Credits • Discovery Education provided the video clips from the “Weathering and Erosion” video.http://streaming.discoveryeducation.com/index.cfm • Slide 6 & 16 are video clips taken by Dr. Echol Marshall from the MathScience Innovation Center. • Slide 28 : Where is EcoGrid used?EcoGrid can be used as either a temporary or permanent ground reinforcement. It is used to reinforce lawns and other grassy areas to prevent mud and damage to the ground. Once laid ecogrid can be filled with stone, earth or seeded. When the grass has grown EcoGrid becomes invisible but still resists wear and compression. Ecogrid is perfectly suited to pathways, parking lots or driveways and has numerous sporting applications such as equestrian facilities and golf courses. EcoGrid is provides excellent ground support and prevention from erosion.http://www.terrafirmenterprises.com/ecogrid.html • All other photos have the credit on the page except for those taken by Rhonda Hawley, Educator, MathScience Innovation Center or ones from clip art.
