Elementary School Students: Simple One-Day Science Project and Craft Ideas
For elementary school summer break projects and crafts, we recommend starting with something your child is already interested in.
When it’s something they like, they can enjoy working on it.
Here, we introduce simple ideas for elementary school students! These are experiments and crafts you can do in a single day.
The materials are things you already have at home or can get quickly, so even if you’re short on time, no worries.
Perfect for those who are “stuck on a theme” or “looking for an easy and fun project”! Find your favorite and give it a try.

Paper chromatography
Chromatography refers to a method for separating mixtures, and paper chromatography is a type of chromatography that uses water and filter paper.
Although chromatography might sound like a formal chemistry experiment, it’s actually easy to try as a hands-on science project.
One simple activity is to use paper chromatography to separate the inks of water-based pens.
Water-based pen ink is made by mixing various colors; for example, when you separate green ink, you can see that it’s composed of multiple colors.
The method is simple: color a coffee filter with a water-based pen, then dip it in water and leave it.
The ink will separate as if it’s bleeding, revealing which colors were mixed.
Try separating and observing different colors, or investigate whether the mixture of colors differs between brands even for the same ink color.
Botanical candle
Let’s add a creative twist to candles and make cute botanical candles.
The process is simple: pour melted wax into a candle mold and let it set.
A key feature is the double structure: a central core where the flame burns, and an outer layer sprinkled with dried flowers.
This design ensures safety by preventing the flame from catching the outer decorations.
It’s also important to place the dried flowers with small gaps so the wax can flow and solidify properly—keep balance in mind as you work.
Express your originality through your choice of dried flowers and other decorations.

Magic hand
A magic hand is a device where you use a mechanism to move a hand motif that’s larger than a real hand.
The unique mechanism gives it a slightly awkward motion, which is fun to watch on its own.
To make one, cut construction paper into the shape of a hand, leave openings at the finger joints and apply double-sided tape, then create the “bones” with short pieces of straw.
After that, thread string through the straws and you’re done—when you pull the strings, the fingers curl at the joints.
To make it easy to tell which string controls which finger, it’s recommended to use different-colored straws and match the color at the end of each string to the straw it runs through.
Making a Metal Slime
Many elementary school students love the Dragon Quest series, which is hugely popular in video and smartphone games.
We also recommend making the series’ popular monster, the Metal Slime, as a craft project.
In this craft, you’ll use a metal called gallium, which melts at low temperatures.
By the way, gallium can make other metals brittle, so be careful not to spill it.
Melon cream soda
Melon cream soda is also appealing for its vibrant appearance—the green color topped with ice gives a refreshing feel, doesn’t it? This is about trying to recreate that beautiful, summery look of melon soda.
The steps are simple: put jelly clay into a plastic cup, insert a straw, and place a scoop of white clay “ice cream” on top.
Combine elements like jewel stones and glitter to make the most of the light and finish it with a sparkling look.
The closer it looks to the real thing, the more you might feel disappointed when you remember you can’t actually drink it.
Color the shapes created by a single-stroke drawing
Let’s try a “one-line drawing” that can produce artwork like an artistic painting.
Draw a border with a marker slightly inside the edges of your drawing paper.
From the top of the border to the bottom, draw continuous lines in a single stroke.
As you add more lines, they will intersect and create several shapes.
Color those shapes with colored pencils in any colors you like.
Even with the same colored pencil, varying the pressure will create light and dark tones, making it more artistic.
You might end up with a picture like Picasso’s—give it a try!
Cook home-style dishes from countries around the world
How about a tasty independent research project? In this project, you’ll explore home-cooked dishes from countries around the world.
Of course you’ll look into how they’re made and the ingredients, but it’s also important to think about what the dishes reveal about each country’s climate and culture.
Home cooking is extremely helpful for understanding a country’s people and their daily lives.
Someday, when you travel, the knowledge from your project will help bring you closer to that country.
