We The experiment we conducted was to see if the school’s water was safe to drink. We tested our school water from different locations, a variety of dirty water, and bottled water. We tested the water for nitrate, chlorine, copper, iron, pH, and hardness. We found that our water was safe for iron, pH, nitrates, and chlorine. However we found that the unpleasant tested the water for nitrate, chlorine, copper, iron, pH, and hardness. We found that our water was safe for iron, pH, nitrates, and chlorine.

During our experiment, we had the same amount of strengths as our weaknesses. For example, we needed rain water when it During our experiment, we had the same amount of strengths as our weaknesses. For example, we needed rain water when it wasn’t raining. So we had to switch from rain water to other sources of dirty water. When we first started our experiment we observed wasn’t raining. So we had to switch from rain water to other sources of dirty water. When we first started our experiment we observed the water because some of it was a Smoky white color. We were concerned that our school water wasn’t healthy. First we the water because some of it was a Smoky white color. We were concerned that our school water wasn’t healthy. First we experimented the hardness of the water and we found out that our water was a little more harder than normal. The hardness of our experimented the hardness of the water and we found out that our water was a little more harder than normal. The hardness of our water is safe because we get minerals. Hard water can cause aesthetic problems. The level of copper in are water is high enough to water is safe because we get minerals. Hard water can cause aesthetic problems. The level of copper in are water is high enough to taste metallic but not high enough to kill you. When we tested iron but we were in the safety zone so it was safe to drink. taste metallic but not high enough to kill you. When we tested iron but we were in the safety zone so it was safe to drink.

Why does our water taste different if it’s safe to drink, because our water comes from a well. During our experiment we found that Why does our water taste different if it’s safe to drink, because our water comes from a well. During our experiment we found that everything was in the safe category. The water is still soapy, and we didn’t know why or what is causing the water to look and taste everything was in the safe category. The water is still soapy, and we didn’t know why or what is causing the water to look and taste that way. While doing the experiment we though more about ideas that we didn’t research about. We thought about if the school water that way. While doing the experiment we though more about ideas that we didn’t research about. We thought about if the school water is safe to drink, then why does it taste different than bottled water, but our data didn’t support this question.is safe to drink, then why does it taste different than bottled water, but our data didn’t support this question.

The purpose of our Team Science project was to see if our school water is cleaner then rain water. Our school, The purpose of our Team Science project was to see if our school water is cleaner then rain water. Our school,

Jefferson School, gets its water from a well. We thought our school water was unclean because it was cloudy looking Jefferson School, gets its water from a well. We thought our school water was unclean because it was cloudy looking and sometimes it tastes different. During this experiment we found out that Tracy (CA) gets it water from the central and sometimes it tastes different. During this experiment we found out that Tracy (CA) gets it water from the central

Water from the ground gets treated, as the water pump, pumps water from the ground, the pump has chemicals in it Water from the ground gets treated, as the water pump, pumps water from the ground, the pump has chemicals in it that help remove contaminates, sometimes they chlorinate it. They do this if they believe there is a bacterial or that help remove contaminates, sometimes they chlorinate it. They do this if they believe there is a bacterial or

parasitic infection. To see if the water is contaminated. We tested: Total Iron, pH, Copper, Hardness, Chlorination and parasitic infection. To see if the water is contaminated. We tested: Total Iron, pH, Copper, Hardness, Chlorination and Nitrate. Our original hypothesis was, “If we tested rain water, bottled water, and our school water, then bottled water Nitrate. Our original hypothesis was, “If we tested rain water, bottled water, and our school water, then bottled water would be cleaner because the bottled water is actually distributed in the United States.” During our experiment, our would be cleaner because the bottled water is actually distributed in the United States.” During our experiment, our independent variable was the different water we used at various locations, and our dependent variable was what we independent variable was the different water we used at various locations, and our dependent variable was what we

measured. We also tested dirty water to use as a baseline to compare with bottled water. (Ex. Total iron, chlorine, PH measured. We also tested dirty water to use as a baseline to compare with bottled water. (Ex. Total iron, chlorine, PH etc.)etc.)
