This week is full of rainbow things – (see the rest of the parsha ideas for Noach here.)
We decided to try a science project in addition to rainbow cupcakes, coloring pages, a crayon, and more.
I found the idea as well as the science behind it here. It’s a project called a rainbow in a glass. The older boys and I tried this out.
First, we gathered our materials: 4 glasses, spoons, sugar, warm water, and food coloring.
Then, we put one tablespoon of sugar into one glass, three into the next, and five into the third. We added a small scoop of gel food coloring to each cup: red, blue, and yellow. Then everyone stirred.
When it was about as well mixed as we could get it, we added a tablespoon of water and mixed,
then mixed in a total of 3 tablespoons of warm water into each. It’s important that you keep these sugar solutions different concentrations so the layers float – for a while, at least!
Then we carefully poured the blue/heaviest solution into the bottom of the glass. Next came the yellow, pouring over a spoon to try and get it to “lay” on the blue layer. Last came the red.
We should have three layers of colored water, maybe a little mixing in between for our rainbow goodness, right?
Here’s what it should have looked like:
Here’s what ours looked like: twice! (I did it once with the kids and once by myself. Same result.) Pouring is messy!
BUT…we did have a rainbow as we dumped it down the drain…
We think that either the dye was too dark, the water was too warm, or maybe poured in too hard? (I poured over a spoon down the side and then from a dropper to a spoon, but no luck.)
In any case, we had some fun with the parsha. More to come!
Are you doing anything with parshat Noach? (Link has more ideas, but I’d love to hear yours!)
