Today Jackie Bastardi from Curious on Hudson came in and told us about being a mechanical engineer. She said engineering is a lot of fun. There are lots of  projects you can do. Once, there was a 3D designing competition, and the winner gets their model design 3D printed. She also told us a lot about stories of her career. The “Gallopin’ Gertie” was also mentioned throughout the talk. It was about a bridge that collapsed because of the winds. In the end, we all made kazoos. It had popsicle sticks, straws, and paper. The paper vibrates to make the sound. I had a fun experience.

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.
