The past few weeks we have been working on our body. The circulatory, respiratory and reproductive system have been explained in class and a little review of the digestive s (digestive system is not necessary to develop at the project).

Your children have a project for next Thursday November 5th. As I explained last Monday at class they must make several group minimum 3 people each. In each group the 3 systems must be exposed with the aid of visual materials. That means they will explain each system orally. They will share different tasks, it is not mandatory to meet at any house just they have to divide the work and do their job individually

Examples of circulatory

Examples of repiratory system:

Reproductive: This project is great to understand how te reproductive system works

A human body study would not be complete without covering the reproductive system.  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.

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.

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).

Boy Parts
The two glasses of yellow liquid (water and yellow food coloring) represented the testes. The syringe represented the penis.

The girls handled the girl parts and my son took care of the boy parts. The girls had a lot to do. We began with a uterus full of blood and then began counting. (1-28 to represent a 28 day cycle.)

As we counted from 1 to 5 the blood was drained from the uterus (menstruation).

We continued counting. At 14, a small bead (egg) was placed into one of the straws (fallopian tubes) which traveled to the plastic bag (uterus). Red water (blood) filled the uterus as we counted from 15 to 28.

No fertilization took place. We began counting again from 1 to 5 blood while blood and the egg drained from the uterus.

Up to this point my son did not have any tasks, but kept himself busy playing.

Finally we told him it was time. At 14 another egg traveled down the fallopian tube and he was able to add some yellow water (sperm) to the uterus.

I told the kids that if the water turned orange they would get a baby, because that meant that the sperm had found the egg.

So he put in yellow water several times and the girls wanted him to.

They got a baby and the girls wondered how it was going to fit through the straw. I told them that normally it stretches, but they would have to put a hole into the plastic bag (uterus) to get it out. We didn't talk about c-sections, but it would have been a good opportunity.

They got a baby bird?

This project turned out to be a very relaxed way to talk about an uncomfortable subject.
