Which of the following observations is NOT scientifically testable?
-
Butterflies have pretty wings.
Yes! Pretty is an opinion, and can vary from person to person, so it is NOT scientifically testable. -
Butterflies have six legs.
No. This could be tested by counting the legs of a variety of butterflies. -
Butterflies can sting like bees.
No. A claim does not have to be true to be testable. Examination of a variety of butterflies would show that they do not have stingers. -
Most butterflies drink nectar from flowers.
No. This could be tested by observing the feeding habits of butterflies.
Explain more about it.
If I said that butterflies did not have six legs, you could show me physical evidence by counting their legs. After counting the legs, the physical evidence would show that butterflies have six legs.
If I said that I don't think butterfly wings are pretty, you could show me wings that you think are pretty, but I might not agree with your opinion. "Pretty" is not something that we can measure. What is pretty to one person might not be pretty to another, so it is not a testable property.

Rainbows are produced by:
-
Refraction
Partly correct. Light entering the raindrop is reflected off of the back surface. -
Reflection
Partly correct. As the light passes from air to water, and from water to air, the light is bent or refracted. Different colors are refracted different amounts, separating the colors. -
Both reflection and refraction
Correct! When you see a rainbow, the sun will always be behind you. (There are other, similar looking phenomena which you see when facing the sun, but they are not rainbows.) The sunlight enters each raindrop, is refracted (bent). Different colors are refracted different amounts. When the light hits the far side of the raindrop, part of it goes on through, and part of it is reflected back towards the sun (and towards you.) As it passes leaves the drop, the difference in density from water to air refracts (bends) the light even more, separating the colors into bands for the rainbow. -
Neither reflection no refraction
No. One or both take part in producing the rainbow.

Which of the following is a difference between a meteor and a comet?
-
Meteors are mostly made up of ice.
No. Meteors are made up of rock or iron, Comets are mostly made up of ice. -
Only comets have a visible tail.
No. A meteor is a meteoroid that has entered our atmosphere. As it burns, it also produces a tail. -
Meteors seem to move faster because they are closer.
Yes. Meteors are entering our atmosphere, so they are much closer to us that a distant comet. That makes them seem to move much faster. -
Comets are smaller than meteors.
No. Meteors are small, often the size of a grain of sand. Comets are much larger.

This snow fell when the temperature outside was 39°F. How can you get snow when the temperature is above freezing?
-
The wind made it feel colder, allowing it to snow.
No. While wind chill can make it feel colder, it does not actually make it colder. -
It was colder in the clouds where the snow formed.
Yes. Even when air temperatures at the surface are above freezing, the clouds can be much colder. If the air at the surface is not too warm, the snow can reach the ground without melting. -
Rain froze into snow when it hit the ground.
No. Freezing rain forms ice, not snow. Light, fluffy snow flakes form as they fall through the air, not after they hit the ground. -
This is really hail instead of snow.
No. Hail is made of large chunks of ice, not tiny flakes.

This is a lichen, which is actually a fungus and an algae living together. As it grows, it produces chemicals which dissolve some of the rock it grows on. This is an example of:
-
Erosion
No. Erosion means that the pieces of rocks are being carried away. The lichen is dissolving the rock, but not carrying it away. -
Weathering
Yes! Lichens cause quite a bit of weathering in rocky areas. -
Both erosion and weathering
No. The rock is not being moved, so it is not erosion. -
Neither erosion nor weathering
No. As the lichen dissolves the rock, that is an example of weathering.
