It depends on if you're trying to create something, or if you just want to do some kind of demonstration.
If you have the money, you can look at conditions for beneficial bacteria growth in sponge filters using varying methods. This lets you create a fantastic display explaining the nitrogen cycle and its effect on fish care, plus your experience with, say, 3 different sponge filters cycling in different buckets or aquariums. They would need to be kept in identical conditions, and right next to each other. Every factor, including sunlight, would need to be taken into account.
What I would do would be demo cycling lengths with 3 methods:
b) using fish food, and
c) using pure ammonia.
Keep the temperature and sunlight in each vessel identical. Ideally, place them all in a row. Use heaters, if you use a betta - or without heaters if you wanted to use a baby goldfish...as long, of course, as you had a plan to rehome or give the goldfish proper housing at the end.
There'd be a bit of cost in the setup, so that depends on your family and your resources.
The whole project has the added benefit of educating anyone interested in one very important aspect of fish care. You could include in your display information on what overfeeding is and why it pollutes the water, how to do a water test, and the effects of ammonia exposure on fish.
I exist to compile, assimilate, categorize, and disseminate information. The day I stop learning is the day I stop breathing.
