First grade scientists have been observing solids, liquids and gases. The children mixed a "potion" in order to examine the properties of different liquids. They mixed water, food coloring and oil together to find that the oil and water did not mix! No matter how hard they shook the bottles, the liquids always separated from each other. In the next couple of weeks the students will be mixing different solids, such as sugar and salt, with water to see what happens.
