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?
-
Igneous
No. Igneous rocks are formed from molten lava or magma, not from sand. -
Sedimentary
Yes! 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. -
Metamorphic
No. 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.

In the Yeast and Sugar video, I added different kinds of sugar to bottles with yeast and warm water. One of the bottles was a control. What should have been in that bottle?
-
Just water
No. With just water, you are removing two variables, the yeast and the sugar. You only want to remove the independent variable.
-
Water and yeast
Yes! A control should be exactly like the others, but without the independent variable (the variable you are changing in the experiment.) In this case, the variable you are changing is the kind of sugar, so the control should have everything except for the sugar. -
Water and sugar
No. The yeast is not the independent variable, so leaving it out would not be correct. -
Water and salt
No. Adding salt would be adding a new variable, which is not correct.

The brown spots on this fern contain spores. How are spores different from seeds?
-
Spores are much smaller, because they do not contain stored food for the young plant.
That is part of the answer. Most seeds contain stored food for the developing plant. Orchid seeds are an exception.. -
Spores are a form of asexual reproduction.
That is part of the answer. Spores contain only the genetic material from the parent plant. -
Spores develop into a different kind of plant from the parent.
This is part of the answer. Ferns have alternation of generations, which means that the spores grow into a plant called a prothallia. The prothallia produces male and female sex cells, which join, and grow into another fern plant. -
All of the above.
Yes! All three of the answers are correct.

When a scientist makes a new discovery, other scientists usually do exactly the same experiment. Why?
-
They want to get part of the credit.
No. While replicating an experiment is very important, the scientists who do it usually don't get much credit for their work unless they discover an error in the original experiment. -
Repetition is part of the scientific process.
No. Repetition is when scientists repeat their own experiment several times, not when other scientists do the same experiment. -
They think they can make changes to improve the experiment.
No. By doing exactly the same experiment, they are not changing anything. Instead, they are replicating the experiment as closely as possible. -
Replication is part of the scientific process.
Yes. By replicating the experiment, other scientists can help verify that the results are accurate. There is always a possibility that there was some unnoticed influence on the original experiment, and replication can help spot that.

When water freezes, it:
-
Condenses
No. Condensation happens when water vapor changes from a gas to a liquid. -
Contracts
No. Water does not take up less space when it freezes. -
Expands
Yes! Unlike most substances, water expands to take up more space when it freezes. -
Gains mass.
No. Changing from one state to another does not cause a change in mass.
