I wanted to test different amounts of fertilizer to see which was best for growing grass. I mixed water with different amounts of fertilizer, and then added sodium polyacrylate to change it into a gel. Then I sprinkled the grass seeds on top, and waited for them to grow.
I really need a control group for this experiment. What would I use for a control?
-
Water, fertilizer, and grass seed, without any sodium polyacrylate.
No. For the control, we want to skip the thing we are testing for. We are not testing changes caused by the amount of sodium polyacrylate. -
Water, sodium polyacrylate, and grass seed, without any fertilizer.
Yes! We are testing to see how different amounts of fertilizer change the growth of the grass. The amount of fertilizer is the variable we are testing, so the control group should not have any fertilizer. -
Water, sodium polyacrylate, and fertilizer, without any grass seed.
No. For the control, we want to skip the thing we are testing for. We are not testing changes caused by the amount of grass seed, and we know that no grass will grow if we do not have any seeds. -
Sodium polyacrylate, fertilizer, and grass seed, without any water.
No. For the control, we want to skip the thing we are testing for. We are not testing changes caused by the amount of water.

This is Halite, also known as table salt. It was formed when ancient seas dried up, leaving layers of salt behind. What kind of rock is it?.
-
Igneous
No. Igneous rocks formed from magma or lava. The Halite was not melted, and is not an igneous rock. -
Sedimentary
Yes! Sedimentary rocks are deposited by wind, water, ice, or gravity, and they often contain fossils. Halite was deposited in large layers by water, which means that it is a sedimentary rock. Halite is also a mineral, and is one of the few rocks/minerals that we eat. -
Metamorphic
No. Metamorphic rocks have been changed by heat and pressure from a different kind of rock. It is not metamorphic. -
Halite is not a rock.
No. Halite is a naturally occurring solid that forms large layers in the Earth. Halite is a rock.

What do you have to do to replicate an experiment?
-
You do the same experiment several times.
No. Doing the same experiment several times is repetition, not replication. -
You do the same experiment that someone else did.
Yes. By replicating an experiment exactly, you should get the same results as the original experiment. -
You do an improved version of someone's experiment.
For replication, you do the experiment exactly as the original scientist did, without making any changes. -
You look for errors in someone's experiment.
The purpose of replication is to verify, not to look for errors.

After I rubbed this ballon against my hair, it stuck to the side of my head. Why?
-
The balloon stuck because I don't have enough hair.
No. While much of my hair is gone, I still have enough to do this experiment. -
The balloon stuck because the balloon had the same charge as my hair.
No. Two things with the same electrostatic charge will repel, pushing apart. -
The balloon stuck because the balloon had a different charge from my hair.
Yes. When I rubbed the balloon against my hair, electrons moved from my hair to the balloon. The extra electrons gave the balloon a negative charge, and the missing electrons left my hair with a positive charge. Opposite charges attract, so the balloon stuck to my hair. -
The balloon stuck because my hair was magnetized.
No. Rubbing a balloon against something does not magnetize it. Even if it was magnetized, a magnet would not attract the rubber balloon.
