Chapter 2 Figure 21 Controlled field experiment to measure the effects of deforestation on the loss of water and soil nutrients from a forest Vnotched dams were built into the impenetrable bedrock at the bottoms of several forested valleys left so that all water and nutrients flowing from each valley could be collected and measured for volume and mineral content These measurements were recorded for the forested valley left which acted as the control site Then all the trees in another valley the experimental site were cut right and the flows of water and soil nutrients from this experimental valley were measured for 3 years.

Identifying the big questions. Science, Matter, Energy, and Systems. Scientists use a variety of methods to learn about how the physical world works.. The methods fall into a general process.. Science is used to search for order in nature.. &. Matter and Energy. . Main Idea. You will be able to . demonstrate. . an understanding of the properties of matter and energy and their interactions.. [8 questions on STAAR]. Matter has measurable physical properties. . Chapter 2. Figure 2.1. Controlled field experiment to measure the effects of deforestation on the loss of water and soil nutrients from a forest. V–notched dams were built into the impenetrable bedrock at the bottoms of several forested valleys (left) so that all water and nutrients flowing from each valley could be collected and measured for volume and mineral content. These measurements were recorded for the forested valley (left), which acted as the control site. Then all the trees in another valley (the experimental site) were cut (right) and the flows of water and soil nutrients from this experimental valley were measured for 3 years..
