  1. Engineering, Technology & Science

  2. What comes to mind when you hear the word “technology?”

  3. Technology in a Bag • What is technology? • What does your technology do? What problem does it solve? • How else could you use it? • What materials are used to make it? • What other material could be used to make it?

  4. What is technology? Technology is: • Anything human-made or used to solve a problem or to fulfill a desire Technology can be an object, system or a process. • Can you identify a technology in this room that is a: • System • Process

  5. What can you do with a spoon? • What is an alternative function for this spoon? • If you were to think about redesigning this spoon so that it functioned better as a ______, what you change and why? • Who does this kind of work? Who uses their knowledge of science, materials properties and ergonomics to design technologies?

  6. Science, Technology, Engineering Science: • A body of knowledge • Seeks to describe and understand the natural world and its physical properties • Scientific knowledge can be used to make predictions • Science uses a process--the scientific method--to generate knowledge Technology: The body of knowledge, processes, and artifacts that result from engineering Almost everything made by humans to solve a need is a technology Examples of technology include pencils, shoes, cell phones, and processes to treat water Engineering: • Design under constraint • Seeks solutions for societal problems and needs • Aims to produce the best solution given resources and constraints • Engineering uses a process--the engineering design process--to produce solutions and technologies http://www.mos.org/eie/

  7. Comparison of typical processes Scientific Inquiry 1.) Observation and form a question 2.) Hypothesis & procedure 3.) Conduct an experiment 4.) Refine hypothesis and experiment again 5.) Form a conclusion and communicate it RESULT: Facts and theories Engineering Design 1.) Define the problem and resources available 2.) Develop a design 3.) Test the design 4.) Modify the design and test again 5.) Analyze the design and use or market it RESULT: Products and processes

  8. Engineering at work… • Ms. Campbell-Klett wants to put on display some of the Rainbow Lab Cylinders that her students have made in the 9th grade physical science in the large display cases near the Trojan head. • What is the problem? • In order to solve this problem, what do you need to know?

  9. Tower Activity Construct a tower to hold up a student rocket, the tower must be: At least 2 feet tall Structure must support a stapler for 10 seconds Cannot test the structure until the deadline is reached (30 minutes) and cannot be anchored Supplies your group may use: • 1 pack of 100 index cards • Scotch tape • Scissors

  10. Tower Activity 30 minutes

  11. Tower Activity • What is similar about these solutions? • What is different about them? • After testing, what would you do if given the chance to improve your tower?

  12. Action Words • What are some action words that describe what you did during the design process?

  13. Rocket lab redesign • Ms. Campbell-Klett wants to find a way to make the film canister rockets go higher. Brainstorm ideas in your lab groups for how this could look.

  15. Engineering Design Process Goal: To solve a problem by developing or improving a technology http://www.mos.org/eie/

  16. Engineering Design Process Ask What is the problem? What have others done? What are the constraints? http://www.mos.org/eie/

  17. Engineering Design Process Imagine What are some solutions? Brainstorm ideas. Choose the best one. http://www.mos.org/eie/

  18. Engineering Design Process Plan Draw a diagram. Make lists of materials you will need. http://www.mos.org/eie/

  19. Engineering Design Process Create Follow your plan and create it. Test it out! http://www.mos.org/eie/

  20. Engineering Design Process Improve Talk about what works, what doesn't, and what could work better. Modify your design to make it better. Test it out! http://www.mos.org/eie/

  21. Engineering Design Process ASK • What is the problem? • What have others done? • What are the constraints? IMAGINE • What are some solutions? • Brainstorm ideas. • Choose the best one. PLAN • Draw a diagram. • Make lists of materials you will need. CREATE • Follow your plan and create it. • Test it out! IMPROVE • Talk about what works, what doesn't, and what could work better. • Modify your design to make it better. • Test it out! http://www.mos.org/eie/
