What were the contributions of each of these scientists to the discovery of the atom?
a. Dalton
Dalton’s contribution to the scienticfic world was creating the Atomic
Theory. The atomic theory explains that, “ Elements are made of extremely
small particles called atoms. Atoms of a given element are identical in
size, mass and other properties; atoms of different elements differ in
size, mass and other properties. Atoms cannot be subdivided, created
or destroyed.” Therefore, all matter is made of atoms, atoms are
indestructible, all atoms in an element are identical in mass and
properties, compounds are formed by a combination of two or more
kinds of atoms and a chemical reaction is a rearrangement of
atoms.This theory explains the attributes of atoms, such as the things
that are identical and the different properties. Dalton’s theory helped
scientists to figure out how atoms work and how chemical reactions
happen.
b. Thomson - V ideo
Thomson’s contribution to the scientific world was that he helped
to develop the Atomic Theory by discovering the electrons. In 1897,
Thomson discovered the electron by experimenting with a Crookes, or a
cathode ray, tube. Thomson then realized that the accepted model of
an atom did not include negative or positive charged particles. He then
decided to use plum pudding as a model or example. He had used the
pudding to represent the atom and the raisins were the positive ions.
Thomson's model of the atom did explain some of the electrical
properties of the atom due to the electrons but not all we need to know
about the atom.
c. Rutherford
Ernest Rutherford, a former student of Thomson, proved
Thomson's plum pudding model to be wrong. Rutherford did a
series of experiments using particles. These experiments were
performed when Rutherford aimed particles at solid things such
as foil. Rutherford soon found out that although most of the alpha
particles passed unaffected through the foil, a small number of
particles were deflected by the foil, and a few came straight back.
Rutherford then concluded that the atom consisted of a small and
dense positively charged nucleus in the center of the atom with
negatively charged electrons surrounding it. The discovery of the
nucleus became what Rutherford was known for.
D. Bohr
In 1913 Bohr proposed his shell model of the atom to explain
how electrons can have orbits around the nucleus. The motion of
the electrons in the Rutherford model was unstable because, any
charged particle moving on a curved path releases radiation; thus,
the electrons would lose energy. To fix the stable atom problem,
Bohr modified the Rutherford model by requiring that the electrons
move in orbits of a specific size and energy. The energy of an
electron depends on the size of the orbit and is lower for smaller orbits. The atom will be
completely stable in the state with the smallest orbit.
3. Structure of the Atom
Video
Video2
a. Nucleus, protons, neutrons, electrons
Atoms are made of extremely tiny particles called
protons, neutrons, and electrons. Protons and neutrons are
in the center of the atom, making up the nucleus. The
charge of the proton and electron are opposite charges.
Since opposite charges attract, protons and electrons
attract each other. Electrons are the particles orbiting the nucleus. This contributes to the
atomic number of the atom and helps to balance the atom. The electrons have no
charge.
b. Atomic Mass
Atomic Mass is the mass of an atom of a
chemical element expressed in amu (atomic mass
units). It is also the same number as the number of
protons and neutrons in the atom or to the average
number allowing for abundance of different
isotopes.
c. Charge
The electron always has a negative charge. The
proton always has a positive charge. If the charge of an
entire atom is zero, or neutral, there are equal numbers of
positive and negative charges. Neutral atoms have
equal numbers of both electrons and protons.
d. Valence Electrons
A valence electron is an outer orbit of electron
that is associated with an atom, and that can participate
in chemical bonds. In a single covalent bond, both
atoms in the bonds contribute one valence electron in
order to form a shared pair.

4. Isotopes

a. Provide Examples (screenshots from simulation)
b. How are isotopes used to find the age of fossils?
Relative dating is used to determine a fossils
approximate age by comparing it to similar rocks and
fossils of known ages. Absolute dating is used to
determine an age of a fossil by using radiometric dating
to measure the decay of it’s isotopes, either within the
fossil or more often the rocks that are near it or around
it.
5. Families of the Periodic Table
*Describe the life of Mendeleev and how he created the Periodic Table.
Dmitry Ivanovich Mendeleyev, born January 27 , 1834, in Tobolsk, Siberia,
Russian Empire. He was a Russian chemist who developed the periodic classification of
the elements. Mendeleev found that, when all the known chemical elements were
arranged in order of increasing atomic weight, the resulting table displayed a reocurring
pattern of properties within groups of elements. In his version of the periodic table of
1871, he left gaps in places where he believed unknown elements would find their place.
He later died January 20, 1907.
*What makes the elements the similar in each family?
a. Alkali Metals
The alkali metals, found in group 1 of the periodic table (formerly known as group IA),
are very reactive metals that do not occur freely in nature. These metals have only one electron
in their outer shell.
b. Alkaline Earth Metals
The members of the alkaline earth metals include: beryllium, magnesium, calcium,
strontium, barium and radium. While not as reactive as the alkali metals, this family knows how
to make bonds very easily. Each of them has two electrons in their outer shell.
c. Halogens
Group 17 of the periodic table of elements (halogens) , including fluorine, chlorine,
bromine, iodine, and astatine. The halogens are diatomic and tend to form salts.
d. Noble Gases
The noble gases are the chemical elements in group 18 of the periodic table. They are
the most stable due to having the maximum number of valence electrons their outer shell can
hold. This colunm contains helium, neon, argon, krypton, xenon, and radon.
6. Choose an article to read from site and summarize:
https://www.livescience.com/37206-atom-definition.html
This article explains how the nucleus, protons, nuetrons and electrons. The article that
was interesting to me was the article about the nucleus. It was discovered in 1911 by Ernest
Rutherford. James Chadwick, a British physicist and student of Rutherford, was able to confirm
this discovery in 1932. All the mass of the atom is in the nucleus. The protons and neutrons
that make up the nucleus are approximately the same mass. The nucleus is also held together
by the "strong force.” This force between the protons and neutrons overcomes the repulsive
electrical force that would, according to the rules of electricity, push the protons apart otherwise.
Some atomic nucleus` are unstable because the binding force varies for different atoms based
on the size of the nucleus. These atoms will then decay into other elements, such as carbon-14
decaying into nitrogen-14.
7. What are some trends in the periodic table as you move from left to right and top to bottom?
Use evidence (graphs) from the graphing activity.
In our science class, we have been learning about atomic structure. In this unit, we learned that
the atomic structure is made up by atomic radius and ionization energy.
Atomic Radius is when there is a one-half distance between the nucleus of identical atoms that
are bonded together. Ionization energy is energy required to remove an electron from a atom or
ion. These two are similar because, as the ionization energy increases, the atomic radius
decreases and this is also the case when you move left and right or up and down on the
periodic table.
An example of this could be Lithium and Fluorine. These two elements are both located on the
second horizontal line on the periodic table. Another example that can be used is Sodium and
Argon. Bother these elements are located on the third horizontal line on the periodic table.
Previously mentioned, when the ionization energy increases, the atomic radius decreases and
this is the case when moving left to right on the periodic table. There are also horizontal lines
called periods on the periodic table. These lines consist of elements which share no chemical
properties and they are not similar
An example that can be used is Lithium and Sodium. Lithium and sodium are located with the
alkali metals on the periodic table. Another example that can be used is magnesium and
calcium and these two elements are located with the alkaline earth metals on the periodic table.
The periodic table consists of 4 families. Some examples of periodic table families are the alkali
metals and these metals have a positive charge of one. Another example, is the alkaline earth
metals and these metals have a positive charge of two. Halogens have a negative charge of 2
and noble gases have a negative charge of one. As stated in the previous paragraphs, these
two are similar, so as ionization energy increases, atomic radius decreases and this is also the
case when you move down the periodic table.

The purpose of this experiment was to see how fast a car would go when put on a ramp.
My hyposthesis for this experiment was that the higher the ramp, the faster the car would
accelerate in speed. A ring stand had been set up at our table and we had rested the ramp on it.
Each time we had tested the car for it’s velocity, time and distance, we had recorded this data.
This data would later go into a graph. After multiple attempt we sat down and started doing the
math to find the velocity and accelerations. Once we had finished that we put the information
into the graph. During the first attempt, the ramp was 125 meters on the opposing side. The total
distance was 600 m and the first distance was half of the ramp and this was about 12 seconds.
The velocity later turned out to be 50 m/sec. This data had caused the acceleration of the 125
meter tall ramp to be about 1.45 ,eters per second. When we testeed the second distance, the car
had traveled the whole entire length of the ramp. The distance was still 600 m and the time was 9
seconds. Therefore, the velocity was 66.66 m/sec. To futher back up out hypothesis with data, we
then tested a different height, 250 m on the opposing side. The distance had stayed the same at
600 m. but the time had totaled up to about 8 seconds. This caused the velocity to be about 75
m/sec. Next, we had tested the second distance which was the length of the entire ramp. The time
had came out to be approximately 2 seconds and the velocity was about 300 m/sec. The
accelerataion came out to being about 112.5 meters per second. In conclusion, our hypothesis,
which stated that the higher the ramp, the faster the car would accelerate in speed, had been
proven to be true with this experiment.

My dream was interrupted by the sound of my bus passing by and the sound of my
alarm ringing. About 15 minutes later I rubbed my eyes and stared at my phone it read, “7:59.” I
jumped out of bed and quickly got ready for school. My mom heard all the noise coming from
my room and got up knowing that she was going to have to drive me to school for the 30th time
this year. I grabbed my breakfast and waited in the car for my mom. I reached school and got a
pass and raced to my locker before 2nd period started. Soon my water bottle goes dry and I
asked to fill it up at the water fountain. The water fountain was 6 meters away from Mr. Lopez’s
room and it took me 25 seconds to fill up the water bottle and get back to the classroom. Soon
the class was over and I was heading to Mr. Fusari's room which was 36 meters away. It took
about 12 seconds for me to get there and then it took me 20 seconds to realize that I had
forgotten my binder in my locker. I bridgewalked 8 meter for approximately 34 seconds from Mr.
Fusari's room to the beginning of the stairs and then got tired of that. It took me about 2 seconds
to get from a bridge walk to standing up. I decided to run back to my locker that was 25 meters
away from where I was standing. It took me about 8 seconds to get to my locker and about 20
seconds to open it. After frantically searching for my binder I was shocked that my binder wasn’t
in my locker. I quickly remembered that I had left my binder in Ms. Poeltl room the previous day
during homeroom. I decided that I didn’t want to go back to class so I footdanced my way to Ms.
Poeltl room and retrieved my binder. The distance was about 14 meters that had taken 18
seconds to get there and it took you 15 seconds to quickly retrieve your binder. Finally you head
to back to Social Studies and continue your very interesting day.

Story:
My dream was interrupted by the sound of my bus passing by and the sound of my
alarm ringing. About 15 minutes later I rubbed my eyes and stared at my phone it read, “7:59.” I
jumped out of bed and quickly got ready for school. My mom heard all the noise coming from
my room and got up knowing that she was going to have to drive me to school for the 30th time
this year. I grabbed my breakfast and waited in the car for my mom. I reached school and got
apass and raced to my locker before 2nd period starts. Soon my water bottle goes dry and I

Hypothesis: Angle vs. Mechanical Advantage or Angle vs. Efficiency (Use if...then…)
A. Ideal Mechanical Advantage
If there is a higher angle, there will be a higher ideal mechanical advantage.
B. Actual Mechanical Advantage
If there is a higher angle, there will be a higher mechanical advantage.
C. Efficiency
If there is a lower angle, there will be a higher efficiency.
*Think about the scientific Method

65 1.1 1.95 85%
***Why is the Actual Mechanical Advantage always less than the Ideal Mechanical
It will always be less than because the IMA is the ideal that people want to use for
the inclined planes. AMA is what the numbers actually are, so it will be less than
the ideal.

Conclusion:
*Write your OWN CONCLUSION HERE! Use Data
My hypothesis is that if there is a bigger angle, then there is a higher mechanical
advantage. In our experiment, I had to use the angle to find things like the efficiency, IMA, and
AMA. To prove my hypothesis, I provided some data that I found in my experiment. First, I had
an angle of 4 degrees. The AMA of it was 1.16. Then, we looked at a bigger angle, which was
44 degrees. The AMA of it was 1.53.This shows that the larger the angle, the larger mechanical
advantage.

October Sky Research
Videos Playlist
Research the following questions related to the movie, “October Sky”:
1. Who was Wernher Von Braun? What were his contributions to rocketry?
He was the aerospace engineer and space architect for NASA.
2. Why is there a large amount of coal in West Virginia? Where did coal come from?
There was a large amount of coal in West Virginia because of the many . Coal comes from
many plants over time making layers and layers of dead plants which then end up turning into
coal after all the pressure.
3. How is coal different from oil?
Coal can be mined (solid) while oil is drilled from the ground (liquid)
4. How is coal used to produce electricity?
Coal is used to produce energy from first starting out as a thermal energy and then the steam
from that is then use to power a generator which then produces energy.
5. How is coal an example of Chemical Potential Energy?
The coal is made from dead plants therefore it is a form of chemical potential energy. The living
creatures that it was before, stored energy therefore when it is burned the energy is let out.
6. What are the dangers of working in a coal mine?
There are many dangers including getting crushed by falling rocks and breathing in dangerous
fumes including coal dust.
7. Why did coal miners carry canaries into the mine?
The canaries show signs of distress when there were toxic gases like methane or monoxide.
8. How does coal contribute to Global warming? Explain using a diagram.
The more coal we burn the more it affects the ozone layer. Like burning gas wears down the
ozone layer, so does burning coal.
9. Is there technology to make coal “clean”? How does it work?
It’s a machine to lessen the impacts of coal on the environment. It captures the carbon while
being burned so therefore the ozone layer is not constantly wearing down.

I found the equations hard to memorize because there were so many of them.
3. Provide an example of 3 types of graphs that were used this year in science? Why did
it make sense to use these graphs for those activities?
The pie graph was used when you wanted to show how was in a specific atom (in percents).
The line graph was used when the temperature of the water increased and or decreased.
The bar graph was used to show the numbers of specific things like heat energy and
substance.
4. What were the key tips you remembered about solving math problems in science this
year? Word problems? Provide an example from this portfolio of a science math
problem that was challenging to solve this year.
I remembered to always remember the units and the formulas because those could
cost you your grade.
5. Which lab conclusion or sample of writing are you most proud of in this portfolio?
The purpose of this experiment was to see how fast a car would go when put on a
ramp. My hyposthesis for this experiment was that the higher the ramp, the faster the
car would accelerate in speed. A ring stand had been set up at our table and we had
rested the ramp on it. Each time we had tested the car for it’s velocity, time and
distance, we had recorded this data. This data would later go into a graph. After
multiple attempt we sat down and started doing the math to find the velocity and
accelerations. Once we had finished that we put the information into the graph. During
the first attempt, the ramp was 125 meters on the opposing side. The total distance was
600 m and the first distance was half of the ramp and this was about 12 seconds. The
velocity later turned out to be 50 m/sec. This data had caused the acceleration of the
125 meter tall ramp to be about 1.45 ,meters per second. When we testeed the second
distance, the car had traveled the whole entire length of the ramp. The distance was
still 600 m and the time was 9 seconds. Therefore, the velocity was 66.66 m/sec. To
futher back up out hypothesis with data, we then tested a different height, 250 m on the
opposing side. The distance had stayed the same at 600 m. but the time had totaled up
to about 8 seconds. This caused the velocity to be about 75 m/sec. Next, we had tested
the second distance which was the length of the entire ramp. The time had came out to
be approximately 2 seconds and the velocity was about 300 m/sec. The accelerataion
came out to being about 112.5 meters per second. In conclusion, our hypothesis, which
stated that the higher the ramp, the faster the car would accelerate in speed, had been
proven to be true with this experiment.
I was proud of this because I had used both numbers and units to describe the
outcome of this experiment and how we did the experiment.
6. What are you excited to learn about in science next year? Do you want to pursue a
