=Should you be afraid of what you consume?=

**By Molly** For my project I decided to ask the question, “Does BPA leach into your water or food?” On my poster I have included the effects ([|written by John Bucher and Mike Shelby]) and ways to avoid BPA. Also I conducted an experiment with crickets. In one cage ten crickets drank BPA contained water for two weeks which I heated in a type #7 water bottle for 1 minute and 30 seconds. In the other cage ten crickets drank purified tap water. To receive accurate results I sent water samples to a company which analyzes water called Impact Analytical. The first sample I heated in a type #7 water bottle for 1 minute 30 seconds. In the second sample I heated in a type #1 plastic cup with saran wrap covering it for 1 min 30 seconds also. I still have not received the results. Below some ways to avoid BPA are listed. Ways to avoid BPA: -BPA leaches into canned food from lining (limit the amount of canned food you consume) -Avoid type #7 plastics, use types #1, #2, and #4 which do not contain BPA. -Glass baby bottles are much better than plastic ones. -Dull or unclear plastics do not have BPA in them. -If you get metal water bottles, get them without the plastic coating.

=Which water sample has the best quality based on pH, dissolved oxygen, turbidity, phosphates, and nitrates? =

My project was on water testing. The five water tests that I used were [|pH], [|dissolved oxygen], [|turbidity], [|phosphates], and [|nitrates] . I used 12 different water samples. The samples consisted of lakes, tributaries, creeks, ponds, and tap water. My control was purified drinking water. The best water was a pond (#12) based on pH. Based on dissolved oxygen, the best water was a creek (#5). A creek (#6) was the best water based on phosphates. For nitrates, a lake (#8) was the best. The data for my turbidity test went wrong. For three of my tests, I used a sensor that connected to the computer. For the other two tests, I used manual tests that were estimates.

For my tests on the computer I used [|Vernier probes] . The links above lead to the definitions of each water test. = = = =

This is chlorinated water. I will only pour a small amount of this chlorinated water in with the dirty water. Then I took coffee filters and filtered the water. this is chlorinated water. The water will be cleaned then released into nature. my sources were my dad at [|www.123mc.com] Use chlorine and get dirty water put dirty stuff in it, **AND HAVE FUN WITH IT!**

=Can heat take the salt out of water? By Jason= media type="custom" key="3575620" This project proved that heat can take the salt out of water. It also proved that my project worked. If you have trouble finding this just try to make your own using these ingredients for experiment one use two water jugs, two water bottles, two straws, two liters of salt water for each jug. For experiment two get one liter of salt water, one bowl, one cup and some Saran wrap. You will also need a pH measure. []

__**Building An Aquifer**__ By: Aliyah
**Question=How do contaminants spread into drinking water? The aquifer model as you can see below is an aquarium filled with pink sand, multi colored rocks, and green felt. I poured powdered cocoa and watched it spread. I also made a poster to explain how the contaminants spread into the water. My objective is to illustrate how water is stored in an aquifer,how groundwater can become contaminated, and how contamination ends up in drinking water. This demonstration** **make you understand what happens above the ground can potentially end up in drinking water. Resources= __Watershed Patch Project__ pg.37** media type="custom" key="3681541"

=Grey Water By: Erica= media type="custom" key="3576714" Even though my blabberize told you a lot about my project there is still more information on grey water. For my experiment I took two bean plants and I watered one of them with grey water (reused water) which can also be called brown water, The other plant I watered with regular tap water. Over a span of time I observed how these plants matured.Over my Spring Break the grey water plant grew. There was one thing that stood out and that was that my regular watered plant did not grow at all but that gave me fantastic results to record. I accumalated my water from all over my school. Some of the water was from the art room, our sinks, and other water projects. I did some research and found out that in a cup of water I used there was soap in it. That soap helped the plants grow with its nutrients. Even though this project took time it still, overall turned out to be a wonderful project that I think anyone would want to do because the results can sometimes startle you or amaze you, just as they did me. The tools that you need are not expensive, to do this project all you need is soil, bean seeds, and reused water,

=What type of soil cleans groundwater best? by Cort=

media type="custom" key="3590180"



My project is on what type of soil cleans groundwater best? MY result were the rocks and sand work best. While the sand got out most of the food coloring and the rocks got out most of the glitter and the clay didnt work at at all. I made the polluted water by mixing glitter and food coloring. *I got one cup and taped on top of another cup with holes in the bottom of the top cup then put the soil in the top cup then poured the water. As you can see in the photo above. I think the sand took out most of the food coloring because it stopped the minerals that were in it and took the coloring away from the food coloring but you would probably think that the sand would take away the glitter but it didnt stop much. The rocks took away the glitter because when the glitter got stuck in the spaces of the rocks and the food colouring just got through. Materials: Glitter rock sand clay cups food coloring

=Water Conservation= media type="custom" key="3681567" Hi my name is madison and i did my project on conservng water. First you take a pan, bowl, soap, sponge, and a plate. First you take the bowl and you fill it up with water and you see how many times it takes to fill the pan up with water. When the pan is full you take the soap and make the water all soapy. And then you take the plate and put it in the pan of water. you get the plate all soapy with the sponge and take the bowl and fill it up with water and see how many times it takes to get all the soap off the plate. And that is my project. By: Madison
