What you need to make the rainbow walking water science project:
6 mason jars
food coloring
paper towels
timer
paper and pencils
Fill three jars full of water. Add red food coloring t o one, blue to another, and yellow to another. Go over the color wheel before starting. Show the kids how mixing colors will create different colors. However, don’t tell them how to make the rainbow! Let the children discuss how they will make a rainbow from just three colors. It will take them a little bit to determine the right combination.
If the children are stuck you can help them out by reminding them what colors are together in a rainbow. Put an empty jar between red and yellow, yellow and blue, and blue and red. Have the children roll the paper towels in to tube-like pieces and put one end in a full jar and the other end in an empty jar.
The paper towels will start soaking up the water right away, but it will take about 48 hours before the process is finished. Set a timer to find out exactly how long it takes to start mixing colors. children can write down the time they guess it will take and then the actual time it took.
2. Design two open-ended questions that you would ask the children to extend their learning . For example;
How long do you think it will take for the colors to start showing up in the paper towels?
What is your favorite color?
What do you think will happen if we add more food coloring or more water?
What two colors make _______?
Have fun with it!
