  15. 15. How did I use it in class?• I used my data table to plot points on a line graph.• I used my previous knowledge of increments, intervals, axes and trend lines to display my data• Line Graphs can be used to show relationships (Time vs Position) or patterns(2 cm/second)• They show data (visually) in a way that you can understand it with great detail and analyze it better than a data table (a bunch of numbers)
  16. 16. How can I use it outside the science classroom?• If I experiment again, my data can be shown on a line graph to be albe to identify trends, rise in data, drop in data, or any other patterns.• If I am given a line graph, I can find trends, relationships, independent and dependant variables.• I can use line graphs to show (position vs time) relativity or recurring trends and/or data.• I can understand changes in stock markets or my GPA using the graphs provided to me (rise, drop or no change).

  37. 37. 11-29-11 Revising Modelsusing Data Analysis
  38. 38. What did I learn today?• We learned about the four basic types of models.• Mental Models- Use words• Mathematical Models- Use math• Physical Models- Physical objects that explain the relationship between things• Computer Models- Uses many different mathematical models and mental models• We also learned that the Learning Cycle is Data Analysis Identify Patterns Creating Models How Test Prediction.• An object was move towards the origin and there are two origins Time Origin and Position Origin.• A data line can have an increasing or decreasing speed while moving in a negative or positive direction.• A graph can have many different visual representations for one data set and can have different orientations to view the data.
  39. 39. How did I learn it?• I learned it when we analyzed the graphs in 5.2• We tested our class model for 4.5 and they were proved to be too general
  40. 40. How did I use it in class?• I formulated a better explanation and model for 5.2 and I made my model not too general or too specific.• I replicated a better understanding of the idea of models and how there are many types.
  41. 41. How can I use it outside the science classroom?• I can formulate a better understanding if the object is moving towards the origin or away from it in a negative or positive direction.• I can determine if an object is decreasing speed or increasing speed based on my new model (revised in 5.2)
  42. 42. 11-30-11How different orientationsand movement can affect a graph
  43. 43. What did I learn today?• I learned the difference between standard deviation and a trend line.• Standard deviation is the average distance from the average (as Dennis said).• We used the motion sensors which used infrared rays to detect motion and create a graph using the interactive software.• We learned that walking gradually can be very hard when you are trying to show constant speed on a graph.• We learned to follow specific directions when we were trying to copy one of our classmates motion by using our classmates’ advice and looking at the graph which is displayed on the overhead.
  44. 44. How did I learn it?• I learned walking gradually can show constant speed if you walk at a certain pace without increasing or decreasing speed.• Graphs can have bumps to show unusual movement.• If an object moves slowly then increases speed, the graph will look like a curve up.• If an object starts away from the sensor and then moves towards the sensor, they graph will be a downhill data line.
  45. 45. How did I use it in class• I assisted and gave advice to the “victim” that had to go out of the room.• I helped by giving directions and key points such as speed, increase, decrease, and position.• I used it to make procedures for graphs 3 and 4 from 5.5
  46. 46. How can I use it outside the science classroom?• I can gelp people devop a gradual pace for athletic coimpetitions.• I can determine a mental graph by looking at someone’s speed and orientation.• Then, I can use that to create a mental graph to identify common patterns.
  47. 47. 12-01-11 How different orientationsand positions can determine the way a graph looks
  48. 48. What did I learn today?• I learned that sometimes words aren’t enough to be able to give someone directions.• I learned to be specific and turn the graph’s data line in words of motion.• You need to turn what you understand while looking at a graph into directions that someone can follow to copy the motion displayed by the data line in the graph.
  49. 49. How did I learn it?• I learned by trying different motions with speeds and positions to match the graph from 5.5.• I learn by using the motion sensors and trying to copy different graphs using the interactive software.
  50. 50. How did I use it in class• I used my skills to help my classmates move in front of the motion sensor so they could copy the motions presented in an another graph.• I used my skills to develop an understanding of movement and how the motion sensor is the origin and you have to “recreate” the motion displayed by the data line in the graph.
  51. 51. How can I use it outside the science classroom?• I can use my skills of visualizing a graph to real life and determine how to speed is increasing and any patterns.• I can use my skills of recreating motion to develop the necessary directions to recreate a situation or a visual (line graph).
