The Core Technologies PURPOSE OF LESSON To familiarize students with the core technologies (engineering resources) – the building blocks of the designed world – by having students identify and describe the core technologies as they are applied in the designed world. U3c-L1

The Core Technologies U3c-L1 Write these down: What is a function? The action for which a thing exists What is an application? A use to which something is put

Do NOT copy everything – get key words All examples are not necessary – write those that sum it up to you. Listen while you take notes. NOTE TAKING: U3c-L2

The technology of putting together mechanical parts to produce, control, and transmit motion. Mechanical Technology Example applications: Gear systems in a car transmission, Brakes on a bicycle, Agitator in a washing machine, Latch on a door. Springs in vehicle shocks U3c-L2

The technology of putting mechanical parts and materials together to create supports, containers, shelters, connectors, and functional shapes. Example applications: Legs on a chair, City water tower, Swimming pool, Roadways and Bridges, Bicycle spokes Airplane wing, Satellite antenna disc. Structural Technology

U3c-L2 The technology of producing, storing, controlling, transmitting and getting work from electrical energy. Example applications: Power plant generator, Flashlight, Electric motor in a can opener, Doorbell, Electric heater, Hair dryer. Electrical Technology
