Science Night

The Science was one of the most fulfilling community service experience I have had the pleasure of participating in. I pitched in a lot in planning and figuring out the set up. During the Science Night, I was hard at work filling up trays, pouring out buckets, and cleaning up water. I tried to provide a lot of energy during the event. Not only was I putting in work, my group mates were also constantly doing something. It was like a machine with five constantly moving parts. Shawn would refill water while Billy would make boats, and Jonathan showed kids how to race while Ivan rinsed out trays. There was a lot of energy in the station. We would cheer and give kids high fives and they would cheer when they won.

The families seemed to get a lot from the experience. It was a place where children could get excited about science and learn things while having fun. It was a chance for families to bond while doing different activities together. It was a time for parents to relax and know that the community is there for them.

This experience has opened my eyes to a lot of things. I found a work ethic inside me that I never knew existed. This work ethic was driven by my motivation to see people smile and cheer after racing their boats. I gained experience working under pressure. Never in a million years did I ever see myself being able to work while worrying about letting people down, until that night. I found a way to convert my worry about letting my teammates down into motivation to keep going and thinking.

This event was really fun but there are a lot of things to know if you want to succeed at it. The most important thing is preparation. Plan out what materials you need and how you plan on getting those materials. For example, if we did not have Jonathan's bucket, it would have been really hard to replace the water we had. If you want a lot of traffic, location is really important. Always find something to do, if you take a break for one minute then that break will catch up to you later on. One last thing you should do is overstock, especially if you anticipate a lot of participants.

Hweezy Problem

• q² ( Frequency of Homozygous Recessive Individuals)= .05
• p² ( Frequency of Homozygous Dominant Individuals)= .61
• 2pq ( Frequency of Heterozygous Individuals) = .34
• q ( Frequency of Dominant allele)= .22
• p ( Frequency of Recessive allele)= .78
• Number of Homozygous Recessive Individuals in population= 50
• Number of Homozygous Dominant Individuals in population= 610
• Number of Heterozygous Individuals in population= 340

Steps

1. Square root q² to obtain q
2. Subtract q  from 1 to obtain p
3. Square p to obtain p² 
4. Multiply p, q, and 2 to obtain 2pq
5. Multiply q² , 2pq, and p²  to 1000 ( the population) to obtain the number of individuals of each genotype.

Solutions in Worm Lab

Worm Lab Solutions

 In the worm lab, Solution A is the depressant, Solution B is the stimulant, and Solution C is the normal solution. When the 

numbers in each group were averaged, Solution A had the lowest pulse rates. Solution B had the highest pulse rates, and Solution C had the medium pulse rates. To come to this conclusion I averaged the numbers for each group, day, and solution separately. I then looked down at each day for each group and listed the solutions from slowest to fastest. When finished I tallied up the number of times each solution appeared in the 3 categories, slow, medium, and fast. A ended up the majority in slow with 7 appearances, B the majority in fast with 6 appearances, and C the majority in medium with 6 appearances. With this I came up with the to the conclusion that A is the depressant B is the stimulant and C is the normal solution.

 Ecology Selfies

     The Ecology scavenger hunt was a tremendously enjoyable experience. It was tiring, frustrating at times, and sometimes difficult but overall it was fun. The teamwork aspect of looking for things with friends and the occasional competition for items on the list enriched the whole "scavenger hunt." The frustration was present though, especially with living things. However the difficulties just made everything more rewarding when something was accomplished. Speaking of what was accomplished here are three of my favorite ecology selfies.

This group selfie is one of my favorites because it shows off the group of friends I went hiking with for the collection of selfies. It really demonstrates the teamwork aspect of it as we put six minds  together to accomplish a goal. Not only did working in a group improve our work but it also made the experience more enjoyable. Another reason I like this selfie is my face in the selfie just makes me laugh every time.

This picture is also one of my favorites because it shows off our creativity. One of the words we struggled to find a way to photograph was parasitism. Our group was confused and it was sort of just put off. However I had a light bulb moment and thought, " Hey we can probably act it out, she did say be creative." The product of this thought was the picture.

This last selfie showcases what I said before about the difficulty of some pictures making them more rewarding when accomplished. Throughout the hiking trip I've tried, and failed, to take a selfie with a bird numerous times. It was frustrating and I went home that day without that selfie accomplished. Now as fate would have it, weeks later walking around U.C Berkeley, I would have the perfect opportunity to get a selfie with a bird. When I finally took it, the satisfaction I felt could not be described.

    So to summarize the Ecology Selfies were a mix of fun times with friends, frustration, fatigue, and an unrivaled sense of accomplishment.
