After doing a gallery walk with students' ideas regarding what's happening on the cellular level, Mrs. Brinza was able to find some neat videos of cells doing something incredible!
Without a doubt, we absolutely saw that one cell became two cells...we called it dividing, regenerating, and splitting in class. We also are seeing that the two cells that come from one cell look just like the cell before it, so the new cells that are made are identical to one another.
We're curious how this process happens, because we know enough about matter and energy now in 6th grade, that if the two new cells came from the other cell, and they're the same size, that something had to have gotten into the cell in order for it to become bigger. But how exactly does that happen? And where does what goes inside the cell come from? The blood carries stuff...is that it? We know the blood carries food particles! Do cells eat? They don't have mouths--wait, or do they?
And aren't there single-celled organisms, too? Like bacteria? We've heard a lot about bacteria and viruses over the last year. Maybe we can investigate them to help us how new cells are made in the healing process!
