Today's Daily Question Came Directly Off of Study Island
We then did a couple different demonstrations. The first was just to simply see the movement of water from high to low concentration.
We let those sit for a while as we took the next slide of notes
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.

| 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! |
