Homemade Salt Water Experiment

This article, entitled Homeschool Salt Experiment, comes from Dawn Wells at Blogging Mom of 4.

A recent homeschool science lesson discussed oceans and saltwater. There was a great, quick experiment at the end of the lesson.

The lesson was talking about how water leaves the ocean by evaporation. As it evaporates, it leaves the salt behind. In every hundred pounds of seawater, there are at least two pounds of salt. This experiment will demonstrate the evaporation process.

We tend to take pictures of almost everything we do now a days because it might be something I want to blog about.

I thought I would share it with you all in case you wanted to try this with your kids. My kids thought it was a neat experiment. I guess one of them more than the other. Caleb was around for the end of the experiment but didn’t stick around for the process. Faith, on the other hand, was right up on the counter helping me measure, cook, etc. She jumped right in.

Homeschool Salt Experiment

What you’ll need:

4 T salt
1 C water
cooking pot
stove
an adult to help

What to do:

1. Add salt to cup of water. Stir until you have dissolved the salt in the water.

2. Pour salt water into pot and heat to boiling.
The water in the pot becomes steam or water vapor and begins to disappear into the air.

3. After all the water has evaporated, measure the salt to see how much salt is left.

This is a quick and easy experiment that doesn’t explode in your house and is something visual for your kids to see. Of course, make sure to supervise the whole time. I even let the kids place their hands a safe distance above the steam so that they could feel the vapor rising…their hands would get damp and they’d say that they’re hand was sweating.
