Water Filtration Experiment

Ahh The Water Cycle. Always a fun time to do a little hands on science. We decided to talk about filtration and how dirty water ends up clean. Another easy experiment that you probably have all the supplies for. At least, if you drink coffee. Which, I do now. I know. I’m really maturing nicely.

First we needed some dirty water. So we dumped some dirt from the yard into a flower vase filled 2/3 with water. Red solo cup! We’re ready to party!Water Pollution Experiment02

Then we gave it a good mix. Yes. He’s stirring with a pencil. We are incredibly high tech around these parts.

Set up your filtration system with a coffee filter, a funnel and an empty soda bottle (or whatever other clear container you have).

Then slowly pour in the dirty water.

And observe. Mine were far more intrigued with the gunk left behind.

Until they got the brilliant idea that they could double up the filters and do it again…and wondered if they could get the water even cleaner. Love the connections during hands on science!

They even busted out the magnifying glasses to get a super close look. You can mostly see the progression of our water here. Far back is the dirtiest, left a little tiny bit in the bottom of the soda bottle from the first filter and then the front vase is the triple filtered water. Is this how they make triple distilled vodka? Hmmmm.

    1. Thanks Traci! I love having a schoolroom. It impresses me greatly that so many homeschoolers do such amazing things without one!
