What type of graph to make?

• Option 1 Bar graph
• Good for comparing data for several items or
  events
• Option 2 Line graph
• Best for displaying data that change
• Option 3 Pie chart
• Good for displaying data that are part of whole.

7
What type of graph should it be?Bar graph, line
graph or pie chart

• The composition of calcite is 48 oxygen, 40
  calcium and 12 carbon.
• There were 27 German shepherds, 16 Basset hounds,
  7 Beagles, and 20 Golden retrievers at the dog
  show.
• As the temperature of the lake water increases,
  the amount of oxygen dissolved in the water
  decreases.
• 75 out of 100 students study for science every
  night.
• The amount of students enrolled in science, art,
  PE, and math 1.
• As pressure in a container increases the
  temperature also increases.

Steps to make a bar graph

• Number the increments for the RV on the y-axis
  (side of graph) Label the y-axis and include
  units
• Write categories for MV on x-axis (bottom of
  graph)
• Decide how wide each bar should be (what fits on
  the paper)
• The height of the bar should correspond with
  number on y-axis.
• Put a descriptive title on graph

How to make a line graph

• Determine the increments x-axis. Check your data
  (MV) for the highest and lowest numbers. Label
  x-axis and include units.
• Determine the increments y-axis. Check your data
  (RV) for the highest and lowest numbers. Label
  y-axis and include units.
• Plot your data
• Make the best fit line. It should include most
  of your data point, but points way outside of
  data should be ignored.
• Finish up by including a title.

How to make a Pie chart

• Convert data to percentages.
• 2/10 20 5/10 50 3/1030
• 2)Convert percentages to degrees of the circle.
• 20 X 360 72
• 50 X 360 180
• 30X 360 108
• 3) Use protractor to measure angles in a circle.
  
• 4) Label each piece in the circle.
• 5) Give pie chart a title

Today in Science

• September 20th In 1952, Alfred Hershey and
  Martha Chase publish a report confirming DNA
  holds hereditary information.
• Their experiment used the T2 bacteriophage,
  which, like other viruses, is just a crystal of
  DNA and protein. It can reproduce when inside a
  bacterium such as E. coli.
• Hershey and Chase were seeking an answer to the
  question, Is it the viral DNA or viral protein
  coat (capsid) that is the viral genetic code
  material which gets injected into the E. coli?
• What type of spinning tool did they use to
  separate the virus protein from the bacteria?

• The meal was a simple affair, consisting of a bit
  of unleavened bread made of einkorn wheat, one of
  the few domesticated grains used in the Iceman's
