Colourful Science

We have been studying colour in Lower Elementary science all week. Today, we mixed watercolours to create Ph Scale reader card. Afterward, we tested the acidity/alkalinity of different liquids and matched them to the scales. Those that were more acid tended toward the red end of the spectrum and those that were more alkaline tended toward purple. The children were sent home with an assignment to measure four different liquids at home and bring their findings back in to share with the group.
