Why is color not a reliable way to identify minerals?
-
Many minerals occur in several different colors
Yes. This is the mineral quartz. Quartz can be clear, white, black, yellow, purple, and other colors, so its color is not reliable for identification. -
It is difficult to tell the difference between color and luster.
No. Luster tells us how the mineral reflects light, and has nothing to do with its color. -
Some minerals are clear, and don't have any color.
No. Even clear minerals like quartz can be found in different colors due to impurities and imperfections. -
Actually, color is a good way to identify minerals.
No. Color is not a reliable way to identify minerals.

What is the difference between speed and velocity?
-
Speed is faster.
No. An object's speed is part of its velocity. -
Velocity has to be in a specific direction.
Yes! An object's speed is measured in distance per time, such as 20 miles per hour. Its velocity must include a direction, such as north at 20 miles per hour. -
They mean the same thing.
No. The two terms have different meanings. -
Speed is a general term and velocity is a scientific term.
No. Both terms are used in science, and they mean different things.

Which of these is NOT an example of a renewable energy source?
-
Wood
No. Because we can grow more trees, wood is a renewable energy source. -
Coal
Yes. It takes millions of years for coal to form, so it is not considered a renewable energy source. -
Hydroelectric power
No. Thanks to the water cycle, water is added to the lake above the dam, making this a renewable energy source. -
Wind energy
No. Wind energy is constantly renewed by uneven heating of the Earth.

In testing this piece of quartz, I found that it would scratch glass. What property was I testing?
-
Hardness
Yes! Hardness is a substance's resistance to being scratched. With a hardness of 7, quartz is hard enough to scratch glass. -
Cleavage
No. Cleavage is the tendency of a mineral to break along planes of weakness to produce pieces with flat, smooth sides. Cleavage involves breaking, not scratching. -
Fracture
No. Fracture is a property of minerals that do NOT break along planes of weakness to produce flat, smooth sides. This involves breaking, not scratching. -
Streak
No. Streak is a test to see the color of a mineral when it is ground into a powder by scratching it on a porcelain streak plate. For streak, we are powdering the mineral, not scratching another substance.

You have probably seen patterns of light like this in a pool of water. What causes it?
-
Absorption
No. If the light was being absorbed, the pattern would be dark instead of bright. -
Diffusion
No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the entire area brighter, not a specific pattern. -
Reflection
No. While the light has to reflect back to your eye for you to see it, reflection does not cause this pattern. -
Refraction
Yes! Refraction bends light. Waves and ripples on the surface of the water act just like the curved surface of a lens. This bends the light into patterns that have shapes similar to the ripples on the water's surface.
