Chapter 176 Popeye of the Learning World
Yuan Bao beamed with pride, his face radiating unconcealed smugness. He grinned at his mother and said, "Hehehe! Mom, don't worry, just wait and see! What I gave my older brother is a 'miracle drug' that will completely unlock the wisdom in his head!"
Upon hearing this, Yuan Ma raised an eyebrow slightly, her face full of suspicion, wondering what this little girl was up to now.
However, she still went along with Yuan Bao's words and replied gently, "Okay, okay! I'm just waiting to see the miraculous effects of your 'miracle medicine'."
You two siblings have grown up and become more sensible, which has indeed saved your dad and me a lot of worry.
As long as you are safe and happy, we parents are content and happier than anything else.
Bao Guo was beaming with excitement, his eyes sparkling. He slapped his thigh and exclaimed, "Yes, yes, it's done! I just 'ate' this spinach that boosts my motivation to study, and now I feel like I'm transforming into Popeye of the learning world, full of energy. I need to take advantage of this momentum and get right to doing practice problems!"
The words were still echoing in the living room when he had already disappeared into his room like a gust of wind.
Seeing this, Aunt Yuan's smile deepened, her eyes filled with satisfaction. She gently shook her head, and the corners of her mouth unconsciously turned up.
Seeing this, Yuan Bao said cheerfully, "Mom, I'm going back to my room to study too!" With that, he turned around and walked briskly into his room.
From behind came Aunt Yuan's voice: "Okay, okay! Go on, go on!"
After entering the space, I sat down at the desk, my gaze falling on the bookshelf. I thought to myself that I had already completed my self-study of high school physics, and it was time to start a new journey.
After a moment's thought, she reached for her chemistry textbook and decided to start with the basic chapters.
Yuan Bao knew the importance of building a knowledge framework. She first carefully read through the textbook's table of contents and then, in her notebook, outlined the general structure of chemical knowledge according to the chapter order.
From the classification of substances and the periodic table to the principles of chemical reactions, each section is clearly labeled.
Next, she skillfully used mind maps to deepen her understanding of each chapter.
For example, when studying the chapter on "redox reactions", she used "redox reactions" as the core theme and expanded it into branches from aspects such as concepts, characteristics, essence, and the differentiation of related concepts. Each branch also recorded key knowledge points and typical examples in detail.
Under the "Characteristics" branch, she wrote "Changes in the oxidation states of elements" and marked examples of changes in the oxidation states of iron and copper in the reaction of iron with copper sulfate.
When memorizing chemical equations, Yuan Bao uses the method of experimental association.
When learning about the reaction of sodium with water, she closed her eyes and vividly simulated the experimental scene in her mind: the sodium block was put into the water, floated on the surface of the water instantly, reacted violently, swam around, made a "hissing" sound, and produced gas.
Through this kind of association, she not only easily memorized chemical equations, but also gained a deeper understanding of reaction phenomena and the properties of substances.
When encountering abstract concepts that are difficult to understand, such as "chemical bonds," Yuan Bao would use the resources available in the space to watch relevant animated demonstration videos, which would intuitively show the interactions between atoms in the microscopic world.
At the same time, she would also search for relevant academic articles online to broaden her knowledge and deepen her understanding of the concepts.
During the learning process, Yuan Bao also conducts regular self-assessments.
After completing each chapter, she would select relevant practice questions from the supplementary materials to practice. After finishing, she would carefully check her answers, analyze the reasons for her mistakes, and compile the easily confused knowledge points into a mistake notebook, noting the reasons for the mistakes and the correct problem-solving approaches.
And so, the room fell silent, with only the rustling of pages turning and the scratching of pens on paper. Yuan Bao was completely absorbed, plunging headlong into the wondrous ocean of chemistry, and had entered a state of selfless study.
At this moment, the advantages of the space became apparent again. When Yuan Bao got excited, he could be in front of the experimental table in the blink of an eye without any complicated preparations, and could start conducting experiments at any time. Where else can you find such an advantage?
Yuan Bao had previously watched many time-travel dramas, and she was particularly impressed by the plot in which the protagonist made a fortune in ancient times using crude salt purification technology.
At that moment, a surge of eagerness welled up inside her, and she thought, "Are the methods in the drama really that magical? I want to verify them myself." So she rubbed her hands together, ready to show off her skills.
Yuan Baoxian took out a suitable amount of coarse salt from his spatial storage. The coarse salt particles were of different sizes, dark in color, and mixed with some mud and other impurities.
She picked up a clean glass beaker, slowly poured coarse salt into it, and then used a graduated cylinder to measure a certain amount of distilled water, which she slowly poured down the side of the beaker.
Then, she picked up a glass rod and began stirring at a constant speed.
As the glass rod rotates, water churns in the beaker, and coarse salt particles gradually disperse and dissolve in the water.
While stirring, Yuan Bao carefully observed the process. She noticed that some of the larger particles dissolved more slowly, so she increased the stirring intensity slightly to ensure that every grain of coarse salt could fully contact the water.
Once the coarse salt had completely dissolved and the solution became turbid, Yuan Bao knew that filtration was the next step.
She took out filter paper from the experimental tools, carefully folded the filter paper twice to form a small fan shape with four layers, and then put it into the funnel. She moistened the filter paper with a small amount of distilled water, making the filter paper stick tightly to the inner wall of the funnel without leaving any gaps.
She placed the funnel on the iron stand, with a clean beaker underneath, ready to collect the filtrate.
Yuan Bao held a glass rod and gently placed one end against the three layers of filter paper. Then he slowly tilted the beaker containing coarse salt water, allowing the turbid liquid to flow slowly down the glass rod.
Under the filtration effect of the filter paper, insoluble impurities are intercepted on the filter paper, while clear liquid drips into the beaker below, and the originally turbid solution gradually becomes clear and transparent.
After completing the filtration, Yuan Bao looked at the clear filtrate with anticipation in his heart.
She poured the filtrate into an evaporating dish, placed the dish on an asbestos mesh on an iron stand, and lit an alcohol lamp to begin heating.
The flame licked the bottom of the evaporating dish, and the water in the filtrate began to evaporate gradually.
Yuan Bao held a glass rod and stirred the liquid continuously in the evaporating dish to prevent it from overheating and splashing.
As the water content decreases, the solution becomes increasingly viscous, and white crystals gradually precipitate out.
When a large amount of solid appeared in the evaporating dish, Yuan Bao turned off the alcohol lamp and continued heating using the residual heat to completely evaporate the remaining moisture.
Ultimately, the evaporating dish was left with fine, white salt, a stark contrast to the original coarse salt.
Looking at his work, Yuan Bao smiled with satisfaction and couldn't help but marvel, "It turns out that purifying crude salt can really change the quality of salt so much. The plots in those time-travel dramas actually have a scientific basis."
