Thurs May 28

• Used Dry Ice
  
  • Let use play with the dry ice and several other items, figure something out about carbon dioxide
    
  • Filled aquarium with CO₂ but could not see it . Will try it sometimes to show that CO₂ gas is denser than air so it stays in the container.
  • Student make copies of a machine that made soap bubbles filled with CO₂
  • Showed the triple point of CO₂ using a pipette (have direction).

• Modeling
  • Each proivded an example of modeling, I explained how I use an area surrounded by tables as the volume of a gas, students as gas particles, how fast they walk is their temperature and how many times they hit the wall is the pressure. Model the gas particle as a student and how the ideal gas works.
