Water is a universal solvent because it ...
can be found anywhere.
floats when frozen.
freezes when it gets cold.
dissolves most substances.
What happens when water turns into ice?
The water becomes a solid.
The water makes a crystal structure.
The water expands when it freezes.
All of the above.
Ice can float on the surface of water because ...
it is sturdy but light.
it is due to buoyancy.
it contains a natural mineral in its substance.
there is a special coating on the ice.
Why are water droplets a "tear drop" shape?
They're not, silly!
By how they're released from the cloud
Water in the middle pulls the surface "in" (i.e. gravity)
The force of smacking on a surface
Water bugs can walk on water because of ________________.
surfing
surface tension
natural ability
an internal stabilizer
Water particles ___________________.
are attracted to each other.
repel against each other.
stick to water striders.
cannot be broken down.
Water striders can walk across the surface of calm water. Their feet push the surface of the water down slightly, but they do not break the surface. Why?
The insects are light enough so they do not break the hydrogen bonds holding the water molecules together.
The insect’s feet are non-polar, so they are repelled by the polar water molecules and are pushed away from the water’s surface.
The insects actually use their wings to hover slightly above the water’s surface and they only skim it with their feet.
The insects are small enough to see the individual water molecules, so they are able to step carefully from one molecule to the next.
You can see surface tension when you slowly ________ a glass of water.
under-fill
overfill
pour out water from
wash
The water will make a _______ above the top of the glass but won’t spill out.
splash
hole
wavy pattern
dome / curve
In the video, the water surface stretches to bounce the milk drop back up into the air.
True
False
The water behaves as if it is covered by ....
a magnetic force
a sheet of ice crystals
a thin, elastic film on the surface
a glass mirror
In a video experiment, the chili flakes are able to _____________ the water until the soap in is placed in the water to __________
scatter around on; make the chili flakes sink
sink into; cause the chili flakes to re-surface on the water
float on; strengthen the attraction between the chili flakes
float on; break the surface tension in its surrounding area
In another video experiment, the paper clip is able to float on water because ...
the weight of the paper clip is light enough.
the water molecules bind tightly together to support the weight of the paper clip.
the pull of gravity does not exist in such a small surface area.
this is a magical trick that requires a lot of practice.
In that experiment, the paper clip is not truly floating, but is held up by ...
the push and pull force of gravity.
surface tension.
water density.
a protective layer of invisible crystals.
Would you try these water tension experiments at home?
Yes
No
