Science and the Universe

Which statement below best describes the Universe?

• The Universe is a black hole made of dark matter.

• The Universe is a giant cloud of dust and gas in space.

• The Universe contains the Milky Way galaxy which contains most of the stars in space.

• The Universe contains many billions of galaxies and each galaxy contains many billions of stars.

An astronomer is looking at a recent picture of space, that was taken by the Hubble Space Telescope. He describes the image by saying that it has a collection of many billions of stars bound together by gravitational attraction. What is the astronomer mostly like seeing in the picture?

• moon

• galaxy

• planets

• solar system

Jada, Kevin and Joshua are placing cards on a chart that shows the approximate size of Earth, the Milky Way, the Moon, the Sun and an asteroid. Their teacher put the Earth card in the correct place. Which point on the chart best represents the approximate size of an asteroid?

• point 1

• point 2

• point 3

• point 4

Gustavo is doing a presentation in class comparing the objects of space by their relative sizes. If “Z” represents a planet, what would “Y” most likely represent?

• A solar system because it contains planets and stars.

• A nebula because that is what the planets formed from.

• A galaxy because it contains billions of stars and the planets.

• A universe because it contains billions of stars and the planets.

The image was taken by a space telescope. Which of the following options best describes what is being observed?

• The image is a nebula that is thousands of light years wide, containing stars, galaxies, and planets.

• The image is a galaxy, that is thousands of light years wide, containing solar systems, nebulae, planets and millions of stars.

• The image is the Universe, that is thousands of astronomical units wide, inside a galaxy containing all the stars and planets.

• The image is a solar system, hundreds astronomical units wide, that contains a star in the center with planets, moons, and asteroids orbiting it.

Ethan learned that astronomers use satellites to study the Universe. Which of the following statements describes how another type of scientist can use satellites in their related field?

• Volcanologist use satellites study the Earth's core.

• Biologists use satellites to study the development of large weather systems, like hurricanes.

• Due to the heavy tree cover, geologist use satellites to study animal behavior in the amazon.

• Due to the remoteness and darkness of the polar regions, climatologist use satellites to collect data on climate change.

Satellites are used mainly to gather light from cosmic objects. The Hubble telescope is shown in the drawing below. As it travels, Hubble's mirror captures light and directs it into its several science instruments. How is this technology advancing our understanding of the universe? A. B. . C. D.

• It is capable of counting individual atoms in a substance in order for scientists to study them.

• It is capable of sending audio communication to other planets in our solar system for them to respond

• It has already sent pictures that show other planetary systems in the universe in order for scientists to study them.

• It is capable of sending clear, distinct images of distant objects, like other galaxies in order for scientists to study them.

When studying celestial bodies, scientists examine satellite images of the same object made with different waves of the electromagnetic spectrum. How does using different types of electromagnetic waves provide a more complete understanding of the celestial bodies?

• EM waves have the same energy which provides unique information.

• EM waves travel at different speeds which provide unique information.

• EM waves travel the same distance which provides unique information.

• EM waves have different wavelengths which provide unique information

After the first satellite, Sputnik, was launched in 1957 the world has been putting satellites into space for the purpose of learning more about our planet. Meteorologists use these satellites to study global weather patterns and gain a better understanding of weather predictions. What choice below should meteorologists used to see patterns of heat flow through the atmosphere?

• Infrared waves, because the wavelength is lower than visible light.

• Ultraviolet waves, because the wavelength is lower than visible light.

• They will have to use gamma rays to determine the thermal energy in the atmosphere.

• They will have to use different kinds of sensors because the electromagnetic spectrum produces similar types of radiation.

Which statement below best explains why the scientists use different methods in their field of science?

• Scientists conduct investigations using a method that is based on what tools and equipment they like to use in their field.

• Scientists conduct investigations using a method that will match the data they have recorded in order to prove their theory

• Scientists conduct investigations using a variety of methods to gather information that best fits the data they need to support their hypothesis.

• Scientists conduct investigations using a method specific to their field to gather information that is unique to their research and form an explanation.
