2018 Event Descriptions

(Most events change each year. Event Descriptions may be revised at any time.)


Please read the descriptions and rules carefully. Judge's decisions are final.
 

 

  SENIOR EVENTS
Chemistry

Students will have two tasks to complete. Task 1 will be to determine the acid content in consumer beverages through titration. Task 2 will be to determine the contents of an unknown organic molecule mixture through thin layer chromatography. Students are only permitted scientific calculators (no graphing calculators), pens and/or pencils in the laboratory. All personal electronics (including smartphones, wearable devices, etc...) are strictly forbidden.

Advance preparation

1) Review concepts of stoichiometry and acid/base (including titration).

2) Review concepts of thin layer chromatography.

Biology

Students will perform a simulation of an assay or test that is widely used in research and diagnostic laboratories.  Each group will be provided with written material describing the scientific principles underlying the assay, a particular pathological process, and the clinical history of several different hypothetical patients.  There will be questions to answer on the written material. 
 
advanced preparation: Read units covering proteins, enzymes, white blood cells and antibodies.

Senior Jeopardy

Students will compete in a Science version of the popular game. Note there will be one buzzer per team. 

advanced preparation : review grade 11/12 Science (Biology, Chemistry, Math, Physics) curriculum. Calculators, PDAs, and other electronic devices are not allowed. Notes - electronic, written, or otherwise - are not allowed. Pens and blank paper will be provided.

Design

Design and build a homemade hovercraft, and then race it on a 12’ long course. For detailed rules see the attachment

advanced preparation:: Design and build the hovercraft according to the detailed rules (see attachment).

PHYSICS

Students will measure light from a gas discharge using a grating spectrometer and use it to identify an unknown gas.

Advanced Preparation: Review the physics regarding the wave nature of light including the grating equation. Make sure you know how to make a linear graph and find the line of best fit.​

 
Junior Events
Geology

Students will answer questions regarding the basic geology,  hazards and potential mitigation of hazards in an active volcanic region.

advanced preparation

i) Students should review the two basic types of volcanoes and their eruptive styles.

ii) Students should review associated hazards of volcanic eruptions along with some simple measures to mitigate potential hazards.

iii) Students should review basic rock types (IG, SED, META), and be able to identify common rock types in hand samples (e.g. shale).

iv) Students should should bring a scientific calculator. No phones allowed.

Physics

Can You Predict What will Happen???

There will be several physics related scenarios described to you. For each one, you will predict the outcome by voting for options in a PollEverywhere competition. Then we will show you the scenario and outcome (either live or in a video). You will be graded on how you place in the competition.

Design

Student will build a ‘sailboat’ that uses the power of a crosswind to race down an artificial pond in the least time possible.

advanced preparation: Design and build according to the detailed rules below

MATH

Students will calculate the volume of right rectangular prisms and right square pyramids. A non-programmable calculator will be needed, but no formula sheets are to be brought in to the event.

Advanced preparation: Students should review volume formulas for the solids in question.

JEOPARDY

Students will compete in a Science version of the popular game. Note there will be one buzzer per team.

advanced preparation: review grade 8, 9, 10 Science (Biology, Chemistry, Math, Physics) curriculum. Calculators, PDAs, and other electronic devices are not allowed. Notes - electronic, written, or otherwise - are not allowed. Pens and blank paper will be provided.
