“Running Desalinization Plants,” p. 103March 9, 2011Objective: You will be able to
scientifically test your solution to a technological problem.
Do Now: What are 2 phase changes that you hope to happen in your desalinization plant? Where will each of them happen?

Test Your Desalinization Plants Send one volunteer to get a cup of ice. Send one volunteer to get your
desalinization plant. Bring it to me and I will carefully pour in salt water.
Work with your group to set up your desalinization plant.
We will put them on the hot plate at the same time…
![Page 4: Welcome Back! Open your binder to your table of contents. Have a SHARPENED pencil in your hand.…](https://reader035.fdocuments.in/reader035/viewer/2022070616/5a4d1bdc7f8b9ab0599dd0e1/html5/thumbnails/4.jpg)
Using the Hot Plates If you are anywhere near the hot plate,
you must wear goggles! Seriously! Anyone who touches the hot plate
MUST be wearing oven mitts. The WHOLE hot plate (even the white
part) AND the can will get hot. Set the hot plate to MEDIUM.

While Your Plant is Running… Work on the Chemistry Connections
sheet with your group… it will help you with our quiz on Friday.
If you want, you can send one volunteer at a time to check on your plant.
That volunteer must wear oven mitts! BE CAREFUL OF STEAM! STEAM CAN BURN!!

Let’s Check Out our Plants BE CAREFUL OF STEAM! STEAM CAN BURN!! Anyone who touches the foil MUST
wear oven mitts! Don’t forget your goggles!

Turn Off the Plants (15 min left) Send one volunteer to turn off the hot
plates. This will let them cool.

Salt dissolves into rivers from landSome ocean water evaporates to atmosphere
Water vapor CONDENSES into a cloud!
Precipitation!
Now the ocean is a LITTLE bit salty, but no saltier than a river. How does it get really salty?

Let’s Find the Winner Work with your group to pour the
treated water into a graduated cylinder.
Be ready to hand it to me as I test its conductivity.
If the green light doesn’t turn on, it is desalinized!

Share if time… What were the most
successful parts of the desalinization plants?
