Sames Physical Science

Essential Question:

• How can data be organized to help demonstrate information?
  

Objectives:

• To see the what elements exist in the air we breath.
  To practice visualizing data.
  

Agenda:

• Warm-up: AIR INGREDIENTS?
  • Air(dry) is mostly only four different types of gases, there are also four other elements floating around out there in measurable quantities (between 0.001818% and 0.000055% of all air).  What do you think they might be?
• Review-mini-quiz
  
• Create a bar graph to represent the elements of the air.  Your graph must include the following:
  
  • A descriptive title
    
  • An x & y axis with proper labels
    
  • Proper scales for both axes
    
  • All elements listed are represented
  • Use the following information:
    • Nitrogen — N₂ — 78.084%
      Oxygen — O₂ — 20.948%
      Argon — Ar — 0.934%
      Carbon Dioxide — CO₂ — 0.031%
      Other — 0.0020%
