"Thinking About Science Themes" covered in this article: Sometimes scientists study something that has already been studied. When scientists do this, they gather, read, and summarize all the research that has been completed. This process is often called a literature review. Scientists look at how other scientists researched the problem and then come up with their own research question and design an experiment to help answer their question. However, there are times when scientists do not have access to much previous research. When that happens, scientists first look at what general information is known, as well as the research that has been conducted on similar topics. Using that information, the scientists come up with their own research question and design an experiment to help answer it. You will learn that the scientists in this research did not have much previous research to examine prior to beginning their research. Therefore, they created new questions similar to research conducted by other scientists. Specific "Thinking About Science" Themes:"Thinking About Environmental Themes" covered in this article: Forests are filled with a variety of natural resources. Natural resources are parts of the natural environment that meet human needs such as wood for housing, plants for food and medicine, and water for drinking. Native and naturalized plants and fungi are collected from forests for medicinal, edible, decorative, or other reasons. Scientists estimate that 4,000–6,000 plant species worldwide are collected from forests for these purposes. Nearly 200 species are harvested from North American forests. Half of those species are in the forests of the southern Appalachian Mountains (figure 15). Some examples of medicinal plants are American ginseng (figure 16), goldenseal, slippery elm, and black cohosh. These are slow-growing, perennial forest herbs. The belowground material of these plants is the part mostly used for medicinal purposes. Specific "Thinking About the Environment" Themes:NSE Standards covered in this article:
