How do you know if something is alive? Check out the super goofy "biology song". It's a classic!
Last Tuesday we started talking about life on Earth, how it might have started, and what it looks like now.
We talked about the smallest life forms: one-celled organisms like this bacterium.
We also discussed the very cells that make us who we are, like this animal cell.
And then, we made animal cell models, with jello representing the cytoplasm and candy representing the different organelles.
Of course they had to taste the organelles...
And, as usual, there was time for some spontaneous tepee building.
Tepee to be continued...
