★ Author Iwamama is a former high school chemistry teacher and mother of one. Since June 2022, she has shared home experiment content on Instagram, with over 130,000 followers as of 2025. She has published 2 experiment books and developed and sells the “Ouchi Experiment BOX” kit.
★ The series uses photo picture books to show “before” and “after” experiment comparisons, so children understand at a glance and want to turn the page themselves.
★ Aligned with elementary science curriculum and usable as a classroom introduction. What happens when you blow on a candle flame? What happens when you bring a stone, bead, paper clip, or bill close to a magnet? What happens when you put a plastic ball and a clay ball into water?
★ Almost all experiment tools can be found at 100-yen shops. No special equipment is needed—parents and children can do the experiments together. The end of the book includes commentary for teachers, helping extend the experiments into further learning, and it is also great as a holiday free-research inspiration!
★ The book uses the “What happens next?” question to drive children to first ask “Why?” and “I want to know,” then verify by doing, and finally think about “Why”—this is what matters most in science education.

Series includes 3 books:
“What Happens Next? The Secret of Magnets”
“What Happens Next? The Secret of Air”
“What Happens Next? The Secret of Weight”

"What Happens Next?" Series Book 2! A photo picture book of experiments that "happily supports elementary science learning." It can be used as an introduction to Grade 3 "The Work of Wind and Rubber Forces" and Grade 4 "Properties of Air and Water."

Science units are said to be a source of difficulty; spiral learning begins in Grade 3 and becomes more complex each year. This book uses "What happens next?" as its entry point, making the experiment process clear at a glance and stimulating children's curiosity.

【Key Points】
● Spark interest at the start of class! — A sailboat toy on water, a warm drink, a marble... What happens when you blow on them? The "What happens next?" that grabs children's hearts.
● Almost all tools available at 100-yen shops! — "I want to try!" "Let's use it for a free research project!" Because materials are easy to get and can be made by hand, children can try it themselves!
● Stimulates curiosity and connects to the next interest! — Surprising experiment results using cup noodle containers and large pinwheel rings make children ask "Why?" and "I want to know!"

The end of the book includes commentary for teachers and other "adults," helping with the next step in learning.
