Answers
Materials
Plastic soda or juice bottle
Vase or tall drinking glass
Gravel or small stones
Clean Sand
Activated Charcoal
Cotton balls, small cloth or coffee filter
Gardening dirt
Water
Scissors or knife
Instructions
Cut off the bottom of an old plastic soda or juice bottle using scissors or a knife.
Place the bottle upside down into the vase or tall drinking glass.
Place cotton balls, cloth, or a coffee filter inside the bottle as the first layer. The first layer should be about one to two inches thick.
Add an inch of activated charcoal as the second layer on top of the cotton layer.
Over the charcoal, add about two inches of gravel or small stones as the third layer.
Add about three to four inches of clean sand on top of the gravel.
Add gravel to the bottle as the final layer. Leave about a half inch of space from the top of the upside down bottle.
Add dirt to a glass of water to create muddy water. Alternatively, get creative and add other things like glitter, beads, cooking oil or other materials to make dirty water.
Pour the glass of muddy water on top of the homemade water filter and watch the water drip clean into the glass below.
How to Test the Water
Homemade Water Filter
For this experiment, it is best to test the water before and after the filtration.
To start, ask the child to make a hypothesis or prediction about the experiment.
Pour two glasses of water from the kitchen faucet. The first glass will serve as the control. The second glass will be "dirty."
Dirty the "dirty" water with materials found around the house. The "dirty" water can contain things like dirt, potting soil, glitter, dish detergent, kitchen oils, among other materials found around the house.
Have the children test the two glasses of water with a home drinking water test kit, like the First Alert Drinking Water Test Kit.
Answer:
A DIY water filter can give you water that's safe to drink — no matter where you are. Using a water filter can be a great way to ensure harmful contaminants have been removed from your drinking water. You can find them available for purchase in a wide variety of styles at many different prices.
