Acids tasted sour, and bases felt slippery and can conterout acids. In nowadays, acids and bases are difined with hydrogen atom.     When we put acids and bases together, " neutralization" will appear.

 TED ED Video : Newton's Laws of Motion Have you been curious of motion? Even though you might not be a expert of physics, you must know the name of this great scientist,  Isaac Newton. Although you may think of some complex formulas when hearing Newton's Laws, in fact, we can use simple concepts and words to explain it, which is the most important fundation of science and technology.  🌐Experience of making video  　　 At first, we think the laws are difficult and not be able to understand with the knowledge we had learned. However, after we researched the information of it, we were aware of the principles of it, and we can use simple sentences to  analyze it easily.
