D. Inorganic Chemistry
What is A. Physical Chemistry
This is a measure of not only the amount of but also of the effect of Earth`s Gravitational pull on that matter
What is the Weight of an object
A visual, verbal, or mathematical explanation of how things occur is called a(n)

What is Ozone
At the end of an experiment the scientist forms a conclusion based on what?
What is the Data Obtained (from the experiment)
Macroscopic observations of matter reflect the actions of atoms on a ___________ scale.
What is on a submicroscopic scale
What type of data is obtained from numerical observations that describe how much, how little, how big or how fast something is
What is Quantitative data
The chemical that is made up of chlorine, fluorine, and carbon is called
What is a Chloroflurocarbon (CFC)
What effects might the Ozone hole have on humans and other organisms?
Along the lines of: Ultraviolet Radiation can cause cataracts and skin cancer in humans, lower crop yields in agriculture, and disrupted food chains in nature.
Classify the following three examples as Qualitative or Quantitative:
1. 100 pounds
2. cold
3. Smells like bananas
What is Quantitative, Qualitative and Qualitative
List the 5 steps of the Scientific Method in Order. Do these steps have to be followed in order?
What is Observation, Question, Hypothesis, Experiment, Data collection. These steps do not have to be followed in order.
Explain the relationship between CFC`s and the thinning of the Ozone layer.
Along the lines of: Scientists found that as the Ozone levels decreased a correlating rise in CFC`s was taking place.
Compare the macroscopic world with the submicroscopic world.
Much of the scientific world can be observed on the Macroscopic level (without a microscope). The structure, behavior, and composition of all matter can be described on the submicroscopic level (with microscope).
