One of my favorite things is science. I have found that even the simplest science experiments with my kids leads to unexpected discovery.
The funny thing about kids and science is that I THINK I am teaching one thing.
And then they go off on a tangent of curiosity and we end up somewhere completely unplanned.
Which is the point of experimentation!
Over the next few weeks, I am going to be writing about a series of science experiments from Workman Publishing. Each is a simple experiment for kids that uses household items.
Water Surface Tension Experiment
- Bowl of water
- Black pepper
- Bar of soap
1. Sprinkle black pepper on the water.
2. Place finger in the water and watch what happens.
3. Is your finger covered with pepper?
4. Clean finger!
5. Rub clean finger with soap.
6. Place finger back in water to see what happens.
7. Does the pepper FLEE from your finger?
The soap didn’t change the pepper. The soap changed the water’s surface tension. This is why soap works! Soap causes the water molecules to relax and not hold on to each other so tightly. That is why soap cleans you and can get stains out of your clothes.
There is a printable version of this Surface Tension Experiment for Kids from Pop Bottle Science by Lynn Brunelle here.
