Process - ( use verbs or doing words in each step )
Step 1
Cut the bottle in half.
Step 2
Put the top half upside down inside the bottle.
STEP 3
Add layers of filter paper then add your sand/pebbles.
STEP 4
Get 1 cup of dirty water.
STEP 5
Pour dirty water into the upside down bottle/funnel.
Measurements
After we finished our experiment our water was still dirty, maybe next time we could put less sand to the filter paper so it won't go to the gap of the bottle/funnel.
Warning
Make sure that an adult cuts the bottle in half. This water filter is just an experiment and should not be used for drinking water.
Avoid using charcoal briquets, as these can contain chemicals you don't want in your water. Use the activated carbon for water purifiers instead.
