The Cepheid Science Series—Infinite Imagination—is Korea's first science textbook to cover all of middle and high school science and creativity topics, organized into five stages: Middle School Basics (1F), Middle School Completion (2F), High School Completion 1 (3F), High School Completion 2 (4F), and Practical Problem Solving (5F). Now you can enjoy studying science with ease.

The contents of one unit were divided into four pages and organized.
Concept Confirmation, Confirmation+, Concept Reinforcement: This is a problem-based approach that allows you to easily solve and organize the content using the lecture content.
The content of the relevant sub-units is divided into types, and representative problems and practice problems are presented for each type so that students can discuss and solve the problems.
By presenting a wealth of creative problems related to the content of the relevant sub-units, we aim to enhance creativity while also naturally eliciting questions and facilitating discussions on related topics.

A sufficient number of review problems and assignments for each level of learning were provided.
ABC-Advanced level allows you to improve your skills step by step by increasing the difficulty level.
At the end of each unit, reading material on the topic was provided to answer descriptive/argumentative questions, and the main experiments of the unit were presented so that students could conduct them individually.
STEAM activities will be possible because convergent problems are presented together.
