🚀 Introduction to the Solar System
Miss Freeman introduces a science lesson aimed at Grade 7 students, focusing on the exploration of the solar system. The lesson begins with a recap of the previous session where a homemade barometer was made. The objectives for the current session are to define the term 'solar system' and identify its members. The solar system is described as a collection of eight planets that orbit the sun in a circular path, with Pluto no longer classified as a planet. The members of the solar system include the sun, planets, asteroids, comets, meteors, meteorites, and satellites. The sun is highlighted as the center of the solar system and a medium-sized star. The planets are listed and two mnemonic devices are provided to help remember their order: 'My Very Educated Mother Just Served Us Noodles' and 'Merry Very Early Make Jean Shake Up Nelly'.
🌌 Deep Dive into Solar System Components
This paragraph delves into the details of the various components of the solar system. Asteroids are introduced as small, rocky bodies that orbit the sun and appear as points of light through a telescope, similar to stars. Comets are described as small icy objects that also orbit the sun, with an accompanying image for reference. Meteors, or 'shooting stars,' are explained as streaks of light caused by small pieces of matter burning up in Earth's atmosphere. The distinction between meteoroids, meteors, and meteorites is clarified, with meteoroids being the objects in space, meteors being the flares caused by burning up in the atmosphere, and meteorites being the remnants that strike Earth's surface. Meteorites are valuable to scientists as they provide insights into the solar system. Satellites, both natural and artificial, are the next topic, with natural satellites like the moon orbiting Earth, and artificial satellites such as the Hubble Space Telescope and the International Space Station serving practical applications like weather forecasting and telecommunications. The lesson concludes with an invitation to join another session to further explore the planets of the solar system.

hello boys and girls and welcome to
another lesson of science and daily life
in the grade 7 classroom
my name is miss freeman and i'm here to
take you on a journey in exploring the
solar system
now before we do that boys and girls can
you recall what we did in our last
session
yes
we made a homemade barometer
now today boys and girls our objectives
are one
to define what is meant by the term
solar system
and two to identify the members that are
found in the solar system
now
what is
a solar system
the solar system is made up of a
collection of eight planets that
revolves around the sun in a circular
path
however
it used to be nine planets but now pluto
is considered to no longer be a planet
so boys and girls you heard correct
there are eight planets
and a solar system is a collection of
those eight planets that revolves around
the sun in a circular fat
who are the members of the solar system
we have boys and girls one
the sun
two
the planets
three asteroids
four
comets
five meteors
six meteorites
seven satellites
let us start with the sun
the sun is our very own star
the sun is in the center of our solar
system
the word solar means of the sun
our sun is a medium-sized star
here boys and girls is an image of our
sun
let us move right on into the planets
boys and girls can you list or can you
name the planets found in the solar
system
the planets found in the solar system
are 1
mercury
2
venus
3
earth
4
mars
5
jupiter
6 saturn
7 uranus
8
neptune
an easier way in which we can remember
the planet is by using an acronym or a
rhyme
here today students i have for you two
acronyms or rhymes used to remember our
planet
or the planets found in the solar system
first let us start with number one
my
very
educated mother
just
served us
noodles
as you can see what we did there boys
and girls is that we use the first
letter of each word to represent the
first letter of each planet
again
my
very
educated mother
just
served us
noodles
it's simply saying mercury venus earth
mars jupiter saturn uranus and neptune
the second rhyme that we have is
merry
very early
make jean shake
up
nelly
again boys and girls
merry
very
early
make jean shake
up
nelly again it's representing
mercury venus earth
mars jupiter saturn uranus and neptune
now boys and girls let us dive into the
second member of the solar system
we have asteroids what are asteroids
asteroids are very small rocky bodies
that orbit the sun
asteroid means starlight and in a
telescope asteroids look like a point of
light just like stars
asteroids are irregular in shape no boys
and girls if you are to look at
the sky
through a telescope these asteroids will
also look like stars and they'll be
twinkling at us so we might be confused
and maybe say they are considered to be
stars as well but they are actually
asteroids there
now the next member that we have of the
solar system is called comets
comets are small icy objects that orbits
around the sun
here boys and girls you can see an image
of a comet
the next member that we have is called a
meteor
a meteor is a streak of light across the
sky
boys and girls
have you ever maybe in the night time
before you go to your bed you take a
look at the sky and you say you know
what you see a shooting star
now that shooting star is actually a
meteor
most of the time they're actually small
pieces of matter
burning up as they enter earth's
atmosphere from space
meteors are called meteoroids before
they reach the earth's atmosphere
the next member that we have is called
meteorites
although most meteors burn up in the
atmosphere
larger meteoroids may strike the earth's
surface to create a meteor right
so there are three terms we have there
we need to be careful of
meteor
major rights and major right
amid your boys and girls is when we have
that object in the earth's atmosphere
and it's burning up and it's causing
that flare
a meteor void it's when it's in the
into space and it's just moving along
a major right is when it lands
on earth's surface so those are the
three terms we need to be very careful
of
now mean your rights are valuable to
scientists because they provide clues
about our solar system
right here on earth we have different
meteorites up for exhibition that
tourists can go and have a look at
now another member of the solar system
is satellite what is a satellite
now a satellite is a body that orbits
around another body in space there are
two different types of satellites
you have one
natural
and two artificial
natural meaning it's fear as its own
and artificial simply saying it's
man-made
some examples of natural satellites are
the earth
and
the moon
the earth rotates around the sun
and the moon rotates around the earth
dear boys and girls we can see that a
satellite is a body that orbits around
another body in space
now boys and girls let us talk a little
bit about artificial satellites an
artificial satellite is a man-made
machine that is made and it's put into
the earth's atmosphere some examples of
man-made satellites are
one
the hubble space telescope and two the
international space station
artificial satellites have many
practical applications
they are used for forecasting weather
transmitting television and radio
signals
and also used for telecommunications
today we identified different members of
the solar system and we looked a little
bit more as to what each one means
do join me for another lesson as we
explore more on the different planets
found in the solar system
i am miss riemann and until next time
bye
