Wonderful independent research

Recommended for elementary school students! Science fair topics & craft ideas

Speaking of summer vacation, choosing a topic for the independent research project can often be tough.

Science experiments and crafts are both fun! If your child is good at crafts, we recommend crafts because they can enjoy the process as they go.

When they get absorbed in it, they might even finish in just a few days.

Here, we’ll introduce a variety of ideas for independent research and crafts! If you’re struggling to pick a theme, please use these as a reference.

To create fun summer memories, make a one-of-a-kind project of your own!

For upper grades (231–240)

A capsule toy machine made from a candy box

Let’s make a capsule toy machine that makes use of candy boxes as packaging! The cool thing about this machine is that you can change what comes out depending on whether you turn the dial to the right or to the left.

Press in the bottom part of the box so it forms a slope.

If you use an empty cylindrical candy container for the turning dial, you’ll have an adorable candy-themed capsule machine! Of course, you can fill it with the candies that came in the box, and you could even put in one different candy or a special “winner” prize inside!

beetle (specifically, a rhinoceros beetle)

[At-home time] I made a rhinoceros beetle and a stag beetle using a glue gun from the 100-yen shop!!
beetle (specifically, a rhinoceros beetle)

Let’s try making beetles and stag beetles—the classic insects of summer—using a hot glue gun.

If you use the finished pieces as decorations, they’ll really emphasize a summery atmosphere.

Create each part on a sheet of parchment (baking) paper, and then glue the parts together at the end to complete the model.

Giving each piece a good rounded shape is an important point for achieving a three-dimensional look when it’s finished.

You can aim for a realistic appearance, or play with colors and shapes to create your own original creatures—it could be a lot of fun.

camp

Cooking a meal in the mountains, listening to your favorite music, and gazing at the stars.

Is it really okay for an event to be this wonderful? Yes—it’s camping.

Cooking together as a family and living in a space different from the everyday will surely feel fresh, and you’ll probably have conversations you don’t usually get to have.

Let’s all think about what kinds of dishes we can make without using electricity or gas!

cardboard picture frame

[Cardboard Art / DIY] A Picture-Frame-Style Frame Made from Cardboard
cardboard picture frame

Let’s try making a lovely frame to display photos, certificates, and commemorative items from marathons or volunteer activities—using cardboard.

Imagine a square frame measuring 30 cm on each side.

First, secure the space to hold the photo or certificate, then create beautiful embellishments around it.

Ideas are endless: a whirlwind-style frame with circular motifs, a mosaic look combining triangles and quadrilaterals, or a design like torn-paper art using colorful pieces of cardboard.

It’s also worth noting that simply combining gold and silver paint can make cardboard look metallic.

Show off your sense of style to the fullest!

Tapioca drink with tape

[DIY] Make Viral Nano Tape Bubbles: How to Make a Tapioca Boba Tea Squishy — Making a Tapioca Drink Milk Carton Squishy with Tape
Tapioca drink with tape

Why not try making a boba drink using clear gel tape, a craft item that’s been very popular lately? It’s a perfect DIY idea for girls who love stylish projects.

Its charm lies in how realistic it looks, with a finish that resembles food samples.

The method is simple: use liquid laundry starch (or glue) and borax to make a milk tea–colored slime, create a milk-carton-shaped container with gel tape, and add black deodorizing beads to mimic tapioca pearls and square acrylic pieces to mimic ice, then combine everything with the milk tea slime.

It’s a fun craft with a satisfyingly tactile feel that you’ll want to touch forever.

Newton’s cradle

[Science Experiment] Perfect for Independent Research! A Newton’s Cradle You Can Make Using Only 100-Yen Shop Items [Budget-Friendly Craft]
Newton's cradle

Have you ever heard of Newton’s cradle? It’s a device where about five small steel balls are suspended on strings in a row.

When you lift and release one ball at the end, only the ball on the opposite end is knocked outward.

This is related to the conservation of momentum and the conservation of mechanical energy.

Let’s write a report summarizing the results of changing conditions—for example, what happens if you lift and release two balls instead of one, or what happens if you change the size of the balls.

Another nice point is that after the experiments, the Newton’s cradle you made can be displayed as interior decor.

Plastic Bottle Cap Calendar

Easy! DIY Blackboard Calendar Made with Bottle Caps! [CAINZ DIY STYLE]
Plastic Bottle Cap Calendar

In the old days, when the year-end approached, we used to receive calendars from the local shopping street and neighborhood stores, and our house would overflow with more calendars than we needed.

Now it’s an era where we buy calendars to suit our purposes.

For a summer project, you can make a perpetual calendar using plastic bottle caps—depending on your ideas, it could turn out to be a wonderful calendar.

The materials are a corkboard, pushpins, and plastic bottle caps.

The basic setup is to fix the days of the week—Sun, Mon, Tue, and so on—on the corkboard, and then line up bottle caps labeled with the dates.

Think of hooking them onto large-headed pushpins.

You’re free to decorate the bottle caps with beads or even make them light up with miniature bulbs—the ideas are limitless.

Take the whole summer to create a lovely calendar!
