A Simple Science Project: DIY pH Indicator
To kick off this simple science experiment, let's flashback to our chemistry classes where we learned about acids and bases. High on the pH scale, you'll find common household items like baking soda and bleach, these are known as bases. On the contrary, sour elements like lemon and vinegar are found on the lower side of the pH scale, classifying them as acids. The middle of the pH scale, around a neutral pH of 7, is where pure water resides. As an easy science project, think about it as trying to organize a grandiose, colorful party where the high pH bases will be the cool blues and greens, while the acidic, low pH materials plan to strut in with their vibrant red, orange and yellow outfits!
Creating A Homemade pH Indicator
Creating a homemade pH indicator will allow you to identify the acid-base balance in a substance in the most spectacular way - through color! Imagine adding a drop of your homemade indicator into a solution and watching it transform into a full spectrum of colors. Hence, the first candidate for our DIY pH indicator is the red cabbage. Red cabbage is a natural pH indicator due to the presence of a substance named 'Anthocyanin.' This compound reacts with acids and bases resulting in a cool color change.
The Actual Making of a pH Test
Now, let's move to the actual making of a pH test, an exciting part of your home-based science project! All you need is a red cabbage, a knife, blender, strainer, hot water, clear cups, and substances to test their pH. Cut the cabbage into chunks, blend with hot water, then strain the mixture.

Ingredients:
- 1/2 head of red cabbage
- Water
- Various household substances (vinegar, baking soda, soap, lemon juice, etc.)
- A pot for boiling
- Strainer
- Clear glasses or test tubes
Instructions:
Step 1: Preparing the pH Indicator
- Chop the red cabbage into small pieces until you have about 2 cups worth.
- Place the chopped cabbage in a pot and add enough water to completely cover the cabbage.
- Heat the pot until the water is boiling, let it boil for about 10 minutes.
- Remove the pot from the heat and let the water cool.
- Using a strainer, strain out the cabbage pieces, collecting the 'juice' in a container. This purple liquid is your pH indicator!
Step 2: Testing the pH Indicator
- Divide the cabbage juice among several clear containers or test tubes.
- Add a different substance to each container: a squirt of lemon juice in one, a spoonful of baking soda in another, some soap, and so on. Stir well.
- Observe the color changes. Acids will turn the cabbage juice pink or red, while bases will turn it green or yellow!
Discuss:
Once your child has observed these fascinating color changes, explain to them why they happened. The red cabbage contains a pigment molecule called flavin which changes color under different pH. Make sure you reinforce that this is how scientists measure the acidity or basicity of unknown liquids!
Red Cabbage PH Indicator STEM Experiment
Objective:
This experiment aims to demonstrate the color-changing phenomenon which results from boiling red cabbage leaves. This change in color is due to a pigment in red cabbage called anthocyanin which serves as a pH indicator.
Materials Required:
- Red cabbage leaves
- Water
- Lemon juice (acidic substance)
- Baking soda (basic substance)
- Stove and pot
- Three glass beakers or clear containers
- Strainer
Procedure:
Step 1: Chop up the red cabbage leaves into small pieces.
Step 2: Place the chopped cabbage into the pot and fill it with enough water to cover the cabbage.
Step 3: Heat the pot on the stove until the water begins to boil, then lower the heat and let it simmer for 30 minutes.
Step 4: After 30 minutes, remove the pot from heat and let it cool. The water should now be a deep purple color.
Step 5: Strain the mixture into a beaker or clear container, separating the cabbage pieces from the liquid. This liquid is your pH indicator!
Step 6: Pour some of the cabbage juice into two additional beakers.
Step 7: Add a small amount of lemon juice to one of these beakers. Expect to see the cabbage juice change color.
Step 8: Add a small amount of baking soda to the other beaker. Again, observe the color change.
Explanation:
The red cabbage contains a pigment called anthocyanin that changes color when it comes in contact with an acid or a base. When the acidic lemon juice was added, it turned the indicator a pinkish-red color. When the baking soda, a base, was added, the indicator turned a greenish-yellow color. This means the color of the cabbage juice depends on the pH of its environment.
