    2. When your mom makes Kool-Aid she uses ½ cup 
       of sugar. When you make Kook-Aid you use 2 
       cups of sugar. Compare the difference in 
       concentration.
   Label this one: Selective Permeability
  1. Write this statement: Selectively permeable 
  means only some molecules can pass 
  through the tiny spaces in a cell membrane.
  • Pour beaker contents into the sifter above the green 
   tray. Shake the sifter into the green tray.
  2. Write your observations
  3. Explain how the sifter is like the selectively 
  permeable membrane.
  • Pour green tray and sifter contents back into beaker 
   for the next group!!!!

    Watch this you tube video.
    • Her explanations are legit!
    1. Copy down what she says and does.
    • It’s okay to pause the video just don’t take too 
      long!
    Set it back to the beginning for the next group.
