pH Cabbage indicator tutorial and labs
~:: STEM Mom ::~
Although pH paper won’t break the bank, it is easy to make a pH indicator solution (or paper) from supplies you can get at your local grocery. What you need:
- red cabbage
- filter paper or coffee filters
- boiling water
- pot
- strainer
I’ve taken a lot of photos, because red cabbage is absolutely beautiful! But really, making the solution as easy as boiling a cabbage and using the water as the indicator!
ABOUT DARCI: STEMmom.org’s mission is to provide a community where public, private, and homeschooling teachers can connect and share inquiry science, technology, engineering, and math (STEM) activities. Darci’s passion is helping kids of all ages learn about the process of science, rather than the facts. Because she homeschools her young children, teaches high school, and provides professional development for teachers, articles in the same week may vary from the science behind glow-in-the-dark oobleck (geared to preschoolers, but fun for any age)—to sharing a high-school lab where students must remove the “contaminates” from a pseudo marine oil spill.
