Learning intentions

1. To name all the names of all of the Planets.

2. To understand what Orbit means.

3. To describe all the planets and tell me what they are made from.

14/05/2020There are nine planets in our solar system:

Mercury

Mars

Jupiter

Saturn

Neptune

Uranus

Pluto

VenusEarth

14/05/2020

The Earth orbits the sun every…

…year (365 1/4 days)

14/05/2020

The Earth is kept in orbit by the force of…

Gravity

…and by the fact that is is moving at a high velocity

14/05/2020

Gravity also keeps the moon in orbit around the Earth. The moon orbits the Earth every…

…month (28 days)

14/05/2020

Gravity is ________ if the planet has more mass:

Earth

Jupiter

14/05/2020How much of the moon we see depends on where the moon is in its orbit:

The moon is a “natural satellite”. A satellite is anything the orbits the earth

Artificial satellites have four main uses:

– Communications

– Monitoring the weather

– Observing the Earth

– Exploring the solar system

14/05/2020

The Earth is tilted on an axis

North pole

South pole

14/05/2020

The Earth spins on its axis every ___ (__ hours)

14/05/2020

Because of this spin the sun rises in the ______ and sets in the ______

14/05/2020

The sun appears lower in the _______ than it does in the ______:

Winter

Summer

Longer shadows in winter

14/05/2020

While the Earth is spinning the side that faces the sun is in ________

14/05/2020

The Earth is divided up into the northern hemisphere and the southern hemisphere:

Equator

Northern hemisphere

Southern hemisphere

14/05/2020

The tilt of the Earth on its axis is also responsible for the seasons:

14/05/2020

Two things happen because of this tilt:

1) The days are longer during the summer

2) The weather is warmer during the summer

14/05/2020Eclipses

1. A solar eclipse:

2. A lunar eclipse:

14/05/2020Solar systems, galaxies and the Universe

OUR SUN is one of millions of stars that orbit the centre of…

THE MILKY WAY, which is one of a billion galaxies that orbit AND move away from the centre of…

THE UNIVERSE

(Basically, everything in the universe orbits around something else)

Learning Outcome

1.To know that the Earth orbits the Sun once a year and that the Moon

takes approximately 28 days to orbit the Earth.

2. To know that the Earth spins on its own axis once every 24 hours.

14/05/2020

The Earth

The Earth is round, like a ball, but it is also slightly squashed. We say that its shape

is roughly spherical.

The Earth travels around the Sun once every year.

The Earth also spins on its own axis. The axis is an imaginary line through the

centre of the Earth from the North Pole to the South Pole. The Earth spins round

once every 24 hours. This causes day and night on Earth.

•It is day on the part of the Earth that is facing the Sun.

•It is night on the part of the Earth that is facing away from the Sun.

14/05/2020

The Moon

The Moon is roughly spherical, but it is a lot smaller than the Earth.

The Moon travels around the Earth. It goes round once every 28 days.

We only see the part of the Moon that is lit by the Sun. So

sometimes we see the whole Moon and sometimes we only see

part of the Moon.

14/05/2020

The Sun

The Sun is a star and gives out heat and light.

It is roughly spherical in shape and is much, much bigger than the Earth.

14/05/2020

The planets

The Earth is just one of eight planets that

travel around the Sun. The other planets are called Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune.
