The denser the media the less airflow through it.
That depends on the density of the media and the type of wave.
Water changes are the only way to have an immediate effect. If you can get some used filter media from someone and add that to your filter it will help speed the 'cycling' up.
A media change involves changing out the 'stuff'(media) inside your filter. Changing carbon, fine filter pads, cleaning sponges, and rinsing biological media are all examples of media change in an aquarium.

There are many different filter media commercially available. They range from fine fibrous wool type media through activated charcoal which both need to be replaced regularly to the various ceramic noodles and filter sponges that can be rinsed and reused many times. I prefer to use a mixture (layers) of several types of media including all the above in a power filter.
its a filter that blows air into the water you can usually get them at your local pet store
true
If you have a power filter it should come with the required filter media. Firstly follow the directions on how to position the filter and where to place the media. If the aquarium is a planted one there is no need to do much other than turn it on because the plants will have some good aerobic bacteria that will end up lodged in the filter media where you want it. If the tank is a bare tank you will need to cycle the filter either by adding some old but freshly used filter media or purchasing some filter cycling bacteria at a pet shop. There is another more complicated method using Ammonia but I won't go into that here. If the filter is air as opposed to power driven, you can use whatever filter media is recommended by the pet shop and use the above techniques to cycle it.
what are the positive effects of media on child psychology
Most likely, no. The filter media (paper) inside the oil filter may not be compatible with fuel.
Your filter will tell you on the side of it how much media sand to put in it.
