Warm Up-Accelerated Monday, February 1 It has been more than 80 years since the astronomer Edwin Hubble discovered that the universe is expanding. He was able to determine that fact by observing the speed and direction that galaxies are moving. Nearly all galaxies are moving away from our galaxy, and the more distant galaxies are moving away faster. That means that all of the galaxies in the universe (or at least the materials from which they were formed) were all together around 14 billions years ago and they have been moving apart ever since. That is a scientific fact. But the question of what is expanding is part of the big bang theory. According to this theory, what, exactly, is expanding. Which answer do you most agree with and why? a. Matter is expanding into a huge empty void b. Space is expanding or stretching, so the distance between galaxies is growing c. Space and matter are expanding, so galaxies are getting bigger and moving apart.

Explain who you agree with and WHY! Six student were talking about the sun. They had several different ideas. Here is what they said: Homework Due Today: * No Homework Sam: Our Sun is just an average start made up of hot glowing gas. Homework: Juanita: Our Sun is a huge ball of hot, glowing gas, but it is too close to us to be a star. * No Homework Tillie: Our Sun is one of the many stars found inside our solar system Skeeter: Our Sun was once a planet but is now a large burning ball Maggie: Our Sun is a major star. The other stars in the sky are sparks broken off from our sun. Diamond: Our Sun is a sun. It’s not a star. Suns are different from stars. Warm Up-Accelerated Thursday, February 4 Are we made of “Star Stuff?” A newspaper article reported that astronomers claim people are made of stardust. What does this mean? Pick the answer that best matches what you think “being made of stardust” means. a. “Being made of stardust” is not intended to be taken literally. It means that nobody really knows where atoms come from, and more than we know what “stardust” is. b. The stars produces dust that falls onto Earth. Ove millions of years this dust becomes incorporated into living cells. c. Most of the other elements that make up our bodies were formed inside stars or during supernova explosions d. Our Sun is a star and since humans eat plants or eat animals that eat plants, we are made mostly of stuff that originally came from the Sun.
