Description

From TeachEngineering - Students gain a basic understanding of the properties of media—soil, sand, compost, gravel—and how these materials affect the movement of water (infiltration/percolation) into and below the surface of the ground. They learn about permeability, porosity, particle size, surface area, capillary action, storage capacity and field capacity, and how the characteristics of the materials that compose the media layer ultimately affect the recharging of groundwater tables. They tes

Performance Expectations

MS-ETS1-1   Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions

MS-ETS1-2   Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

MS-ETS1-3   Analyze data from tests to determine similarities and differences among several design solutions to identify the best characteristics of each that can be combined into a new solution to better meet the criteria for success.

MS-ESS3-3   Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment.

MS-ESS2-4   Develop a model to describe the cycling of water through Earth's systems driven by energy from the sun and the force of gravity.
