1. Our Earth’s atmosphere is made of gases like carbon dioxide, methane, and water vapor.
2. When rays of sunlight are emitted onto the Earth’s surface, the rays are reflected back into space, but our atmosphere keeps the energy (heat) trapped in.
3. The gases in the atmosphere absorb the heat and radiate it back to Earth’s surface.
4.This keeps the Earth warm enough to support life.
5. One of the gases in our Earth’s atmosphere is Carbon Dioxide, which is released when we use fossil fuels (gasoline).
6. This puts more Carbon Dioxide into the Earth and the atmosphere.
7.Over the last 650,000 years, the amount of Carbon Dioxide in our Earth has grown by 30%
8. This means that we are putting more Carbon Dioxide into the Earth when we use gas.
9. This causes the Earth to grow even hotter and almost too hot.
10. Plants consume Carbon Dioxide and release oxygen, but once they are cut, the plants can no longer consume the Carbon Dioxide.

1. Humans using “greenhouse gasses” strongly contribute to global warming
2. Even if humans didn’t use greenhouse gases the Earth’s temperature would still increase by about another degree
3. Scientists predict that, at this rate, the Earth could increase from 2.5 degrees warmer to 10 degrees warmer.
4. The goal, and possible solution, is to regulate the GHG (greenhouse gas) levels
5. The aim is to get the levels down to 450-550 ppm (parts per million) and it is currently at 380 ppm
6. “According to the IPCC, we'd have to reduce GHG emissions by 50% to 80% of what they're on track to be in the next century to reach this level”
7. Scientists are coming up with “Stabilization wedges” which are little things that people can do to cut back and stabilize GHG
8. These wedges consist of things like improvements on energy efficiency, improvements on fuel economy, and increases in wind and solar power
9. “ There is also the potential to capture the carbon dioxide emitted from fossil fuels and store it underground—a process called "carbon sequestration."
10. As well as reducing the amount of gases we put into the atmosphere, we can also cut back on the amount we take from it to help prevent global warming.

Periodic-als Vocabulary
- Group:
The vertical columns on the periodic table. - Periods:
The horizontal rows on the periodic table. - Element:
A substance that can not be decomposed into simpler substances by chemical means. - Compound:
A substance of two or more elements in fixed proportions. Compounds can be decomposed into their constituent elements. - Atomic Number:
Integral number of protons in the nucleus; defines the identity of element. - Atomic Mass:
One twelfth of a mass of an atom of the carbon-12 isotope; a unit used for stating atomic and formula weights; also called dalton. - Atom:
- Ion:
An atom or a group of atoms that carries an electric charge. - Valence Electron:
Outermost electrons of atoms; usually those involved in bonding. - Metal:
An element below and to the left of the stepwise division (metalloids) in the upper right corner of the periodic table; about 80% of the known elements are metals. - Nonmetal:
An element or substance that is not a metal. - Metalloids:
Elements with properties intermediate between metals and nonmetals. - Noble Gas:
Elements of the periodic Group 0; also called rare gases; formerly called inert gases. - Alkali Metal:
Metals of Group IA (Na, K, Rb). - Alkaline Earth Metal:
Group IIA metals. - Halogen:
Group VIIA elements: F, Cl, Br, I. - Cation:
A positive ion; an atom or group of atoms that has lost one or more electrons. - Anion:
A negative ion; an atom or group of atoms that has gained one or more electrons. - Electron Affinity:
The amount of energy absorbed in the process in which an electron is added to a neutral isolated gaseous atom to form a gaseous ion with a 1- charge; has a negative value if energy is released. - A measure of the relative tendency of an atom to attract electrons to itself when chemically combined with another atom. As you move across the periodic table to the right, electronegativity in the elements increase. As you move down a group in the periodic table, the electronegativity decreases.
- Ionization Energy (explain the trend):
The minimum amount of energy required to remove the most loosely held electron of an isolated gaseous atom or ion. Going across the periodic table to the right, ionization energy increases, and going down a group, ionization energy decreases. - Atomic Radii (explain the trend):
Radius of an atom. Going across the periodic table to the right, the atomic radius decreases and, going down a group, the atomic radius increases. - Density:
Mass per unit Volume: D=MV - Melting Point:

"Mercury." - Element Information, Properties and Uses. N.p., n.d. Web. 16 Sept. 2014
History Facts
Mercury was well know to the Greeks, Romans, Chinese and Hindus. The Romans used mercury mines as penal institutions (jails) for criminals and undesirables. These prisoners would work in the mines as punishment. The prison guards realized that the prisoners would become poisoned so they would not have to execute them publicly. (Weird mercury history) Sometime in the 1830's when felt hats were first being produced, they used to make them out of camel fur. The workmen that made the hats realized that the felting process was sped up if the material was doused in camel urine. Needless to say, the workmen began to use their own urine, but one worker seemed to produce superior felt. It turns out that that man was being treated for syphilis with a mercury treatment, and his pee was making the felt on the hats nicer.
Uses Facts
Mercury was used in making hats, treatment of STD's, thermometers, and street lamps.
Properties Facts
- Melting point -38.83 °C- Boiling point 356.7 °C
- Can change forms in nature
- Is a liquid at room temperature

Scientist Interview Questions and Research
1. What got you interested in the field of chemistry?
Wanted to follow in his father's footsteps and become a science teacher, and then attended an international chemistry conference which sparked his idea for the periodic table.
2. What significant contributions did you make to science?
Discovered periodic law and created the periodic table. After attending the first ever international chemistry conference, it sparked the idea for the periodic table. He was planning on organizing the table by weight, and the conference was about how to determine the weight of the elements. Wrote an advanced, 500 page chemistry textbook that put him at the forefront of Russian chemical education. Later, he wrote another chemistry textbook that was written in several languages.
3. Did you discover or invent anything notable? If so, what?
Discovered periodic law and invented the periodic table. Using his knowledge, he could predict existence and properties of new chemical elements.
4. Where did you study? Was your major in science?
He studied to be a teacher at Saint Petersburg’s Main Pedalogical Institute, where his father studied and graduated. He went back to get a masters in chemistry and was awarded his degree in 1856.
6. What were your goals and aspirations as a scientist?
To create an easier, more understandable way to describe chemistry and the elements to an "average Joe". He wanted to do this by finding more fundamental principles to add to his table.
7. Was chemistry accepted as a science in your time period/ country (Russian province of Siberia)?
Mendeleev felt that Germany was more advanced in their chemical research than Russia at the time (1860's). It was somewhat accepted, but was pretty much just a bunch of random information and patchwork.
8. What did you do for a living?
He was a science teacher, until he got an award to go to western Europe to persue chemical research, and then went back to being a teacher again.
9. What did people think of you?
He was loved by his students and peers and had been described as a charismatic teacher and lecturer.
10. What gave you the idea for your invention?
After attending a chemistry conference, he knew he wanted to organize chemistry so that people could understand it. Also the conference pretty much told him everything he needed to know to create his table.
