Water Filtration Unit Experiment

So many people get sick from their own drinking water.

Water filtration unit experiment. Decide if the water is a b or c grade and help them measure their sample in a graduated cylinder. To start ask the child to make a hypothesis or prediction about the experiment. You will need a few supplies. 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.

2 glass jars sand gravel 3 4 coffee filters dirty water a plastic cup with a hole cut in the bottom. Pour the water into the bottle with its top cut off. Once filtering is complete have them bring the test tubes to you for observation. Put the lid on the bottle and shake vigorously for 30 seconds.

Then pour the water back and forth between the two cups about 10 times. We went to a little pond nearby to collect some water. Again notice how the water looks and smells. Pour swamp water in the 2 liter bottle with a lid.

Notice how it looks and smells. Pour two glasses of water from the kitchen faucet. Once completed give each team 25 ml of the dirty water to begin to filter in their test tubes. For this experiment it is best to test the water before and after the filtration.

Begin by getting a jar full of dirty water. The second glass will be dirty dirty the dirty water with materials found around the house.
