  14. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Let’s also do some basic math and algebra review.

  15. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) ½ = _____ First… What is this fraction expressed as a decimal to two places?

  16. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) ½ = 0.50 First… Expressed as a decimal to two places; one-half is equivalent to…

  17. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) ½ = 0.50 Next… What is this decimal value expressed as; a PERCENT to two places ?

  18. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) ½ = 0.50 = 50.00 % Next… Expressed as a PERCENT to two places – one-half is equivalent to…

  19. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) ¼ = ____ % ⅟₁₀ = ____% ⅛ = ____ % In your teams… In the next 4 minutes… express the following as a; PERCENT to THREE decimal places… http://www.online-stopwatch.com/full-screen-stopwatch/

  20. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) ¼ = ⅟₁₀ =______% ⅛ = ______ % In your teams… In the next 4 minutes… express the following as a; PERCENT to THREE decimal places… 25.000 %

  21. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) ¼ = ⅟₁₀ = ⅛ = ______ % In your teams… In the next 4 minutes… express the following as a; PERCENT to THREE decimal places… 25.000 % 10.000 %

  22. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) ¼ = ⅟₁₀ = ⅛ = In your teams… In the next 4 minutes… express the following as a; PERCENT to THREE decimal places… 25.000 % 10.000 % 12.500 %

  23. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) In another area we need to review the “constructs” of “rectilinear graphs”

  24. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) For a rectilinear graph or a coordinate graph we need a pair of axis. Can you name the horizontal axis?

  25. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) The horizontal axis is called the “X” axis. X

  26. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) For a rectilinear graph - can you name the vertical axis?

  27. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y The vertical axis – is called the “Y” axis. X

  28. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y When someone wishes to plot a “data point” on a rectilinear graph –or- coordinate graph… … it is done with “coordinates” X

  29. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y The “coordinates” tell us where to put the data point. This type of graph usually has at least TWO variables for each data point. X

  30. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y Either the values for “X” are “dependent” variables making “Y” values “Independent” variables…, or it can be just the opposite – the scientist decides. X

  31. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y Therefore; if “Y” is changing (dependent variable) because of what you are specifically doing as a scientist in the study (independent variable); X

  32. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y Another way to say this is: “Y” (dependent variable) is the “effect” while X” (independent variable) is the “cause” X

  33. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y we link them together by using what is called an “ordered pair.” (___, ___) X

  34. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y For an “ordered pair” – we call the value for “X” the ….? (___, ___) X

  35. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y For an “ordered pair” – we call the value for “X” the …. … abscissa (___, ___) X

  36. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y For an “ordered pair” – we call the value for “Y” the ….? (___, ___) X

  37. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y For an “ordered pair” – we call the value for “Y” the …. … ordinate. (___, ___) X

  38. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y What is the abscissa and ordinate for the ordered pair on the graph? (_X, _Y_) X

  39. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y What is the abscissa and ordinate for the ordered pair on the graph? ( 3 , 4 ) X

  40. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y As practice for the upcoming L1023 Dry Lab; let’s try one of the ordered pair data points. ( 3 , 4 ) X

  41. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y Given this part of the table: 70% 50% Gas Composition Percentage (%) 30% 10% X 4.5 3.5 Time (billions of years ago) - BYA

  42. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y Given this part of the table: … plot the first two ordered pairs of N2(g) (nitrogen gas) 70% 50% Gas Composition Percentage (%) 30% 10% X 4.5 3.5 Time (billions of years ago) - BYA

  43. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y Given this part of the table: … plot the first two ordered pairs of N2(g) (nitrogen gas) 70% 50% Gas Composition Percentage (%) 30% 10% X 4.5 3.5 Time (billions of years ago) - BYA

  44. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y What makes a “cumulative” graph different – is the data points “cumulate” (add together) 70% 50% Gas Composition Percentage (%) 30% 10% X 4.5 3.5 Time (billions of years ago) - BYA

  45. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y If you are asked to also plot the carbon dioxide gas (CO2) ordered pairs for the same times we’d get… 70% 50% Gas Composition Percentage (%) 30% 10% X 4.5 3.5 Time (billions of years ago) - BYA

  46. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y Carbon dioxide gas (CO2) ordered pairs PLUS Nitrogen gas’ values or ordered pairs… 70% 50% Gas Composition Percentage (%) 30% 10% X 4.5 3.5 Time (billions of years ago) - BYA

  47. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y For 4.5 BYA: Carbon dioxide gas (CO2) is 80%. THAT is added to N2 ‘s 10% to get 90% for the two gases cumulatively! 70% 50% Gas Composition Percentage (%) 30% 10% X 4.5 3.5 Time (billions of years ago) - BYA

  48. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y For 4.0 BYA: Carbon dioxide gas (CO2) is 20%. THAT is added to N2 ‘s 35% to get 55% for the two gases cumulatively! 70% 50% Gas Composition Percentage (%) 30% 10% X 4.5 3.5 Time (billions of years ago) - BYA

  49. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y The nice thing about a “cumulative” graph [is] it can answer a question like: 70% 50% Gas Composition Percentage (%) 30% 10% X 4.5 3.5 Time (billions of years ago) - BYA

  50. U3: The 4 “Spheres”L1023 – ACT (Data Representation Dry Lab) Y “Did the two gases CO2 and N2 together decrease in the Earth’s atmosphere 4.0 BYA, and if so… was it either one in particular? 70% 50% Gas Composition Percentage (%) 30% 10% X 4.5 3.5 Time (billions of years ago) - BYA
