STEM is a study about so many things that are around us. The definition is, the study of all the environment that are around us by using logical and experiment or observations. We have learned about types of matter and its changes throughout the reaction. I really like this lesson than the next one because I really understand them well without any wonders. The examples are also easy to find and the types are simple and fast to identify. The quick tip that we need to understand is, the two types are opposite of each other, so if you remember one of them, you could remember all of them for sure. The last lesson is about element. We have research about the element names and basically what does it form. However, we only choose a few of them to research and those are the things that are in the Atom groups. Science is very fun!!
