Science Night

Reflections of Service Learning Experience
As the night began, I realized how important it was to help out our community. As the administrators of the school began letting their elementary students and families start entering, I saw so many kids coming and gathering around everywhere. We had plenty of kids. My role was to put water into cups and cornstarch into ziplog bags when running out. But their were so many kids that I had to eventually help my partners Jackie and Diana. So I had to leave my role apart and start teaching the children how to make OOBLECK. Their were so many kids, we were putting in work everytime students would come. I had to help them because of the children were just standing around waiting for Diana or Jackie to help them they would of gotten bored and left. During our experiment, I was able to observe the little children and the parents. I was determining that the children were getting excited in the way that they would mix the cornstarch and water so aggressively, they would sometimes come again for a second try. The parents seem happy that their children were learning concepts and ideas of constructing things on their own. The parents would also explain to them how to do it after we were done instructing them. My partners reactions seem very stressful because we would run out of supplies and materials so we had to kinda stop and make the children wait like 5 seconds. The families and the children were having plenty of fun making OOBLECK, they were surprised that they can make oobleck with house keep materials. After this experience, I gained that all children are the same, they view/see things and think differently. I personally have 3 younger sisters that are approximately the same age as the children. I am kinda rude to my sisters just like every other brother and sister. That's the kinda of love we tend to show our siblings. I learned how to be more pollite to children even though it can be very frustrating. So I feel like I gained an experience to be more understandable with children and that my sisters deserve the kindness of me more than anyone. Lastly, their was this one old lady that came to our table asking how to make Oobleck. She wanted to make some but Diana couldn't understand her so Diana just gave her some in a ziplog bag but I feel like the old lady wanted to make some because she didn't have the opportunity to go through this when she was younger, I feel like she wished she had the opportunity to.

Hardy-Weinberg

                                           Problem Solver

                                        For my problem, the q2 that was given to me was .06. 

Now the steps I went through to solve my problem were: 

1. I had been given .06 as my q2, therefore I was able to find q. 
2. Once I found q I decided to use the formula 1-q=p to find p. 
3. When I reached to find p I then of course squared it to find p2. 
4. After I had found what the variables for p & q were I was able to find the heterozygous which is  2xpxq. 
5. After all that identification, I was able to contain the number of individuals by multiplying the homozygous recessive individual (q2), homozygous dominant individual (p2), and the heterozygous individual (2pq) by 1000 because that was the population.
6. I then looked at the results of number of of allies each factor had in terms of percentage.  

That is how I solved the problem, so therefore these were me calculations or results...

***Remember I was given p2 as .06 and theirs 1000 individuals in a population.

             q2= .06

             q= .245                   (1-q=p)

             p= .755.                   1-.245=.755=P

             p2= .5700.        

             2pq= .36995

      

                                                                   # of individuals:

                                                q2- 1000(.06)= 60 homo. recessive individuals

                                                p2- 1000(.5700)= 570.0 homo. dominant individual

                                                2pq- 1000(.36995)= 369.95 as 370 heterozygous individuals

     

                                                             60+570+370= 1000 individuals in population. 

                                                                       # of alleles:

                                                     24.5% of the alleles are recessive

                                                     75.5% of the alleles are dominant

                                                     6% of the alleles are homozygous recessive 

                                                     57% of the alleles are homozygous dominant 

                                                     37% of the alleles are heterozygous 

                

California Black Worm

          Throughout this experiment with the Black Worms, we all concluded 3 different solutions as A, B, or C. We in groups identified their heartbeats per minute. Anyway, I personally refer that substance C is stimulant because it has high numbers in all groups. According to the data, substance B averages out to be in the 35-40 beats per minute within all groups. In perspectives of google with information of worms, it stated that their normal pulse rate is 15 per 30 seconds. So with that said, 30 pulses had to be in one minute. 30 pulses is their normal rate per minute. Substance B is the normal solution because it is the closest to 30 pulses. Solutions B averages out to 25-30 beats per minute. Now substance A is depressant since it manages out to be an average of 45-50 pulses per minute within all the groups. The method I used was calculating them all and finding their averages for each three substances. I added them all and then divided by the numbers I used which is called the mean.

Ecology Selfies

As you can see on the first picture, I am touching an apple full of eagerness, while taking the "selfie" I was not calmed at all because most of all the pictures I assumed to take came out pretty horrible. I was such in a hurry to just finally eat the fresh apple, THE FRUIT. Long story short, my mom buys lots of apples and she always ends up throwing them away because they get rotten cause no one at the house eats them or pays attention to them. But now that I gathered an apple into my finger tips it turned out to be delicious. 

Now the second picture is just a random feather I found outside my house. I don't know from what type of bird it is but all I know is that it's a feather, a beautiful one too.  This feather was pretty long, I had to cut some of it off since it wouldn't had fit in my selfie but over all it was a decent feather detached from a bird to randomly find on the floor. #excusemyuglyface

Oh my god I look so pale but finally this third picture is a flower or plant whatever it is, is part of my mom's flower/plants collection. I assume that flowers and plants are both the same thing. Anyway, it was to dark and late to go outside and take a pic so I found this plant inside the hall pathway and decided to just take a picture of this flower, it's so green and huge. It seems like it's so healthy. My mom for sure takes care of her plants.
