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.

Sweets Bath Bomb

[DIY] Cute Foamy Treats in the Bath ♡ Sweets Bath Bomb
Sweets Bath Bomb

A bath bomb you drop in the tub to enjoy bubbles and fragrance.

How about making bath bombs that look like fake sweets, with attention to appearance? The ingredients for bath bombs are baking soda, citric acid, cornstarch, aromatic oil, and food coloring.

Mix everything thoroughly, then mist with water to moisten until it holds together.

Next, press the mixture into silicone molds, let it set, and dry.

Then melt glycerin soap in the microwave, tint it with food coloring to mimic chocolate sauce, and drizzle it over the set bath bombs.

Try making a variety of sweet-inspired bath bombs—like donut shapes or chocolate shapes—and have fun!

Let’s make Colorful Joy!

Here’s a science project idea using dishwashing detergent that both kids and adults can enjoy! Let’s make “Colorful Joy” using the well-known dishwashing detergent Joy from the commercials.

The key to this project is combining the heavier, double-sanitizing Joy with the lighter, regular Joy.

Pour the heavier one into a glass or plastic bottle first, then gently add the lighter one afterward to create beautiful layers! You can try different color combinations, and it’s also lovely to add dried flowers in advance, like a herbarium.

The best part is that after you’re done, you can still use it at home as detergent!

An atmospheric pressure experiment using eggs

An atmospheric pressure experiment using eggs

This is an experiment where you can learn how air pressure works using a hard-boiled egg and a bottle! What you need are ice water, a bottle, hot water, and a hard-boiled egg.

Here are the steps: First, place the bottle in hot water to warm it up.

The bottle will become very hot, so when you take it out, be sure to use tongs or something similar so you don’t touch it directly.

Take the bottle out and place the hard-boiled egg over the mouth of the bottle.

While keeping the egg on top, put the bottle into the ice water to cool it down.

As you do this, the air pressure inside the bottle changes, and the egg gets sucked into the bottle.

Watching the egg get pulled in is fascinating and makes for a really fun experiment!

Fun-to-shake shaker

Here’s a fun shaker made from a plastic wrap core.

Use origami made of film.

Wrap double-sided tape around the core and seal one end with the origami.

From the other side, add beads or similar fillings and seal it the same way with origami.

Wrap washi tape around it, then cut the origami into strips and wrap them on.

Add googly-eye stickers and a mouth to finish! It’s fun to dance with to music, too.

Little kids will enjoy it, so be sure to make it together and have a great time!

You can make a fun maze with a cardboard wrap core! Here’s a simple way to do it.

First, cut construction paper to the length of the wrap core, and draw a maze on it using any writing tools you like.

Attach double-sided tape to the paper with the maze and wrap it around the core.

Next, cut a piece of wrapping film to about 5 cm and stick your favorite stickers on it—that’s it! Thread it through the wrap core to play the maze game.

If you make the construction paper removable, you can enjoy original mazes over and over again.

It’s also recommended to use stickers of your favorite characters to enjoy a themed world.

Fly! Core Rocket

Here’s how to make an easy “core rocket.” You’ll need a plastic wrap core, a toilet paper core, two rubber bands, and a straw.

First, cut the straw so it’s just a little longer than the opening of the toilet paper core.

Link the two rubber bands by looping them together.

Tape the rubber bands to the straw, then tape the straw onto the plastic wrap core with cellophane tape.

Once it’s set up so the toilet paper core can be launched, you’re done! Decorate the toilet paper core however you like to make your own original rocket.

Have fun and get creative!
