Instead of using droppers to test the liquids, you can dip the indicator paper into the liquids and see the paper change colors.Īnd then they placed it on their observation sheet to compare with their previous resultsĬabbage juice acts as a pH indicator. Remove the paper from the liquid and let dry completely. Make sure to use an airtight container with a lid or your kitchen will stink in the morning! I placed 4 coffee filters in a container and added some Purple Potion to it. I decided to try to make my own indicator paper with some of the Purple Potion. (Even my middle school students used to struggle with this) The goal is to see if they can come up with some common characteristics of acids and bases. I think this was a bit over the top for a 6 yr old and he really was a bit lost at what to say. With my older son, I probed him on what the pink colored liquids had in common and what the blue colored liquids had in common. My older son made a pink concoction and said it looked like “antibiotics”! (Can you tell how sick we’ve been this past winter! ) I asked them what might happen if they start mixing some of the liquids together. Whoa! Look at all those colors! Why is it doing that? They added several drops of the purple potion to each well and observed the changes. I had them color in what the liquids looked like before we started.Įach superhero got a small cup of Purple Potion in a cup and a dropper. We used: water, milk, lemon juice, liquid soap, baking soda (dissolved in water), vinegar, apple juice, liquid soap and laundry detergent. I placed a variety of liquids from the kitchen into several wells of the tray. I placed an ice cube tray in front of each of the Superheroes. I ended up with about 4 cups of Purple Potion. Once cool, strain the mixture so that only the purple liquid is left. Remove from heat and let cool to room temperature so that it doesn’t burn your little ones. Make sure you have your exhaust fan on and your windows open. I added about 5 cups of water to mine.īring the cabbage/water mixture to a boil and then let simmer for about 15-20 minutes. Household liquids to test (water, vinegar, lemon juice, fruit juice, milk, baking soda/water, soda, laundry detergent, liquid soap, ammonia, etc…).Droppers (I save the ones we get from the pharmacist everytime one of my superheroes needs meds).Ice Cube Tray (or several small clear cups/jars).Red Cabbage (Why is it called red when it really looks purple?).The younger ones can enjoy the colorful reactions and the older ones can learn a bit about acids and bases and how pH indicators work. I’ve been wanting to do this simple kitchen science experiment with my kids for awhile now as I used to do this with my middle school students once upon a long time ago…This one is fantastic for superheroes of ALL ages.
