What happens when oil and water mix? What happens when you add color and paper?
Marble Painting
My eight year old loves to do science experiments and loves art. In fact, I haven't met a child who does not like to experiment. We decided to combine a scientific inquiry with an artistic medium. My daughter knew that oil and water do not mix but she was eager to discover what would happen if we added color.
Materials: Heavy paper (we used watercolor paper), food coloring or liquid watercolors, vegetable oil, a large plate and 5 or more small cups, syringe or spoon.
Step 1: First we gathered all of our supplies and then put an inch of water in our deep plate.
Step 2: Then we gathered five cups and poured a tablespoon or more of oil into each one.
Step 3: Then we dropped food coloring into each cup (about 3-5 drops) and stirred it up so that there will lots of little droplets of color.
Step 4: We then took a syringe and filled it full of oil/food coloring from one cup at a time and squirted it into the large plate with water. We could try a few different colors and experimented with mixing the oil in more or less depending on how many dots we wanted.
Step 5: We lay a small piece of the paper onto the water and let it float, absorbing the water and oil.
Step 6: We lay the paper on a paper towel to dry and watched as the colors appeared. We repeated the process sometimes dumping the water out and getting clean water to experiment with different colors.
This was a fun process and allowed my daughters and I to question and experiment together, something we all enjoy. We loved watching the colors appear and naming our creations. This pink one is called bubblegum.
