Welcome YES Club to our project!!

Last Thursday, November 17, we had a meeting with members of the YES Club, Glenn and Kassandra.

We think the meeting was a great success and we look forward to work in cooperation with the YES Club.

WELCOME YES CLUB!!!!!!!!!!!!

Water Tasting Experiment

A group of students conducted a water tasting experiment during the Community Expo 2011-1. The experiment consisted on having volunteers taste different brands of bottled water and tap water with the goal of identifying tap water.  Before they drank from the different samples, participants were asked whether they drink more bottled water or more tap water.

There were a total of 90 participants

51% drink mainly bottled water

37% drink mainly tap water

12% drink equal amounts of bottled and tap water

——————————————————-

 

Out of the participants that mainly drink bottled water:

56% were not able to identify tap water

44% were able to identify tap water

 

Out of the participants that mainly drink tap water:

61% were not able to identify tap water

39% were able to identify tap water

 

Out of the participants that drink equal amount of bottled and tap water:

54% were unable to identify tap water

46% were able to identify tap water

 

58% were unable to identify tap water

42% were able to identify tap water

——————————————

 

29% were unable to identify tap water and indicated that they drink mainly bottled water

22% were unable to identify tap water and indicated that they drink mainly tap water

7% were unable to identify tap water and indicated that they drink equal amount of bottled and tap water

 

22% were able to identify tap water and indicated that they drink mainly bottled water

14% were able to identify tap water and indicated that they drink mainly tap water

5% were able to identify tap water and indicated that they drink equal amount of bottled and tap water

 

Conclusions:

Most people, 58%, were unable to identify tap water.  When comparing people who mainly drink bottled water and people who mainly drink tap water, there was only a 5% difference in terms of ability to identify tap water.  It seems that bottle drinkers are more likely to identify tap water.

A follow up study is required to see whether participants like the taste of tap water.  For instance, participants in a future test could be asked to rate the samples of water according to taste.  Also, we could try to get a bigger sample of participants.

Water Clock F.A.Q by Analia Perdomo

What is a Water Clock?

  • A Water Clock is a timekeeping device that uses the flow of water to measure the current time.

What is the purpose of the Water Clock Project?

  • The purpose is to have students come together and work to build a water clock as a symbol of sustainability. In addition, it’s for students to get involved and encourage other students and teachers engage in proactive behaviors. In the process, students have the opportunity to develop communication skills, critical thinking skills, cross-cultural understanding, and improve civic responsibility.

Who invented the Water Clock?

  • Due to their great antiquity, where and when they first existed is unknown. The bowl-shaped outflow is the simplest form of a water clock and is known to have existed in Babylon and in Egypt around the 16th century BC. Other regions of the world, including India and China, also have early evidence of water clocks, but the earliest dates are less than certain. Usually, however, some authors write about water clocks appearing in China as early as 4000 BC.

Why is sustainability important?

  • Sustainability is actions that we take today that will make a difference in our future. In order to avoid limiting resources in the future we need to start making good decisions for our environment today. With the Water Clock project, it emphasizes the importance of our natural resources and that the resources we have available we need to use them responsibly. Building a Water Clock is a symbol of sustainability and can minimize the destructive influence on the environment.

How can you build a simple Water Clock?

  • To build a water clock you need 2-liter bottles. You would cut the bottom off and draw a line near the edge. You will then remove the cap and put a rubber stopper that has a hole in it. Once you have the stopper in put a vinyl tube in the hole and clamp the tube. Then place bottle upside down in 4-inch diameter ring support that is in a ring stand. Place the rubber-tubing end in a beaker. Gradually you will let the water drip in the beaker. You need to mark the bottle every ten minutes. Pour water back into the bottle and do again marking every five min.

Where can we find an actually Water Clock?

  • There are nearly 30 water clocks around the world today, including one at Europa-Center’s The Clock of Flowing Time in Berlin, one at The Children’s Museum of Indianapolis in Indianapolis, Indiana, and the Shopping Iguatemi in Porto Alegre, Brazil. There are other modern designs of water clocks, including the Royal Gorge water clock in Colorado, the Woodgrove Mall in Nanaimo, British Columbia, Hornsby Water Clock in Sydney, Australia and in the Abbotsford Airport in Abbotsford, British Columbia.

What is the Water Clock Project?

The Water Clock Project in an attempt to maximize the learning environment and take it outside the classroom.  It is a entirely student driven program provided through service-learning.  Although professors from art, architecture, engineering, and psychology are available, their involvement is merely as advisors or mentors.  The students have the main responsibility to identify, plan and structure their activities.

The main purpose of the Water Clock Project is to have students from different majors working together with three common goals.

  • The first goal is to build a water clock as a symbol of sustainability.
  • The second goal is assist students gain insight or understanding about interrelatedness.  To attain this second goal students
  1. Get involved in creative processes and professors encourage students to engage in proactive behaviors
  2. Form delegations in charge of activities/projects that they have chosen.  Since these activities/projects are always part of a larger goal, they also have to overcome challenges to maintain lines of communication open.
  • The third and final goal is to foster career orientation.  Student’s knowledge and interest becomes the foundation that allows creation of useful experiences related to student’s academic goals.  In the process, students have the opportunity to develop communication skills, critical thinking skills, cross-cultural understanding, and improve civic responsibility.
