Meet Our Solar System: A Rhyming Children's Book About Sun, Moon, & The Planets. Fun Facts & Pictures for Kids Years Old eBook: Mindy Robinson. A Neptune-like world in a distant orbit explains some solar system riddles. meet Our Solar System. Remember, kids—planets, stars, comets, and asteroids can't really talk. But if they could, here is what they might say! “Hi, Earth children!.

A solar system consists. A solar system consists of a star and the objects that travel around it. Our Solar System includes our central star, the Sun, the planets, moons, asteroids, meteors and comets. The inner planets are Mercury, Venus, Earth and Mars.

The outer planets are Jupiter, Saturn, Uranus and Neptune. A planet is a large spherical satellite of a star A planet is a large spherical satellite of a star 2 LOL: How Big Are the Planets Most astronomical objects things in space are too big and too far away to study up close and in person.

We use scale models, smaller versions, to help us understand these objects better. Most astronomical objects things in space are too big and too far away to study up close and in person. The inner planets are closer together, and are closer to the sun. The outer planets are really spread out and much bigger than the inner planets The outer planets are really spread out and much bigger than the inner planets 5 LOL: The Earth Rotates every 24 hours and this caused day and night The Earth Rotates every 24 hours and this caused day and night Rotation- is when the Earth is spinning on its axis.

Rotation- is when the Earth is spinning on its axis. The Earth rotates counterclockwise The Earth rotates counterclockwise The Earth orbits or Revolves around the sun counterclockwise.

The Sun also produces solar flares- very large outbursts of energy which leave the Sun. When these flares reach the Earth, they can disrupt Earth satellites, interrupting GPS and mobile signals. Its diameter is about 1, km, which means that more than Earth could be lined up along the Sun's equator, and its mass is more thantimes that of Earth.

But compared to other types of stars, the Sun is quite average: The Sun produces its energy from thermonuclear reactions taking place at its very centre, where the temperature reaches 15 million degrees.

Meet Our Neighbours: Sun

This process, which involves "burning" hydrogen and transforming it into helium, has been going on for the last 4. This makes them appear darker than the surroundings.

The spots always appear in pairs with opposite magnetic polarities the four irregular shaped areas on the tactile model. The activity of the Sun can be measured by the number of spots appearing on the photosphere during a particular year. This activity varies periodically along a cycle of about 11 years.

The last minimum occurred in and the next maximum is expected in However, between two consecutive cycles, the magnetic field reverses itself; so a complete cycle is actually 22 years long.

Other remarkable features of the sun are the "solar prominences" represented by loops of thin thread at the edge of the tactile model. They are actual bridges of matter between solar spots, shaped by the powerful magnetic field of the sun. Some of them can be lifted above the photosphere by as much askm, which is almost the distance between the Earth and the Moon.

They can also be completely disrupted by violent explosions before all the matter has time to fall back onto the surface, in which case some of the matter is sent flowing throughout the solar system. The sun has an atmosphere, called the "chromosphere" because of its dark orange colour. It can only be seen during natural or artificial eclipses as a thin orange layer around the much brighter photosphere.

Finally, above the chromosphere, lies the "corona", a region containing very rarefied gas heated up to one million degrees by a process which is still poorly understood.

Like the chromosphere, it can only be seen during an eclipse as a shiny halo with bright streaks of hot plasma. Full Activity Description Prior to the activity: Ask students what they know about the Sun, introducing it as the star closest to Earth and a hot ball of "burning" gas. Tell students they will be making models of the Sun to investigate its different features. Put the students in groups of 5 ideally 3 non-visually impaired to 2 visually impaired.

Close supervision is important. Follow each group and explain each of the tactile elements and their correspondence to each object feature.

Understand the different needs of each group of students to promote interaction between the students during the building of the tactile image — visually impaired students need to be familiarized with the different materials involved.
