Tuesday: Chickasaw Challenge

1. Tuesday: Chickasaw Challenge • Create a multiple choice question for Law of Conservation of mass • Create a dichotomous key for the three pictures below.

2. Class Pledge • We Will… • Work Hard NOT because we have to but because we WANT to for our own success and future. • We Can… • Achieve excellence through hard work and motivation • We All… • Work together to reach our greatest potential • Our Future… • Is college bound!!!

3. Today’s Objectives SWBAT identify and apply the procedures needed to test the design features of a prototype. Objective: (SPI 0607.T/E.2)Evaluate a protocol to determine if the engineering design process was successfully applied.

4. What’s Up Today? Importance: We live in a world of ever changing technology?? Society benefits when engineers apply scientific discoveries to better the designs that are created.

5. How many of you want to engineers or designers, or teachers?? Write down what you want to be!!

6. Vocabulary Engineer: people who design and build new forms of technology. Engineers use science to make the world around them better.

7. Pick a Piece of Technology

8. Steps of the Engineering Process Ask Improve Imagine Critique Plan

9. An Iguana Plays Cards Inside • Ask • Imagine • Plan • Critique • Improve

10. Take 3 minutes and in your group identify that technology.

11. Step 1: Engineering Design Process Ask: Identifying and Researching a Need Oil will run out so we need a car that can run without it

12. Step 2: Engineering Design Process Imagine: Developing Possible Solutions how to solves the problem. • Flying car • Car that runs on battery • Car that runs on air

13. Step 3: Engineering Design Process Plan: Making a Prototype • MODEL OF THE FLYING CAR

14. Step 4: Engineering Design Process Critique: Testing and Evaluating • TEST IT and SEE what works and what doesn’t work • TOO SLOW

15. Step 5: Engineering Design Process Improve: Modifying and Retesting the Solution FIGURE OUT A WAY TO make it go faster….

16. Sum It Up!! • Is this process infinite or finite? • Ask: question.. • Imagine: come up with solutions • Plan: create model • Critique: what’s good / bad • Improve: how can I make it better?

17. Let Do Another Example Together • Ask: HOW TO GET BEST LOUD, clear, wireless, headphones • Imagine: -jess phones, wireless phones • Plan: Make my model • Critique: test them • Improve: fix the problems

18. Which Step??… A farmer came up with a new invention, a machine that could identify the different types of corn. After building and trying to sell his invention, the farmer found that very few people want to buy his machine. What step of the design process did the farmer NOT follow?

19. Which Step?? Roger and James were creating a new device. After spending countless hours researching and brainstorming, they came up with their best solution. What should Roger and James do next?

20. George Lucas had a “Eureka!” moment. He had a brilliant idea to design and make light sabers like in Star Wars. What should George do after building his prototype light saber?

21. Mini Project.. You are going to Create your Own Invention!! Ask: Create an invention that answers one of these problems.

22. Homework Due Thursday: • Write a ½ page description of your invention. Answer the following question. • Described in detail your invention and what it does. • What problem does it solve? • Who will it help?

24. Chickasaw Challenge • Fill In the Blanks: • Ask, _____, Plan, _______, ________. • What is a prototype? • How would you be able to tell which fossil is oldest?

25. Today’s Objectives SWBAT identify and apply the tools needed to test the design features of a prototype. Objective: SPI0807.T/E.1: Identify the tools and procedures needed to test the design features of a prototype.

26. Don’t Forget about our Competition • What were some of the inventions??

27. The Engineering Design Process • The engineering design process involves an ongoing series of events that incorporate: • Design constraints • Model building- build a prototype • Test • Evaluate • Modify and Re-Test

28. Steps of the Engineering Process Ask Improve Imagine Critique Plan

29. Procedures for Planning Your Prototype • Always research and brainstorm before you design your prototype. Take into consideration things that you have seen work in the past for similar prototypes. • Think about possible design constraints • Money • Time • Space • Availability of parts

30. Procedures for Evaluating Your Prototype • Make sure you thoroughly examine your prototype after you test it to ensure that it meets your criteria and expectations • Does the design work as planned? • Does the design effectively solve the original problem? • How can the design be improved?

31. Tools to Test for Strength • Spring scale-measures force • Ex: weight is a measurement of the force of gravity Weights of varying masses Pressure/force

32. Tools to Test for Length Ruler Meter stick Tape measure

33. Tool to Test for Time Stopwatch

34. Tools to Test for Volume Graduated cylinder Beaker

35. Tools to Test a Prototype for Hardness Hammer

36. Paper Airplane Design Lab In groups of two, we will complete the paper airplane engineering design lab.

37. Chickasaw Challenge • Complete the half slip of paper for the Chickasaw Challenge.. • Remember that classes who are quiet and working get the group points..

38. Rapid Review.. Mini quiz • Telephone.. • What are the 5 steps for this invention using the engineering design process

39. A closer Look at the Design Process.. What does it mean to be an engineer?

40. Lab: Part 1 • 10 Minutes.. • Create two designs that you want to fly • Complete Procedure questions: 1, 2, & 3

41. Test Your Plane.. • 1 Person Flies at a time.. • You are not allowed to step across that line when you are finished… • You need to measure the distance. • Complete data chart

42. What are the Behavior Expectations when outside?

43. Question • Answer questions: what do you need to improve on your design?? Why did you choose to change this. • Improve Plane Design!! (7 minutes) • When you are ready you are going to fly for number two..

44. 7 minutes • Complete the Conclusion questions!!1 • I need a paper from EVERYONE for lab credit..

45. Exit Ticket • Pretend that you are creating a jumpsuit that is designed to keep people warn in cold weather.. • Tell me what you would do at each step of the 5 design process. • Example: Ask:

46. Chickasaw Challenge: Thurs. 1. What is the first thing that should be done when you are trying to engineer a product? 2. What should I do to my prototype after I create it? 3. Does the engineering design process ever end? Why or why not?

47. Today’s Objectives SWBAT recognize and differentiate between assistive and adaptive bioengineered products. SWBAT identify and describe intended benefits of technology. SWBAT identify and describe unintended consequences of technology.

48. Technology • Technology refers to the product or processes that are designed to serve our needs • There are two major types: Assistive Adaptive

49. Bioengineered Products Bioengineered products are created from the use of technology (they are not natural but rather man made) to alter or improve living things

50. Assistive Bioengineered Products Assistive– technology that helps!!! Helps living organisms but does not change them permanently These products assist people, but they are not permanent Assistive products are created specifically for disabled people
