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.

I want to test a new fertilizer, to find the best concentration for my garden. To do this, I plan to divide my garden into four sections.
Section A. I will use 5 grams of fertilizer per gallon each time I fertilize.
Section B. I will use 10 grams of fertilizer per gallon each time I fertilize.
Section C. I will use 15 grams of fertilizer per gallon each time I fertilize.
For section D, how much fertilizer per gallon should I use?
-
20 grams of fertilizer per gallon.
No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer. -
30 grams of fertilizer per gallon.
No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer. -
1 gram of fertilizer per gallon.
No. This would be a good thing to test, but for this to be a proper science experiment, it is not the correct answer. -
No fertilizer at all.
Yes. For this type of experiment, you need to have a control group. That is a group of test subjects that you do not do anything to. If the control group with no fertilizer grows just as well as the other groups, then I would know that the fertilizer was not working.

This is a photograph of the Painted Desert in Arizona. These layers of rock have not been folded or overturned, so we know that the layer on the bottom is the oldest. This is based on:
-
The Law of Superposition
Yes! The Law of Superposition tells us that unless the layers have been disturbed, they will be in order of their age, with the youngest on the top, and the oldest on the bottom. -
The Law of Crosscutting
No. The Law of Crosscutting tells us that a feature (crack, fault, igneous intrusion, etc.) that cuts through a layer of rock is younger than the layer it cuts through. That makes sense, because the layer would have to be there first, before it could be broken by a fault, etc. -
The Law of Relativity
No. There is a theory of relativity, which deals with the basics of physics, not geology. There is no Law of Relativity. -
The Law of Thermodynamics
No. The Law of Thermodynamics deals with energy, not with layers of rock.

The rattle on a Rattlesnake is an adaptation that:
-
attracts a mate.
No. Snakes do not hear airborne sounds, so another snake would not hear the rattle. -
attracts mice and other prey animals.
No. Like other animals, mice would be frightened away by the rattle. -
warns predators to stay away.
Yes! The sound of a Rattlesnake's rattle is a warning that the snake will bite to defend itself. -
helps the snake hide.
No. There is nothing about the rattle that would serve as camouflage or help the snake hide.

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.
