1. 1. What is the line graph about? 2. At what age do teens have the least number of cell phones? 3. How many cell phones do 15 year-olds have? 4. About how many cell phones do 16.5 year- olds have? 5. How many more cell phones do 18 year-olds have than 16 year-olds? Science Starter Monday 8/31/15

2. SPI 0807.Inq.3: (Interpret Data) Notes Mandatory Task (Tennessee Requirement) SPI 0807.Inq.3-Interpret and translate data into a table, graph, or diagram. Science Data Interpretation: 4 Steps (Summarized Version) Step 1: Carefully examine it. Step 2: Look for patterns/trends Step 3: Figure out what the question is asking. Step 4: Find the answer (may be in the pattern/trend)

3. SPI 0807.Inq.3: (Interpret Data) Notes  (1) Closely examine the table, graph, or diagram What do you notice when you examine this table? 12 months City X Avg Temp City Y Avg Temp Avg monthly temp (in Celsius) Science

4. SPI 0807.Inq.3: (Interpret Data) Notes  (2) Look for patterns in the way the data is organized and displayed City X-Lowest temps (coldest) are Dec, Jan and Feb What patterns do you see with this data? January February December City Y-Lowest temps (coldest) are also Dec, Jan and Feb Science

5. SPI 0807.Inq.3: (Interpret Data) Notes  (2) Look for patterns in the way the data is organized and displayed June, July, and Aug are the highest temps (hottest) for both cities What other patterns do you see with this data? June July August Science

6. SPI 0807.Inq.3: (Interpret Data) Notes  (2) Look for patterns in the way the data is organized and displayed For both cities the lowest temps happen in the coldest winter months June July August For both cities the highest temps happen in the hottest summer months January February December Also for both cities moderate temps temps occur in spring and fall Spring Fall Science

7. SPI 0807.Inq.3: (Interpret Data) Notes  (2) Look for patterns in the way the data is organized and displayed Are there any other things that you notice? Look at the temps of these two cites… …which city is generally warmer? City Y is warmer City X is cooler Science

8. SPI 0807.Inq.3: (Interpret Data) Notes  (3) Read over the question and determine specifically what it is asking There is nothing in the table about wind speed. So letter A probably is not the right answer Science

9. SPI 0807.Inq.3: (Interpret Data) Notes  (3) Read over the question and determine specifically what it is asking There is nothing in the table about humidity So letter B probably is not the right answer Science

10. SPI 0807.Inq.3: (Interpret Data) Notes  (3) Read over the question and determine specifically what it is asking There is nothing in the table about rainfall So letter D probably is not the right answer Science

11. SPI 0807.Inq.3: (Interpret Data) Notes  (3) Read over the question and determine specifically what it is asking Cities on the equator are closer to the sun, so these cities are generally hotter than cities in other areas of our planet So letter C is the correct answer. City X is generally colder than City Y, so it is logical to assume that City X is further from the equator Science

13. SPI 0807.Inq.3: (Interpret Data) Notes Different types of charts, tables, and graphs Science Tables  Tables/charts are used to organize exact amounts of data and to display numerical information.  Tables do not show visual comparisons.

14. SPI 0807.Inq.3: (Interpret Data) Notes Different types of charts, tables, and graphs Science Pie Charts  Best used for comparing parts to a whole  The total amount should equal 100%  A pie chart is a circular chart divided into sectors  Works well for comparing 6 or fewer items, but more than six items becomes difficult to view and interpret

15. SPI 0807.Inq.3: (Interpret Data) Notes Science Pie Charts: Examples

16. SPI 0807.Inq.3: (Interpret Data) Notes Different types of charts, tables, and graphs Science Bar Graph  Bar graphs are used to compare facts. The bars provide a visual display for comparing quantities in different categories  Bar graphs help us to see relationships quickly.

17. SPI 0807.Inq.3: (Interpret Data) Notes Science Bar Graph: Example  Example: A survey of student's favorite after-school activities was conducted at school The table shows the results  Note: Since the data is not changing over time, a line graph would not be best for displaying this data. A bar graph is better.

18. SPI 0807.Inq.3: (Interpret Data) Notes Different types of charts, tables, and graphs Science Line Graph  Line graphs are used to display data or information that changes continuously over time.  Line graphs allow us to see overall trends such as an increase or decrease in data over time.
