In Quarter one we directed our focus towards chemistry. At the beginning of this section I already knew that all the things on earth and in the universe is made of matter. Everything that you own your phone, laptop and your body is made of matter, but one thing is didn't know is that matter is made of atoms and atoms are made of protons, neutrons and electrons. Atom are the smallest particle of a chemical element that can exist. atoms are made of three things protons, neutrons and electrons. Protons which have a positive charge and neutrons which have no charge make up the nucleus which in turn has a positive charge because of the protons. Meanwhile outside the nucleus the electrons containing a negative charge are circulating the nucleus. That the breakdown of matter and the atoms that make the universe.
On the way I also discover the periodic table which I didn't know existed till now. And the periodic table arranges the chemical elements in order of atomic number. I also didn't know about chemical changes and physical changes which occur everyday around us. Like a common example f chemical change is oxidation or rusting which almost every one ha seen. Oxidation is a chemical change because it is irreversible and cant be used again. Also it changes the appearance and texture of the object. In school we did and observation in groups of two finding the different chemical and physical changes that occur around our school. Below is the link to our presentation.
During quarter one we also researched about how the universe was created but this research is not complete yet we still have to find out how the sun came to be and the earth ans the stars and more. During the course of this quarter ii have learned a lot in Mrs Ahmed's class which has given me a different perceptive of the world. I hope to learn even more as the year goes by.
