Haha! Stem class, it was a really tired and experience from stem class this round, I have learned about Newton laws Of Motion, and Newton laws of motion have three laws in there, the first Newton laws can also call as inertia and it is about Force and Motion. Newton’s first law of motion states that an object’s motion will not change unless an unbalanced force acts on the object. If the object is at rest, it will stay at rest. If the object is in motion, it will stay in motion. Inertia is the tendency of an object to resist a change in its motion. The inertia of an object depends on its mass. Objects with greater mass have greater inertia. To overcome inertia, an unbalanced force must be applied to an object. The second-newton laws of Motion are about Acceleration, Force, and Mass. Newton’s second law of motion states that the acceleration of an object equals the net force acting on the object divided by the object’s mass. Weight is a measure of the force of gravity pulling on an object of a given mass. It equals the mass of the object (in kilograms) times the acceleration due to gravity (9.8 m/s2). The third Newton laws of motion are about Action and Reaction. Newton’s third law of motion states that every action has an equal and opposite reaction. Momentum is a property of a moving object that makes it hard to stop. It equals the object’s mass times its velocity. When action and reaction occur, momentum may be transferred from one object to another, but their combined momentum remains the same. This is the law of conservation of momentum. Moreover, then Newton’s laws, we have learned about Fluid Forces and Work and Machines. Finally, we had an opportunity to do an experiment about Fluid Force with eggs and glass bottles here you can take a look!
Stem, stem is a class that we are studying about all earth nature things or how things were form, like a chair how did a chair form? So now we all have move on to studying about Carbon, Carbon is the one of the elements that can make or can form with a lot of things like chair table bad and other things else and the other important thing that Carbons can make Diamond, Diamond can form from only one element that was Carbon. We were also learning about Carbon cycle which it also related to Carbon also, The carbon cycle is the biogeochemical cycle which is carbon exchanged with biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is also the main composing of biological compounds as well.
My stem class, we were studying about the nature of the earth and everything ale but now we’re trying to study about element and when element makes or place how element form and or an element share the electron together. Also, we were trying to find out what is the thing that makes gold make silver or metal and other things. Element and from together such as we call it Alloy I hope you know that alloy is but I’m gonna explain what alloy is alloy is the mixture of metal and metal or nonmetal and metal but it can be nonmetal and nonmeat and as you know the alloy is the thing that use to make from metal and metal or nonmetal and metal so it’s nearly everything around us that is alloy and you can remember that alloy can be rusted if something that make from metal and it not rusted it must no alloy. So there more things that we have learned but this what I tell to know about and Thank You I Hope You Enjoy Reading.
In this term I was studying about the Physical Science . Physical science divided into 2 part one is Physical Property So what is Physical Property , Physical Property mean that the thing that we can touch , fell, color,texture and Physical science is when the glass break and it steal glass. Other one is Chemical Property , Chemical Property is the thing that we can not taught the thing that is born and when the physical property react and it will change it’s not gonna be the same Example: like the fire boun the wood so after it bourn it not wood any more soit is Chemical property. And we also study about Atom . Proton , Neutron, Nucleus and more . Space is what we also learn to and last but not less what is Science , Science is the study of the natural work that base on Logic and evidence.

And there is more thing that we have studies.
