Soil
It all depends on soil! Over the years, much of our precious topsoil eroded into ditches and waterways. Today, farmers are working hard to improve the land.

What’s Your pH?
Students learn how pH affects nutrient uptake in plants. Students then measure the pH in soil samples and determine if/how their soil should be modified through soil amendments. Developed by National Ag in the Classroom, this grade 9-12 resource is linked to curriculum outcomes.
Properties of Soils (Gr. 9-12)
In this hands on activity, students examine what happens to different types of soil when mixed with water. Next, students explore the components of soil (sand, silt, and clay) and examine how these particles effect water retention and air space in the soil. Developed by National Ag in the Classroom, this grade 9-12 resource is linked to curriculum outcomes.
Properties of Soils (Gr. 6-8)
Students learn that soil is made of different components such as sand, silt, and clay and examine how these particles effect water absorption and air space in the soil. Developed by National Ag in the Classroom, this grade 6-8 resource is linked to curriculum outcomes.
Plant Nutrient Deficiencies (Gr. 9-12)
Students will discover that just like humans, plants also need a balance of essential nutrients to be healthy. Students will also diagnose plant nutrient deficiencies, define fertilizers as a source of plant nutrients, and appreciate that fertilizers help to restore a healthy balance of soil nutrients for crops. Developed by National Ag in the Classroom, this grade 9-12 resource is linked to curriculum outcomes.
Plant Nutrient Deficiencies (Gr. 6-8)
In this lesson, students learn about fertilizers and their role in plant nutrition. Students will also learn about the need to replenish nutrient balance in agricultural soils, and discuss how people and crops can suffer from nutrient deficiencies. Developed by National Ag in the Classroom, this grade 6-8 resource is linked to curriculum outcomes.
In Search of Essential Nutrients (Gr. 6-8)
In this lesson plan, students learn about essential elements of humans and plants. Students will compare and contrast the essential nutrient requirements of humans and plants and discover the sources of nutrients for plants. Developed by National Ag in the Classroom, this grade 6-8 resource is linked to curriculum outcomes.
Digging in to Nutrients
In this lesson plan, students will learn about the different nutrients plants need to grow, and how plants obtain nutrients. Students will also learn how farmers replenish soils with necessary nutrients, and current issues faced by the agricultural production industry. Developed by National Ag in the Classroom, this grade 6-8 resource is linked to curriculum outcomes.
