Is that technology?
The Engineering Design Process! Intro to Sci. and Tech. 6th Grade U3L1&2
Technology… The application of science for practical purposes Can be simple or complex
Engineering The application of science and math to solve real-life problems and improve our quality of life Chemical engineers- Develop chemical products Electrical engineers – Use computers and machines Biomedical engineers - Design medical devices like X-rays and prosthetics
Science vs. Engineering Study of natural world involves designed, man-made world
MATH is important in engineering (read p. 118, third pgh) (do #8 & 10) Advances in science can lead to new or improved technology through engineering MATH is important in engineering (read p. 118, third pgh) (do #8 & 10) In solving real-world problems, engineers think about… (pg. 119, all) CONSTRAINTS – limitations Ex. Only so much budget, laws of physics, etc. TRADE-OFFS – giving up one advantage to keep another Ex. Cost vs. strength of bridge
What skills make a good engineer? 1. Thinking skills Thinking creatively Coming up with new ways of doing things Thinking methodically Thinking in an organized way and paying attention to details 2. Technical skills Using math and models Prototype = a test model of a project Using technology Tools, equipment, software, etc. 3. Research skills To see how problems have been solved in the past, new materials, processes
Good morning, 6th Grade! Please turn in your vocab (if you haven’t already!) Then pick up an envelope from the front desk. You and your partner can share an envelope. Try and put the steps in your envelope in order!
Lesson 2 – Methods of Analysis
1. Risk-benefit analysis Compares unfavorable effects (risks) and favorable effects (benefits) Risks Benefits
2. Life Cycle Analysis Evaluation of materials & energy needed for technology – done to account for environmental effects Manufacture? Transportation? Sale? Use? Disposal? Manufacture Transportation Sale Use Disposal
3. Pugh Chart Table used to compare features of multiple items Feature
Effects of Technology Technology can have expected and unexpected effects on … Society The environment The economy Technology can have favorable (good) or unfavorable (bad) Do pg. 133
Trade-offs Accepting risks in exchange for benefits Giving up one benefit to gain another
