☆This is a delicious science convenience store☆
From elementary science curriculum linkage to recent environmental issues,
I'll tell you various science stories!

26 foods appear in "Buy Cookies and Get Science".
From sweets to bubble gum, cotton candy, cola, tang-hulu, sausages, tteokbokki, and hamburgers.
Each food item contains two scientific stories, so you can encounter a total of 52 scientific stories.

Let's take a look at the science behind the "Malgeumi Mineral Water" in the beverage corner. The first science question is, "How is mineral water made?"
We will learn how the drinking water we drink is made, and cover the elementary science curriculum, 'Changes in the State of Water'.
The second science is 'Why do microplastics come out of drinking water?'
We will explain what microplastics are, why they are created, and practical ways to eliminate them.
Because the issue of microplastics cannot be left out of recent environmental issues.
How about this? Isn't it surprising that a single food item contains elementary science curriculum-related information and current environmental issues?

Young readers can broaden their perspectives and deepen their thinking through the scientific stories hidden in convenience store food.
It's about asking scientific questions about everything in our daily lives, including food and objects, and finding answers to them, thereby learning about new aspects of science we didn't know before.

Why do cup ramen containers get narrower as they go down?
Does chewing gum relieve motion sickness? Why can't you stir canh khuur syrup?
Discover the science behind my favorite convenience store snacks!

It would be a mistake to think that we only cover science related to the curriculum.
Convenience store food becomes the speaker and tells science stories that children will enjoy.
Through topics such as "Will drinking water help when it's spicy?" for Bulgogi Bokkeum Myeon, "Why can't you stir the tanghulu syrup?" for Tanghulu, and "Will chewing gum relieve motion sickness?" for Bubble Gum, we provide useful tips to keep in mind in everyday life.
It also stimulates children's curiosity and arouses their interest through questions like, "What is the white powder on the surface of the chocolate?" in chocolate cookies, "How many corn silks are there in popcorn?" in popcorn, and "Would you rather have wheat or rice cakes?" in tteokbokki.

The fun of "Buy Cookies, Get Science" doesn't end there.
Each food item is marked with a percentage of scientific knowledge and life wisdom, so you can see how much of the curriculum content and everyday life tips each food item contains just by looking at the picture.
For fun, I also indicated the percentages of sweetness, crunchiness, savory, and sourness.
