Project
What is in hair dye and how can it affect YOUR hair?
By:
Jenay Smith, Chanei Moe, Michell’e Long, Jahmilla Muse
Abstract
The purpose of this experiment is to distinguish between the damage caused by three different hair colors. The experiments involved dyeing hair with three different colors and looking at the hair before and after to see if there was any damage. The results show that the blond dye caused more damage on the hair. There was more bleach in the blond hair dye and that is what caused more damage to the hair. These findings led us to believe that the more bleach in your hair dye will cause the most damage to hair.
Question:
Does the difference in the chemistry of hair dyes by color affect hair follicles differently?
Hypothesis:
The difference in the chemistry of hair dyes by color does affect hair follicles differently. The lighter the hair dye the more damage.
Materials:
-3 different hair dye color tubes
1. 92 light beige blonde chardonnay
2. 10 black licorice
3. 630 light golden brown
-3 pre-packaged developer cremes
-3 pairs of latex gloves
-6 spoons
-8 styro-foam bowls
-6 coffee filters
-Water
-Binocular microscope
-Light microscope
-Science goggles
-2 different samples of hair
Procedures:
1. Put on gloves
2. Twist off each applicator tip of the developer cream bottles and remove caps
3. Pierce the colorant tubes
4. Squeeze the each tube contents in the indicated developer bottle and replace caps
5. Place sample 1 hair into 4 Styrofoam bowls
6. Apply each dye color to the separated sample 1 hair
7. Let set for 25 minutes
8. Follow steps 6&7 for sample hair 2
9. Using coffee filters carefully rinse all of the hair dye with warm water
10. Let hair samples dry for 24-48 hours
11. Using both microscopes inspect each of the hair samples1&2 both dyed and un-dyed
12. Record data
DATA TABLE – Hair Dye
Dye Type Sample 1 Sample 2
92 Light beige blonde chardonnay
Very bad damage Very bad damage
10 Black licorice No damage Very little damage
630 Light golden brown Very little damage Damage
Observation
Both sample 1&2 with blonde the damage was very bad; there were more splits on the hair then on the original un-dyed hair. When sample 1 was dyed black there was no damage at all and was basically the same as the un-dyed hair. Sample 2 black dyed hair showed very little damage but was enough to be seen. Sample 1 black had no damage and was the same as the original. Sample 2 golden brown had some damage that was visible. Sample 2 golden brown had very little damage that could be seen with the light microscope.
Conclusion
The hypothesis was correct. The observation shows that the blond hair dye caused the most damage. Brown hair dye caused hair damage but, blond hair dye caused split ends and the hair is weaker. The cause of the damage from lightening hair using hair dye is bleach. Hydrogen peroxide is one of the most common lightening agents (bleaches). The peroxide is used in an alkaline solution, which opens the hair shaft to allow the peroxide to react with the melanin. The bleach reacts with the melanin in hair, removing the color in an irreversible chemical reaction. The bleach oxidizes the melanin molecule. The melanin is still present, but the oxidized molecule is colorless. However, bleached hair tends to have a pale yellow tint. The yellow color is the natural color of keratin, the structural protein in hair. Also, bleach reacts more readily with the dark eumelanin pigment than with the phaeomelanin, so some gold or red residual color may remain after lightening.
During the experiment hair dye could have been mixed together, another substance could of gotten in to the individual hair dye, the hair could have been wet when we looked at it, or we altogether could have not dyed the hair. Those are different ways the experiment could have been altered.

Religion in schools
Michelle Long
Religion in schools
Religion in school in my opinion should not be in school. Now Im not saying that you shouldn't have the you're right of freedom of religion but to have many religions in school these days as we do now we shouldn't just focus on one religion. I think that if you want to teach religion then you should teach all the religions not just one thesis of how we got here than it goes into one religion I don't think its right to do that. So in my opinion we shouldn't teach just one religion, we shouldn't teach any religion.
First I say that we shouldn't teach religion in schools because of the fact that not everyone has the same religion. If they don't have the same religion then I think it would be wrong for them to have to sit in class and for them to hear that there religion there way of life is wrong. That the way they are living their life is the wrong way and to put that in theirs heads at a young age. They will start to begin to question their own religion and question their parents and what they tell them. I think this is one of the biggest problems with public schools and the way they try to put religion and class together.
Second of all I think that if you do want to teach religion in public schools then you should teach every religion then just teaching one and having some kids without the same religion feel left out and have kids mess with them every day for being different or expressing their right to be different. Teaching this in any class is wrong and is showing hate toward every different kind of person and in my opinion it is and will always be wrong.
In conclusion I think teaching something that is basically religion is wrong and will always be wrong. People come over here to get away from just one religion and to be free to live their own lives and be as one nation but how could we do that if we plan out there own life.

What I a doing for NHD
Michell’e Long
I choose The Great Depression for my NHD project because it is interesting to me it makes me want to learn more about that topic. The Great Depression is interesting to me because it has racism, the liberal political alliance of the labor unions and the imbalance between the rich and the poor. In my group there is 4 other people and we have not yet picked what type of project we are going to do
