What is Engineering The word engineer originates from the Latin term ingenerare, meaning to invent, to create or to regulate It is the professional art of applying scientific principles to every day things to help make life easier

Engineer vs. Scientist Scientists Engineers Deviations between engineers and scientists arise through the differences in the ways both apply their educations in mathematical and natural sciences to their work Scientists Engineers Use their education to acquire new knowledge Use their education to develop usable devices, structures and processes Seek to know Aim to do

What is a Civil Engineer? One who improves the quality of life through the production of infrastructure Buildings, bridges and other structures Highways Dams and levees Water treatment plants, waste disposal This infrastructure must be safe, functional, elegant and economically sound

Why We Need Civil Engineers Make sure our human habitat is livable Make sure we use resources wisely Sustainable development Help maintain our competitiveness in the global economy Increase productivity

Pretty Amazing! A WATER BRIDGE .. OVER A RIVER!!!

Activity – Penny Boats Construct your boat using only one piece of the heavy duty aluminum foil provided. Predict how many pennies your boat will hold: _______________ Slowly add pennies to your boat. Once water enters the boat, or if any part of the boat touches the bottom of the container, your turn is over. The last penny added will not count in the total amount held.
