Coordenadas Geográficas
Aquí tenéis unos vídeos para saber cómo interpretar las coordenadas geográficas.
¡Espero que os animéis a localizar cualquier punto de la Tierra!
LAS REPRESENTACIONES DE LA TIERRA
El último día en clase estuvimos hablando de las representaciones de la Tierra y de las líneas imaginarias que nos ayudan a localizar exactamente cualquier punto de la Tierra.
En este mapamundi los paralelos (líneas horizontales) y los meridianos (líneas perpendiculares) se utilizan para marcar coordenadas geográficas.
hacia el este o hacia el oeste.
En este mapamundi los paralelos (líneas horizontales) y los meridianos (líneas perpendiculares) se utilizan para marcar coordenadas geográficas.
¿Cómo se interpretan las coordenadas
geográficas?
Utilizando dos distancias que se miden en grados.
·
Los paralelos indican la latitud (Norte-Sur):
Partiendo del ecuador (latitud 0º), se indica los grados que hay hacia el
norte o hacia el sur.
·
Los meridianos indican la longitud (Este-Oeste):
hacia el este o hacia el oeste.

UNIT 9: THE SOLAR SYSTEM
UNIT 9: THE SOLAR SYSTEM
Index:
1.1.- The Solar System
1.2.-The Sun
1.3.- Planets and Satellites
1.4.- Other celestial bodies in the Solar System
1.1.-
THE SOLAR SYSTEM
- The Solar System is made up of the Sun and
all the stars that orbit around it.
- The Earth is also part of the Solar System.
1.2.- THE SUN
- The Sun is
the closest star to the Earth.
- It is a huge mass of gasses made up of mainly
hydrogen that is shaped like a sphere.
- Because its surface is very hot, it gives us energy in
form
of light and
heat.
- When the Sun is in the sky, it is day. When we cannot see the Sun, it is
night.
1.3. PLANETS AND SATELLITES
- The planets of the Solar System do
not have their own light.
- They spin around their own axes and
orbit around the Sun.
- Almost all the planets have satellites.
Satellites are celestial bodies without their
own light that
orbit around a planet.
The eight planets of the Solar System
are classified into two groups:
|
Inner planets:
|
Outer planets:
|
|
- They are the closest to the Sun.
|
- They are the farthest from the Sun.
|
|
- They are smaller than the outer planets.
|
- They are much larger than the inner planets.
|
|
- They have a solid rock surface.
|
- They are made up of gasses like hydrogen and helium.
|
|
- Their density is high.
|
- Their density is low.
|
|
Inner planets are:
Mercury, Venus, Earth and Mars.
|
Outer planets are:
Jupiter, Saturn, Uranus and Neptune.
They are surrounded by many satellites.
|
1.4.- OTHER CELESTIAL BODIES IN THE
SOLAR SYSTEM
Our solar system is also made up of asteroids,
meteorites, comets and dwarf planets (planetas enanos).
·
Asteroids:
- They are fragments of rock or metal that move around the Sun.
- They are smaller than planets.
- Most of them are placed between Mars
and Jupiter what is called asteroid belt.
·
Meteorites:
- They are craters formed on the surface when asteroids hit (impactan
sobre) a planet or a satellite.
- Small meteorites that disintegrate in our atmosphere are called shooting
stars.
·
Comets:
- They are made of rock and ice.
- They come from two areas: The Oort Cloud (la
Nube de Oort) and The Kuiper Belt (el Cinturón de Kuiper).
- Solar energy evaporates the ice which forms the tail. This glowy path
(estela luminosa) can have millions of kilometers.
·
Dwarf planets:
- They are smaller than planets.
- They orbit the Sun further away than Neptune.
- Pluto is the most well known.
ACTIVITIES

SCIENCE-Unit 3: Invertebrates
Unit 3:
OTHER GROUPS OF INVERTEBRATES
INDEX:
1.
Common characteristics
2. Invertebrate animals with protective
covering.
Echinoderms
3. Invertebrates animals without
protective covering.
Worms
Sponges
Jellyfish,
anemones and corals
1.- COMMON
CHARACTERISTICS ____________________________
-
An
invertebrate is an animal without a backbone.
-
All Invertebrate
animals are oviparous: they are born from eggs.
-
Some
protect their bodies with shells or hard skin: molluscs, arthropods and
echinoderms.
-
Others have no protection: worms, sponges, jellyfish, anemones and
corals.
2.-
INVERTEBRATE ANIMALS WITH PROTECTIVE
COVERING._______________________________________________
ECHINODERMS
-
Echinoderms
are invertebrate animals that have bodies with a radial symmetry .
-
They live
in the sea, they are aquatic animals that move slowly along the sea
floor.
-
Some have
their body covered with hard pieces that protect their body, like the
starfish.
-
Some have
their body covered with spines, like the sea urchin.
3.- INVERTEBRATE ANIMALS WITHOUT PROTECTIVE
COVERING._______________________________________________
- They have
soft body.
WORMS
-
Worms are
invertebrates with long, soft bodies. Their bodies are usually ringed.
-
Some are terrestial,
they can live on land called earthworms. Others are aquatic, they live in the
water called sea worms.
-
Some are parasites.
They get into people´s stomachs when they eat or drink food contaminated with
worm eggs. To avoid catching intestinal worms, wash fruit and vegetables well
and wash your hands before you eat.
SPONGES
-
Sponges are
invertebrates with soft, irregular bodies full of pores.
-
Sponges
look like plants but they are animals.
-
They are aquatic,
they live in water.
-
Sponges can
not move. They stay fixed on the rocks in the ocean.
-
They eat
the substances that they filter through their pores.
JELLYFISH
- They have soft bodies
and tentacles.
- They are aquatic and
most live in warm water.
- They float in the sea.
ANEMONES
-
They have soft
bodies and tentacles.
-
They are aquatic
and most live in warm water.
-
They live
on rocks.
CORALS
- They have a hard covering.
- They are aquatic and
most live in warm water.
- They live on rocks.
ACTIVITIES
1.-Match
the group of invertebrates with their characteristics.
Worms They
have soft bodies with pores.
Poriferia Hard
pieces cover their bodies.
Echinoderms Some live on the rocks and other float
in the sea.
Jellyfish, anemones Some
are parasites.
and corals
2.- Fill
the gap.
Poriferia have ……………… bodies with lots of ……………, like
sponges.
They eat the ……………….. that they …………filter through
their pores.
They are ………………. and most live on the ……………. in the
sea.
