Today in Science we created our own filters! This is a fun experiment, and easy to replicate at home!
First, we cut the top off of the plastic bottle to create our filter.
Then, we put a coffee filter inside. You could also use gauze and wrap it around the nozzle with a rubber band.
For our next layer, we put in cotton. This will help catch the finer particles of soil. You could also use sand for this step.
Finally, you can add rocks and charcoal to catch the large chunks of soil!
Now the fun part! Get some mud, and add some water!
Look, we’ve made a mixture!
Finally, add your muddy water into your filter, and watch how the water changes!
Let’s see what happens over the next few days! Thank you to everyone who brought in a plastic bottle, and some rocks!
