OOBLECK Anyone?

The children, again, were experimenting with matter, the three stages of, and how they can change from one stage to another.  So they made OOBLECK.  Fun times.  We started with a solid (starch) and a liquid (water and food coloring).  However, as you read this gas is occurring (evaporation).  This ongoing observation will be happened over the next week as the students see it go from a liquid to a solid to a liquid to a gas, over and over.

    

Day 1

solid + liquid = liquid on top, solid on bottom

    

Day 2

solid + touch and movement = gooey liquid…over time what will happen?
