Water Propelled Rocket CONTEST
The purpose of this project is to launch a rocket propelled by water. The rocket must not be taller than 60 cm, with an aerodynamic design and its own stand. We are going to launch the rockets in the football field and the rocket that stays the longest time will the the winner. For this first project there is no write up.
VIDEO
The second phase of this project is to create a video launching the rocket as a projectile and with different amounts of water and angles.We will calculate the initial velocity and max. height.
First Part
Test your rocket launching it vertically with 3 different amounts of water (for example 67%, 50% and 33%). This to determine which combination of air and water will provide more force (thrust).
With the best combination, proceed 3 launches with angles 30, 45 and 60. Determine the time and horizontal distance and develop all the formulas for a projectile. Assume that air resistance is non existing (not in reality). Calculate the efficiency of your rocket.

CONTEST: SPRING POWERED CAR DUE: OCTOBER 11 (FriDay)
Your task is to build and test a car built from common household materials and powered by spring(s). The only restriction is that the car must be less than 0.5 kg and has a minumum of 2 wheels. We are going to test your car in the hub to find which car achieves the longest displacement. Test your car before the due date and use your creativity (think outside the box) to win the contest. Use the physics principles we discusses in class to desing your winner car.
CONTEST: TREBUCHET CONTEST DUE: November 15 (FRIDAY)
The challenge is to build a trebuchet that will throw playdough the maximum horizontal distance. See the attached video:

Look under "Senior design 2013.pdf" but in our case, the structure must fit into a cube 40 cm per side.
Attach a one page description of the mechanics of your design.

CREATE A DIFFERENCE
The purpose of this assignment is to use our knowledge of energy and expand to energy conservation. During one week (started April 10) you were requested to observe all aspects of energy usage in your home, including use of appliances, heating, lighting etc in addition to current practices in terms of use of resources like packaging, waste etc. In addition, you have to become familiar with the way that BC hydro and gas is paid indicating the units of energy used by the companies. Your task is to propose realistic goals in energy conservation and quantify the savings per year. Your report is no more than two pages long and "straight to the point." Please request your parents/guardians to sign your report.
