In STEM I’ve learned a lot of thing such as chemistry, energy, weather, matter, astronomy and etc…. For this few we mainly focus on matter and also we dig a little into chemistry. The website that our facilitator use to teach and read is called CK12. This website is really helpful to me because it explains in very detail and it uses a lot of examples to explain to us. I can learn it and understand more about it by myself without facilitator just to read. I’ve learned many things from and matter. Matter defined anything that has mass and volume. There are two properties in the matter which are physical properties and chemical properties. Chemical properties are the properties of matter that can be measured or observe only when changes form and become something else. Physical properties are the properties that can be measured and observed without matter changing to different substances. One interesting thing about mass and weight that most people make their mistake of saying those word. So mass is the amount of matter in substance or object and its unit called Kilogram but the weight is a measure of the force of gravity pulling on an object and its unit known as Newton. So you should say your mass is 62 kg not your weight is 62 kg. Don’t be confused!!!.
One more thing that I’ve to learn about atoms which are related to the STEM. Atom is the smallest particle of an element that still has an element of the property.
So in the matter, there is the element, the element there are atoms, an atom, there are nucleus and electron and in the nucleus, there are proton and neutron. You might wonder what proton and neutron made from. Well, proton and neutron made quark and electron made from leptin. That’s is most of the thing that I’ve learned so far in STEM class. Hope you enjoy!!
