More details on the Skinner Middle School students’ Science Fair projects:

Lia Dino
Grade level:  7
School:  Skinner Middle School
Name of the Project: The Effect of Specifications of PET Bottles on the Solar Dissenfection of Water
Lia investigated how different disposable water bottles allow for the transfer of U.V. light to kill pathogens in drinking water supplies.
Brief Description of the Project:
Globally, more than 3.4 million people die from water-related diseases every year, for the experiment I chose to investigate a solution. That solution is solar water dissenfection. In addition to finding the solution, I chose to study how the different shapes, opacities, pigmentation, and thickness of four different bottles affect the dissenfection of the water in them.  I used two types of water, a purified lab water with E.Coli K-12 in it, and a local lake water.  I used natural light photons to disinfect bacteria in the water. I then collected samples and transferred the bacteria on to Petri dishes and completed a cell count. Overall, I found out that solar water dissenfection is an efficient way to decrease the number of bacteria in the water. The best bottle to use to disinfect is a clear, thin bottle.

Sophie Scholl
Grade level:  8
School:  Skinner Middle School
Name of the Project: The Oleophilic Ability of Botanicals in Cleaning Oil from Water
Sophie investigated how natural plant materials could be used to mitigate environmental contamination from oil.
Brief Description of the Project:
This study investigated the oleophlic ability of botanicals with a goal of finding a natural alternative to cleaning oil spills from bodies of water.  Foliage from these plants were put in a bowl with 2000 grams of water and 200 grams of oil for an hour, then removed.  The post and pre weights of the plant were taken to determine the amount of oil absorbed by the botanical.  Through data collection, it was found that Jerusalem Sage is the most effective in cleaning oil spills.

Juno Gregg
Grade level:  8
School:  Skinner Middle School
Juno investigated how salinity of water affects the ability of sunlight to travel through it with connections to ecology etc.
Brief Description of the Project: 
This study investigated how increased amounts of salt in fresh water affected the translucent quality of the water. A test apparatus was built and increased amounts of salt were added to distilled water. A 1000 lumen flashlight was shone down into the water and reflected through a mirror. A photographic light receptor took the readings of light reflected in foot-candles. The findings show that when salt is salt is added, the amount of foot-candles decreases. This project could be applied to modern society by finding salinity, therefore finding what animals could live in a localized area. Also different contents could be used as the independent variable to test water quality.
