Test: 5th Grade Science

1.

Four students are making claims about stars and their apparent brightness.

  • Ursula: "The star that appears brightest to us is the Sun because it is the largest in the galaxy."
  • Gretel: "The Sun appears to be the brightest star because it is the closest to Earth."
  • Hansel: "The Sun is the brightest star when looking from Earth because it is the hottest."
  • Phoebe: "I have seen brighter stars than the Sun; it isn't that great."

Their teacher shares the following information from NASA, "Of course, the star that appears the brightest to all of us on Earth is the Sun. Although it is a rather typical star, not all that different from many of the ones you see at night, we live so close to it that it outshines everything else. Even the next closest star is more than a quarter of a million times farther from Earth, so it is not surprising that the light from the Sun overwhelms that from other stars."

Which student's argument is supported by the teacher's research?
