One benefit of presenting information in a video rather than in text is that a video can
include interviews with experts.
show close-ups of images.
bring concepts to life.
The first person to map the Milky Way Galaxy using radio waves was
Sir Isaac Newton.
What information could a video of an exploding star provide that a text could not?
The video could tell what happens after an explosion.
The video could tell how exploding stars affect space.
The video could show what the star looks like in motion.
Ricardo read this excerpt from A Black Hole Is NOT a Hole by Carolyn Cinami DeCristofano.
Discoveries of black holes exploded in the late 1900s and early 2000s. What scientists found reads like a cast of characters for a mixed-up fairy tale. First they discovered the small ("Baby Bear") black holes, then the giant "Papas." But where were the medium "Mama Bear" black holes? It just didn't make sense that there would be smalls and larges but no mediums. Astronomers began the search, and found them. There's just one size that still hasn't been found, even though it has been predicted. The tiniest of all, the "Tom Thumbs" of the black-hole world, have yet to be discovered—if they even exist.
After reading the excerpt, Ricardo made a text-to-text connection. Which example is a text-to-text connection?
Ricardo had watched a video about big discoveries in space, so he had some background information on the subject of the excerpt.
While reading the excerpt, Ricardo remembered playing a game when he was a child that had a “Papa Bear,” “Mama Bear,” and “Baby Bear.”
While reading the excerpt, Ricardo remembered hearing about black holes in school, and it made him interested to learn more.
Before watching a video about black holes, it is important to
think about how the video’s director captured images of black holes.
predict what scientists might discover about black holes in the future.
write an essay that connects the video to a text about black holes.
In the 1930s, Grote Reber became known for
solving a problem with transatlantic telephone service.
discovering the location of the first known black hole.
inventing a telescope that could detect radio signals.
Read this excerpt from A Black Hole Is NOT a Hole by Carolyn Cinami DeCristofano.
Reber had just one little problem. To explore the radio energy, he needed a radio telescope—a telescope that could detect invisible radio energy—but there was no such thing at the time. So he invented one. He built it in his backyard in Wheaton, Illinois. Late into the night, Reber probed the sky with his new telescope, using it to locate the source of the mysterious radio energy.
Reber mapped these signals from the sky and shared his findings. Astronomers followed up with new investigations and soon began reporting more signals. Over time, with better radio telescopes, they found that some radio sources appeared as paired patches, one on either side of a tiny dot. They called these sources "radio galaxies." They also discovered other, more starlike sources—intense dots of radio energy without patches. How strange. What could these quasars (short for "quasi-stellar radio sources") be? Were they related to the radio galaxies?
According to the excerpt, how did astronomers use Reber’s findings to add to the knowledge of black holes?
Astronomers used Reber’s radio telescope and renamed his discoveries “radio galaxies” and “quasars.”
Astronomers improved on Reber’s radio telescope and made new discoveries to prove his findings were wrong.
Astronomers used Reber’s maps of the signals from the space to locate radio galaxies.
Which pair of sentences best describes a scientific discovery in A Black Hole Is NOT a Hole by Carolyn Cinami DeCristofano?
First, scientists went searching for black holes in the universe. Next, the same scientists discovered a supermassive black hole.
First, scientists studied radio waves coming from space. Next, other scientists used their discoveries to identify black holes.
First, scientists studied radio waves coming from space. Next, the same scientists discovered black holes.
The discovery of supermassive black holes began with the discovery of
the Milky Way.
radio energy from space.
the Big Dipper.
Why were astronomers interested in studying radio waves in the 1980s and 1990s?
The radio waves were coming from the center of the Milky Way.
The radio waves were causing static on the transatlantic telephone service.
The radio waves were visible and could be seen in the sky above Earth.
