Collecting Salt from Salt Water

One of the first activities we did to go along with the book How to Make and Apple Pie and See the World was to get salt out of saltwater.  I suppose we could have just boiled it dry, but I decided to take a different approach.

 First I had the girls add salt to the water and see that it disappears (dissolves).

To get it back out We prepared a bowl with clay in the bottom and popsicle sticks sticking up (I wanted skewers, but apparently I'm out). Then we poured in the salt water we made. And waited overnight.

The next morning this is what we found. Look close, and you can see some crusty stuff above the water on the popsicle sticks....salt!

This was a pretty easy little experiment, and only the first of several activities we did along with this book. Be on the look out for more!
