In the Liger Leadership Academy, there is an essential that focus on Science, Technology, Engineering, and Math(STEM). In this round, Junior students have been working on the periodic table in STEM class and I am so excited to learn with those interesting lesson and understanding how elements work scientifically.
Periodic table
Periodic table was a really interesting topic for me to learn and I feel really passionate about this lesson as my facilitator have explain and did some experiments during this class. For this topic, I can also catch up the lesson quickly because all of the content are so excited for me. In the periodic table we have been learning about its group and period and the history of the periodic table including the purpose of making the periodic table. Periodic table are so hard to organize, but when we know how it work it will be really easy for us to understand the periodic table. Dmitri Mendeleev was a teacher Russian as well as a chemist and Mendeleev has been creating a chemistry textbook and he was having a problems with organizing elements and he needed a way to organized the elements to make the students easier to learn about chemistry. By 1860s, Mendeleev has made a set of card that have the name of the elements, atomic mass and known properties. He arranged and arranged the card in many different ways and finally he found it when he placed the elements in order by atomic mass. Elements in the periodic table are organized by its atomic number now, because during the 1860s, scientist cannot recognize the atomic number of elements, but they can recognize the atomic mass of an element.
