Wonderful independent research

[For 2nd Graders] Make it with everyday materials! Irresistibly engaging ideas for independent research projects

10 years as a kindergarten teacher / elementary school teacher / junior and senior high school teacher / childminderkepiko
Graduated from Kunitachi College of Music, Faculty of Music (now: Department of Music Culture and Education, Early Childhood Music Education major). In elementary school, my homeroom teacher was Jun Kusaba, a game researcher. After graduating from university, I worked as a kindergarten teacher for 10 years and as an after-school childcare instructor for 7 years, then took a position as a music teacher at an international school in Singapore. In addition to music education, I engaged in activities that introduced Japanese culture, traditional games, and recreational activities, working with many children. Later, through freelance writing, planning, and editing at Shogakukan, I met many delightful adults and experienced the joy of communicating and sharing. Drawing on the perspective cultivated in the field of education and my experience as an editor, I provide practical information with an emphasis on both input and output, mainly in areas related to music and children. My hobbies include instruments, singing, handicrafts, toys, drawing, traditional games, the outdoors, and books. My special skill is spinning-top tricks.

During my student years at Kyoto College of Science and Technology, I studied a wide range of fields including sound, lighting, and video technology, building a foundation in comprehensive stage production and creative expression. After graduation, I joined a music production company, where I still work, consistently building experience in production and engaging in a variety of music-centered tasks. Currently, I mainly handle articles for children, drawing on what I’ve learned about parenting and what I feel and discover through daily interactions with my kids. I hope my work can be of help to you, even in a small way!

[For 2nd Graders] Make It with Everyday Materials! Irresistible Independent Research Ideas (21–30)

Torokira Keychain

Easy craft: glossy jelly keychains! Simple handmade project with 100-yen shop materials. Perfect for at-home time, summer vacation, and free craft or science projects. Great for beginners too. [100-yen DIY]

Torokira Keychain

Do you know those cute accessories with a little doll floating in a tiny plastic bag? You often see them as prizes at festival raffles, but actually, you can make them yourself.

You only need items mostly from a 100-yen shop—like a soft card holder, beads and glitter, liquid laundry starch, and masking tape—so it’s a budget-friendly craft project.

Add cutouts of your favorite character or idol to the decorations, and it instantly becomes merch for your fave! You’ll want to make them for everyone!

Transparent cute coaster

I tried making cute clear coasters! Perfect for a parent-child craft project over summer vacation, too!

Transparent cute coaster

Summer is supposed to be hot, but don’t you feel like the summers lately are getting hotter every year? When it’s hot, we crave cold drinks—so why not make coasters to brighten up your drink time and turn it into a summer science project? You’ll be using two-part resin and other chemicals, so be sure to have an adult or an older sibling help you when handling them.

Aside from working with the chemicals, it’s basically just decorating coasters, so even small children can join in! We’re looking forward to seeing your cool, refreshing coasters!

Fizzy Ramune Experiment

http://www.lemon8-app.com

Why not try making fizzy ramune tablets for your summer break science project and enjoy their colors and sounds when dropped into water? After thoroughly mixing ingredients like powdered sugar, cornstarch, and food-grade citric acid, add food coloring to make them visually fun.

Press the mixed dough with two spoons to shape it just right.

Let them dry for about half a day to finish the ramune.

When eaten, they fizz in your mouth, letting you experience the curious chemical reaction of carbonation.

It’s a safe project even for children, using the carbon dioxide produced by the reaction between lemon juice’s acid and baking soda.

You can boost originality by changing the colors and flavors.

It’s a great idea for learning chemistry with familiar materials.

Butter Even Elementary School Students Can Make

@nonno.chan
I recreated a summer vacation science project I made a long time ago: homemade butter!#Summer Vacation Independent Research #HandmadeButter Homework #tiktoksummerbreak #meiji Meiji Delicious Fresh Cream
♬ 3 minutes cooking style pop / cooking / sweets(957554) – ArcTracks

Here’s a summer vacation science project idea for making authentic butter at home using heavy cream, salt, and a plastic bottle.

Put heavy cream and a pinch of salt into a plastic bottle, close the cap tightly, and shake it vigorously.

After shaking for a while, the contents will separate into liquid and solids.

This is the sign that butter and buttermilk have separated.

Pour off the liquid, cut the bottle open with scissors, and take out the contents—the butter is ready.

Spread it on bread to enjoy a special flavor that really lets you feel you made it yourself.

Watching the cream change teaches about dairy processing and fat separation.

The hands-on, energetic shaking is fun and gives a sense of accomplishment, making this a great idea for elementary school students.

Milk Carton Rolling Tower

@silk_haru3mama
[Summer Vacation Craft/Independent Study] I made a rolling ball tower out of a milk carton 🌻#Summer Vacation Summer Vacation Independent Research Summer Vacation Craft translation #HandmadeToys work Independent Research Scrap Material Crafting Simple craft #AtHomePlay #craft
♬ Electro Swing Jazz – Retro, strange, mysterious(1137053) – Ponetto

Let’s reuse empty milk cartons to make a fun rolling tower where a ping-pong ball tumbles down! Cut the milk cartons and connect two of them to create a long cylindrical base.

Make holes and slits in paper plates, attach them in a stepped arrangement, and adjust the angles so the ball rolls smoothly through.

Add slits to the side of the cylinder so the ball won’t stop midway and will drop all the way to the bottom.

If you wrap the whole thing with a tube-shaped cover made from a clear file, the ball won’t fly out and it’s safer to play with.

A bonus is that kids can learn about gravity and incline through the speed of the rolling ball and the fun sounds it makes.

It’s an eco-friendly idea that uses recycled materials to create a moving, interactive project.

A piggy bank that helps you save while having fun

http://www.lemon8-app.com

Let’s use Daiso’s 3-tier drawer case to make a fun, game-like piggy bank over summer break.

First, flip the second and third drawers upside down and reassemble them so the flat sides face the front.

Next, cut corrugated plastic (plastic cardboard) into any shapes you like and attach it to the outside of the drawers to create a design that looks great.

Inside, apply double-sided tape so coins pause partway and drop slowly as they travel down.

With a piggy bank you made yourself, saving money becomes fun and easier to turn into a habit.

It’s a unique, practical idea that can change your everyday life through creativity and ingenuity.

Making Konpeito (traditional Japanese sugar candy)

http://www.lemon8-app.com

Let’s try making handmade konpeitō—colorful, cute sugar candies—for a summer vacation science project.

Boil sugar and water to make syrup, then gradually add small amounts of konpeitō cores; as you do, little spikes will slowly form on the surface.

By adding food coloring or flavorings during the process, you can customize the taste and color to your liking.

Even without special equipment, you can keep stirring and improvising with a frying pan or a bowl; it takes time, but the candies will gradually take on the characteristic konpeitō shape.

Because the results change depending on the temperature and timing of sugar crystallization and how you stir, it’s also enjoyable as a science experiment.

It’s a rewarding idea that nurtures both confectionery skills and observation.
