Pour two glasses of water from the kitchen faucet.
Water filtration unit experiment.
Notice how it looks and smells.
Begin by getting a jar full of dirty water.
So many people get sick from their own drinking water.
Put the lid on the bottle and shake vigorously for 30 seconds.
The first glass will serve as the control.
How to do the water filtration experiment.
To meet this challenge students use an iterative process as they build test and measure the performance of the filtration device analyze the data collected and use this information to work toward an improved.
Then pour the water back and forth between the two cups about 10 times.
You will need a few supplies.
Once completed give each team 25 ml of the dirty water to begin to filter in their test tubes.
To start ask the child to make a hypothesis or prediction about the experiment.
Once filtering is complete have them bring the test tubes to you for observation.
Decide if the water is a b or c grade and help them measure their sample in a graduated cylinder.
For this experiment it is best to test the water before and after the filtration.
We went to a little pond nearby to collect some water.
Pour the water into the bottle with its top cut off.
Pour swamp water in the 2 liter bottle with a lid.
In this activity students are challenged to design and build a water filtration device using commonly available materials following the same design process used by the engineers and scientists who developed the international space station water recovery system for nasa.
