Cell Membrane Structure and Kidney Demonstration

 Today's Daily Questions Came Directly off of Study Island.

We only did number 9 on this screen.

 Then we continued with the notes about the cell membrane

Before we moved to the next slide I had you take your "Kidney Cell" that was filled with simulated blood (it contains all the chemical components of our blood but is NOT actually animal blood) and place it in a cup of water.

Kidney Cells in a semi-permeable membrane

By the time you were finished with this slide most of your cups looked something like this.
This was showing you how cell membranes are SEMI permeable.  The membrane allowed urea and salts through
but they did not allow larger molecules such as red blood cells through (otherwise the water would have been red)
What you just made was simulated urine!
