Which of the following is likely a sign that it will rain soon?
-
Rising temperature
No. A warm air mass moving into your area might bring rain, but it also might bring sunny weather. Rising temperature by itself is not a good indicator of rain. -
Decreasing humidity
No. The humidity at ground level does not play much of a role in the formation of rain in the clouds. Just before it rains, the precipitation could cause the humidity to increase, but it would not cause it to decrease. -
Wind out of the west
No. Any weather front moving in from the west could cause winds, even if it was bringing clear, sunny weather. -
Falling barometric pressure
Yes! Low pressure fronts are commonly associated with rain and storms, so falling barometric pressure is a good indicator that rain may be on the way.

Eyeglasses and camera lenses change the path of light to focus an image. Which of the following is responsible for that change?
-
Refraction
Yes! Refraction bends light as it moves from one substance to another. By bending the light, we can use refraction to focus the image in a camera, or to correct the focus of the lens in our eyes. -
Reflection
No. While some light is reflected from a lens, that does not help us focus the image. -
Absorption
No. The lens is clear, telling us that very little of the light is being absorbed. Absorption does not help the lens focus. -
Diffusion
No. Diffusion is the scattering of light as it is reflected in many different directions. Diffusion would make the image cloudy and blurry, not help focus it.

Why are trees an important part of the water cycle?
-
Trees need water.
No. While trees do need water, that is not why they are part of the water cycle. -
Transpiration
Yes! In order to get nutrients up to the top of a tree, it has to let water evaporate from its leaves. This process is called transpiration. One tree can put hundreds of gallons of water into the air as water vapor every day. -
Trees help prevent erosion.
No. While trees can help prevent erosion, that is not why they are part of the water cycle. -
Condensation
No. Trees are not a major source of condensation.

Which of the following is NOT a function of your skeleton?
-
Produce insulin
Yes! Insulin is produced by the pancreas, not by bones. -

Notice that the very back point on this Mule Deer's antlers is split. This is a genetic trait which is becoming more and more common because hunters would rather shoot deer with perfect antlers. This is an example of:
-
why hunting deer is a bad idea.
No. Actually, deer hunting is very important. Because we have killed off many of their natural predators, if hunters did not control their population, large numbers of them would starve to death. -
an adaptation that improves an organism's chance for survival.
Yes. Because hunters are less likely to shoot it, this deer is more likely to survive long enough to reproduce, passing this trait on to its offspring. -
an acquired trait.
No. This is a genetic trait, not an acquired trait. -
why antlers are more useful than horns.
No. Antlers and horns serve different functions, but both are useful to the animal that has them.
