An Intelligent Schoolbag
Nowadays, the traditional schoolbag is very heavy and it is tiring for students to carry it for a long time. So I decided to do something to help. I spent some time studying and inventing a new type of schoolbag — an intelligent schoolbag.
My intelligent schoolbag is different from the common one. It weighs only about 500 g. It is much lighter than the common one. Besides, it can change its size, so it can meet different needs of students. With a GPS system, parents are able to find the schoolbag through a mobile phone. What’s more, students have to use their fingerprints to open the schoolbag. It is much safer for students. What a helping schoolbag!
Inventions show people’s creativity. They help to solve problems and meet needs in people’s daily life. In my opinion, with a strong sense of curiosity and the courage to try, common people may create useful inventions.
