Color-Mixing Activities for World Science Day
November 10th marks World Science Day. This day celebrates science—in all of its forms. As part of the international science party, help your kids to learn, explore and experiment with a few kid-friendly color-mixing science activities. These are easily adaptable for children of different ages. Keep in mind, even though your child should be the one doing the exploration, you should provide supervision at all times.
Explore color mixing, absorption and much, much more with this experiment that the kids will say is totally “cool.” Fill two or more glass jars halfway up with water. Drip a few drops of food coloring in each. Use the primary colors (red, blue and yellow) to start. Only add one color to each jar. Put an empty jar in between the colorful water jars. Roll cheap paper towels or toilet paper into wand shapes. Put one end the colorful water and the other in the empty jar. Repeat for the colored water jar on the other side of the empty one. Watch as the water “walks” up and into the empty jar (and the colors will mix too!).
Make three batches of ice cubes: One yellow, one red and one blue. Simply drip a drop or two of food coloring into an ice cube tray, add water and freeze. When the cubes are ready, take them out and put them on plain white paper. Your child can push the ice around the paper, watching the colors mix.
Colors don’t mix the same in every liquid. Have your child predict which liquids will let the colors mix. Then try a few different types. Add food coloring to water, veggie oil, milk, an almost clear juice (such as white grape) or seltzer. Your child can mix the liquids and observe if the colors mix or not.
