The science of Astronomy is interesting and varied. There are a lot of resources for it for kids who are interested in the planets, the solar system, the universe and everything else that’s part of this exciting science. For children, many parts of it are magical and thus they are drawn towards the moon, the stars and far distant galaxies.

The moon is Earth’s only satellite. It takes about 27 days to orbit the Earth. Being so near, it has hosted the only human footsteps on a space object other than the Earth. Gravity between the moon and Earth causes the tides. It’s brightness in the night sky attracts many children to learn more about it.

Then there’s our sun. Earth is quite far from the sun. The distance fluctuates between about 91 million miles and about 94 million miles. That’s because Earth’s orbit around the sun isn’t a circle, it’s an ellipse. If there were no sun, we wouldn’t be alive. Our light and heat comes from the sun. Over 98% of the total stuff in our solar system is in the sun. Think about how small a person is compared to that.

We live in the Milky Way Galaxy. It’s full of space stuff. Even with all this stuff to fill it, it’s mostly empty. At over 100,000 light years wide and 3,000 light years high, that means the galaxy contains a whole lot of nothing. The center of our galaxy is about 30,000 light years from Earth. Even with all that space there are about 100 billion stars in the Milky Way. In fact the galaxy was named for the thick group of stars in the main portion of it. People thought it looked like a stream of milk, so called it the Milky Way. There are four types of galaxies – elliptical, lenticular, irregular and like the Milky Way, spiral.

There is a lot of information about astronomy for kids on the Internet. Kids could spend hours wrapped in detailed 3D representations of the universe around us.

Outer space and the solar system is one of the most interesting topics discussed in school because of the countless colorful heavenly bodies occupying the universe and the idea that there is actually something else outside of our world.

In the few decades since space exploration began, probes have reached the far regions of the solar system. The solar system is the group of celestial bodies, including Earth that orbits around the Milky Way galaxy. Some hundred billion stars can be found in the universe while more than 1,000 comets have been observed regularly through telescopes.

To give this topic a little twist, here are tips to have students get it.

1. As introduction to the subject, bring your students out of the classroom (at both daytime and nighttime if its possible) so they can see what makes up the sky. Explain that the solar system is made up of our sun and all of the heavenly bodies that travel around it. Once they have familiarized themselves to the concept of space and the solar system, you can start moving on.

2. The ten planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, and Xena) differ in characteristics. You can use a table to show these differences and characteristics. After showing how each is special from the other, you can let them pick a favorite planet, draw it the way they want it and explain why they chose it from the rest.

3. For more than 300 years there has been scientific discussions of the events that led to the formation of the solar system. And since it could be quite time-consuming to talk about the theories concerning the origin of life in the solar system, you may use film or other visual presentations as tools to better explain it.

4. A telescope is another effective device used to magnify or enlarge the image of a distant object. It is a very important tool for astronomers. It enables them to see much farther into space than is possible with the human eye. What you can do is bring a telescope you can share with your students so everyone can have a glimpse on whats out there in space through a very informal activity.

What is space exploration? The age of space exploration began in the sixth decade of the 20th century. Since that time, robot probes and human beings have ventured beyond the limits of the Earths atmosphere. Today, space explorations include the investigation of celestial objects ranging in size from cosmic dust to the giant planets of the solar system. Because of technology, humans are continuously discovering more about life and forces in space. The possibilities are endless.

Outer space and the solar system may be a very interesting topic but its long history of theoretical and practical developments can fuel a lot of questions. The key to space exploration lay in the production of the rocket engine, which made possible the lofting of objects beyond the Earths atmosphere. With this subject, remember you are teaching your students that the field of space exploration and the solar system relies heavily on communication and technology.
