In a few days the Jews all over the world will be celebrating Passover, one of the most important holidays of Jewish faith. While we are not religious, we do celebrate Passover as a “heritage holiday” for our family. In honor of Passover, I am joining other multi-cultural kid bloggers to share Passover ideas and activities for kids. My contribution will be the experiment to turn water into blood.

Plagues of Egypt

Plagues of Egypt are the major part of Exodus story and my daughter found them both very scary and very fascinating. The “water to blood” is the first plague followed by frogs, lice, flies, death of livestock, boils, thunder and hail, locusts, darkness, and, finally, the most terrible plague of all, death of firstborns. When we read about plagues and watched “Prince of Egypt” movie, I kept wondering what kind of twisted pride kept the pharaoh from giving in right there when all waters of Egypt turned into blood and how often even today pride of country leaders or heads of big corporations leads their subjects to ruin.

Water into Blood Experiment

Can you turn water into blood? No, but you can surprise your children with this chemistry experiment. Original source of it is here:
Water-into-Blood-start You will need one “real chemical” for this experiment – a PH indicator phenolphthalein. We got ours at Amazon. The second component needed is sodium carbonate, also known as “soda ash”. You can easily make it by heating baking soda (I heated ours for about an hour at 400 F). Now sprinkle sodium carbonate, which is a strong base, in one glass and fill the other glass half with water. Add 10 drops of phenolphthalein to it. Pour your water into a glass with sodium carbonate, and here you have it – water into blood. You can also call it water into wine if you want to make it into more of a New Testament project.
Water-into-Blood-endA few notes about this experiment:
  • If you just want to surprise your children with how two clear liquids will make color, you can dissolve soda ash in water, but the color will be a lot more “magenta”.
  • Perhaps more phenolphthalein will result in a richer color. We haven’t experimented much with it yet, since I am sick at the moment. I might report on it later.
  • It goes without saying that nobody should try to taste this experiment, but remember that I “told you so”. Don’t leave your children unsupervised when real chemicals are in play.

Have you ever bought real chemicals for your homeschool or after school? It was the first time ever for us so far.

I sat for a while wondering which board to put this under. I ended up putting it under Exodus, but it was something I thought about for a while.

We've worked with a few "real chemicals" but not many yet.

We've done this by just putting a little Kool-Aid powder in the bottom of the glass, so when you pour the water in it turns red :)

We've worked with more serious "non-kitchen" chemicals on occasion - usually as part of a science kit. I'm not in love with things that can burn skin or blow-up the house, so we usually stick with what I know will be safe to handle.

This is SO cool, we just watched "Exodus: Gods and Kings" last night and so the story of Moses is on my mind, what a great idea!

Very cool experiment. I haven't bought chemicals, but my kids would love an experiment like this.
