Evaluating Greatness in Inventions: Criteria and Impact

This engagement activity prompts participants to explore the concept of "greatness" in inventions. Groups discuss criteria for evaluating inventions and rank them, identifying reasons why certain innovations are essential. Using a structured approach, they analyze how inventions have influenced various societal aspects including social, economic, educational, political, safety, and health dimensions. The activity encourages critical thinking about invention significance and its lasting impacts on human life, culminating in a fact sheet project on a selected high-impact invention.

Presentation Transcript

  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 _________________________________
