STEM

STEM or stands for Science Technology Engineering and Mathematics is one of the most important subjects in school. STEM is really important for everyone because everything surrounded us is related to STEM. We learn with our facilitator Da. He is also a Cambodian like us, too.

I really enjoy learning with him because he gave us to do a lot of fun activities and we can learn a lot from those of the activities. One of the thing that I learn in this round is about the atom. He divided us into the different team and he gave us different responsibility and gave us to do research different thing that related to atom. I got to learn a lot more about quark from this project. First I thought that atom is the smallest elements in the whole universe, but actually, quark is even smaller than an atom. As you know that there are three more things in an atom which are electrons that have a negative charge (-), Protons that have a positive 

Different type of team of quark and how much it charge

charge (+) and Neutrons that have zero charges (0) and quark actually made up neutrons and proton. There are six different type of quarks they are up, down, strange, charm, bottom, and top quark. Six of those quarks also divided into two different teams and each them charges a different amount. In a proton, there are two up quark and one down quark and in neutron, there are two down quarks and one up quark. That the basic of quark and I hope you learn something from reading this.
