What a great day. Hey, what's it like outside where you are right
now? Is it hot old
rainy about whatever kind of day it is? You see the day like it
sometime before, maybe even yesterday.
When we look at the world around us, there are things that seem to happen
over and over, like changes that happen in different
seasons. Right now it's summer. Here I am,
and that usually means it's going to be pretty warm outside
and, uh, who it is.
But after the summer comes fall and things will cool down
quite a bit, then fall will turn into winter,
depending upon where you live. It could get very cold in the
winter, but eventually winter warms up and becomes
spring. And that's when everything it's nice and
green again and flowers bloom. And from there
you had back into summer, where the whole thing starts
all over again and keeps on happening year after
year. When things keep repeating like this in nature,
we call it a day pattern. Patterns can help us to
know what to expect and even when to
expect it. There are lots of changing
patterns that happen. All the time in nature. We've gotten so used to
some of them we don't even think about it.
Another pattern we see happen in nature is how will the moon looks.
The more looks like it changes a little each day, and sometimes
we see a phone like this. But then slowly
over a period of days, part of it becomes dark and it looks
like this. Then more days go by and it gets dark,
soap willing sing About half of the moon lit up and
in a few more days we see just a sliver left until
finally we don't see anything at all. Then guess
what happens. We start to see a solider of the moon
again. Then, as the days go by, we get to see Maur and
Maura until finally the part we see is all lit
up again. Then the whole thing starts all over its
ah pattern that we can see happening with the moon.
Unfortunately, it takes some time to see changing
patterns like with the Seasons or the moon.
But there are some patterns that you can see every day.
One of the easiest patterns be to seize the pattern of nighttime
and daytime. Daytime is when we see the sun
lighting up everything all around us. Nighttime
is when we don't see the sun and it gets dark. It's a
pattern that repeats itself over and over everything.
Daytime and nighttime, daytime and
nighttime. Hey, where you
going?
Ah, people like you and I spend our whole
lives learning about the world we live in to make it easier to learn.
It's important to get information about all the things we're
trying to learn about. Out. Information is anything. We try
to learn about something. One way to get information is by
using our senses. Art senses are the parts of our
bodies that tell us all about the world. I can use
my senses to get information about the snack I've made myself
here. Seeing is one of our senses. With my
eyes, I can see that the color of this apple
is red. Smell is
another sense. I
can smell the peanut butter I spread on this celery, and when I
bite into it, I can hear the crunch of the celery.
Mm. I can taste the peanut butter and the celery with
my tongue. Hearing and taste are
to warm our senses. Last since I've been using it
has been my sense of touch. It told me that the apple
feels smooth and the celery feels bumpy
and the peanut butter well that feel
sticky. Our senses give us information about many
different things, but there are lots of other ways to get information
to, huh?
And now it's the oldest scientist in the world,
you know, nowadays, you youngsters have it easy. Back in my
day, when we learned about science, there were no fancy shmancy
thermometers. We just touch everything with our
hands. And if it was too hot or too cold,
we didn't have any silly old magnifier to help us see little
stuff. We just held things up. Were you close to our
eyes? And if they were too tiny or too blurry,
that was just too bad.
We also didn't use your stupid duper rule lose its
scales to measure things. We just looked at them and
guest, and if they were do big or too small, that was
so. That's the way things were way couldn't see
that squished a big rat. That was good enough for us.
And if you don't like it. That's just too
bad. This has
been over scientist in the world.
Mmm. People use lots of different kinds of tools to help
make things or build things. But we also have tools. I can
help to get information and learn new things
way. Use a thermometer to figure out how hot
door cold something is, and numbers we read tell us the
temperature. Knowing the temperature could be important
information and thermometers don't always look the same, depending
on how we need to use them. Some
thermometers are made for telling us the temperature of liquids like water.
Other thermometers give us the temperature of the air.
There are thermometers made for ovens that can show us how hot it's getting,
and there are even thermometers that can tell us the temperature of your body.
But their mama tres aren't the only tools we used to get
information. This is called a magnifier.
Magnifier is a tool that makes things look bigger, so
they're easier for us to see and learn about a magnifier like this.
One is easy to use and you can hold it right in your
hand. But there are other kinds of tools that magnified things too.
Some things are so small, we need a special kind of magnifier called a
microscope to see them. He'd be very surprised that the kinds of
things you could see with a microscope that you can't see with your
eyes There are also magnifier that help us to see things
that are far away we can use. Magnifier is called
telescopes to see the moon, stars
and planets. But you should never use any magnifier
to look at the sun or bright lights that could
really hurt your eyes. Mmm.
Another tool that people used to get information is a
ruler. A ruler can help us to figure out how big something
is by looking at the numbers on it.
I've been taking care of this small plant here for a few
weeks and I'd like to find out if it's grown
taller. I look
at the numbers on my roar. I can see that this plant here is
about eight in just
tall. Now, that's definitely taller than when I first measured it.
So it must be growing, huh?
Waiting is rulers to tell us how tall something is,
how wind something is, and even how far it is
from one place to another. It's another tool
that gives us information.
Have you ever waited yourself on a scale before? Using a
scale is a great way to find out how heavy something is,
But scales are just used to weigh how heavy people are.
We use scales to weigh lots of different things.
Scales, conway, fruits and vegetables, heavy
packages, just about anything and a scale called
a balance could be used to compare how heavy things are.
Besides thermometers, rulers Magnifier, tze
and scales, there are lots and lots of tools that help get
information about the world all around us. New information not
only helps us to learn new things, it tells us about
what we need to do to take care of ourselves and make the
world a better place. What kinds of tools do you use to
learn about the world?
There's so much to learn about the world, and there's more information out there than
anyone can remember. That's why when you're learning about science, it's
important to work together and share information with each
other. When people work together and share things we can
make and do all kinds of things
waken go rockets and space
stations walking together. Doctors can help
people, and we can find out about when a bad storm is
coming so we can stay safe. You see, different
people are good at different things. The people that wrote each one of
these books were all good at something and did it to
share information with other people. So what are you
interested in? Dinosaurs, Stars and
planets? Oceans? My guess is there are other people
out there that are interested in the same thing. I bet they're willing
to share what they know with you.
Learn about your world
way, see the world around us, changing all the time.
Often we see the same kinds of changes as time passes,
like when the seasons change from spring to summer
to fall to winter. Then it starts
all over again. With spring. When things repeat like that, it's
called a pattern. We also see patterns in nature
as the moon changes. As the sun rises and
sets to learn about our world, it's important to
gather information. We can do this by using our
senses. We see
here smell, taste
and touch things. Sometimes We use special tools to
gather information. Thermometers tell us the temperature of
things so we know how hot or cold they are.
Magnifier Sze make it easier to see things
Rulers help us to measure things and scales
help us tow way things. It's important to share the
information we learn with others. What kinds of things have you
learned about that you could share?
Scientists use all kinds of different tools to learn about the
world we live in, and they're even tools that help us learn about things
beyond our world. A telescope like this one can help you
see the moon stars and even planets
way out in space. It's made to help us see things that are
far away. Using our senses and
scientific tools helps us learn all about our world and
even worlds beyond the right tools. We can all be
scientists, you and me
