A snapshot of our school day during quarantine.
Simultaneously Sam is working on a virtual lesson, Lilly is in a video conference with her class, and Christine teaches in the background.
This is what school is like now. We are all doing the best we can. Hang in there. We’ll get through this.
Since setting up the jar aquarium two weeks ago the water level in the jar has been rising. I removed water multiple times to lower it back but it kept overflowing which had me very befuddled last week. I even marked the neck of the bottle with the height of the water at different times of the day. The water does go up when the sun warms the bottle, but it does not return to the starting point the next morning. It slowly continues to rise.
But I think I finally figured out the cause. Can you see it in the image below?
Bubbles. There is a large amount of gas trapped beneath the mud. These bubbles are created during the process that is breaking down the decaying plant life within the muck. The process probably goes faster when the sun hits warms the muck.
In the image above you can also see the tunnels that the worms have been making in the mud. I haven’t been able to capture a good photo of them.
I gave the bottle a good jolt and tons of bubbles streamed to the surface. Releasing the built up gas lowered the water level nearly back to its starting point.
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!
I filled a one gallon jug one-third full of muck from the swamp then filled the rest with the swamp water and added some aquatic plants for good measure. When I was done it looked like this:
After twenty-four hours the water had cleared up a lot and now looked like this:
There’s even a few critters swimming around the top:
I’m hoping it will clear up even more this week and the plants will start to grow to create a self-sufficient ecosystem.
You’ve got snots by the lots
And snoogies and boogies
You’re nose is all rosie
You’re feeling all woozie
You’ve come down with a cold
You’re of age now my child
You’ve been to the breeding grounds
Where great germs roam wild
Day care and the doctor’s
The mall food court’s bathroom
you tasted everything
and licked a baboon
So now you are soggy
crusted cranky and crabby
there’ll be no sleep for you
(‘nor for mommy and daddy)
But fear not my child
for some future day
you’ll return to good humor
and go out to play
Sam is sick so I wrote this poem for him with a suggestion from a friend.
