Then take a bottle of food coloring, hold it up, and say: "Have you ever wondered what happens when you mix things together? Would salt water and plain water react the same way if I add this food coloring? Let's find out!" Stimulating Thinking (Engage Questions): "What do you think will happen when I add food coloring to water? Will it spread out the same way in plain water and salt water?" "What might I notice if I look very carefully?" "Can mixing these things together make something totally new?" "How could we use our observations to figure out what's changing?" Encourage students to ask themselves: Why does the food coloring spread the way it does? What am I seeing that could be evidence of a change? Is this just mixing, or did we make something new? Example Student Wondering: "What can I find out about what happens when different things are mixed together
