Make A Water Filter Science Experiment
In this fun and easy water science experiment, we’re going to make a water filter.
- Two baking pans
- Empty two liter bottle
- Medium sized flower pot
- Coffee filter
- Put the coffee filter into the flower pot.
- Put about two inches of pebbles into the bottom of the flower pot.
- Pour sand into the pot until it is about three quarters full.
- Use your funnel to add about a cup of dirt to your two liter soda bottle.
- Fill the bottle nearly full with water.
- Put on the cap and shake the bottle to mix the soil and water.
- Pour some of the muddy water into one of the pans.
- Now set the flower pot in the other pan.
- Slowly pour the muddy water into the flower pot and observe the water that comes out into pan.
- The water will not be very clear at first. Keep working the water through your filter system and compare it to your control sample of muddy water.
How it Works:
The pebbles and sand act as a natural filter and will help purify the water.
Make This A Science Project:
Try adding food coloring to the water. Try different amounts of pebbles and sand.
