Surface Tension

Before I post my upcoming science experiment, it is important that we understand what surface tension is. Surface tension is like an elastic hold on a liquid. This is a simplified version of the definition, but it will be easier to see it demonstrated in the lab. So look out for that!!

Did you know that some bugs can walk and even run on water?!

This is from surface tension! The legs of the bug never really break the surface of the water because it is not heavy enough.

Try dripping some water on a penny and see how many drops you can get on top of it.

Surface tension allows the liquid to “stick” together and not just run right off of the penny.

How about this picture?

There are several animals that use surface tension to their advantage.

Where else can you see this occur in nature?
