Savvy soil: The students will compare and contrast the physical characteristics of three soils: clay, humus, and sand. They will create double bubble maps and list poems about the soils.; Format: lesson plan (grade 3 Science); By Karen Smith.

Salt marshes: In Wetlands of the coastal plains, page 15; The single most important ecological feature of salt marshes along coastal rivers is their immersion/exposure cycle. The lower the marsh, the longer the surface is immersed in tidal waters. Low marshes in North Carolina are dominated by smooth cordgrass (; By Dirk Frankenberg.

Developing salt marsh: In Evidence of rising sea level: Coastal erosion and plant community changes, page 12; In case you were doubtful that salt marshes can really invade and take over forested areas, I have included Figure 11 to lay these doubts to rest. In this photograph you will see a developing salt marsh with the trunks and roots of the preexisting forest still...; By Dirk Frankenberg.

Inquiry: You are an earthworm: In CareerStart lessons: Grade six, page 3.5; This lesson for grade 6 will help students understand the cycling of matter. Students assume they are earthworms and learn by asking questions about their life processes. The lesson also introduces career possibilities in the soil science field.; Format: lesson plan (grade 6 Science); By April Galloway and Christine Scott.

Soil Sampling: Students will learn how to sample soil to be analyzed for nutrient and lime requirements for proper plant growth.; Format: lesson plan; By Douglas Best.

Archaeological soils: In Intrigue of the Past, page 2.11; Students will determine components of a soil sample and evaluate how archaeologists use soils to interpret sites.; Format: lesson plan (grade 8 Science)

Plant power: Students will plant their own seeds in potting soil and measure plant growth. Before the students' plants are visible above the soil, students will explore the parts and functions of classroom plants and compare growth between the classroom plants. Using the weather channel website, students will predict weather the day's weather conditions are excellent, good, or poor for plant growth.; Format: lesson plan (grade K–1 Mathematics and Science); By Rhonda Hathcock.

How do pumpkins grow?: Book project: This is an integrated science and language arts lesson plan. Students will create individual books that illustrate how pumpkins grow.; Format: lesson plan (grade 1 Visual Arts Education and Science); By Marty Britt.

This section should be begun only after completion of Soil and erosion unit: Section 1.; Format: lesson plan (grade 9–12 Science); By Amy Robertson.

Stone Mountain: In Lonely mountains: The monadnocks of the inner Piedmont, page 12; Quartzite is not the only erosion-resistant rock that has formed monadnocks on North Carolina's Piedmont. Another major rock type — granite — has also been responsible for monadnock formation. Granite is a granular rock made primarily of feldspar...; By Dirk Frankenberg.

After the burn: In Forests and fires: The longleaf pine savanna, page 11; Figure 10 shows the forest after the controlled burn illustrated in Figures 8 and 9. There are now signs of wire grasses here because the stems have been burned, but the roots and rhizomes are alive and well under the soil surface. Look back at; By Dirk Frankenberg.

Tidal creek: In Cape Fear estuaries: From river to sea, page 9; This photo shows conditions just a few yards away from the shoreline.
