Polarity
What is polarity?
It is when a bond of different atoms have both a positive charge on one side, and a negative charge on the other side.
What are the ingredients for this experiment?
Dish, Milk, Soap, Qtip, and Food Coloring
What are the ingredients for this art project?
Water, big bowl, paint, paper, paper towel/towel.
What macroinvertebrates takes advantage of surface tension and skid/whirl across the water?
A water strider and a whirligig beetle.
What is water’s chemical formula?
H2O
What do opposites do?
Attract
What is the soap doing in this experiment?
Is is a surfactant in this experiment which breaks the surface tension in the milk.
What paper should you use in this experiment?
You should use a piece of paper that can absorb things very well, however, any paper will do.
What does the water strider have on its legs in order to not break surface tension?
Hair
What is water made up of?
2 Hydrogen atoms and 1 Oxygen atom.
Yes
What is milk made out of?
Fat and Water
What happens to the paint as it goes on the water?
The paint is held by surface tension.
How does the water strider detect a small insect to eat?
By feeling the vibrations the small insect makes when it lands on the surface of the water.
What is Electroegativity?
The tendency for an atom to take on additional electrons.
Where are the water molecules cohesive?
At the surface of water.
What happens in this experiment?
The soap breaks surface tension allowing the water to move about which then bumps into the fat which then all bumps into the food coloring, creating a colorful effect.
What country is this art form from?
Japan
Where do water striders spend their time at?
Slow-moving or still areas of water.
What is a compound?
Two or more elements that are chemically combined.
What does an oxygen atom from one water molecule attract to?
A Hydrogen atom
What happens when you take the Qtip with soap on it out of the milk?
The effect keeps happening.
Is clean up of this art form easy?
Yes
Is a water strider a spider?
No, spiders have 8 legs, but a water strider has 6 legs.
What are molecules?
It is the smallest amount of a bond to still have the same properties of that bond.
