1. Engineering Resources Lesson 3-3 Core Technologies

2. Purpose  To familiarize students with the engineering resources (core technologies), the building blocks of the designed world.  To identify and describe the core technologies as they are applied in the designed world.

3. Engineering Resources  A technology system is a group of resources (subsystems) working together to solve problems and extend human capabilities.

4. Engineering Resources  Mechanical technology  The technology of putting together mechanical parts to produce, control, and transmit motion.  Examples: transmission gears, bicycle brakes, latch on a door.

5. Engineering Resources  Structural Technology  The technology of putting mechanical parts and materials together to create supports, containers, shelters, connectors, and functional shapes.  Example: legs on a chair, city water tower, roads, bridges.

6. Engineering Resources  Electrical Technology  The technology of producing, storing, controlling, transmitting, and getting work from electrical power.  Example: power plant generator, electric can opener, hair dryer.

7. Engineering Resources  Electronic Technology  The technology of using small amounts of electricity for controlling, detecting; and information collecting, storing, retrieving processing and communicating.  Example: thermostat, medal detector, TV

8. Engineering Resources  Fluid Technology  The technology of using fluid, either gaseous (pneumatics) or liquid (hydraulic) to apply force or to transport.  Example: plumbing in your home, air brakes, air in a tire

9. Engineering Resources  Optical Technology  The technology of producing light; using light for information collecting, storing, retrieving, processing, and communicating; and using light to do work.  Example: light-emitting diode, magnifying lens, laser cutting tool.

10. Engineering Resources  Thermal Technology  The technology of producing, storing, controlling transmitting and getting work from heat energy.  Example: toaster, hot water heater, jet engine

11. Engineering Resources  Biotechnology  The technology of using, adapting, and altering organisms and biological processes for a desired outcome.  Example: stain-eating enzymes in detergents, bacteria leaching metals from ore, altering plant genes to produce better crops.

12. Engineering Resources  Materials Technology  The technology of producing, altering, and combining materials.  Example: making paper from wood, drilling holes in wood, making aluminum foil from ore

13. Assignment  In your group, you will each come up with one example of a core technology. Each group will be assigned one core technology. You will use the internet to print out a picture of your example. There will be at least 6 examples per group. You will share your examples with the class.
