Saltwater is the softest

Hey!?! Saltwater is the softest? You mean it outdoes distilled, bottled and tap water? But, it has so many minerals in it!?! Yep, you kids tested it and all seem to agree, saltwater provided the most suds in testing.

Is There A Secret?
Yup. The ions in salt actually attract minerals in water and sort of neutralizes the minerals, making the water soft. If you really wanna know. That water softener some of you have for your wells, uses rock salt to soften the water. When we get to Activity 5, you will learn all about it.

Don't Forget
Those of you working on your bar graph have to remember the "Y" axis has to be identified. You just can write 1mm, 2mm, 3mm. . . Those numbers have to be labeled as "Measured Height of Suds," or something like that. And the "X" axis is not just distilled water, tap water. . . These are water samples used.

Joining Tonight
I have been invited to join the Northcentral Chapter 8 of the Society for Pennsylvania Archaeology. They meet tonight at the Taber Museum on West Fourth Street. I am excited about this organization since I have a severe love of the history of our valley. I'll let you know, tomorrow, how the meeting went.

Have a great night.

Hi Mr. Z!!
Thanks for the reminder about the x and y axis. That Taber Museum thing sounds interesting. My dad and I love to go there. He has an article from a long time ago displayed there. It was from when he was an intern at the Sun-Gazette.
