This is the Navajo Sandstone, a huge layer of rock that forms the cliff in our back yard. The strange patterns in the sandstone tell us that at the time they were formed, this area was a desert, and the sand formed sand dunes. What kind of rock is sandstone?
- 
IgneousNo. Igneous rocks are formed from molten lava or magma, not from sand.
- 
SedimentaryYes! Sedimentary rocks are made up of bits of other rocks that have been deposited by wind, water, ice, or gravity. This sand was deposited by the wind, making this a sedimentary rock.
- 
MetamorphicNo. Metamorphic rocks have been changed by heat and/or pressure. If this sandstone was exposed to tremendous heat and pressure, it could change into a metamorphic rock called quartzite.
- 
Sandstone is not a rock.No. Sandstone is a naturally occurring solid that forms large layers in the Earth. It is a rock.

- 
Trees need water.No. While trees do need water, that is not why they are part of the water cycle.
- 
TranspirationYes! 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.
- 
CondensationNo. Trees are not a major source of condensation.

What season is the area that the arrow points to having?
- 
WinterYes! Even though that area is in daylight, the Earth's axis in that hemisphere is pointing away from the Sun. It gets less direct light, and has shorter days.
- 
SpringNo. For spring, the Earth's axis for that hemisphere would be in between pointing towards the Sun and away from the Sun.
- 
SummerNo. Although it is daytime in that area, the Earth's axis in that hemisphere is pointing away from the Sun. It gets less direct light, and has shorter days.
- 
AutumnNo. For autumn, the Earth's axis for that hemisphere would be in between pointing towards the Sun and away from the Sun.

Which of the following statements is scientifically testable?
- 
These alligators are scary.No. Being scary is not a physical property. Instead, it is an opinion. Some people might think they are scary, while other people might think they are not.
- 
These alligators have sharp teeth.Yes! Careful observation would show that all three of these alligators have very sharp teeth. Anyone who put their hand into the mouth of these alligators would find out quickly that sharp teeth are a measurable, physical property that is scientifically testable.Remember that scientifically testable properties are going to be the same, no matter who tests them. For example, these alligators each have four legs, scaly skin, and lungs for breathing air. They are carnivorous, which means that they eat other animals. They are reptiles, and they lay eggs. All of that information is based on physical evidence that can be checked and verified. You could count their legs, examine their skin, etc. These things are scientifically testable. On the other hand, opinions are a property of the observer, not the object. I may think alligators are interesting. Someone else may thing they are scary, or ugly, or boring. You could test different people, to see if they think alligators are scary, but you can't test the alligator to see if it is scary. Opinions are not scientific evidence about the object. 
- 
These alligators have ugly eyes.No. Again, this is an opinion, not a measurable, physical property. I happen to think that alligators have pretty eyes.
- 
These alligators are lazy.No. Lazy is not a measurable property. I might call them lazy, but you might think that they are just waiting for something tasty to walk by. Lazy is an opinion, and is not scientifically testable.

These flowers are so long and thin that only hummingbirds can get to the nectar. What would be the advantage of only letting certain creatures get the nectar?
- 
It makes it more likely that the flower will be pollinated.Yes! As you can see in the Flowers video, the flower needs a pollinator to carry its pollen to another flower of the same kind. If only hummingbirds can get to the nectar, they are more likely to visit other flowers of the same kind. By doing that, they carry pollen from one flower to another, pollenating them. That makes this a strong advantage for the plant.
- 
It keeps animals from eating the nectar.No. The nectar is supposed to be eaten. It serves as a treat to get animals to come to the flower.
- 
It helps the hummingbirds get more food.No. While getting more food would be an advantage for the hummingbirds, it would not help the plant.
- 
There is no advantage.No. Flowers have specific shapes, colors, and smells for a reason.
