1) The James Webb Space Telescope will be the largest telescope ever put into space and will replace the Hubble Space Telescope. It will be launched into orbit beyond Earth's moon, where it can work in an ultra-cold environment, protected from the heat of the Sun. Unlike Hubble, which collects information primarily from visible light, the Webb Telescope will use infrared-detecting technology to monitor space.
How will the new technology of the Webb Telescope enhance the data scientists will be able to collect from outer space?
It will collect highly detailed data about nuclear activity deep within our Sun.
It will detect high-energy ultraviolet radiation emitted from supernovae and black holes.
It will avoid the distortion from the atmosphere and give scientists more accurate data.
It will see farther out into space to give scientists insight into how the universe was formed.
How has our ability to send remote-controlled devices to planets such as Mars enhanced our understanding of the universe?
It has made it possible for astronauts to visit distant planets in person.
It has limited our exploration to planets with atmospheres similar to ours.
It has allowed us to visually explore distant planets without endangering anyone.
It has enabled us to collect soil samples from distant planets and bring them back to Earth.
The chart below shows the average distance in astronomical units between each planet and the Sun.
Which planet would make the closest approach to Earth as the planet orbits the sun?
Mars
Mercury
Jupiter
Venus
Rachel is learning about electromagnetic radiation that comes from the sun.
What types of electromagnetic radiation does the sun emit?
Gamma rays and ultraviolet radiation
Ultraviolet radiation only
Infrared, visible, and ultraviolet radiation
All types of electromagnetic radiation
As part of his job at the U.S. Forestry Service, Scott uses satellite images to identify forest areas that have been cleared due to logging. The satellite images, which show show forests appearing cooler and cleared areas appearing warmer, are produced using electromagnetic radiation.
Which part of the electromagnetic spectrum does Scott’s technology MOST LIKELY use?
Infrared radiation
Gamma
Radio
Visible
Carla is learning about types of electromagnetic waves. What is the difference between a microwave and a gamma wave?
Microwaves are common and gamma waves are rare.
Microwaves are silent and gamma rays are audible.
Microwaves were invented by humans and gamma waves were not.
Microwaves and gamma waves have different wavelengths.
Wavelength and frequency are related. Gamma rays, microwaves, visible light, and infrared rays all have different frequencies.
Which of the following lists them in the correct order from longest wavelength to shortest wavelength?
Visible light, microwaves, infrared rays, gamma rays
Gamma rays, infrared rays, microwaves, visible light
Infrared rays, microwaves, visible light, gamma rays
Microwaves, infrared, visible light, gamma rays
When NASA scientists communicate with the mars rover, shown in the illustration, they use electromagnetic radiation with a long wavelength and low energy.
Which type of radiation do they MOSTLY LIKELY use?
X-rays
Visible
Radio
Infrared
How is ultraviolet light different from the light emitted by a flashlight?
Ultraviolet light is brighter than the light from a flashlight.
Only light from a flashlight can travel through a vacuum.
Ultraviolet light is invisible to the human eye.
Ultraviolet light has a longer wavelength than the light from a flashlight.
The illustration below shows what happens when light is passed through a prism.
What type of light passed through the prism?
Yellow light
Infrared light
White light
Ultraviolet light
The illustration below shows how light reflects off of a shiny surface such as a mirror.
Based on the Law of Reflection, which of the following can you conclude from the illustration?
Light will reflect in the direction indicated by D.
The angle formed by C and D equals the angle formed by D and E.
The angle formed by C and D equals the angle formed by C and B.
Light will refract after it strikes the shiny surface.
As light passes through the air, some of the light energy is transferred to the particles in the air. What process is occurring with this transfer of energy?
Absorption
Refraction
Transmission
Reflection
Light can sometimes create an optical illusion. For example, you may see something under water and reach into the water to pick it up. However, the object is not where you thought it would be. What property of light is responsible for this optical illusion?
Reflection
Transmission
Refraction
Absorption
Kareem told his friend about the beautiful rainbow he saw just after a rainstorm. Kareem then explained to his friend how a rainbow forms. What was Kareem’s explanation?
The light waves were refracted by moisture in the air and separated into colors.
The intensity of light increased as the waves passed through tiny droplets of water.
Tiny droplets of water reflected the light waves that struck them.
Light traveled faster after the rainstorm because of the moisture in the air.
What happens when a white object that cannot be seen in the dark is illuminated?
Light is given off by the object.
Light is reflected by the object.
Light is refracted by the object.
Light is absorbed by the object.
The image below shows light entering water.
Which statement explains why light bends when it reaches the surface of the water?
Light bends because the water reflects some of the light that reaches it.
Light bends because water changes its speed when it moves from air into water.
Light bends because water changes the amount of energy it carries.
Light bends because water absorbs some of the light that reaches it.
The drawing below illustrates a wave in motion.
What is the name given to the substance through which a mechanical wave travels?
Crest
State
Medium
Frequency
Sound waves can move at different speeds.
What can affect the speed at which sound waves travel?
The amplitude of sound waves
The frequency of sound waves
The material through which sound waves travel
The distance over which sound waves travel
In the desert air, sound travels at 358 meters per second. In the polar air, sound travels at 330 meters per second.
What can you conclude from this information?
The speed of sound is constant.
Sound waves travel at the same speed everywhere on Earth.
Sound waves travel fastest in a vacuum.
The temperature of the air affects the speed of sound.
Sound waves travel the fastest through solids.
What will slow the speed of a sound wave?
A decrease in the distance the sound travels
A decrease in the density of the material through which it is passing
An increase in the density of the material through which it is passing
An increase in the distance the sound travels
Sunlight travels all the way from the Sun through Earth's atmosphere to the ground. However, sunlight does not always reach the bottom of the ocean.
Why is it impossible for sunlight to reach the bottom of the deepest oceans?
Light is reflected by deep ocean currents.
Light is reflected off the ocean's surface and back into the air.
Light travels more slowly in water and is absorbed.
Light changes speed as it gets farther from the Sun.
Look closely at the graph below of the speed of sound waves in air and water.
What can you conclude from the data on this graph?
The speed of sound waves depends on the medium through which they travel.
Both air and water transmit sound waves at the same speed.
The speed of sound waves is constant.
Sound waves travel faster than light waves.
A scientific hypothesis requires empirical evidence to support the hypothesis.
