Water Filter Science Project for Kids

This water filter experiment is a fun and simple  Science Project for kids

What are Water Filters and What do they do?

Water filters are used to remove impurities and solid particles from our water. They make our drinking water clean.

Follow the steps below to make your own home made water filter.


Materials needed: Pitcher of Water half full, Glass Jar, Coffee Filter, Cup of Soil/Dirt and a Funnel ( I cut off the top part of a soda bottle and turned it upside down to make funnel)


Step 1:  Have child collect a cup of soil or dirt.

Step 2:  Place the funnel in the glass jar and place the coffee filter in the funnel






Step 3: Mix the soil with the water together in a cup

Step 4: Slowly pour mixture into funnel, wait until water drains to add more






Step 5: Watch what happens!






What Happened?

The water the flows into the jar will appear much cleaner.

How did this happen?

The coffee filter acts like a water filter and catches the soil/dirt particles and separates them from the water.  The clean water drips down into the jar.

You did it, you made your own home made water filter! Now enter it in your school Science Fair!
