Twinkle, twinkle, little star,
Look how clean my two hands are!
Wash the back and then the front,
Between the fingers rub-a-dub.
Twinkle, twinkle, little star,
Look how clean my two hands are!

Today we had a CLEAN HANDS presentation… that was also a SCIENCE EXPERIMENT!

First of all we got to sprinkle red sparkles all over our hands. The sparkles were simulated GERMS (but actually, they were very pretty germs!) Then we began the experiment. We tested three ways of cleaning our hands.

The first way was by just wiping our hands with a paper towel. Oh dear! That didn’t get rid of very many germs at all!

The second way was to wash our hands in cold water and then dry with a paper towel. That was a little bit better, but still not very good.

The last part of the experiment was to wash our hands with SOAP and WARM WATER and then dry with a paper towel. Yeah! That was the best way to get rid of those sparkly germs!

We also learned that you need to be sure to wash for as long as it takes to sing “Twinkle, Twinkle little star” or “Happy Birthday”. Then you need to turn off the tap with your paper towel (otherwise those germs you left on the tap will go right back on your hands!) Mrs. Boekhout was a little concerned about having the water run for so long. (After all, we aren’t supposed to let the water run while we brush our teeth, right?) One idea is to not run the water too hard. Another idea is to just wet your hands and turn off the tap. Wash while you sing and then turn the tap on again and give another little wash before you rinse. Then use the paper towel to turn off the tap,

It might sound complicated, but we want to GET RID OF GERMS but still NOT WASTE WATER!
