After one week the water in the jar aquarium has cleared up and now you can see everything that happens with the jar. Which isn’t much. The tiny insects that were swimming around the top of the jar seemed to have died off. There is still one worm that I suspect is really a leech.
It remains to be seen if the plants will continue to grow. Some of them are starting to look a little brown.
But despite lack of life, the jar aquarium does still have something I’ve been watching daily. There’s a mystery to the jar that I’m trying to solve. The water level keeps rising.
At first I thought it was just heat expansion. The jar does get some direct sun. But the water doesn’t seem to move much during the day. After reducing the water back down to its original levels three times and then finding that the water had again risen to the top of the jar I’m not sure what is going on.
We all know about the Conservation of Mass right? Matter cannot be created or destroyed it just changes form. I expected some movement due to heat expansion, but I thought it would go up and down with the temperature. I also expected all the plants and dead stuff in the mud to create methane and other gases that would bubble up. So far, no gas bubbles, but the water keeps rising. Something within the jar is increasing in volume. Could it really be just the water heating up?
What do you think? Put your ideas in the comments!
