4. What’s wrong with this picture? Hepzibah, Lavinia, and Igor are each taking dangerous chances in their lab that only a mad scientist would take! Stop them before it’s too late! 1.Why is it a bad idea for Igor to be eating his sandwich in the lab and drinking out of a lab beaker? 2.Predict what will happen to Lavinia as she holds a container over this flame. What do you see in the picture that could help her avoid this? 3.Hepzibah is doing one thing right. What do you think it is? What dangerous things is she doing?

11. What is Technology? n Is there a difference between computer literate and technologically literate? n i.e. does technology require computers?

12. What is Technology? n List the 5 things that come to mind when you think of “technology”

13. What is Technology? n List the 5 things that come to mind when you think of “technology”

14. Technology… takes place when people use their knowledge and creativity to extend their abilities, satisfy needs and wants, and solve problems

15. What is Technology? n The practical use of human knowledge to extend abilities, satisfy needs and wants, and to solve problems

16. The Development of Technology n Nomadic era - Hunting and gathering n Agricultural age – plow and sickle n Development of villages where there was farming and raising livestock n 1700’s = Industrial Age n Muscle power was replaced with machine power of the steam engine n Transportation systems originated n Today = Information age n Began in the mid 1800’s n Development of transistor and computer

17. Scientific Method n A good experiment tests only one variable at a time Same experiment without the variable Variable Control Factor that is being tested. Ideally there is only one.

18. The Design Process n Are you an inventor? n Are you innovative? n Design is the process of making new things by planning

19. Invention n Improving and changing a technology that already exists n The process of designing new products Innovation

20. Interactive CD Activity n Visit the “Designed World” Interactive Lab on the Student CD to explore more about some of the technologies in our lives.

21. Principles and Elements of Design n “The Elements of Design” and “The Principles of Design” on the Student CD

22. The Design Process n Much like the scientific method n However you may skip around from step to step http://www.doe.mass.edu/frameworks/scitech/2001/standards/strand4.html

23. The Design Process 1. Identify a Need or Define the Problem 2. Gather Information 3. Develop Possible Solutions 4. Model the Solution 5. Test and Evaluate the Solution 6. Refine the Solution 7. Communicate your Ideas

24. Identify a Need or Define the Problem n Criteria – Things that the product must do or include n Constraints – Limits placed on the design and the designer

25. Gather Information n “No need to reinvent the wheel’ n Research, visit, internet search, talk to people, etc.

26. Develop Possible Solutions n Think of as many design ideas as possible n “Brainstorm” Brainstorming n Process in which group members suggest ideas out loud as they think of them n Ideas are usually written down on a board in front of the group n All advantages and disadvantages of each idea is discussed

27. Model the Solution n Two dimensional and pictorial drawings/sketches n Scale models n Appearance models n Functional models n Prototype n Computer Simulation

28. Test and Evaluate the Solution n Does it do what it is supposed to? n Is it safe to use? n Will it last as long as it needs to? n Is the cost within acceptable limits? n Is it comfortable to use? n Does it have a pleasing appearance? n Does it stay within the criteria and constraints?

29. Refine the Solution n If changes are needed after testing and evaluations you may improve your solution

30. Communicate your Ideas n Designers have to prove their ideas are worthy of manufacturing n Drawings, charts, prototypes, and dialogue are necessary

31. Who Designs Solutions Engineer n Person who uses his or her knowledge of science, math, technology, and communication to solve technical design problems

32. A New Generation of Engineering n Manufacturing Engineers Increase productivity n Aerospace Engineers Aircrafts n Materials Engineers Develop products for strength, weight, etc n Environmental Engineers Design cleaner production methods n Computer Engineers Hardware and software designs

33. Scientific Units n Read Scientific Measurements Packet n Answer Section Review #1-3

34. Scientific Units? meter (m) liter (L) u 1mL = 1 cm 3 gram (g) seconds (s) degrees Celsius (C) u 0 o K = -273 o C u Room temp = 25 o C u Human = 37 o C n Length - n Volume - n Mass - n Time - n Temperature -

35. Matter n Anything that has a mass and a volume

36. Mass n The amount of matter in an object n Depends on number and type of atoms

37. Weight n Measure of attraction due to gravity n On moon weight = 1/6 of Earths

38. Area n Amount of surface occupied by an object n length x width

39. Volume n Amount of space occupied by an object n L x W x H n 1 cm 3 = 1 ml H L W

40. Density n Amount of matter that occupies a given space n mass / volume

43. PerAreaVolumeMassWeightDensity NameCm 2 mlgNg/ml

44. Scientific Method n Can you think of any theories or laws? n Incoming freshman n Evolution n Big bang Theories & Laws

45. Scientific Method Theory Logical explanation based on gathered data What is a theory? Theory of Gravity

46. Scientific Method Theory tested many times (and proven true) What is a law? Law

47. Scientific Method n What goes up must come down… n Right? Theories & Laws

48. Scientific Method n If further observations disprove a theory it must be changed or discarded Theories & Laws What happens if something goes up but doesn’t come down?
