This experiment is for advanced students.Have you ever taken a gulp of the ocean? Seawater can be extremely salty! There are large quantities of salt dissolved into the water as it rolled across the land and into the sea. Drinking ocean water will actually make you thirstier (think of eating a lot of pretzels). So what can you do if you’re deserted on an island with only your chemistry set?
Let me show you how to take the salt out of water with this easy setup.

Sorry for the confusion! When you go through the program by Grade Level instead of by Topic, please request the grade level you’d like unlocked for you. This is a newer area of the program and at this time, we still need to manually unlock the grade levels you request in order to give you access to the content. Thank you! I will have Tonya connect with you!
I clicked on 5th Grade Earth Science and it had this lab of Taking the salt out of the ocean, but when we clicked on it, it said it was advanced. I thought I was in the fifth grade curriculum.
