Experiment ~ Can You Undo Water Pollution?

In this experiment the kids learned just how hard it is to undo water pollution.

We grabbed a bucket of clean water, some household trash, vegetable oil (to stand for toxic oil spills), tongs, and a strainer.

The kids took turns adding trash to the water.

After our water was yucky enough

they tried to remove all of the pollution using tongs and a strainer.

Emily even tried to scoop up the little pieces of trash and dirt with her hands.

After 15 minutes of trying to remove all of the pollutants, we were left with a pile of trash and water that was still oily and dirty.

The conclusion ~ It is impossible to remove all of the pollutants from the water.

To go along with our experiment we read Oil Spill! by Melvin BergerOil Spill! (Soar to success)

and Where Does the Garbage Go? by Paul Showers.  Where Does the Garbage Go?: Revised Edition (Let's-Read-and-Find-Out Science 2)

Tomorrow we are going to decorate a compost container to keep in the kitchen and some new recycling bins.

That is way too cool! My kids would love to do this. If you're willing I'd love if you would link this up to my Science Sunday post this Sunday.

WOW, That's very good. You do the coolest things!
Thank you for your comment on my blog. Means so much to me :)

Excellent, excellent study - I loved this so much!

I am going to try this with Jordan today!

Yes, it is true that there is no way to undo pollution. It seems to ring to the cliche "damaged is done". However, as technology develops, there are also some procedures introduced to somehow clean dirty water.

Our company uses stormwater systems to filter rainwater and reuse it. It makes acid rain reached its normal ph and make it possible for human use. Who knows, in the next decades men can also invent something that can turn a totally polluted water clean.

This is adorable and sweet! Did they learn something from it? If it was a long time ago, you think they still recall the lesson to be learned?

Just saw this on Pinterest and had to stop by. I am so impressed with this activity. I am an Environmental Science major and love teaching my children ways they can help make a difference. This is one activity we must try! I would be curious to try filling a knee high stocking with hair as they did during the gulf spills and seeing what effect that had on the water. So cool! really, thank you!

Hi Cindy,

We loved this hands-on exploration of pollution and featured your activity in our Earth Day showcase over at Preschool Lesson Plan!

You can find the full feature here:
http://preschoollessonplans.info/2005/earth-day-experiment-can-you-undo-water-pollution/

We were sure to give idea/photo credit, as well as a link back to your blog, but we'd love for you to check it out!

Have a wonderful day,
Kayla

We all can help prevent water pollution. Governments have laws that cover pollution by industry, but many of the things people do every day contribute to the problem.

This is such a great project. I shared it on my website which is a collection of ideas for scout troops. I linked back to your project page. THANK YOU!

I certainly approve of the purpose of this activity. It is really impossible to remove all of the pollutants in the water. Although technological advancement has introduced ways to clean dirty water, still it cannot be restored into its clean and original state. This activity is very educational; it can instill in the child’s mind the importance of caring for the environment. I hope many parents will do this kinds of activities with their kids, and it will surely enlighten them.

Scientists should spend a little less time trying to predict when we'll die, and a little more time trying to delay or prevent it from happening.

Thank you so much for sharing this activity. My kids are going to love it! I just put the books recommended on hold at the library too. Can't wait to see how it all goes!

Chrissy @ The Outlaw Mom Blog said...

This is such a great way of sharing an important lesson - love it! And thanks for the book recommendations, too. Found your post through Jamie's roundup of Top 10 Water Experiments :-)

Christine said...

That's awesome! To give them a further sense empowerment and knowledge on the topic (maybe 5th or 6 grade). It would be great to show the kids that over time, with Bio Filtration ( plants and soil), the water can be cleaned! :-)
