UCCLM Youth Receive Awards from the Greater San Diego Science and Engineering Fair

     Not only do UCC churches nurture the souls of our always-exciting and sometimes unpredictable youth, but we support their academic development, honor important life milestones and celebrate their honors.   Read here of the accomplishments of two young people from the United Church of Christ of La Mesa, California.

     Project Abstract:  My hypothesis stated that the dissolved oxygen level would be higher during the day because of the high amount of photosynthesis during that time.  My problem was that I needed to know if there would be a higher dissolved oxygen saturation level at daytime or night.  I planned to solve this problem by taking the dissolved oxygen levels during the day and its level over the night.  I would do about 12 tests to get about 100 numbers.
 

     I tested between December 12th and January 2nd. I went at 5:30 am and at 1:00pm to test at a stream in Mission Trails Regional Park.  I tried my best to test at the same time everyday.  Getting all the data was time consuming and stressful at first, but after a few tests I started to get the hang of it and began enjoying it.  I learned many things like how dissolved oxygen can get into the water, how to take water samples, find water temperature, barometric pressure and much more. I’m really glad I did this project.

     At the end of testing I compared all the daytime dissolved oxygen levels to the nighttime ones. The results were very close.  Over a period of nearly a month my average results for daytime dissolved oxygen levels were 92% while the nighttime ones averaged to 85%. Daytime levels were greater. There were many factors that made these results true.  I thought of those during the hypothesis.

     Project Abstract:  Did you know that the absorbency material in diapers is also in cat litter?  This is because in diapers there are little absorbent beads.  When liquid splashes on the diaper the thousands of little beads expand to hold it. As you can see, this is also needed in cat litter, to absorb the urine of the cats. My experiment is testing whether the diaper is really more absorbent then a Shamwow or a sponge.  My formal hypothesis is that the diaper is going to absorb way more than the other materials. The question under investigation is, “Which Material Absorbs More Of Its Body Weight: A Diaper, A Shamwow or A Sponge?”  I weighed the materials, and recorded their weight, then  dunked then in water for a minute, weighed them again and recorded their weight. The diaper turned out to hold twenty-six times its body weight, the Shamwow ten times its body weight, and the sponge, four times it’s body weight. As you can see, the diaper won the competition by far.
