Are you ready to wow your little ones with a fun, hands-on science experiment? I love using this Walking Water experiment to kick off every school year, but it can also be done at home.
You will need:
- 7 cups (4 halfway filled with water)
- Paper towels
- Food coloring: red, yellow and blue
- Line up your cups starting with one that is halfway filled with water, then one that is not, and continue that pattern.
- Fold your paper towel in half twice, first “hot dog” style, and then “hamburger style.”
- Add red food coloring to the first cup with water.
- Add yellow food coloring to the next cup with water.
- Add blue food coloring to the third cup with water.
- Add red food coloring to the last cup with water.
- Take one of your folded paper towels and place one end going into a cup with water and the other end into an empty cup. Place a paper towel between each cup in the row.
- Watch the water “walk” through the paper towels and combine in the empty cups! What do you see happening to the colors?
I love this activity as a first science project in my classroom because it is a great way for students to make predictions and observations. They are always in awe as the water begins to “walk” and mix into new colors.
My children at home (ages 2 and 4) love it too because it is a unique hands-on way for them to see primary colors mix and create secondary colors!
