Teacher's Answer Key
Answers will vary for this activity. However, students should use information they learned in the essay to describe forest research.
Sentences provided below and suggested definitions, however answers will vary for this activity.
1. Sentence: There are numerous environmental concerns facing society today and most of them center on ways of maintaining an ecological balance in our world. OR There are numerous environmental concerns facing society today and most of them center on ways of maintaining an ecological balance in our world.
2. Definition: Problems, struggles, issues, effects of altering the environment in our society
1. Sentence: Some researchers focus on urban forests, product safety and human health, and forest products consumption. OR For example, researchers might analyze the effects of an urban forest on air quality and water quality in the city.
2. Definition: Numerous trees, forested park, or forest located in an urban, developed, or city/town area.
1. Sentence: These researchers might examine the economic impacts of forest disturbances, such as insect infestations.
2. Definition: Something that causes a interference or disruption in a forest therefore causing harm or damage to all or part of the forest ecosystem.
1. Sentence: Research Center in Lake City , Florida , where new techniques for naval stores production were developed. Naval stores refer to the storing of products extracted from raw pine gum from living pine trees.
2. Definition: Creating and stocking up goods made from the sap/gum of pine trees.
1. Sentence: Most forest hydrologists attribute the first watershed studies in the U.S. to the Wagon Wheel Gap Project in Colorado , which began in 1909 and ended in 1926. OR Over the last century hundreds of forest watersheds have been monitored and used in watershed studies. (And numerous other options.)
2. Definition: Watersheds are areas where people get water. There are numerous watersheds through the U.S. They are natural areas that help store water for later human use/consumption.
1. Sentence: The U.S. Forest Products Laboratory made significant advances in recycling paper in the late 1960s and again in the 1990s. OR Recycling helps extend the functional life of wood fiber and helps reduce the buildup of waste in landfills. (And numerous other options.)
2. Definition: Taking old materials and reusing them to create new products.

Assessment 2: Test
1. What is Timber Management Research?
Timber management research deals with trying to find answers to the challenges of forest regeneration (renewal), improving growth and yield, and protecting forests from insects, disease, and fire.
2. What is the Forest Product Laboratory?
The Forest Product Laboratory opened on April 1, 1910 and its primary goal was to discover new technologies for producing wood products while creating less logging waste.
3. What major research development helped the naval store industry?
The Lake City Research Center found that nearly half of the chipping labor could be saved with no loss in gum production by spraying sulfuric acid on a fresh cut to prolong the flow of gum. This one research development saved the naval stores industry about a million dollars in 1951.
4. What benefits resulted from Wood Preservative Research?
Wood preservatives extended the life of railroad ties, thus saving the railroad companies money in the long run. The early research on wood preservatives reduced the demand for railroad ties by 75 percent and lead to the use of preservation methods for other wood products as well, such as fence posts, and various building materials.
5. Explain what the Wagon Wheel Gap Project in Colorado studied.
Wagon Wheel Gap was a cooperative project with the Weather Bureau and the Forest Service. This project was to be a study of the effects of timber removal on water yield or stream flow and erosion under the conditions of the central Rocky Mountains.
6. What were some of the major research developments in recycling?
Major developments in recycling included: discovering ways to recycle paper products to create new “recycled” paper products, discovering new techniques for removing contaminants, especially adhesives to create new recycled paper products, and discovering a new process for recycling paper that lowered the cost to the producer.
7. Why is forest product research so critical?
Forest products research is critical to the social and economic well being of people on a global level, because the demand continues to increase on a natural resource that continues to decrease.
Assessment 3: Reflection
Answers will vary depending on student surveys. Students should turn in a list of the 10 or more people that they surveyed, along with their completed tally sheet and 2 Histograms.
