Witchlette has been functioning with biological terms for body parts for both males and females. She has been working with the metaphor for human reproduction that a dad has a seed that he gives to a mom, which she puts into her egg.
We have talked about how some families that have two dads use an egg from someone else and one of their own seeds. Likewise, families with two moms use a seed from someone else and one of their own eggs. Sometimes a mom doesn’t have eggs of her own and uses another woman’s egg. Same goes with a dad and his seed.
“But how does it work?”
It’s not a sunflower seed and a chicken egg. Those are two terms used to describe microscopic cells that come together to make new life. They get put together and the two microscopic cells divide into two cells. Those each divide into four. Each of those divides and now there’s 8. And so on. They divide, and grow, and specialize to make all of our body parts and body systems.
“How do they get together? How does it work?”
I put it off as long as I could. I gave you biology, but I’m not ready for mechanics. I don’t know if you’re actually ready for mechanics yet.
The next day, from seemingly out of no where, “I’m so glad I’m your daughter. I love you so much Mommy…Can you please teach me how the egg and seed work?”
I found a 3d animation, that seems like something out of my own high school health class.
“Fertilization is human reproduction through sexual intercourse”.
No questions about what is sexual intercourse. Ok.
Sperm swim across the screen.
So, those are the seeds. The biological word for them is sperm. The metaphor is seed.
“The sperm swim through the cervix…”
“So, they go in the belly button?”
That’s not the belly button.
“Here a large number of the sperm die.”
“Why do they die?”
Because only one will get to the egg, and that one seed, I mean sperm, and one egg make one baby.
That’s the egg
“That’s not an egg…”
Most people, even scientists call it an egg. Biology books will also call it an ovum. Ovum is the true scientific name.
“The tightly wrapped genetic material from the sperm unravels and prepares to pair up with the genetic material from the egg”
“Wow! That’s DNA?! So that’s how it works!”
Biology for the win.
I’ve still got at least two years before we have the discussion of mechanics.
