The Water Bacteria Lab
Description
I have grown the most in the subject of gathering evidence from test subjects from the real world at the beginning of the year I had issues gather evidence from others I could not tell what question to ask the person. Now I can ask simple and fast questions that people can simply answer.

Which brand of bottled water contains the most colonies of bacteria.
Abstract
The point of this experiment is so that we can find out which brand of bottled water is the cleanest bacteria wise. You will need Paddle testers, different brands of bottled water (we used nine in this experiment,) a room temperature incubator, and a control, which would be any water that you are certain will have bacteria. We will be using paddles slides to cultivate the bacteria. Once we place them in an incubator, small oval or circular dots will appear in different colors (such as white, red, tan, yellow, black, etc.) These are colonies of bacteria. In order to count each bacteria you would need a microscope so for the purpose of this project we will only count the colonies. Our results were: Control- 48, Aspen pure- 7, Fiji- 0, Evian- 0, Smartwater- 0, Arrowhead- 1, Propel- 0, Dasani- 0, Niagara- 0, kroeger- 0. One problem that we ran into is the paddle testers, the ones we used for this experiment were expired so the results might it be accurate. We ordered new ones but they were placed back order. They won’t get here until November so when we get the we will redo this experiment.
Why this experiment?
The point of this experiment is so that we can find out which brand of bottled water is the cleanest. Claire Bedford did an experiment in 5th grade where she had to determine which type of water (out of river water, faucet water, bottled water, and filtered water) contains the most bacteria colonies. also, The Telegraph states that there is more bacteria in bottled water than tap water. We will be using paddles slides to cultivate the bacteria. Once we place them in an incubator, small oval or circular dots will appear in different colors (such as white, red, tan, yellow, black, etc.) These are colonies of bacteria. In order to count each bacteria you would need a microscope so for the purpose of this project we will only count the colonies.
Hypothesis
If bottled water contains bacteria than we believe that Smart Water will contain the most because they stated on their site that there were bad types of bacteria in their water.
Materials needed:
-Paddle testers
-Different types of bottled water
-Incubator
Procedures
First, you buy 9 different types of bottled water (for this experiment we used Aspen Pure Rocky Mt. Water, Fiji Natural Artesian Water, Evian natural spring water, Glaceau Smart Water, Arrowhead spring water, Propel water with electrolytes, Dasani purified water, Niagara purified drinking water, Kroger purified drinking water. Then, you pour some of the water from each bottle into separate containers. Next, you put the paddle testers into the water and leave them for three minutes each. Last, you pull them out and put them back into their container and place them into an incubator that keeps room temperature. Once this process is done and you leave the paddle testers in the incubator three days, you pull them out and count all the colonies of bacteria on the paddle. Be sure to list your results!
Results:

Research:
Aspen Pure natural water.
At the bottling center, Aspen Pure natural water travels through a five-step filtration and purification system. Upon completion of the filtration process, the water is ozonated and then the bottling process begins. The bottles are filled with water, labeled, sealed, inspected, packed and prepared for shipping. The end result delivers customers clean, high-quality bottled water.
Fiji natural water.
Industrialized country. It is bottled at the source in the remote Yaqara Valley on the island of Viti Levu.ne hundred percent of FIJI Water is from a single source in the pristine, tropical Fiji Islands, an archipelago of over 300 islands nestled in the South Pacific, more than 1600 miles from the nearest industie.
Evian natural spring water.
The origins of evian® Natural Mineral Water date back thousands of years to the very birth of the French Alps. Over several ice ages, a natural filter developed, creating a one of a kind haven for the planet’s most precious treasure.
Smart water.
“Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the United States Food and Drug Administration, Food and Cosmetic Hotline (1-888-723-3366).” “Some persons may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons, including, but not limited to, persons with cancer who are undergoing chemotherapy, persons who have undergone organ transplants, persons with HIV/AIDS or other.
Arrowhead.
There are over three hundred fifty-eight million trillion gallons of water on Earth. But not all water is created There are over three hundred fifty-eight million trillion gallons of water on Earth. But not all water is created equal. Arrowhead® Brand 100% Mountain Spring Water comes only from carefully selected mountain springs that are continually replenished. What starts out as rain and snow, soaks into the ground and is filtered naturally by the earth with a distinct composition of minerals to create our crisp, refreshing taste.
Propel water with electrolytes.
The quality standards of bottled water provide the maximum legal limits for a variety of substances that are allowed in bottled water, along with their monitoring requirements. The substances include microbiological contaminants, pesticides, inorganic contaminants, organic contaminants, radiological contaminants, and others. The standards have been established by the United States Food and Drug Administration (FDA), based on the public drinking water standards of the United States Environmental Protection Agency (USEPA). CDPH adopts the FDA regulations pertinent to the quality standards of bottled water.
Dasani purified water.
In designing DASANI to be the best tasting water, we start with the local water supply, which is then filtered by reverse osmosis to remove impurities. The purified water is then enhanced with a special blend of minerals for the pure, crisp, fresh taste that’s delightfully DASANI.
Niagara purified drinking water
Our water is tested by requirements that surpass those set in place by the United States Food and Drug Administration (FDA) or the Environmental Protection Agency, so you know the water you’re drinking is safe and healthy for the family.
Kroger purified bottled water
Minimally processed products usually contain a very short ingredient list. For the most part, they are comprised of simple ingredients that you would have found in your great grandmother's kitchen 100 years ago.This product is in the top 10% of the products in its category.Purified water is filtered tap water. If tap quality is good in your neighborhood, you don't need this.

- Describe a concept you have learned and how it applies to your contraption:
Mechanical advantage, Work, Efficiency, Simple Machines, Potential or Kinetic Energy, Momentum, Projectile Motion, Force
-In this project we learned how to determine potential energy based upon the previous object's
kinetic energy.
- What skills did you learn ? (construction, problem solving, collaboration, design, project management, etc...)
-I learned that it can be very hard to work in a group were all the members including myself get sidetracked easily
- What steps were most challenging to make work? (How did you troubleshoot or redesign)
-We had trouble getting our pulley step and the dominos to get to work. It was difficult because they didn’t want to fall over at all.
Calculations
Metal ramp: V=51cm/s
4,000J
Pulley: ME=2
Domino ramp: V= 55cm/s
5,050J
Ramp 1: PE=1,410
V=55cm/s
Steps:
Step 1: We pump the ball pump releasing air into the tube that knocks the ball forward.
Step 2: Ball falls through wood and into ramp 1.
Step 3: Ball drops down from ramp and into wood wedge.
Step 4: Wood wedge knocks marble into Ramp 2.
Step 5: Marble rolls down ramp and hits dominos.
Step 6: Dominos fall into flat domino.
Step 7: Flat domino slides down ramp and into marble.
Step 8: Marble launches into metal ramp.
Step 9: marble rolls down metal ramp and into three other marbles.
Step 10: Four marbles slide into a metal weight.
Step 11: Weight falls and sets of teeter totter.
Step 12: Teeter totter launches golf ball into domino.
Step 13: Domino trips string.
Step 14: Sting pulls setting off mouse trap.
Step 15: Mouse trap pulls out jenga block.
Step 16: Jenga block flies into cardboard wall.
Step 17: Cardboard wall with nail folds and pops balloon.
