A human body study would not be complete without covering the reproductive system. During the past year we began our human body unit study with cells and progressed through the body covering the digestive system, the nervous system, liver, spleen, circulatory system and so much more. Kids are naturally curious about reproduction and incorporating the topic as part of the human body study seemed natural.
Reproduction is a highly personal topic especially in regards to what we tell our kids. In our house we have been honest and answered all of the very detailed kid questions. Therefore, before beginning this lesson the kids had a good understanding of reproduction. In fact, the two oldest kids witnessed their sister's birth.
From our prior discussions the kids knew that daddies put babies into mommies bellies with their penis. When sperm go in they search for an egg inside the mommy. Mommies have three holes; one for urine, one for feces and one for babies. Daddies have two holes; one for feces and the other is for urine and sperm. Babies go in and out through the same hole. Daddies get to decide when babies go in, but mommies have to say it's alright.
All the kids knew was discussed mostly in the car over the course of several years and through many questions............ (I'm taking a deep breath.)
The reproductive system is the only human body system that takes a boy and a girl to make it work. All the other systems are contained within our bodies. I taught this lesson much like my numerous other human body lessons. We made a model using craft supplies and household items and talked about what the model represented and how the body worked.
First we made simple models of boy parts and girl parts.
The red liquid (water with red food coloring) represented blood. The plastic bag was the uterus. Two yellow straws were stuck into the plastic bag near the top and represented the fallopian tubes and the pink straw at the bottom was taped into a hole in the bag and represented the vagina. There was also a bowl of tiny beads to represent the eggs (not pictured above, but can be seen below).
The two glasses of yellow liquid (water and yellow food coloring) represented the testes. The syringe represented the penis.
This project turned out to be a very relaxed way to talk about an uncomfortable subject. As they get older we will begin to talk about STD's and other related topics, but I think this is definitely enough for now. The activity raised a few more questions, but it answered many more than it raised. My favorite quote came from my six year old daughter at the end; "I don't like the girl part. It's messy." If she only knew how insightful she was.
If you've made it this far, thank you for reading about our reproduction activity. I hope you enjoyed it and didn't find it too uncomfortable.
This is the last post in our human body unit, but there is much more science to come. Over the next few weeks I have some Astronomy posts planned and then will be moving onto Earth Science.
