Finding out how things work is one of the main goals of any scientist and can often lead to new technology or understanding. Learn how things work with tips from a science teacher in this free video series on science facts and information.
There are 9 videos in this series:
Electricity is generated by introducing conducting wire, usually copper or aluminum, to a magnetic field. Learn more about how electricity is generated from a math and science teacher in this free video on electricity.
Iron is generally found near the surface and is mined, in the form of iron oxide, with the use of large machines. Find out how iron is mined from a math and science teacher in this free video on iron.
Nuclear energy works in much the same way as traditional energy, except it requires less fuel to work and has harmful byproducts. Discover how nuclear energy works from a math and science teacher in this free video on nuclear energy.
A trebuchet is an ancient weapon that was used in battles to hurl large objects, often to break down walls. Learn how a trebuchet works with tips from a math and science teacher in this free video on weapons.
A shock absorber works to stop the unpleasant oscillations that occur on cars, trains, buses and other vehicles. Find out how shock absorbers work with tips from a math and science teacher in this free video on shock absorbers.
Transistors are based mostly on silicon cut into slices and made into semi-conductors which are then exposed to special chemicals. Discover how transistors work with tips from a math and science teacher in this free video on transistors.
Water springs are created when water is filtered through permeable rock in the ground and then flows downhill until it reaches ground level. Learn about how water springs work with tips from a math and science teacher in this free video on water spring.
The Richter scale works by allowing scientists to measure the size and intensity of an earthquake. Find out how the Richter scale works with tips from a math and science teacher in this free video on earthquakes.
Renewable resources are products that can be produced by the earth without running out. Find out what renewable resources are with tips from a math and science teacher in this free video on renewable resources.
Science is the driving force in most of the discoveries and inventions of the last several hundred years. Proposing a theory and proving or disproving it with careful experiments not only improves everyday life by producing everyday products, but it also improves general knowledge of how things work. While many high school and college students dread chemistry or physics class, it is the basic principles taught in these classes that help make improvements in the world. In this free video series on how things work, an experienced math and science teacher explains a variety of science facts. Learn how electricity is generated and how iron is mined. Find out how nuclear energy, transistors and water springs work. Discover what renewable resources are, and learn about how the Richter scale measures earthquakes.
