Tell the children that you are going to put some food coloring drops
into the glass of water. Discuss what they think will happen.
Drop several drops of the coloring into the glass (have the
children count the drops as you add them). Let the children watch
what happens to the water. Talk about what is happening. Add
several more drops, what is happening now? Repeat several more
times, talking about the change each time.
Have several glasses of clear water. Put 2 drops of coloring into
the first glass. Put 4 drops into second glass and 6 drops into
the third glass. Each time ask the children to predict what will
happen and compare results. Note the differences and similarities
between the glasses.
