In tech, I finished my pendant. I left off saying I was putting it together, right? Anyway, after I put my pieces together, I soldered. I was kind of scared, because The soldering iron gets up to 842˚ F, and I didn’t want to burn myself. It was really cool! There was liquid metal oozing out of the iron, but almost as soon as it hit air, it dried, and was not hot anymore!! Overall, I really liked doing this, and am proud of what I made.
In technology, we have been working on wire pendants. This basically means that we are making jewelry out of wires. This is our first real project! The first thing we did was brainstorm designs. Our designs had to have only 5 wires, because we are just beginning. We made 15 designs, all of them were different. Then we picked the one we wanted to make. I chose a simple sunset design. The second thing we did was we made our circles that we were going to put our design in. We did this by using a cylinder made out wood, to wrap them wire around and create a perfect circle. Then, we very tightly wrapped the remaining wire around the wire we didn’t touch before. Overall, I am super excited to continue working on this project!
In technology yesterday, we did an experiment about how effluvia (static electricity) moves a piece of tinfoil inside a jar. In the experiment, we rubbed a plastic stick on wool. This transferred the electrons from the wool to the plastic. Then you take the stick, and put it close to the rod attached to the tinfoil. Since the rod was also filled with electrons, the electrons in rod went to the tinfoil, since electrons don’t like each other. Then the tinfoil moved because the electrons were trying to get away from each other. Overall, I really liked this experiment!
In tech we played breakout. The object of the game was to unlock the box with the safety glasses in it. We had work as a team to find clues, and then decipher the clues to find out the code for the locks. Our group was at first mystified by the clues, but then, after a hint from Mr. Calvert, we understood the clues and began to read between the lines. When we finally got it open, we got started on the mystery box. And we got that open too! Overall, this was a really fun day in tech!
Our first day in tech, we learned about safety and what we are going to do in tech. We learned about the rules, safety precautions, and the different tools that we need to be careful around. We also learned about some cool units we are going to do. For example, circuits. We will do a whole unit abut circuits. Overall, I’m really excited to continue tech!
We have now presented our capstones to some of the kindergarten and second grade classes. We also presented on camera. It was very nerve racking and kind of scary too. I performed fairly well, and messed up only a few times. It was also an exciting experience, as we had finally finished capstone! I felt relieved when i finished because all of the tension had been building up inside me. When I was actually presenting, I was thinking very carefully about what I had to say, especially the parts where I usually have trouble. I tried to be relaxed, but it was extremely hard. I was a little more relaxed at the live performance. Overall I really enjoyed capstone, and learned so much from it. It was such a fun project!
I have finally completed my research and answered my main inquiry question (see Capstone 1 and 2). I have learned so much. For instance, I never knew the process to FDA approve a drug. I definitely didn’t know how complex that process is. I also learned a lot about the cons of vaccines. I knew the pros, but not so much the cons. I also learned a lot about the laws surrounding vaccines and how mis-information affects parents decisions about whether or not to vaccinate their child. Overall, I learned so much! I am so excited to take the next step forward and put together my presentation.
Today in class, we did a series of experiments. We tested how colored sugar reacted to oil, water, and white vinegar. The liquids were the solvent and the sugar was the solute. First, we had to make the colored sugar by mixing sugar and pink food coloring.
Then, we tested the sugar with the oil. Our hypothesis was: If we mix 1 tsb of sugar with oil, then the sugar will gradually dissolve and color the oil. Our hypothesis was denied. We noticed that there were tiny particles floating and there is a thin layer of pink at the top. We also noted that the sugar was NOT coloring the oil and that most of the sugar was at the bottom.
Next, we tested the water and sugar. Our hypothesis was: If we mix 1 tsb of sugar with water, then the sugar will dissolve and color the water. Our hypothesis was confirmed. The sugar DID color the water and dissolved rapidly. It took a little bit of time, but by the time we came back from lunch, (1hr), it was all dissolved.
Finally, we tested the sugar with white vinegar. Our hypothesis was: If we mix 1 tsb of sugar with vinegar, then the sugar will color the vinegar and partially dissolve. Our hypothesis was confirmed. The sugar did color the vinegar and dissolved rapidly, although not all the way.
Overall, I learned so much from these experiments and had so much fun getting messy!
Capstone is still going well. I have done my interview (see Capstone #3). Next, I am going on my site visit. For my site visit, I am going the American Museum of Natural History’s exhibit Inside You. At first I wanted to go to a specialized exhibit on vaccines, but my mom and I couldn’t find any that were still open (or that weren’t in California!) So, we went with this instead. I think we are going to go on Saturday, June 1st. I can’t wait!
My site visit went really well! What happened was I went into the exhibit. There were a lot of people there, as it is open to everyone. I was amazed by the different diagrams and pictures. Even though I have been there before, when I was looking at the exhibit through fresh eyes, I was surprised at how much information there actually was. My mom took picture of the diagrams for me to review later. It was really fun!
I learned so much from this! Instead of learning about vaccine, I learned about the immune system and about microbes and that helped me understand the science behind vaccines better. It was really cool to look at this exhibit with fresh eyes and to learn so much from it!
