Open-Response Criteria
ROUND 1: CREATURES OF THE NIGHT (BIOLOGY & ADAPTATIONS)
Q1: Bat Ultrasonic Navigation Echolocation
Key Research Finding: Echolocation (biosonar). Bats emit high-frequency ultrasonic vocalizations (20–200 kHz). Sound waves bounce off insects/walls and return to the bat's ears, where acoustic processing maps distance and motion.
Q2: Vampire Bat Saliva Anticoagulant
Key Research Finding: Draculin functions as an anticoagulant (prevents blood clotting). It specifically inhibits blood coagulation factors IXa and X, keeping the host's blood flowing continuously so the bat can lap it up.
Q3: Spider Leg Mechanics Hydraulic Pressure
Key Research Finding: Hydraulic pressure / Hemolymph (blood). Spiders possess flexor muscles to pull legs inward, but lack extensors. They contract their cephalothorax to pump pressurized blood fluid outward into leg joints.
Q4: Owl Silent Flight Serrated Fringe
Key Research Finding: Fringed or comb-like serrations on leading flight feathers. These serrations break large air currents into micro-turbulences, muffling sound and allowing silent swooping.
ROUND 2: POTIONS & CHEMICAL HORRORS (CHEMISTRY & MATTER)
Q5: Dry Ice Fog Formation \(\text{CO}_2\) Sublimation
Key Research Finding: Solid Carbon Dioxide (\(\text{CO}_2\)) undergoing sublimation (solid directly to gas). The freezing cold gas cools surrounding water vapor in the air, causing it to condense into visible white water fog.
Q6: Glow Stick Light Chemiluminescence
Key Research Finding: Chemiluminescence. Chemical reaction between hydrogen peroxide and phenyl oxalate ester transfers energy to a dye, which releases photons of visible light without thermal heat.
Q7: Rotting Pumpkin Gas Methane (\(\text{CH}_4\))
Key Research Finding: Methane gas (\(\text{CH}_4\)). When organic pumpkin matter is trapped in oxygen-deprived conditions, anaerobic methanogenic microorganisms break down starches, producing flammable methane.
Q8: Heat-Releasing Brew Exothermic Reaction
Key Research Finding: Exothermic reaction. The chemical decomposition releases thermal energy into the surrounding environment as the chemical potential energy of the products is lower than the reactants.
