Water discoveries

On Friday, scientists were at work in the classroom.

With colored water, salt, oil, and soap,
many interesting concoctions were made in test tubes. At one point in the morning, when two colors were added and stayed separated, a child declared "I made tie dye" And thus the "tie dye" effect was born. After that any mixture in which the colors did not mix until shaken was called "tie dye"

The children also created a "water shed" using gravel covered with a mixture of clay and sand.

They created rivers on the hill that flowed as the rain fell.
