Color changing milk activity with bowl and other supplies

Color Changing Milk

Color Changing Milk

Topic/Theme: Science


  • Bowls or shallow plates
  • Milk
  • Food coloring (several different colors work best)
  • Q-tips
  • Dish soap

Video Discussion:

Tell students they will be watching the video ‘Science Careers’. Explain that the video presents role models talking about why a career in science is very desirable and fulfilling.

After watching the video together, invite students to share specific things they learned about the different science careers featured in the video and to reflect upon their observations (e.g., ‘I liked knowing that a career in science can lead to many other career opportunities.’).

Activity Instructions:

  1. Pour the milk to cover the bottom of the bowl or plate.
  2. Add several drops of varied food coloring into the milk, a bit distant from each other.
  3. Put a bit of dish soap onto the q-tip.
  4. Dip the q-tip into the food coloring and hold it in place for 10-15 seconds as the milk separates and the patterns emerge.
