Water, water everywhere...is it safe to drink?

Yesterday in the afternoon we got to go down to the river, which I don’t know how to spell. First, we did some physical tests on the water. After observing it we said it looked good. During this process we were distracted by a lot of frogs including one poison dart frog.

Second, we did some chemical tests on the river to see if it was safe to go rafting in. We tested the temperature, pH, Nitrate, Carbon Dioxide, Oxygen, and Hydrogen Sulfides. After testing these six things our data concluded that the water was safe to swim in chemically.

Finally, we did a biological test by catching bugs. When we caught as many bugs as we could we used a scientific equation to calculate if the river was good biologically. It fell into the category saying the river was good but not great. Time for white-water rafting!

  2. Hi Connor and everyone:

    I agree with RobinMags... That's amazing that you performed all those tests and I'm sure it helped you appreciate clean water which we sort of take for granted here in the States. I hope you had an amazing time white-water rafting... I've never gotten to do that! Did anyone get a picture of the poison dart frog? Megsie... anyone!? I'm curious to know what color it was.

    Thank you for taking the time to post this blog... I'm sure you're all tired but we're really excited to hear all about your adventures so keep them coming!

    Looks like you are using some of the physical science that you learned in 6th grade!

    Have fun! Senora Jordan

  5. Hey Connor its Peter I hope you are having fun at Costa Rica. Monsters vs Aliens was really funny. I've missed you so much. I remembered this year during a field trip we had to test the river's pH to see if the river was healthy.Maddie says hi. I hope you have a good time!
