2. The Universe: How the Solar System Was Made

While watching the video take notes in your spiral. The notes should be a numbered list of the steps that lead to the formation of our solar system.

3. Solar System Formation
The solar system was formed when a cloud of gas and dust in space was disturbed by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust.

4. Solar System Formation
Squeezing made the cloud start to collapse, as gravity pulled the gas and dust together, forming a solar nebula.
Just like a dancer that spins faster as she pulls in her arms, the cloud began to spin as it collapsed.

5. Solar System Formation
Eventually, the cloud grew hotter and denser in the center, with a disk of gas and dust surrounding it that was hot in the center but cool at the edges.

6. Solar System Formation
As the disk got thinner and thinner, particles began to stick together and form clumps. Some clumps got bigger, as particles and small clumps stuck to them, eventually forming planets or moons .

7. Solar System Formation
Near the center of the cloud, where planets like Earth formed, only rocky material could stand the great heat.

8. Solar System Formation
Icy matter settled in the outer regions of the disk along with rocky material, where the giant planets like Jupiter formed.

9. Solar System Formation
As the cloud continued to fall in, the center eventually got so hot that it became a star, the Sun, and blew most of the gas and dust of the new solar system with a strong stellar wind. By studying meteorites, which are thought to be left over from this early phase of the solar system, scientists have found that the solar system is about 4.6 billion years old!
