Inside every house is a lot of science. Show this eye-opening two-part series to your students so they can see for themselves how engineering principles, high-tech materials, and proven construction techniques keep the forces of nature at bay and homeowners cozy and content. On the site and in the lab, host Steve Hanneman makes a heavy topic light because learning is easier when watching is fun.This video highlights scientific aspects of concrete, steel, wood, and nails – and the forces that impact them. Experiments done on the building site and at materials testing labs investigate the strengths of concrete, rebar, and engineered lumber; the chemical properties of Portland cement and galvanized nails; and the effects of dead load and live load, torque and shear induced by wind and earthquakes, and Bernoulli’s Principle as it relates to the effects of tornadoes on roofs. Microscope and infrared imaging plus animations give extra angles of insight. So do field trips to a concrete batch plant, a tree farm to study sylviculture, and a sawmill to see how computerized cutting and sorting are done.
