After so many biology classes, I had begun to realize that it seemed as though I spent a lot of time and energy teaching my kids all about cells, only to have them forget at least half of what they learned by the time we approached cell division, photosynthesis, cellular respiration, etc.
It was one year during the last class of the day, my beloved “G” period. There were 10 students in that class (long, crazy story there– maybe I’ll write about it and get a link in there so you can read it!), and it was a glorious class. It ended up being my favorite class because it was so easy to differentiate. It was so easy for kids to help others out. It was so easy to teach. (Is that an oxymoron?) Relatively speaking, that is, it was easier to teach than classes of 30. And it was more rewarding, because the kids really understood and tended to do better on their tests than the other classes. And there we were, talking about cellular respiration when one student, a bright student, chimed in and asked
“Ms. J., what is a mitochondrion?”
No big deal, I thought. And I answered him. It’s a singular form of mitochondria. He nodded, his pencil at his lips, looking down at his graphic organizer we were doing at the time.
Me: “A-and it’s where cellular respiration occurs.”
Student: “OK, so it’s in the cell.”
Me: “Yes? Yes.”
Other student: “What’s a mitochondria?”
Everyone laughs. But this year, I wasn’t laughing. This was something that I could see happening in many of my classes, even if students didn’t speak up. These big words were coming back to them and they had already been learned- and lost. So, I popped my lap top into the in-focus and brought up my Cell PowerPoint. Remember this? They did… vaguely.
That’s when I had an idea… if only I could have a cell in the classroom always. And not just a poster, but an interactive cell that could grow and change.
