Flagpole, crane, gravity light, elevator, etc.
Through inventions that give us a glimpse of ingenious ideas,
The principle of pulleys, gravity, the law of the lever, etc.
Discover scientific theories from textbooks in an easy and fun way!

In Volume 44 of “Tomorrow’s Inventors,” the “Pulley Invention Controversy” section, scientific theories are naturally introduced through inventions such as flagpoles, cranes, gravity lights, and elevators, and various inventions related to pulleys and their operating principles are learned.

In addition, we have organized the core principles in the textbook that students must know, such as levers and inclined planes in the '3rd grade, 1st semester - Force and Our Life' unit of the science textbook, and renewable energy in the '5th grade, 2nd semester - Resources and Energy' unit, in an organized manner to increase the learning effect.
It is packed with interesting comics and useful information.
In 'Explore at Home,' you'll build a flagpole using pulleys and string and learn about fixed pulleys.
In 'Inventions that Changed the World,' we look at the crane, and in 'Inventions in Everyday Life,' we look at various inventions that use levers, such as scissors, tweezers, and chopsticks.
In 'Invention Diary', we look at the process of coming up with invention ideas related to gravity by learning about the Goldberg apparatus and other things.
In 'Invention Report in Comics', we will create a simple gravity lamp, one of the appropriate technologies.
'Key Notes' is organized so that you can understand pulley-related information at a glance, including fixed pulleys, movable pulleys, and compound pulleys.
