Expert Lecture #6

This time Jonah’s mom came in to talk about genetics. she talked about chromosomes and marking about genetics. In the end, she also gave us some books we could read about the topic. I had a really fun time!

Your gender is determined by chromosomes, one from your dad, and one from you mom. A male’s chromosomes is made up of one X chromosome and one Y chromosome. On the other hand, females have 2 X chromosomes, and no Y chromosomes. Your mom will definitely give you an X chromosome, while you dad could give you either an X or Y chromosome. So nobody has 2 Y chromosomes. The chromosome is passed through by a sperm. So basically the sperm determines your gender. If you are a boy or man, the sperm from your dad had an Y chromosome, while if you are a girl or woman, the sperm had an X chromosome.

Marking a family in the genetical way sounds a bit complicated, since it can go on forever. Male people are marked by squares, while females are marked by circles. A couple is marked by the square on the left, the circle on the right. an unknown gender is marked as a diamond with a p in it. If adopted, the person adopted is marked as its gender inside a [ ], with a connected line to the person who adopted the other person.

We marked Harry Potters family in the genetical way. It was so fun. I had a great experience.

So as I have not done much of the project yet (for the final) I (more like we) have created a cardboard model using cardboard and a golf ball. I have a plan to create this on Imovie, though I am still a bit behind. Adding to the zip line, it can be used to push the truck other than the cylinder. I still have many choices to make. I was wondering if to use a TV box for the project, but my dad would not risk it because the project can damage it, and the box is relied on for exporting the TV. Without it, then we would have to buy another TV (possibly), which we do not want to happened. Otherwise, I look forward to the results of my project! 🙂

Expert Lecture Series#1

I am curious about this because this is the first time I am doing this. I am wondering who is the expert coming to our room. Our guest is here! It is Rania’s dad(Rania is in our rocketry group). Rania’s dad talked about money trade. I learned from this experience that people once used beads and salt for money. Soldiers used to be paid blocks of salt. Each country makes its own coins. Coins can be in various colors. Sugar was also used. People traded by many things back then. If there was a farmer and a hunter, the farmer would give the hunter some wheat, the hunter would give the farmer a deer skin. This way, everyone would have what they need. Money evolved when Chinese started to use paper as money. Eventually, it spread through Europe.

I had a good time for the first. It was interesting. 🙂

After Rania’s dad left, everyone started making something called “Boyer Bucks”. Every one started working like crazy. Me and Ronald worked on different things. Ronald made a  Boyer Buck and I made a sample coin(which can be used as a Boyer Coin). We wanted to 3D print it but we could not get in the website of Tinkercad. Before long, time was up. I had a great time.
