Reflection of Science Night

ICE ICE BABY

Last Thursday afternoon , I attended Los Medanos Elementary's Math and Science night with the rest of my classmates. From the  many interesting topics we found  for the booth, we chose to make ice cream utilizing simple house-hold materials including milk, sea salt, ice, sugar, and vanilla extract. My role in this project was actually doing a bit of everything; from buying some of the materials to helping make the actual ice cream solution, coming up with our name, having the music playing in the background,  and even interacting with the kids themselves by showing them how to turn it into actual ice cream and  teaching them the science behind it.

From this experience, I believe I learned how people tend to behave, especially children ,who for the most part are very influenced  by others. For example, by hearing or watching other kids around them  go to a specific booth, they decided to follow as well. I also gained the ability to interact with strangers, show them new things in the process. My organization and planning skills were also definitely put into practice, as together as a group we gathered up all the supplies and planned out how everything would turn out.

If I were to provide any advice for those next year who would like to make their own ice cream booth, I would definitely recommend not underestimating your supplies, especially the salt and ice required. If so, bring double what you think you would need, just in case. It would also be helpful to make all of your ice cream solutions beforehand so as not to be rushing or worrying hallway through that you ran out or there is too many kids at once waiting.  An ice bucket would probably also come in handy.

Overall, I believe it was a success even if we may have ran out of salt in the end and it was getting harder to turn it into actual ice cream. A lot of the children had never actually made ice cream so it was a very nice experience for a large majority of them. Everyone was very cooperative and open-minded; making it all exciting by smiling, jumping, and asking numerous questions. Both parents and the children, themselves were very shocked and interested in the ingredients utilized and the  process they underwent.

P.S. the struggle was real.

H-Weezy Problem

Population Size: 1000

Step 1 : q²=.01     Homozygous recessive individual   Step 2:  q=0.1      Homozygous recessive allele          

    Step 3:  p=0.9   homozygous dominant    allele                                                           
    Step 4: p²=0.81   homozygous dominant                                       individual
    Step 5: 2pq= 2(0.9)(0.1)=.18  heterozygous                                                 individual     
    Step 6:  .18(1000)=180 
                 180 heterozygous individuals
    Step 7:  .01(1000)=10   
                 10 homozygous recessive individuals
    Step 8:  .81(1000)=810
                 810 homozygous dominant individuals

Solutions

      Although it was difficult to distinguish the substances because the data for each solution was all over the place , I found that solution A was the stimulator , solution B was the depressant , and solution C was the water. I determined this by counting how many 30's and 40's were found in each category because they seemed to be recorded the most. The numbers were close but they showed a clear difference . Solution A had twenty seven 30's and twenty two 40's while solution B had twenty one 30's and fourteen 40's . Solution C had twenty two 30's and eighteen 40's.  Thus supporting the inference that A has the highest number of heartbeats, B has the least number , and C is in between.

My Three Favorite Ecology Pictures

#33:Flowers
This  was taken in the beautiful campus of UC Berkeley. In this particular picture I was actually attempting to capture a photo of  a bee or a butterfly  feeding on the nectar of these flowers . However, I wasn't able to keep up with their pace and found myself  looking and sounding a bit crazy in front of the several Berkeley students walking past my friends and I. Oops. lol.

 

 #30:Primary Consumer

In this picture I was roaming the more nature-like part of Buchanan Park and I found these two bunnies: the brown one in the top left corner and the black one in the center. To my surprise and benefit they didn't run away and I was able to take a close-up of them with a peace sign of course.

 

 

 

#36: Bird

I enjoyed taking this particular picture because I noticed the small ducklings resting under the sun alongside their mother. They were adorable and I loved observing them as they waddled around for what seemed like forever. This was taken at Buchanan.
