Introduction In the design of engineering projects‚ one of the most important soil properties of interest to the soils engineer is permeability. To some degree‚ permeability will play a role in the design of almost any structure. For example‚ the durability of concrete is related to its permeability. In designs that make use of earthen materials (soils and rock‚ etc.) the permeability of these materials will usually be of great importance. Soils are permeable (water may flow through them) because they

1 Experiment Membrane Transport Objectives ► Referring to energy‚ what two ways can substances enter a cell? What is active transport? What is passive transport? How is osmosis related to diffusion? How can we demonstrate active transport? How can we demonstrate Brownian movement? How can we demonstrate diffusion (2 ways)? How can we demonstrate osmosis (3 ways)? In terms of relationships between substances‚ how can we define “hypertonic”‚ “isotonic”‚ and “hypotonic”? What is the relationship
