Dictionary of Scientific Terms

A science brain roadmap starting in elementary school!
Learning the Basics of Science with Pictures: Elementary Science Encyclopedia

Children who are good at science have a different ability to understand the world.
Awaken your child's scientific brain with the Elementary Science Encyclopedia!

1. Vivid pictures and photos
Visible scientific phenomena are depicted in real photographs, and invisible principles are depicted in easy-to-understand drawings.
Even children who find science difficult can approach it in a friendly way.

2. Build a foundation by learning all four scientific fields equally
Core contents of elementary and middle school science textbooks
It is organized into four areas: earth science, physics, chemistry, and life science.
Build a solid foundation in elementary school and you'll be able to easily master science in middle school!
It's a solid science encyclopedia that you can refer to for a long time.

3. Satisfying children's curiosity
“Why does the sun set early in winter?”, “What happens to balloons that fly into the sky?”
Answer questions your child has always wondered about using scientific principles.
It's a science story written in an easy-to-understand way for children.

4. A perfect ending with a 'quiz' and 'terminology summary'
There is a quiz to check what you have read.
There is a glossary organized in alphabetical order, so you can easily look it up like a dictionary.
Make the knowledge of the science encyclopedia your own with post-reading activities.
