Challenges
Please read the descriptions and rules carefully. Judge's decisions are final.
| Senior Events | |
|---|---|
| Chemistry | Chemistry: Students will apply the knowledge and technique of volumetric analysis to determine the concentration of Vitamin C in fruit juice. This is not the same event as in KSC 2010, despite the similar objective! Advanced preparation : Students shoulda) Review the basic principles, concepts and techniques of volumetric analysis. b) Review/study the principles and concepts or redox reactions. c) Familiarize themselves with the use of indicators, specifically how colour change indicates the end point of a titration. |
| Biology | Students will use the scientific method to generate a hypothesis based on the ability of various compounds to inhibit bacterial growth. Students will collect data, and based on the results, determine if the results support the hypothesis. |
| 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. |
| Physics | Physics: Students will conduct an experiment involving impulse, momentum and force . Advanced preparation: Students should review the concepts of impulse, momentum and Newton's Second Law. Students should also be familiar with the concept of a force-time graph and how it is used in impulse-momentum analysis. The team can bring in with them a copy (unannotated) of the Physics 12 formula sheet and a (non-programmable) calculator. |
| Design | Rocket Cars: The goal of this event is to create the fastest rocket car propelled by compressed air and water in a 2 Litre pop bottle. This is a pre-build event – teams should arrive with their device already constructed. Pressure inside the bottle will force the cork to fly out of the back of the pop bottle, and propel the car forwards. As the pumped bottle is projected forward with significant kinetic energy, teacher supervision is required for any school-based testing of the rocket car. Please be extra safe. The winner will be the vehicle that takes the least time to break two laser beams separated by 30 feet. Advanced Preparation: Build the rocket car according to the attachment.

| Junior Events | |
| Math | Students will make 3-dimensional objects from one provided sheet of Bristol Board. Advanced Preparation : Students should review how to make cylinders from a 'net'. They may bring a geometry set with them (compass and ruler will be helpful) |
| Geology | Students will delineate a watershed and answer questions regarding watershed hydrology. Advanced Preparation : Students should review topographic maps and basic measurements (scale, distance, area, elevations). Students should be familiar with SI units and conversions of distance, area and volume. Students should be familiar with watersheds (drainage basin) and the hydrologic cycle. |
| Physics | Students will use ammeters and voltmeters to try and identify the 'mystery circuit' which lies inside a black box and is not directly observable. The circuit will consist only of a power supply, wires and resistors in standard, straightforward configurations. Advanced Preparation : Review the concepts of voltage, current, resistance, Ohm's Law, Series, Parallel and Mixed Resistor Circuits. Review how to use an ammeter and voltmeter properly. |
| Design | Popsicle Bridge: The goal of the event is to prebuild the strongest bridge possible with 75 Popsicle sticks and white glue. The bridge must span a 500 mm and a matchbox car must be able to traverse the bridge on a construction paper deck. On the day of the event, the bridge will be subject to load and the bridge that carries the highest load will be the winner. See the attachment for more details. READ CAREFULLY AS THERE HAVE BEEN CHANGES IN THE RULES. Advanced Preparation : Prebuild the bridge according to the specification provided in the attachment.

| Jeopardy | Students will compete in a Science version of the popular game. Note there will be one buzzer per team. Advanced Preparation : Review Science 8-10 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. |
