2. The Scientific Method Question problem 2. Variables
The problem is written in the form of a question.
Ex. Does miracle grow work better than other generic fertilizer brands?
2. Variables
Mv: Manipulated/Independent Variable- What is being changed?
Example: MV: miracle grow
Rv: Responding/Dependent Variable- What is being measured?
Example: RV: growth of rose bush
Cv: Control Variables- all other variables must be controlled
Example: CV: same type of rose bush, Same amount of water, sunlight, ect.

3. Scientific Method cont.
3. Hypothesis
Your hypothesis is an educated guess.
4. Design Experiment
Materials and procedure
5. Observation/Data collection
Record what you see in detail
6. Results/Data Analysis
Brief description of the average results
7.Conclusion
Restate your hypothesis and tell if it was right or wrong. Use data to prove or disprove your hypothesis. Then say things that could have gone wrong in your experiment.

4. Periodic Table of Elements

5. Oxygen Element: Oxygen Atomic #: 8 Atomic Mass: 15.9994
Properties and Characteristics: Oxygen's crystal structure is cubic. Oxygen’s oxidation states are 2,1,-2,-1. Its electro negativity is 3.44.
Uses: Oxygen usage is made up into 4 major categories: metallurgy, rocketry, chemical. You also use oxygen to breath and to fuel a fire.
Hazards: A hazard of oxygen usage is forcing air into a cancer patients lungs. The hazard is that it lets the blood’s carbon dioxide reach levels that render a person unconscious or stop breathing entirely.

6. Hydrogen Element: Hydrogen Atomic #: 1 Atomic mass: 1.00794
Properties and Characteristics: Hydrogen is an order less, colorless, and tasteless gas.
Uses: Hydrogen is used to make : ammonia, methanol, gasoline, heating oil, rocket fuel, fertilizers, glass, refined metals, vitamins, cosmetics, semiconductor circuits, soaps, lubricants, cleaners, and even margarine and peanut butter.
Hazards: Hydrogen is very flammable it must be handled with care. If liquid hydrogen comes in contact with bare skin it will give you a severe freeze burn(freeze burn is similar to frostbite). Hydrogen explodes only when it comes in contact with oxygen.

7. Carbon Element: Carbon Atomic #: 6 Atomic mass: 12.0107
Properties and characteristics: It melting point is degrees Celsius. It boiling point is degrees Celsius
Uses: The amorphous form (coal)is used in power plants, it is also used in the iron industry to make steel. The diamond form is used as jewels and used as a part of cutting tools. The graphite form is a great conductor and is used in pencils and sports equipment. A new type of carbon buckminsterfullerene is used in lasers.
Hazards: carbon monoxide will kill you quickly if gets into your lungs.

8. Nitrogen Element: Nitrogen Atomic #: 7 Atomic Mass: 14.0067
Properties and characteristics: Nitrogen's melting point is -210 degrees Celsius. Nitrogen’s boiling point is degrees Celsius. Nitrogen is colorless, tasteless, odorless and an inert gas.
Use: Nitrogen has many uses like: making light bulbs, explosives, and laughing gas.
Hazards: If liquid Nitrogen touches your skin you will get a “cold burn”. The nitrogen gas in the air will deplete the oxygen levels, making it hard to breathe.

9. Polystyrene Slime Polystyrene Slime: Styrofoam and Acetate
Chemical Formula: polyvinyl alcohol 40.0 grams mixed with 960 grams of water. Which is a 4% solution. Borax in a 4% solution which is about 4 grams of borax dissolved in 96 grams of water. Finally a Styrofoam egg carton or cup.
Characteristics/ Properties: The slime characteristics are: colorful, high density, slimy to the touch.
Uses: Used in coolers to keep food cool or hot. Used in hospitals to take laundry down to wash in a disposable bag.
