Thank you Tom Kiehfuss, 5th grade, San Pedro: "I have found this website from Sonoma County Water Agency very helpful in supporting the iTEAMS water theme this year. The students and I have done the drip sculpture activity and this week we will be building a solar water purifier and learning how to use our water testing kit. We will test and record salinity levels of water from the bay before we put it in our solar water purifier and then we will test the purified water once it’s gone through the purification process. We will also be using this data to share and compare with our science pen pals in Louisiana."
Focus:
Understand water seeping through porous rock and cracks carries dissolved minerals. As the water drips from the ceiling of a cave, some of it evaporates and leaves behind a mineral deposit in the form of a stalactite. Water that drips onto the floor of a cave also evaporates, and this mineral deposit forms a stalagmite. Stalagmites and stalactites grow very slowly; this activity allows students to witness model formations over the course of just a few day Challenge: Can you create stalactite and stalagmite formations in a much shorter time?

I am thrilled that Tom is working nationally with students in Louisiana on this project, as the data alone should do the majority of the teaching!

This looks like a lot of fun for the kids. I am wondering if you have a lab write up to go along with this. Is this an activity or is it more of a "formal" experiment?

Hey Josh, It was fun for the kids. I don't have a formal write up for the lesson but I did create an activity worksheet for the students that you are welcome to use. Let me know and I will send it to you.
