Science: Color Bottles



From Kindergartners At Work II - The Super 6 Continue - by Trish Saccomano & Kathy Bringhurst

Science experiment:  Save those empty plastic water bottles, you'll need 3, and use them for this effective demonstration of primary color mixing resulting in secondary colors.  Use food coloring to color the water in one bottle yellow, one red, and one blue. Students place the bottles of colored water on a sunny windowsill. They move the bottles in front of each other to create secondary colors (green, purple and orange). Students then illustrate and write about their findings in Discovery Journals.  These journals can be used throughout the year for students to draw/write about their discoveries for that all important Literacy connection.
