Objectives/Goals The objective of my project is to determine which ages best understand emojis. Methods/Materials Ten subjects from each of the age groups tested were asked about their expos…
Microbiology (Medical) (Junior Division Only)
Third Award
Objectives/Goals This experiment studied which bacteriophage strain (T4r+, phiX174, or P1) would lyse a larger area of various Escherichia coli strains (B, C, K-12, and K-12 pilus forming) w…
Chemistry
Objectives/Goals The experiment was to measure the amount of force that hair which has been bleached, dyed, and lightened with hydrogen peroxide can withstand before breaking. It was expecte…
Applied Mechanics & Structures
Objectives/Goals Compare 3 bridge designs with regards to their ability to hold a fixed amount of weight. The 3 bridge designs were Arch, Cable-stay, and Beam. We also considered the amount…
Product Science (Biological) (Junior Division Only)
Objectives/Goals The objective is to find which material can help to keep cut roses freshest for the longest period of time. We believe that the flower that uses flower food will last the lo…
Applied Mechanics & Structures
Objectives/Goals My objective in my project was to figure out which material could stand up against a simulated tsunami. My hypothesis is that the steel block will perform better than the ot…
Product Science (Physical) (Junior Division Only)
Objectives/Goals The purpose of this project is to burn different types of wood to see which one lasts the longest. The results will help people choose the longest lasting wood to burn in a…
Chemistry
Objectives/Goals The goal of this experiment is to investigate whether naturally-collected waters are better than synthesized salt solutions for water electrolysis. My hypothesis is that tho…
Toxicology
Objectives/Goals My objective was to investigate how natural spices effects an organisms heart rate. My second objective was to see if the heart rate stayed constant. Methods/Materials The m…
Applied Mechanics & Structures
Objectives/Goals My objective was to find out if hot or cold temperatures would affect how high tennis balls would bounce. Methods/Materials Materials included tennis balls, oven, freezer, c…
Chemistry
Honorable_mention Award
Objectives/Goals It is well-known that salts help melt ice/snow faster. I wonder if ice will melt faster in fresh water or salt water. Methods/Materials two bowls; ice cubes; table salt; cho…
Aerodynamics/ Hydrodynamics (Junior Division Only)
Objectives/Goals My objective is to demonstrate that at certain level of a propeller angle and at certain level of RPM's can generate more propulsion by the wind generated by an airplane. Me…
Aerodynamics/ Hydrodynamics (Junior Division Only)
Objectives/Goals This project investigated various blade configurations in order to optimize wind turbine efficiency. Methods/Materials * Build a wind tunnel; assemble the Kidwind Wind Exper…
Electronics & Electromagnetics
Objectives/Goals The goal of my experiment was to see if it is possible to transfer power wirelessly, and to see if changing the diameters of the transmitter and receiver coils will affect t…
Physics & Astronomy
Objectives/Goals The objective was whether the change in elevation would affect the performance of different masses (5g, 6g, 10g, and 12g) on a Straight Slope and an Angled Curved Slope. Met…
Physics & Astronomy
Objectives/Goals The objective is to determine whether sound-wave-induced vibrations would promote the freezing rate of pure, distilled water using researches conducted on the Mpemba Effect…
Biochemistry/ Molecular Biology
Objectives/Goals My objective was to use titration of orange juice with iodine to find when an orange contains the highest amount of Vitamin C after being picked, so that it would be the hea…
Microbiology (General)
Objectives/Goals The main objective of this experiment was to try and determine if cell surface hydrophobicity (CSH) of algae differs among taxa, and also what role hydrophobicity plays in h…
