Today, after doing school, we got the supplies for Bethany’s science lab. I made everyone do it because, well, why not?
The lab is pretty simple, but the reaction of the liver to the hydrogen peroxide was pretty cool.
Also, lighting matches with the oxygen gas being given off was cool too…
which led to lighting matches just for fun.
Which led to Hannah asking why toothpicks don’t light from the match books. I asked her if she thought the toothpick was the same as a match – one is wood and one is paper, but they both burn. She looked at the matches and thought that the stuff on the match must have something to do with why matches light when you rub them on the cover and toothpicks don’t. The chicken liver that we used bubbled up so much that it kept overflowing the test tube.
It was fun to listen to the pop of the toothpick relighting when it got near the bubbles from the liver. Hannah’s piece produced some nice popping sounds.
The same experiment with apple, potato, onion and carrot wasn’t as neat.
The potato and onion foamed up, but didn’t light a glowing match. The apple and carrot did practically nothing. You can find one version of the lab here
Doing laundry and cleaning up liver fluid overflows took up the rest of my day. Next week it’s a photosynthesis lab, that one shouldn’t be as gross.
