Slope forest: In Jocassee Gorges: Temperate rain forests of the Blue Ridge, page 17; Finally, the spray community gives way to the forests that dominate the slopes above it. A typical slope forest is shown in Figure 15 behind Turtleback Falls, one of the two cascades above Rainbow Falls. Turtleback Falls is a favorite cascade sliding spot....; By Dirk Frankenberg and Stephanie Walters.

Climate on north- and south-facing slopes: In Roan Mountain Highlands, page 16; Figure 14 shows the interior of a higher elevation forest showing the abundance of birches and beeches that typify the northern hardwoods community. This photo also shows and interesting feature of climate differences on north and south facing slopes. The...; By Jennifer Godwin-Wyer and Dirk Frankenberg.

From northern hardwood to spruce-fir forest: In Elevations and forest types along the Blue Ridge Parkway, page 12; The highest elevations of the Blue Ridge are occupied by an evergreen forest of spruce and fir that looks like the great conifer forests of northern Maine and Canada. The transition from northern hardwoods to spruce fir forest is easy to see from a distance...; By Dirk Frankenberg.

Walk the line: This lesson demonstrates the effects of changing the slope and y-intercept on the graph and equation of a line.; Format: lesson plan (grade 8–12 Mathematics); By Carol Huss.

Investigating linear equations: Using a graphic calculator to compare the slope and y-intercept of lines to understand the slope-intercept form (y = mx+b) and what effect each has on a line.; Format: lesson plan (grade 9–12 Mathematics); By Misty Jarman.

Seaward slope of a dune: In Large sand volume barrier islands: Environmental processes and development risks, page 14; Figure 13 shows the seaward slope of large dunes near the beach in Fort Macon State Park. These dunes are more than 50 feet high and form a relatively continuous barrier that protects areas behind them from salt spray. The seaward dune face shown here is rather...; By Dirk Frankenberg.

To be or not to be... linear: The student will determine the correlation between two variables. They will graph ordered pairs on a coordinate plane, determine a best fit line, find slope and intercepts, and write the equation of a line. This lesson plan is geared for both 8th grade math and algebra.; Format: lesson plan (grade 8–12 Mathematics); By Kyle Gorton.

Personal trainers: Working with slope: In CareerStart lessons: Grade eight, page 2.2; In this lesson, students make calculations based on slope and answer questions about slope (rate of change).; Format: lesson plan (grade 9 Mathematics); By Debbie Brooks, Peggy Dickey, and Jan Sullivan.

Bouncing ball experiment: In this experiment students should be in groups of 3. Students will drop a ball from different heights and measure the corresponding bounce. Since each group will use a different ball, they will generate different sets of data. They will be asked to discuss and compare their linear function with that of their classmates. They should practice measuring the ball bounce before they begin to collect data.; Format: lesson plan (grade 9–12 Mathematics); By alicia jones.

Dune erosion on Bear Island: In Hurricanes on sandy shorelines: Lessons for development, page 10; Figure 7 shows that not all of the barrier islands are flattened when hurricanes make landfall over them. This photograph shows the beach and seawardmost dunes of Bear Island after five hurricanes battered them in two years. The remnants of dead maritime thicket...; By Dirk Frankenberg.

CareerStart lessons: Grade eight: This collection of lessons aligns the eighth grade curriculum in math, science, English language arts, and social studies with potential career opportunities.; Format: (multiple pages)

Mid-tide beach: In Small sand volume barrier islands: Environmental processes and development risks, page 5; Figure 3 shows the mid-tide beach with evidence of recent accretion of sand to the upper beach. Look closely at the beach profile and you will see that the surface is slightly higher and more covered with shells both above and below the relatively shell-free...; By Dirk Frankenberg.

Burying Nags Head Woods: In Natural and human impacts on the northern Outer Banks, page 7; Figure 6 is a view to the northwest, showing the Run Hill Dune migrating over Nags Head Woods. Notice the steep slope of the southwestern face of the dune, formed by the strong northeast winds.; By Blair Tormey and Dirk Frankenberg.

A high-elevation creek: In Roan Mountain Highlands, page 17; Figure 15 shows another view of the high-elevation northern hardwoods community with the headwaters of a typical mountain drainage creek. Note the relatively large size and square shape of the stones in the creek. This is what we would expect in small headwater...; By Jennifer Godwin-Wyer and Dirk Frankenberg.

Bikes going up the slope, Haleakala National Park, HI: Bikes going up a slope, Haleakala National Park, Hawaii. Tourists can take tours by bicycle to see the Haleakala Volcano, including early morning tours that allow visitors to view the sunrise from the peak of the volcano. The road is tortuous, with many blind...; Format: image/photograph

Irrigating the fields: In Rice farming and rural life in Vietnam, page 4; Wet-rice farming requires that plants stand in water during early stages of their growth. The water then must be drained away before the rice fully ripens for harvesting. Bamboo wheels such as the one shown here aid this process of water management in places...; By Lorraine Aragon.

Maritime forest: In Evidence of rising sea level: Coastal erosion and plant community changes, page 13; Pine forests are not the only type of forest that salt marshes can invade during periods of rising sea level. Figure 12 shows a salt marsh in an area between beach ridges on Bogue Banks extending laterally into a maritime forest of live oaks and other hardwoods....; By Dirk Frankenberg.

Subtidal seafloor: In Evidence of rising sea level: Coastal erosion and plant community changes, page 9; Salt marshes do well in irregularly flooded areas, but rising sea level continuously converts these areas into regularly flooded habitats and then into a new seafloor. Some marsh plants, especially smooth cordgrass, can tolerate the first of these conversions,...; By Dirk Frankenberg.
