The children were testing different temperature water with baby oil and food coloring. They mixed different colors of food coloring with baby oil. They dropped the food coloring in cold,warm, and hot water. The children concluded that the food coloring and oil will take a longer time to mix and cold water. They also observe that it was easily to mix when the water got hotter. They also made a conclusion that the oil was thicker than water so that why it separates from each other.
