My Reflection on NHD

This year for my NHD project I did a documentary with Daivon Jackson on Evolution vs. Intelligent Design. Although it was a little easier this year than last, we still had small problems to overcome while completing our project. Some of the things that we had to overcome was that we could not find many pictures relating to the theme of evolution. We had to use some of the same pictures of evolution over again, which I believe took away from our project. Although that minor issue occurred we still had many other good qualities in our project. Some of those qualities consisted of having good documents and representation of what we were talking about. Every project has its ups and its down, overall I think that we had more ups then downs. We worked very well which I think helped us out a lot in the end. Although we did not make it to the end, I think that our project was really good and showed growth from last years projects. Who knows third times a charm. Better luck next year.

Native Son chapter 4 "I Dare You!"

English

Chapter 4 pgs. 36-41
Title: I Dare You!


In this chapter, Bigger and all the rest of his gang are waiting for Gus to get back at the pool hall, so that they can go rob the store. Bigger does not want to go and rob the store, because a white man owns it. So without letting his friends know that he is scared to go, he tortures Gus, once Gus arrives at the pool hall. Bigger realizes that Gus was made it back in time enough for them to rob the store, so he makes it seem like Gus was late, by putting a knife down his shirt and making him lick it as well as many other horrible and degrading things. Once Bigger is done torturing Gus, Gus throws a pool ball and hits Bigger in his head. Bigger then tries to hit Gus back but everyone holds him back to stop him from killing Gus. Doc, the pool hall owner starts to laugh at Bigger, which makes Bigger really mad. Bigger then takes his rage out on the pool table by cutting it up with his knife. Doc then pulled out his gun and told Bigger that if he did not get out, he would shoot him. Bigger told Doc “I Dare You!”





I think that Richard Wright was trying to show how big and bad someone may be on the outside doesn’t mean that they are feeling the same way on the inside. Bigger put on this big front for everyone, but when he was alone we got to see how he really felt, which was scared and less than a man.

My Science Project Summary

My Science project was an easy but difficult task. The easy part to me, was the experiment. On the other hand the hard part, was making my project look and seem as if it was a high school project. To make it look and seem more grown up, I had to find out information on enzymes in laundry detergents. The hard part about that, was the fact that I couldn't find any information on specific enzymes in a specific laundry detergent. In order to get this in formation, I had to find out why enzymes were important in all laundry detergents. Overall the project wound up being to me a success, and I enjoyed doing it.

Which Laundry Detergent Will Work Best On Stains?

Question or Problem

Which stain will work better on the stains?


Hypothesis

My hypothesis is that the Extra detergent will work the best on getting the satins out of the clothing.


Material List

Shirt
Markers
Ketchup
Mustard
Grass
Extra Detergent
All Detergent
Dynamo Detergent
Water
Scrubbing Item


Procedure

Step1: Lay the shirt out straight
Step 2: Take one of the stains ex. Ketchup
Step 3: Take one of the detergents and put just enough to cover the entire stain.
Step 4: Take you item that you are using to scrub the stains and scrub the stain (When scrubbing the stain, make sure you add pressure to it. Each time that you scrub any of the stains, make sure you add the same amount of pressure each and every time.)
Step 5: While you are scrubbing the stain, add enough water so that it covers the stain.
Step 6: Once you add the water, continue to scrub the stain for 3 more minutes.
Step 7: Once you have completed this record your results.
Step 8: Label the stain and the detergent that you used with a marker that way you won’t loose your place.
Step 9: Repeat all of the above steps until every stain and detergent is used three times, once per stain.




Data Table


Data Table did not show up correctly, but everything else is here.


Results/Observation


In this experiment, I observed that the grass was the hardest stain to remove. The ketchup and the mustard was very hard as well but they most likely had different results in and every time used a different detergent. The Dynamo detergent did the least amount of work removing the stain form the clothing. I also observed that the Extra and the All detergent worked almost the same.


Conclusion

My hypothesis was in correct. I stated that the Extra detergent would work the best and, when doing the project, event though they had similar results, the All detergent worked out the best on the stains.

Enzymes








What are enzymes?


They are proteins produced by all living organisms that act as catalysts to speed up chemical reactions that would otherwise occur at a much slower rate or not at all.
Why is this important in a laundry?


The enzymes used in laundry detergents act on materials that make up a variety of stains and soils so that these materials can be washed away more easily. These enzymes are named after the materials they can act upon, for example, proteases break down protein based stains.
