1. Through this project what did you learn about chemistry? I learned that there are many different ways to purify water.i also learened that chemistry takes a lot of work decause you cant have any contaminants because the reading you get may be wrong.
2. Through this project what did you learn about designing and carrying out an experiment? i learned that designig an expiriment is hared work because you have to find out different things like has any one done this expiriment befor. you alsow have to find out what your variables are. you also need to know what you are doing. i did not know that to test for conductivity the water i was testing had to be the same temp.
3. Through this project what did you learn about yourself? I earned that i am able to do the work that is given to me.
4. If you had it do do over, what would you do differently? i would test more samples of the same brand of water because . i would also test to see if the minirals in the water are safe or if they are good for your body.

1. What does your data say about the quality of your water? Were any parameters higher than others? If so, what does this mean (possible contamination sources)?the data says that my water is safe to drink.
2. What does the class data say about the quality of drinking water in this area? the class data  says that the quality of drinking water in our area is good because the pH average was 7.6.

3. What does the class data say about the quality of stream water in this area? the class data says that the quality of water for this area is good almost every ones water was safe. 
4. Which sites stood out to you as being most natural or most influenced by human activity? site 2 stood out because the water there was not safe the  ph average was 9.2.

5. How confident are you in the reliability of our data?        I am not confident with the reliability of our data because some of the probes may not have been calibrated right.

6. What questions do you still have about the quality of water in our area?

what is the state doing about water quality?

what can we do about the water quality in our homes?

“helium is actually used in neon signs.”
” Helium is used to cool superconducting magnets.”

helium is used in ballons and in some air craft.

Helium -272.[C] melting -268.9[C] boiling point

helium is a gas.

Electrical conductivity: S cm^-1

• Fun Facts:
• helium was discovered by a french astronomer  Pierrre Jannssen.
• “1/4 of the mass in the Univers is made up of helium Atoms.”
• helium is mixed with oxygen to be used for deep sea diving.
