What is a top student, that is, a student who is good at learning and has a high score in each subject. Here, Xiao Song wants to emphasize one word, "every door". However, in the primary school curriculum, there is a subject that is encountered in every exam, but parents are easy to ignore a "non-major subject" - that is, "science".

Therefore, especially in the sixth grade, it is imperative to work hard to learn the subject of "science". Why? First of all, "science" is different from "non-verbal", it does not have many test points and it is not easy not to lose points.

Students who usually work hard and hard will get a full score in the final exam.

In view of this, Mr. Xiao Song has made a comprehensive and systematic combing and summary of all the unit knowledge points of the second volume of science (JK version) in the sixth grade. It can be said that the content of the exam is basically included, so you must keep these in mind! At the end of the article, there will also be an issue of the latest "Six Science Final Test Papers", and students can test them on their own against these unit test points.

In fact, science in primary school is to pave the way for several compulsory courses (such as biology, physics, chemistry, etc.) after the primary school promotion, and the subject of science can also exercise their own thinking and creative ability when cultivating children's interest in nature and science, which is really beneficial to children's future learning and physical and mental growth!
