大致来讲，《科学读本》适合初中以上的学生阅读。英文程度较好的小学生，也可以从第一册开始。提供全书配套朗读文件免费下载，在学习科学知识的同时，更好地练习听读能力。
This series of Science Readers was published for the use of
teachers and students. It will be found useful, not only in those
schools in which Elementary Science is taken as a class subject,
but also for the purposes of an ordinary reader.
Of this series of Science Readers, Books I, II, and III are
adapted to pupils who are in their third and fourth years of school
work. Both the reading and the subject matter of Books IV, V, and
VI are suitable for Senior Grades.
It is hoped that the young readers who follow them through these
lessons will catch something of the enthusiasm and earnestness
which characterize them as they advance step by step from very
small beginnings to a real understanding of the elementary facts of
natural science.

Lesson 01
Water
Fred and his cousin Willie were two smart boys in the same
class at school. They were only little boys, but they were fond of
their school and their lessons.
They used to play at school in the evening with Fred’s little
sister Norah.
Their teacher was giving the class jolly lessons on some of
the common things around them. These were not at all like the other
lessons of the day. Teacher gave them to the class as a treat. The
boys soon began to look forward to them, as the best of all their
lessons.
Norah, too, liked to hear all about them from the boys. It was
great fun to sit around the fire in the evening, and chat over the
lessons of the day.
The first lesson was about water.
“What do you think, Norah?” said Fred one evening. “Teacher
began to talk to us about water, by showing us a saucer full of
sawdust.
“He piled up the sawdust in a heap in the saucer, and then
tried to do the same with some water in another saucer.”
“But, of course, he couldn’t do it,” said Willie,
“because you can’t make water stand up in a heap. It always
keeps a flat or level surface.”
“Yes; and, when it got to the top of the saucer, it ran away
over the sides, and on to the table,” added Fred. “We saw it flow
along the table, and fall down to the ground.”
“Why, of course,” said Norah, “water always flows down. We can
see it flow down, if we turn on the tap. It never flows up.”
“Teacher told us to think of the rain, too,” said Willie. “The
drops of rain always fall down—never up.”
“I can show you some drops of water.”said Fred.
“Look; I dip this brush in the water, and shake it. The water
will fall from the brush in little round drops.”
SUMMARY
We cannot pile up water in a heap; it always keeps a level
surface. Water breaks up into little drops, and flows about. Water
always flows down.
Lesson 02
Water—A Liquid
Norah’s mother called her away to mind the baby, before the
boys had told her all about their lesson. She came back as soon as
she could, and they began to chat again.
“I wonder whether Norah forgets what we learned about water,”
said Fred.
“No,” said Norah, “I don’t forget. I know that water flows,
and it always flows down. It keeps a flat surface, and it cannot
stand in a heap. It breaks up into round drops, but the drops will
run together again, and make a pool of water.”
“Quite right,” said Fred. “But now I’m going to puzzle you.
Can you tell me what shape water is?
“Teacher tried to puzzle us; didn’t he, Will? But he soon made
it clear. He showed us the saucer, and we saw that it was round.
Then he filled it with water, and of course it was easy to see that
the water in the saucer was round too.”
“But the water did not remain round,” said Willie, “for
teacher next poured it out of the saucer into a square tin
box.”
“I know.” said Norah, “it became square then, like the
box.”
“Right,” replied Fred, “and then we saw the water poured out
of the box into a tumbler; out of the tumbler into a jug; out of
the jug into a bottle. It took the shape of the new vessel each
time.
“Can you think of any other things, Norah, that would do as
water does?”
“I know some,” said Norah. “Milk and oil, vinegar and tea
would do the same.”
“Now, Norah,” said both boys at once, “you must try not to
forget the proper name for all these things. Teacher tells us to
call them liquids.
“Liquids flow about, break up into drops, take the shape of
the vessel which holds them, and cannot stand in a heap, but always
keep a level surface.”
SUMMARY
Water has no shape of its own. It always takes the shape of
the vessel which holds it. Water, milk, oil, and vinegar are
liquids.
