  3. Anatomy & Physiology • Nervous System • Effect of Drugs • Integumentary System • Immune System • Study: Organs in each of the systems, how the systems interacts, disorders/diseases

  4. Designer Genes • Based on genetics and molecular biology • Genetics • DNA • Replication • Punnett Square • Hardy-Weinberg Equilibirum • Molecular Biology • Introns/Exons • Mitosis/Meiosis • Leading/Lagging Strand

  5. Disease Detectives • Focus: Environmental Quality • Hill’s Criteria for Causation • Epidemiological Triad + Chain of Transmission Triad • Types of Studies • Epi-Curves • Ten Steps to Investigating an Outbreak • CDC, the sponsor, has excellent resources

  6. Entomology • Must be able to identify insects from 30 orders and 100 families • Need to be able to classify insects by order and family • Can use a field guide • Prepare to see pictures and/or live specimens: either could be used • Prepare to use microscopes

  7. Water Quality • Identification of macroorganisms • Aquatic Ecology and Chemistry • Water Cycle/Nitrogen Cycle • Food Chains and Food Webs • Population Dynamics • Watershed Issues • Potable Water Treatment • Sedimentation Pollution • Harmful Species

  8. Astronomy • Will often show diagrams/spectra/curves • Types of stars • Kepler’s laws, rotation, circular motion • Deep Sky Object (DSO) ID • Allowed a binder of notes/laptop of notes • Don’t rely on your notes!

  9. Dynamic Planet • Focus: Glaciers • Traditionally allowed more notes • Basic Glacial Factors (What, Where, How) • Geology of Glaciers • Climatic Effects • Interglacial Periods

  10. GeoLogic Mapping • Be able to read and create topographic maps, geologic maps, and geologic cross sections • Infer things such as landslide risk and flood risk • Major Geologic Structures

  11. Rocks and Minerals • Need to be able to identify rocks and minerals to complete a written test • Should be able to identify them either based on pictures or specimens • Rocks: Igneous vs. Sedimentary vs. Metamorphic • Bowen’s Reaction Series (helps explain why certain minerals are found where) • Allowed to have a field guide

  12. Chemistry Lab • Lab Event • Focuses: Equilibrium and Stoichiometry • Equilibrium: • Le Chatelier’s Principle • Different Types of Equilibria • Titration • Stoichiometry: • Finding a Limiting Reagent • Finding Percentage Composition • Balancing Chemical Equations and then using Dimensional Analysis

  13. Forensics • Given a scenario, possible suspects, and forensic materials, students are asked to solve the crime • Forensic Methods: • Polymer Testing • Chromatography • Mass Spectrometry • Fingerprints • DNA • Glass • Blood Spatters • Entomology • Seeds/Pollen • Tracks and Soil • Blood Typing • Bullet Striations

  14. Material Sciences • Properties and Characteristics of Metals, Ceramics, Polymers, and Composite Materials • Intermolecular Forces • Crystal Structures • Common Atomic PAcking • Surface Chemistry • Material Classes

  15. Circuit Lab • Lab Event • Deals mostly with DC Current • Ohm’s Law • V = IR • Reading Resistors • Conventional Current vs. Electron Flow • Kirchhoff’s Laws

  16. Compound Machines • New Event • A compound machine is a device that is made up of two or more simple machines. • May need to calculate IMA (ideal mechanical advantage), AMA (actual mechanical advantage), and efficiency

  17. MagLev • Build Event/Written Test Event • Build a magnetically levitated car to run to a specified line • Must predict the time the car will take • Magnetic vs. Non-Magnetic Material • Polarity • Earth’s Magnetic Field • Magnetic Domains

  18. Boomilever • Build Event • Built to hold a specified weight a given distance from a vertical surface

  19. Elastic Launched Glider • Build Event • Consists of two parts: Flight Log, Glider that is launched by the pulling and release of a rubber loop

  20. Mission Possible • Build Event • Construct and write a paper about a Rube Goldberg-esqe device • A modest number of steps that work well is better than a large number that are unreliable! scioly.org • Touching the device results in loss of points • Let the machine do the work • Un-official Categories: Mechanical Energy, Electrical Devices, Chemical Devices, Thermal Devices, and Optical Devices • Create an “Energy Transfer” List

  21. Scrambler • Build Event • Create a device that transports a Large Grade A uncooked chicken egg 8-12 meters along a straight track as fast as possible • Length unknown before event • Score = 2 * [running time in seconds + stopping distance in cm] • Lowest score wins • Best of two runs

  22. Experimental Design • Asked to create and to write-up an experiment • Grading rubric available online but not allowed in testing area • Several key parts: • Statement of Problem + Hypothesis • Variables + Control (Standard of Comparison) • Procedure • Observations and Statistics • Analysis + Experimental Error • Conclusion + Applications and Recommendations for Further Experimentation

  23. Bungee Drop • Two trials between 3 and 7 meters: height not announced beforehand • Weights: 25-500 grams; weight not announced beforehand • Necessary to calibrate the device: could use a formula or calibrate for weight and height • Goal: Get your device to drop as close as possible to the floor below, without touching • Better to get a higher score than to touch the floor, which automatically ranks you behind others

  24. Technical Problem Solving • Possible Lab Event • Topics: Electrochemistry and Thermodynamics • Collect and analyze data to solve mathematical analysis • Wide range of test topics; good for those with a wide base of science knowledge

  25. Write It Do It • Two team members: “The Writer” and “The Doer” • “The Writer” • 25 minutes to write instructions • Use symbols that can be typed on a standard keyboard by pressing one button or shift + button • Must define all abbreviations and cannot use diagrams • “The Doer” • 20 minutes to build from his/her teammate’s instructions • May have excess materials! • This event requires excellent communication!

  26. Any Questions? • Advise you to try out for 3-4 events • Studying for one event may help you in studying for another • Ex. Forensics and Material Science work well together
