Satellite Reception Without a Dish; Transmission of Information by Laser; Effect of Capacitor Dielectric Material on the Thermal Stability of High Frequency Oscillators. Projects that merely use electronics to study something else (e.g. hearing in birds) belong in another category (Zoology in this example).
7. Environmental Engineering: Projects which apply technologies such as recycling, reclamation, restoration, composting, and bioremediation which are directed to control the environment and/or the effects of pollution on the environment. Newspapers as Mulch; Oil Control; Water Hyacinth: Primary Water Treatment?; What Soil Conditions Best Control Soil Erosion While Assisting Growth?; Designing a New Home Sewer System. Studies of the effect of pollution on the environment at the basic science level belong in the appropriate basic science category.
8. Fluid Mechanics/ Aerodynamics/ Thermophysics: Experimental or theoretical studies in aerodynamics and propulsion of air, land, water, and space vehicles; aero/ hydrodynamics of structures and natural objects; acoustics; thermodynamics of energy production, energy utilization, and other industrial processes. Studies of the basic physics of fluid flow. Effect of Dimples on Golf Ball Flight; How Long Does It Take to Cook a Hot Dog?; Airfoil Stall Characteristics; Can Chaos Theory Predict Turbulence?; Low Drag Launch Lug for Model Rockets; Absorption of Acoustic Waves; Homemade Heat Pump. Fundamental thermodynamic properties (e.g. specific heat) belong in Physics & Astronomy.
9. Mathematics & Software: Studies in geometry, topology, real and complex analysis, number theory. Algorithm analysis and optimization, artificial intelligence, computability, computer graphics, modeling and simulation, programming environments and languages. Maximally Dispersed Points on a Sphere; Computer Modeled Evolution; Knot Mathematics; Coupled Chaotic Systems and Stability; Mathematical Optimization of Multiple Precision Multiplication; Partitions of Positive Numbers; Neural Network Model of Vision. Projects merely using mathematics to understand a different subject should be in that subject. Computer hardware projects belong in Electricity & Electronics.
10. Microbiology: Studies of epidemiology, genetics, growth, and physiology of bacteria, fungi, protozoa, or viruses. Studies of Light Producing Bacteria; Effect of Light Before and After UV Damage to E. coli; What Sugars do Yeast Use? Projects using bacteria as a tool to study another subject belong in that subject. For example, a study using bacteria to monitor the effectiveness of disinfectants belongs in Chemistry. Studies measuring antibiotic activity belong in Pharmacology.
11. Pharmacology/ Toxicology: Studies of drug or chemical effects at the cellular or organismic level on animals, humans, or plants. Effect of Caffeine on Daphnia; Effect of Insecticides on Mosquitoes; Vitamin Deficiencies; Copper Toxicity of Marine Embryos. Projects which study the effect of fertilizers on plant growth belong in Plant Biology.
12. Physics & Astronomy: Experimental or theoretical studies of the physical properties of matter, solar physics, astrophysics, orbital mechanics, observational astronomy, and astronomical surveys. Computer simulations of physical systems are appropriate in this category. Jupiter's Decametric Emission; Emissivity as a Function of Geometry; Solar Activity and Geosynchronous Satellites; Do High Temperature Superconductors have a First Order Phase Transition?; Chaotic Pendulum.
