A star is a massive, bright, sphere of very hot gas called plasma which is held together by its own gravity.
Stars radiate energy created from nuclear fusionwhich is a process that takes place in a star's core and involves hydrogen fusing burning to make helium. As a star is near the end of its life, it begins to change the helium into heavier chemical elements, such carbon and oxygenand the star will begin to change color, density, mass and size.
The nearest star to Earth is the Sunwhich is classified as a G2 yellow dwarf star.
It is about This means it takes light from this star 4. Using the newest, fastest space probe propulsion systems would still take a craft about 75, years to get there. There are approximately billion stars in our Milky Way Galaxy alone. Each galaxy contains hundreds of billions of stars and there is estimated to be over billion galaxies in the universe.
So the total number of stars in the universe is mind boggling, estimated to be at least 70 sextillion and possibly as high as sextillion, that's ,,,,!!!!!
Stars are usually between 1 and 10 billion years old. Some stars may even be close to the age of the observed Universe at nearly Binary stars and multi-star systems are two or more stars that are gravitationally linked, they orbit around each other.
Stars form in nebulas, which are large gases areas. As gravity attracts more and more gas, young stars called protostars start to form in thick molecular gases cloud areas of the nebula.
Once nuclear fusion has began in the core, a star is sufficiently fuelled to spend the majority of its life as a main sequence star in its most stable form. The most common star, are red dwarfs. They are less than half the size and mass of our Sun, and burn their fuel very slowly so live longer than any other type of star, over billion years.
Red dwarfs are cooler than most stars and so shine less, eventually getting dimmer they do not explode. A brown dwarf forms if a star cannot get hot enough to reach nuclear fusion. Its failed to become a proper star but is still not a planet because it does glow dimly.Number the Stars By: Lois Lowry The genre of this book is historical fiction.

The Report Card Teacher's Guide Encourage elementary and intermediate students to think about educational issues with the discussion topics, activities, and projects in this teacher's guide for The Report . I also initiated and led an innovative multi-school project that introduced educators and learners to Knowledge Building pedagogy and technology.
Co-design sessions with these educators yielded student-driven collaborative inquiry learning experiences, framed within a project-based learning model, that culminated in student-created multimedia.
