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.

desk lamp

Here’s an idea for making a desk lamp that uses a magnet-mountable LED light.
The stand is entirely wooden, and the arm is movable so you can adjust the angle.
First, think about what size you want and what kind of structure you’re aiming for, and try drawing a design plan.
Once the plan is ready, figure out the lengths and quantities of wood you’ll need and source the materials.
These days, you can even find small pieces of wood at 100-yen shops, so those might work as well.
One of the joys of woodworking is choosing the finish—whether to go for a natural look with varnish or oil, or paint it your favorite color—so definitely consider a variety of options.
Ice that freezes in 3 minutes

This is a science project where you make cool, tasty ice cream in a short time.
Put heavy cream, chocolate sauce, and chocolate chips in a zip-top bag and seal it tightly, then place it inside another larger bag filled with ice and salt.
Adding salt lowers the temperature of the ice, quickly freezing the cream inside the bag.
Wrap it in a towel and shake well, and in about three minutes the ice cream is ready.
The crunchy chocolate bits are fun, and the flavor is very satisfying.
Scientifically, the key is that salt lowers the melting point of ice, causing an endothermic process that absorbs energy and freezes the contents.
It’s an idea packed with both deliciousness and learning, letting you experience the relationship between cold and chemistry.
Sumikko Gurashi piggy bank

I’ll introduce how to make a Sumikko Gurashi piggy bank out of origami.
Prepare two sheets of origami paper and one small sheet, then let’s get started.
Use the small origami paper to make the 5-yen coin part.
Fold the corners toward the center, then fold the surrounding corners as well.
It will form the shape of a 5-yen coin, so draw the details with a felt-tip pen.
For the base piggy bank, fold the origami toward the center to create creases.
Following the creases, tuck the paper inward to form a square box.
Make two identical boxes; on one of them, attach the 5-yen coin and draw the face.
The key point is to change the color of the origami depending on the character.
Original handmade watch

When you go to a 100-yen shop or a handmade goods store, you can find just the clock movement for sale.
Let’s use that to make your own original clock! For the base of the clock, use a photo frame or a plastic plate.
Once you decide where to fix the movement, drill a hole.
Tighten the nut to secure the movement, and then decorate it to your liking.
Paint it, attach parts, or add glitter to make it sparkle—depending on your ideas, you’ll end up with a clock full of originality!
Candy Magnet

Let’s make a magnet that looks like a candy with twisted ends.
The materials and steps are very simple, so it’s highly recommended.
First, prepare strong magnets from a 100-yen shop, a plastic bottle cap, and a fabric scrap with a pattern you like.
Start by gluing the magnet to the back of the bottle cap.
Next, cut the fabric scrap to 14 cm by 10 cm, then fold back and glue three sides, leaving just one of the short sides unfolded.
Once the glue is dry, wrap the bottle cap with the fabric and secure it with glue.
Finally, to create the candy shape, gather and stitch the fabric at both ends with thread.
You’re done! Try making lots in different colors and patterns.
gel candle

At 100-yen shops, you can find a product called gel candles, and with them you can easily make homemade candles.
Gel candles are easy to handle, and you can even pour two different colors one on top of the other to create a two-layer candle.
The way the colors blend slightly between the layers also gives it a lovely look.
Plus, by placing items you like—such as colored sand, seashells, or dried flowers—into the glass before pouring in the gel candle, you can create a more stylish and original piece.
Give it a try and make one with your own sense of style.
Original T-shirts made with stencil printing

How about making your own T-shirt over summer vacation? We’ll use a technique called stenciling to create an original T-shirt.
You place a cutout of letters or illustrations on the fabric and paint over it with ink or other pigments.
Since you’ll wear the T-shirt, you’ll likely wash it too.
When stenciling on T-shirts or fabric, be sure to use fabric ink that won’t wash out.
While this can be a summer vacation homework project, it can also become a fun summer memory.
You might even make matching T-shirts for the whole family.
There are stencil T-shirt kits available online, so why not give them a try?
