grades 9-12

In this lesson students will measure the pH of a soil sample and learn how pH affects the availability of nutrient uptake by plants. Students will determine if and how their soil pH should be modified through the application of soil amendments. Grades 9-12
