The Effect of Selenium Concentrations on the Growth of Cancerous and Noncancerous Skin Cells Kemi Adeleke - RMSST Abstract: This project will test selenium on the growth of cancerous and noncancerous cells. Purpose & Rationale: • The purpose of this research project is to test selenium on cancerous and noncancerous cells to determine if it causes cell death. • Those who consume selenium need to know the health effects it can cause. Background Information: Selenium has been known to reduce the chances of developing cancer. Humans should consume about 55 mcg per day. But too much selenium can cause selenosis poisoning. Methodology: There will be a low, medium, and high concentration of selenium tested on both cancerous and noncancerous cells. The control will have sterile PBS only. This will help show which concentration is recommended. Only live cells will be counted to show the effect the treatment had. Data Interpretation: Descriptive: mean, mode, range, and standard deviation Inferential: ANOVA test and chi-square Experimental Design Diagram Hypothesis: If selenium concentrations are tested on cancerous and noncancerous cells, the growth of these cells will vary. IV: selenium concentrations DV: number of viable cancerous and noncancerous cells No concentration (control) Low concentration Medium concentration High concentration Cancerous Cells 4 trials 4 trials 4 trials 4 trials Noncancerous cells 4 trials 4 trials 4 trials 4 trials The Effect of the Type of Music Program on Level of Hearing loss Kaegan Gregory RMSST Purpose & Rationale To determine whether a certain music program causes more hearing damage than others. By defining what program causes the most damage solutions for specific groups can be made. Data Analysis 1. Bar graph for each group 2. Frequency distribution 3. Median 4. Kruskal-Wallace Abstract Many musicians suffer from hearing loss. Is this happening in our schools at this very minute? Background Musicians in both classical venues and modern discotheques suffer from hearing loss. Methodology Students will be tested at 50, 500, 1000, 2000, 3000, and 4000 HZ at 25 dB Experimental Design Diagram Hypothesis: Different music programs will have different levels of hearing loss IV: Type of music program DV: Level of hearing loss Constants: Audiometer used, students tested, environment.

Purpose and Rationale Background Info & Previous Studies Methodology Data Interpretation Experimental Design Diagram • Concrete samples for each group will be mixed • Cementitious material and aggregate samples will be set aside for testing • Setting Time and Compressive Strength tests will be conducted for concrete samples • Fineness test will be conducted for cementitious material samples • Soundness test will be conducted for aggregate samples Purpose: • Create concrete using Type C fly ash, bottom ash, boiler slag, air, and water Rationale: • Creating concrete using only byproducts from coal-fired power plants can greatly reduce the carbon footprint as the byproducts are being recycled • This project will test whether or not coal combustion byproducts can serve as an equivalent substitute for standard concrete, without sacrificing performance. • CCBs (fly ash, bottom ash, flue gas, etc.) can be used in the manufacturing of other materials • Fly ash is usable as a substitute for Portland cement, acting as a pozzolan and cementing material • Bottom ash is a viable fine aggregate • Descriptive: Continuous (Mean, Range, Std. Deviation), Ordinal, Median, Frequency Distribution • Inferential: ANOVA, Chi- Square Abstract: • This project will test how well ozone can remove the pharmaceutical, penicillin, from water. Ozone and Pharmaceuticals in Water Ashley Hong Rockdale Magnet School for Science & Technology Purpose: To test which concentration of ozone can best remove pharmaceuticals. Rationale: The pharmaceuticals can affect human health Background: • Estrogen was found in the blood of male fish near a wastewater treatment in Britain and Arizona. • Penicillin is an antibiotic that is used for some injuries as well as sickness. • Ozonation is an alternative for purifying water in wastewater treatment. Methodology: The ozone generator will be built to add ozone into cold water with penicillin. Then, the water will be divided into four different samples: control, low, medium, and high concentrations of ozone. ELISA and zone of inhibition will be used to see if penicillin is removed from the water. The Spec20 will also be tested as well as absorption. Data Interpretation: The data is both qualitative and quantitative. ANOVA and Chi-Square will be used to determine significant differences. Descriptive statistics such as mean, range, and standard deviation as well as mode and frequency distribution will be calculated. Experimental Design Diagram Hypothesis: If ozone is added to the water with pharmaceuticals, then some of the pharmaceuticals would be removed. IV: Levels of Ozone and Pharmaceutical Penicillin None (control) Low Concentration Medium Concentration High Concentration 3 Trials 3 Trials 3 Trials 3 Trials DV: Amount of pharmaceuticals removed (absorbance values, zone of inhibition, and color from ELISA test) Constants: level of pharmaceuticals in water, aseptic and culturing techniques, and time exposed. The Inhibiting Effects of Different Treatments on Biofilms Abstract Biofilms are hard to disinfect. This project will find new disinfecting methods. Purpose and Rationale The purpose of this project is to find new treatment for disinfecting biofilms. Biofilms carry many infectious diseases. This project could help many people from getting infected. Background information • Biofilms occur when bacteria clump together on a solid surface. • Not even chlorine bleach can completely disinfect them. Methodology All bacteria will be grown into biofilms. Then all treatments will be applied in different amounts. Data Interpretation Absorbency and colony counts are quantitative measurements and will be graphed. ANOVA will be done to determine significant differences. The mean, range and standard deviation will be found. Hypothesis: There will be a significant reduction of the biofilms when exposed to different disinfecting methods.

Purpose To add the organisms and drugs to an artificial environment and observe health effects. Rationale Pharmaceutical pollution can cause serious damage to aquatic ecosystems. Background Pharmaceuticals enter aquatic systems through waste streams from waste water treatment plants. Aquatic organisms in affected areas are exposed daily to dangerous concentrations of drugs. Toxins build up and are transferred to humans as the organism is eaten. Methodology Organisms are placed into artificial environment Pharmaceutical drug is added to appropriate tank with correct concentration Observe health effects, record mortalities and compile data Data Interpretation Descriptive: mean, mode, range, standard deviation and frequency distribution Inferential: ANOVA and Chi-square IV: Concentration of pollutant No Pollutant (control) Low Concentration Medium Concentration High Concentration Prilosec 29 trials 29 trials 29 trials 29 trials Xanax 29 trials 29 trials 29 trials 29 trials Aleve 29 trials 29 trials 29 trials 29 trials Hypothesis: the pharmaceutical pollutants, Xanax, Prilosec and Aleve, will have a negative effect on the health of both Daphnia and Water Willows in the same affected area.
