Surface Tension

We have been studying water in our class. Here are some things we have learned:

"Salt water sort of cleaned the penny," said Colton.

Michael said, "The drops of water bounce on surfaces of water."

"When I was observing the penny, when I dropped the salt water on top of it the salt water made the water drops look like it had bubbles in it, " Kennedy explained.

"Soap water made the water dome pop," Kathy described.

Haden said," When you put water on the penny, the water stays up and it turns into an oval."

"The class studied that you can get 25 drops of water on one penny," replied Dylan.

"When I put salt water on the penny, you can see the salt," explained Chidy.

Hailey E. stated, "When you put 15 drops of water and as many drops of soap water and salt water, whatever number you got to it spilled."

"I learned that if you put salt water on your penny it will make the penny steady," explained Madison.

Blake said,"When you put the soapy water on the penny, it made all the water fall off the penny."

"I learned if you put on soapy water on top of 15 drops and too much of soapy water, it will just spill," stated Camryn.

Diamond explained, "The soapy water cleaned the penny."

"When you put the 15 drops and you added the soapy water, it ran over and when you put the salt water on the penny you could sort of see the salt," stated Connor.

Kierra says, "You put soapy water on the penny it just disappeared."


Surface tension is the ability of water to stick together.

We watched a video showing water drops in slow motion. Here is the link to the video: http://www.flixxy.com/water-drop.htm
