In this study, noise was generated inside an insulated tube through barriers of paper, and recorded outside the tube. Our results indicate that the decibel loss across the barrier increases at a decreasing rate as the barrier's thickness increases.

We use the Gini coefficient to measure the distribution of English-speaking friends and home language-speaking friends among Vantage College students over time. Our results indicate that English-speaking friends are less evenly distributed than home language-speaking friends, and that the unevenness of the distribution increases over the year spent in Vantage College.
Our objective is to investigate the relationship between the quality of stars and the box office earnings of their movies. We use financial and awards data to determine the quality of stars, and relate it to box office earnings using linear regression. Our conclusion is that there is a positive relationship between star quality and box office earnings, but that the correlation is weak.
The aim of the study is to compare the fuel consumption between traffic circles and normal crossroads, and determine which one is more fuel efficient. We determine that, under certain common constraints, the traffic circle is more fuel efficient.
We investigate whether the time taken for a stock price to stabilize after a recall is issued depends on the time taken to issue a recall. In this study of 10 automobile manufacturing companies, we determine that there the time taken to issue a recall does not have a significant effect on the time taken for the company's stock price to recover.
When water is released from a tap to the sink, a circular hydraulic jump appears on the surface of the sink. We investigate the relationship between the distance the water falls and the radius of the hydraulic jump, and determine it to be positive and linear.
The goal of our research is to find the optimal location of a new convenience store for students in five different residences. We consider this from the point of view of travel distance, and use Dijkstra's algorithm to determine optimal locations in terms of average distance and minimized maximum distance.
Can the thermal from hot water be transferred to electricity and be used to charge a phone?7/8/2017 We investigated the potential use of thermoelectric modules for real life applications. By using temperature difference, we tried to transfer thermal energy to electricity. Temperature difference here was a model of energy lost in daily life. The aim of the experiment was to explore the transfer between different energy, and increase efficiency of such energy transfer. Therefore, answer the question how can we use energy waste and save energy. The results of the experiment could be significant for thermal energy’s future use in our daily life and in new product design. We found that it is possible to use not only one thermoelectric module to transfer thermal energy to electivity. The effects of gradient and friction on a bicycle's stopping distanceWe investigate the effect of a surface's coefficient of friction, as well as the effect of a surface's gradient, on the velocity and stopping distance of a bicycle.
In this research, we are going to measure gravitational acceleration (g) precisely in Vancouver through four different methods: using spring scale, water drop, ticker-tape timer and single pendulum. The equipment of these experiment will be based on physics lab. The aim of this experiment is to explore which gravitational acceleration (g) measurement method has a higher accuracy with limited cost. After data collections, we will compare results from different methods with theoretical gravitational acceleration in Vancouver, 9.80921 m/s2 (Chanson, 2009). to analyze the advantage and disadvantages of each methods. Our experiments are simplified repeated experiments. The results of this experiment could be used to design homemade gravitational acceleration measurement with limited cost and a simple method.
The speed of sound in different temperatures and humidity is a fundamental concept in the field of physics. In this research, we investigated the variation of the speed of sound with temperatures and humidity at UBC, Vancouver. We concluded that there is a possible relationship between the speed of sound and temperatures, and a relationship between the speed of sound and humidity.
