This variable changes in response to what the researcher changes on purpose.
What is the dependent variable?
100
atom with same number of protons but different number of neutrons
What is isotope.
200
The amount of H+ ions in a solution
What is pH?
200
A substance with a pH of 7 is this.
What is neutral?
200
This is the generic term for anything that is dissolved in something else. (i.e. salt or sugar, which is dissolved in water)
What is solute?
200
An educated guess purely based on observations or facts
What is hypothesis?

A microorganism which releases water into its environment to regulate its salinity during osmosis is undergoing a process that is similar to a human being who releases moisture on a hot day. This process that helps keep both the microorganism and the human body fluids in balance is known as —
What is homeostasis?
300
This property of water allows water molecules to stick to other water molecules.
What is cohesion?

Hydrochloride = pH 0.0
Lemon Juice = pH 2.2
Tomato Juice = pH 4.1
Urine = pH 6.0
Distilled Water = pH 7.0
Blood = pH 7.4
Toothpaste = pH 9.9
Ammonia = pH 11.9
Sodium Hydroxide = 14.0

Referring to the information above, the STRONGEST ACID listed is substance is this.
What is hydrochloride?
300
This element is found in all biological molecules because it has 4 outer electrons that can form bonds with other elements
What is carbon?

information you gather during an experiment
What is data?
300
smallest unit of life
the cell

What is electrons, protons, neutrons?
400
A way of knowing
What is science?
400
if you have more OH ions in solution
What is a base
500
Water is called this because many substances can dissolve in water.
What is universal solvent?
500
On the pH scale, where would you expect to find a substance that has a neutral pH?
What is 7?
500
The atomic number gives you
What is the number of protons and neutrons? also know that the number of neutrons is atomic mass- atomic number

Roderick had a new pair of Air Jordans and always seems to mess up his shoes within a few weeks months. He heard of a new product called AirWearRepair, which was supposed to keep your shoes looking brand new for up to 4 months. Given his bad luck with his new kicks, Roderick decided to apply the AirWearRepair to only the right shoe of his new Jordans. He wore the new pair of shoes for one month. At the end of the one month, he compared the two shoes to see if the right shoe with AirWearRepair looked any better than the left shoe without AirWearRepair. In this experiment, which shoe is the control group?
What is the shoe without the AirWearRepair?
(no AirWearRepair)
