5. ANTICIPATION GUIDE WITH YOUR RESEARCH GROUP, USE TABLE 1 TO ANSWER THE QUESTIONS. DO YOUR BEST, BUT DON’T WORRY IF YOU GET STUCK. WE’LL GO OVER THEM AGAIN LATER. LET’S TAKE 6 MINUTES

6. ANTICIPATION GUIDE Table 1: Conversion Factors 1 carat (ct) =2.000 x 10 -1 gram (g) 1 ounce (oz) = 1.822 x 10 1 pennyweight (dwt) 1 pound (lb) = 7.000 x 10 3 grains (gr) 1 stone (st ) = 4.900 x 10 3 scruple (s.ap) 1 grain (gr) = 3.240 x 10 -1 carat (ct) 1 pennyweight (dwt) = 1.555 x 10 0 gram (g) 1 scruple (s.ap) = 2.857 x 10 -4 pound (lbs)

8. REVIEW: KEY VOCABULARY INFORMAL DEFINITION IS MADE UP OF DIFFERENT PARTS. A WAY OF DOING THINGS THAT PEOPLE HAVE AGREED ON. HOW MANY TIMES THAT YOU SHOULD MULTIPLY SOMETHING BY ITSELF. TO USE A FORMULA TO WRITE A VALUE IN A DIFFERENT WAY. TO NOTICE SOMETHING. TO DO A PROCEDURE. TERM CONSISTS CONVENTION EXPONENTIAL EXPRESS OBSERVED OPERATION

9. MAKING COMPLEX CONVERSIONS

10. SOLVING THE PROBLEM IT’S ALL IN THE APPROACH

11. SOLVING THE PROBLEM DON’T BE FOOLED, IT’S EASY TO CRASH Video Reference: www.youtube.com/watch?v=X8Y2F1320QI

12. SOLVING THE PROBLEM AS SEEN IN THE ANTICIPATION GUIDE, IT BECOMES VERY EASY TO MAKE ERRORS DURING THE CONVERSION. THE KEY TO AVOIDING MISTAKES IS TO DEVELOP THE DISCIPLINE OF CARRYING UNITS WHEN DOING CALCULATIONS! UNITS ARE MULTIPLIED, DIVIDED AND OTHERWISE TREATED LIKE VALUES. WHEN THE PROBLEM IS SET UP CORRECTLY, UNITS WILL CANCEL LEAVING THE CORRECT UNITS.

13. EXAMPLE 1

14. EXAMPLE 2 Let’s say it takes 2.5 hours to go 227.5 miles, what’s you speed in mph?

15. LET’S TRY A CONVERSION

16. GROUP REFLECTION (IMPLICATION AND CONSEQUENCE QUESTION) BASED ON YOUR EXPERIENCE WITH THE ANTICIPATION GUIDE AND THE LAST FEW SLIDES DISCUSS WITH YOUR RESEARCH GROUP, WHAT WOULD BE THE CONSEQUENCE OF NOT INCLUDING UNITS AS PART OF CONVERSION CALCULATION? (3 MINUTES) COME TO CONSENSUS WITH YOUR GROUP AND CHOOSE ONE PERSON TO PRESENT YOUR GROUPS OPINION. WHEN CALLED UPON, USE THE SENTENCE FRAGMENT: “OUR GROUP CONCLUDES THAT FAILURE TO INCLUDE UNITS WHEN MAKING CONVERSION CALCULATIONS WOULD RESULT IN _______"

17. HOW TO SET UP THE PROBLEM USE THIS GRAPHIC ORGANIZER TO MAKE CONVERSIONS

18. NOW, LET’S TAKE THE TRAINING WHEELS OFF PROBLEM 3 FROM YOUR ANTICIPATION GUIDE AT $0.04 PER PENNYWEIGHT, HOW MUCH IS 1.5 LBS OF STARBUCKS COFFEE? $0.04 1 dtw 1.555 x 10 0 g $17.50 1.5 lb 2.000 x 10 -1 g 1 ct 3.240 x 10 -1 ct 1 g 7.000 x 10 3 g 1 lb

19. USE THIS PROCESS TO MAKE ANOTHER CONVERSION WITH YOUR RESEARCH GROUPS.

20. TRY THIS ONE WITH YOUR RESEARCH GROUPS 0.68 CT EMERALDS COST $173.40 ON THE WHOLESALE MARKET. HOW MANY LBS OF EMERALDS ARE REQUIRED TO BUY AN $11899 USED BMW? ($11899/BMW) X (0.68 CT EMERALDS /$173.40) X (1 GR/3.240 X 10 -1 CT) X (1 LBS/ 7.000 X 10 3 GR) = 2.057 X 10 -2 LBS EMERALDS /BMW

21. PARTING THOUGHT GROUPS OF ITEMS MAY ALSO BE EXPRESSED AS DECIMALS. 6 EGGS MAY BE EXPRESSED AS A HALF A DOZEN OR 0.5 DOZEN. FOR OUR CAKE, HOW MANY DOZEN EGGS ARE REQUIRED FOR THE RECIPE? (PLEASE USE SCIENTIFIC NOTATION.) 2.500 X 10 -1 DOZEN EGGS

22. WRAP UP: VOCABULARY PROVIDE AN INFORMAL DEFINITION FOR EACH OF THESE TERMS BASED ON THEIR USE IN THE CONTEXT OF THIS CLASS. CONVERT DISSIMILAR PHENOMENON RATIO UNITS

23. WRAP UP: SCIENCE SPEAK (VIEWPOINT QUESTION) DISCUSS WITH YOUR GROUP THE MOST DIFFICULT CONCEPT FROM THIS LESSON FOR 3 MINUTES. AGREE WITH YOUR GROUP ON THE MOST DIFFICULT CONCEPT AND CHOOSE ONE PERSON TO PRESENT YOUR GROUPS OPINION. WHEN CALLED UPON, USE THE SENTENCE FRAGMENT. "IN OUR OPINION, THE MOST DAUNTING CONCEPT WAS DETERMINED TO BE_______"

24. WRAP UP: REFLECTION (ELABORATING QUESTION) SPEND 5 MINUTES TO WRITE IN YOUR LEARNING JOURNAL. DESCRIBE THE MOST INTERESTING ASPECT OF THIS LESSON AND HOW THIS CONCEPT MIGHT BE PUT TO USE IN YOUR PERSONAL LIFE.
