2013-2014 Events Life, Personal, & Social Anatomy & Physiology Designer Genes Disease Detectives Entomology Water Quality Earth + Space Science Astronomy Dynamic Planet GeoLogic Mapping Rocks and Minerals Chemistry Chemistry Lab Forensics Materials Science Physics Circuit Lab Compound Machines MagLev Engineering Boomilever Elastic Launched Glider Mission Possible Scrambler Scientific Inquiry Experimental Design Bungee Drop Technical Problem Solving Write It Do It
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 Forensic Methods: Polymer Testing Chromatography Mass Spectrometry Fingerprints DNA Glass Blood Spatters Entomology Seeds/Pollen Tracks and Soil Blood Typing Bullet Striations Given a scenario, possible suspects, and forensic materials, students are asked to solve the crime
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
