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. “The most incomprehensible thing about the world is that it is comprehensible.”. – .

Intensive Properties: depend on type of matter, not amount. Density: mass/volume. Module H Unit 1: Matter Lesson 1: Introduction to Matter Matter - anything that has mass and takes up space. Matter makes up the materials around you. Mass - the amount of matter in an object. Even air has mass. Matter and Energy What is matter? Matter and Energy What is matter?
