Ok, thanks. I listened to what you guys said and I tried to improve it :/.
| Quote: | Acids
Acids, is a substance that has the power to change colors,
react in many different ways, and can even harm the human body. My
science fair topic is acids because acids can have many different
reactions, there are a variety of different acids, one thing might not mean
the other, and this interests me. Some of the subtopics that I researched
was the reactivity of acids, neutralization reactions, strong vs weak acids,
acid absorbency, and hard and soft acids and bases.
Hard and soft acids and bases. Hard acids like to go to hard
bases while the soft acids like to go to the soft bases. This shows how the
acids and bases that are the same type, for example if they were hard
then they would go together while it would be the different if the acid was
hard and the base was soft. The term hard and soft does not mean that
the acids and bases or hard or weak, so the acids are split into 2 groups.
Those 2 groups of acids and bases depends on if the acid or base is hard
and soft, soft and weak, strong, and hard, and weak and strong. “We can
usually recognize hardness or softness in a qualitative way by examining
an acid or base, particularly the donor or acceptor atoms” as found in the
last paragraph of Organic and Biological Chemistry . In other words, you
can find an acid’s or base’s hardness or softness by observing the atoms.
Possible independent and dependent variables could include, the type of
acid as the independent variable, and which acid would be the hardest or
the softest. This relates to the topic because it shows how one thing might
not mean the other because hard might not mean strong and soft may
not mean weak.
Strong and weak acids can be determined by their pH, which is
how acidic or basic something is. The pH is how many hydrogen ions
there are in an acid or the concentration of it, a lower number also means
that there is more ions in that acid. . Strong acids have a pH from 0-4
which is very acidic (note: the lower the pH is the more acidic and the
higher the pH is the more basic), weak acids have a pH that is
somewhere in between 3-6. “A strong acid is one which is virtually 100%
ionised in solution.” found in Strong and Weak Acids. This means that if
the acid is in water or any solution(a liquid, or gases), it will exchange
one or more of its protons and give it to a water molecule that would
make a ion, an ion is an atom/molecule that got or loss a proton or
electron. “Hydrogen chloride is a strong acid” in Strong and Weak Acids.
This is an example of the definition that a strong acid is an acid that gives
protons or electrons away because when hydrogen chloride dissolves in
water (gotten from strong and weak acids at 2nd subtopic and 11th
paragraph or sentence) it splits off and gives its hydrogen and chloride
ions to the solution (water in this case) and ionizes completely. Possible
independent and dependent variables could be the acids, and the
dependent variable could be if it were strong or weak.
Acids have many different reactions and bases. |
Could you guys tell me what you think of it.

The science fair is 35% of my grade for the whole semester. Don't do it and I have a D.

According to your revised work, IMHO it's seems rushed and researching was not put into effort.
Did you gather enough info to do your research paper?
First do a brain storm, which is to do an out line of what you want to write.
Then take a look at the outline and see what you want to change. Once you have idea of what you want to write then start writing your research paper.
It's like building a car, designers and engineers first need to draw a bluepinrt of that car. They need to make changes and adjustments. Once they all got clear picture and a strong idea of what need to be done, then they start on the real thing.
It's the same with your research paper.
An research paper can be as the following:
Introduction: A general intro about acids (not too much info here), topic sentence and 2 to 3 keypoints that will make the reader interested and want to continue reading.
Body: A more detail info about acids and start on your first keypoint
Keypoint#1: Some info about it and then your support evidences (citation)
keypoint#2: info, and support evidences (citation).
keypoitn#3: info, and support evidences (citation).
Conclusion: A reminder to the reader of your topic sentence
and then your conclusion.
Don't end it in "they lived happily ever after" THE END.
Examples of how to do citation:
Support evidence (citation: Title of book, author's name, and page number)
or
Evidence and put a small number next to it
e.g. support evidence1
support evidence2
support evidence3
Then on a own sheet of paper, write down the title of the book, author's name and page number.
The 2nd one is simlar to how wikipedia does it.

| Well if this is only 8th grade, his research paper should be good, right? I've helped grade 9th grade english papers, and those are quite terrible. Teachers don't really expect much out of your writing skills for a while, as long as you include everything, it should be fine.

| Quote: | | Acids and bases are involved in bodily functions, but the body contains buffers that are either weak acids or weak bases. These buffers balance the body, so that organs and tissues aren't damaged. |
Just something I happened to remember.
