Science is taught in a fun way that children can understand. The little question mark means that the little girl about 8 years old likes to ask questions, and the exclamation mark means the little boy about 9 years old likes to be surprised. Start with scientific issues in nature to discover and understand the truth behind things, improve children's scientific and cultural knowledge, and achieve the goal of loving science since childhood and taking pleasure in researching and exploring science. Little Question Mark's parents, grandparents, and grandparents are all Little Question Mark and Exclamation Mark's teachers. They teach Question Mark and Exclamation Mark all kinds of scientific knowledge, focusing on novelty, strangeness, and weirdness. They ask questions because they are strange, and they sigh because they understand scientific principles.
