(CGUHS) While learning acids and bases, Ms. Ruby Armada's Chemistry class conducted a cool experiment called “The Rainbow Reaction Tube” where students observed the pH level change through color changes in an acid-base reaction tube. Students observed the beautiful color spectrum and had fun in this amazing, yet simple, experiment while learning the concept at the same time. Visit the Science Department at
