What happens when you place a container of water in the beam of a ray of light?
Light is mostly refracted.
Light mostly bounces off it.
Light is mostly absorbed.
Light is mostly reflected.
What is the best description of electromagnetic radiation?
Energy waves bouncing off the surface of an object
Energy that travels in the form of electromagnetic waves
A form of energy that is part of the electromagnetic spectrum and exhibits wave-like behavior as it travels through space
The ability for light to pass through so that objects behind can be seen distinctly
Scientists use the light-year to describe the relationships between objects in space. What does a light-year measure?
the distance that light can travel in one year
the brightness of light that travels through space
the number of years it takes light to travel to Earth

Christopher wants to investigate which of three brands of food his pet hamster Champ prefers. Which of the following is the best way for Christopher to investigate this question?
Place each type in Champ's cage at the same time. Observe which brand he tries first.
Over three days, feed Champ each type of food. Observe Champ's behavior each day.
Place each type in Champ's cage at the same time. Observe which brand he eats the most of.
Over three days, feed Champ each type of food. Observe how long it takes Champ to eat the food.
Sean is planning an investigation to test which materials conduct electricity. To do this, he will set up a simple circuit using a battery, wire, and a light bulb. Then, he will complete the circuit with objects made from different materials and he will observe whether the bulb lights up. In this experiment, what is the outcome variable (dependent variable)?
whether the bulb lights
how bright the bulb glows
the strength of the battery used
the object used to complete the circuit
What is the center of our solar system?
The sun
Earth
Jupiter
Saturn
Why do the planets orbit the sun?
They don't, the planets orbit the Earth
Because Science
The sun is so massive that it has a very large gravitational pull, which causes objects to orbit it
Because they want to
If Earth is 1 AU away from the sun, and Neptune is 30 AU away from the sun, what does this mean?
Neptune is 30 years older than the Earth
Neptune is 30 times larger than Earth
Neptune is 30 times farther away from the sun than the Earth
Why do scientists use scale to study the Solar System?
The solar system is too large to study without using scale
The solar system is too small to study without using scale
Scientists don't need to use scale because we have satelites
All of the above
Which physical property of a star is most directly related to its color?
Apparent magnitude
Temperature
Size
Luminosity
What does the apparent magnitude of a star measure?
The star's actual size
How bright the star appears from Earth
The star's temperature
The star's distance from the Sun
If a star appears red, what can you infer about its temperature compared to a blue star?
It is hotter than a blue star
It is cooler than a blue star
It is the same temperature as a blue star
Color does not relate to temperature
What is the main difference between sunspots and solar flares?
Sunspots are cooler, solar flares are sudden bursts of energy
Sunspots are hotter, solar flares are dark spots
Sunspots are on the Sun’s core, solar flares are on the surface
Sunspots are made of gas, solar flares are made of dust
What is a solar prominence?
A dark spot on the Sun’s surface
A loop of gas that extends from the Sun’s surface

The farther star is more bright
Both stars have the same brightness
Brightness cannot be determined
