Kids On Science
--------------------------
The beguiling ideas about science quoted here were gleaned
from essays, exams, and classroom discussions. Most were
from 5th and 6th graders. They illustrate Mark Twain's
contention that the 'most interesting information comes from
children, for they tell all they know and then stop.'
*Question:What is one horsepower? *Answer:One horsepower is
the amount of energy it takes to drag a horse 500 feet in
one second.
*You can listen to thunder after lightening and tell how
close you came to getting hit. If you don't hear it, you got
hit, so never mind.
*Talc is found on rocks and on babies.
*The law of gravity says no fair jumping up without coming
back down.
*When they broke open molecules, they found they were only
stuffed with atoms. But when they broke open atoms, they
found them stuffed with explosions.
*When people run around and around in circles we say they
are crazy. When planets do it we say they are orbiting.
*Rainbows are just to look at, not to really understand.
*While the earth seems to be knowingly keeping its distance
from the sun, it is really only centrificating.
*Someday we may discover how to make magnets that can point
in any direction.
*South America has cold summers and hot winters, but somehow
they still manage.
*Most books now say our sun is a star. But it still knows
how to change back into a sun in the daytime.
*Water freezes at 32 degrees and boils at 212 degrees. There
are 180 degrees between freezing and boiling because there
are 180 degrees between north and south.
*A vibration is a motion that cannot make up its mind which
way it wants to go.
*There are 26 vitamins in all, but some of the letters are
yet to be discovered. Finding them all means living forever.
*There is a tremendous weight pushing down on the center of
the Earth because of so much population stomping around up
there these days.
*Lime is a green-tasting rock.
*Many dead animals in the past changed to fossils while
others preferred to be oil.
*Genetics explain why you look like your father and if you
don't why you should.
*Vacuums are nothings. We only mention them to let them know
we know they're there.
*Some oxygen molecules help fires burn while others help
make water, so sometimes it's brother against brother.
*Some people can tell what time it is by looking at the sun.
But I have never been able to make out the numbers.
*We say the cause of perfume disappearing is evaporation.
Evaporation gets blamed for a lot of things people forget to
put the top on.
*To most people solutions mean finding the answers. But to
chemists solutions are things that are still all mixed up.
*In looking at a drop of water under a microscope, we find
there are twice as many H's as O's.
*Clouds are high flying fogs.
*I am not sure how clouds get formed. But the clouds know
how to do it, and that is the important thing.
*Clouds just keep circling the earth around and around. And
around. There is not much else to do.
*Water vapor gets together in a cloud. When it is big enough
to be called a drop, it does.
*Humidity is the experience of looking for air and finding
water.
We keep track of the humidity in the air so we won't drown
when we breathe.
*Rain is often known as soft water, oppositely known as
hail.
*Rain is saved up in cloud banks.
*In some rocks you can find the fossil footprints of fishes.
*Cyanide is so poisonous that one drop of it on a dogs
tongue will kill the strongest man.
*A blizzard is when it snows sideways.
*A hurricane is a breeze of a bigly size.
*A monsoon is a French gentleman.
*Thunder is a rich source of loudness.
*Isotherms and isobars are even more important than their
names sound.
*It is so hot in some places that the people there have to
live in other places.
*The wind is like the air, only pushier.

林花谢了春红，
太匆匆，
无奈朝来寒雨晚来风。
胭脂泪，相留醉，
几时重。
自是人生长恨水长东。 |
