  1. Is It Really “Great”? • Discuss the following with the people at your table: • What criteria could be used to determine if an invention should be considered “great” • List several of the “greatest inventions of all time” and as a table rank the top 5 Day 1 Drill Engagement

  2. How did you do it? • Which of the criteria did your group use to identify the top five inventions? • Was there one criterion that held “more weight” in your decision? Engagement

  3. Top 10 Inventions • Read the article “Top 10 Greatest Inventions Ever” – 5 minutes • Identify 3 items that you feel were left off of the list or would come in at # 11, 12, and 13. • On a fresh sheet of paper, list these items and write a short explanation for why you feel they should be there. Do this in the same “style” as the author. Exploration

  4. The Most Important Invention of All Time • Your criteria was based on important aspects of our lives. • These include: • Social • Economic • Educational • Political • Safety • Health Copy these categories and make a note of how the internet has impacted each Day 1 Drill Explanation

  5. The Most Important Invention of All Time • Society – easier communication w/ friends family • Economic – buy/sell easier, larger audience, jobs • Education – online classes, easier research • Politic – ads, info, fundraising • Safety – information, privacy issues • Health - online records Explanation

  6. Communication systems allow information to be transferred from: • Human to human (telephone) • Machine to human (digital thermometer) • Human to machine (TV remote) • Machine to machine (atm computer to bank computer) Explanation

  7. New Technologies • Result from: • Demands • Values • Interests • Of • Individuals • Industries • And Society Explanation

  8. New Technologies • Result from: • Demands • Values • Interests • Of • Individuals • Industries • And Society Explanation

  9. Societal Expectations • Meeting societal expectations is the driving force behind the acceptance and use of products and systems. • Acceptance is based on: • Whether it does its designed job. • How well it accords with various economic, political, cultural, and environmental concerns. Explanation

  10. The process is often slow. • Many inventions and innovations have evolved by using slow and methodical processes of tests and refinements. • Experimentation is sometimes the only way • Edison’s Light Bulb Explanation

  11. The First Practical Light Bulb • Edison developed the first practical light bulb in 1879 • In 1880, he created a bulb that has all of the essential features of a modern bulb. • An incandescent filament in an evacuated glass bulb with a screw base 1880 1893

  12. The Filament Was Key • Creating the filament was the most critical factor. • It had to glow when an electrical current passed through it. • It possessed a high electrical resistance • It had to last for a long time. Explanation

  13. Many, Many Tries • Edison and his team experimented with thousands of different filaments just to find the right materials to glow well and last a long time. Explanation

  14. Discussion • What were the demands, values, and interests of individuals, industries, and society that led to the development and acceptance of electric lighting? Explanation

  15. Potential and Kinetic Energy • In the past, an invention or innovation was not usually developed with the knowledge of science. Friction Elasticity Aerodynamics Explanation

  16. Information is shared in many forms including: • Numbers • Words • Symbols • Sounds • Images Explanation

  17. Symbols • The use of symbols, measurements, and drawings promotes clear communication by providing a common language to express ideas. Explanation

  18. Extension Activity • You will be using a website that describes over 100 inventions. Not all of them are “high impact”. • You are to create a one-page fact sheet about a “high impact” invention. • Which list on the next page consists of “high impact” inventions?

  19. Airplane Telephone Vacuum Packed Canning Solar Cell Elevator Highways Seat belts X-ray machine Etch-a-Sketch Astroturf Tennis Instant Mashed Potatoes Hacky Sack Sandwich Skateboard Zamboni High or Low Impact Extension

  20. Answer in a sentence • Where on the list of the “Top 100 Inventions” do you think your selected topic fits? • Notebook checks begin today! Day 3 Drill

  21. Is It Really “Great”? • Discuss the following with the people at your table: • What criteria could be used to determine if an invention should be considered “great”. It should: • 1 _________________________________ • 2 _________________________________ • 3 _________________________________
