The word “basic” is an adjective that is forming an essential foundation or starting point or fundamental. This subject is one important part of our daily lives. For everything there is chemistry, not just in school, but everywhere. This is the stepping stone of the scientists of the next generation for they will have the power to innovate lives for the better. 

            From learning the uses and care for different laboratory apparatuses, gives the learner knowledge and carefulness of movement inside the workplace. To understanding atoms and elements, for these may seem to be complicated for some, but essential lessons to comprehend. I can say that chemistry is fascinating just from the Periodic Table itself, because it is well-studied, well-measured, and well-constructed. There is nothing for me to worry about as I continue learning chemistry but I just hope that the teacher-student interaction will be an effective way of learning.

Chemistry has been a necessity to our daily life like how important it is in school. Last week, we learned about the classifications of matter and how to use periodic table.

Matter has two main classifications: pure substance and mixture. Pure substance is a matter that has a definite and constant composition. A pure substance can either be an element, compose of a single atom, or a compound that is composed of two or more elements. An example of pure substance is gold while an example of a compound is water. Another classification of matter is mixture. It is a matter consists of two or more substances that are physically mixed but not chemically combined. A mixture can either be a homogenous or heterogeneous. Homogeneous mixture, or often called solution, has the same uniform appearance and composition while heterogeneous mixture are consist of visibly different substance or phase.

Periodic table is an arrangement of chemical elements by their atomic number. Each element ca n be classified by groups (vertical) or periods (horizontal), or as metal, nonmetal and metalloids. Each element has its number of neutrons, protons and electrons. These are used to determine its mass number and atomic number.
After each lesson, we take an activity to test if we really understand it. At the end, we learned how to determine if a matter is a pure substance or a mixture, and how to get the mass number and the atomic number of a element by using the periodic table.
