Project Description

Kindergarten Science and PH Indicators


This experiment will get the kids exploring!

How cool is this PH colour changing tutu? You can easily make this at home and I’ll link the tutu printable below. I also mentioned in the clip the beautiful tutu of I love plum and I’ll link that below too.

These are the 3 ingredients you will need to mix with salt to make the three different colours.

A few days ago, I was asked to join in collaboration with @plumnyc to help raise money, through sales of their beautiful tutus, to support @nokidhungry. This service provides food for kids in the USA.

I aimed to provide a cool tutu meets science activity to match @plumnyc beautiful philosophy and tutu. And I’ve got to say it not only turned out beautifully but it was also a huge hit. I’ve been told it was the best part of the kids day ❤️. And yes, it made me feel so good ????????. We’re now doing it again tomorrow.

I have a full tutorial out on YouTube, see above.

If you want to get your exploration on, all you need to do is make 3 different mixtures of salt and with 1. bicarb, 2. citric acid and 3. washing powder. Sprinkle this on glue and drop red cabbage juice into it.

Key Vocabulary To Use While Doing This Experiment.

  • Mixtures
  • PH
  • Reaction
  • Indicator

The Science:

The PH scale shows how acidy or basic a substance is. It works by transferring or receiving ions into the mixture when an indicator is added. Essentially the indicator gives a + ion or – ion to the mixture and this reaction changes the colour. That pretty cool because now we can see that the ion concentration has changed.

Why do we need to know this:

I’ll give you a story to best describe the importance of PH. Let’s say you jump in your rocket and go to a new planet and start exploring. While marvelling at this beautiful unfamiliar world you find a new type of rock. You want to know it is.

A first step in testing could be to crush it up and put an indicator on to it. WOW, now it turns pink. Oh no, you realise you need to put your gloves on as it’s an acid and could burn your hands. Great job, you just learn your first thing about this mysterious rock and have protected yourself. Now you can break the rock down further and do some other types of experiments to single out what it is.
