Elementary School Students: Simple One-Day Science Project and Craft Ideas

I tried making a Super Ball.

[Free Craft] Recommended for Elementary School Kids!! A Metallic Super Ball You’ll Want to Make for Your Independent Research Project!!

Super balls are attractive for their colorful appearance and exceptional bounciness.

Because they absorb impact and rebound strongly, many of you probably remember bouncing them high when you were kids.

How about making your own super ball by hand? This time, we’ll use a store-bought kit, so there’s no need to gather materials individually—you can easily make one by following the included instructions.

Since the process involves using hot water and fine metallic powder, be sure to work together with an adult.

Create a one-of-a-kind original ball and have fun playing with it over summer vacation!

A truly usable cooler made from cardboard

[Experiment] I tried making a truly usable cooler out of cardboard!

Here’s a DIY cooler idea using cardboard, plastic bottles, a battery pack, and a motor.

First, cut three circular holes in the side of the cardboard box, each the same size as the bottom of a plastic bottle.

Insert and secure plastic bottles cut to one-third length into the holes, using the bottle neck ends.

On the inside of the cardboard, attach a propeller to the side opposite the bottles, and make small holes on both sides.

Mount the motor’s switch on the lid, place ice packs inside, and close the box to finish.

Decorate as you like with vinyl tape or similar materials.

The relationship between bread and sugar

Summer Vacation Independent Research: The Relationship Between Bread and Sugar — Elementary to Middle School, Science/Home Economics

Let’s explore how different amounts of sugar change bread by conducting a free research project on the relationship between bread and sugar.

Prepare several bowls, each containing the same amounts of cake flour, dry yeast, salt, butter, and water.

Vary only the amount of sugar in each bowl, then knead the doughs.

Carefully observe how the dough feels while kneading: what texture appears in doughs with more sugar, and what texture appears in doughs with less sugar? It might be helpful to record each stage—first proof, second proof, and baking—with photos to see how the dough responds at each point.

Enjoy this hands-on research project using everyday bread!

Let’s make rock candy

[Independent Research] Why Does Rock Candy Form? ~With Summary~ [Experiment Time]

Let’s try making sparkling, magic-like rock candy for a science project.

Prepare granulated sugar, water, sticks, wooden chopsticks, glass cups, liquid food coloring, and a pot.

Put the granulated sugar and water into the pot and simmer until it boils.

Wet the tip of the stick with sugar water and coat it with granulated sugar.

Pour sugar water and your favorite color of liquid food coloring into a glass cup, then sandwich the stick between a pair of chopsticks and set it so the stick doesn’t touch the bottom of the glass.

Cover with plastic wrap and leave it for 3 days to 1 week while observing.

Take photos and keep records to track any changes you see.

Surprisingly addictive study of shapes

[Math for a summer project!?] Surprisingly addictive! 3 free-research ideas using shapes

Here’s a great recommendation for anyone looking for an independent research project that blends learning with fun! How about studying shapes? Shapes are everywhere in daily life—origami, buildings, even sweets—so they feel familiar, and engaging with them in a playful way can help overcome anxiety about math and build confidence.

In your research, it’s important to narrow down your theme and explore it in depth, and to actually see, touch, and experience things firsthand.

Use the videos as a reference, find a topic that interests you, and give it a try!

Let’s make a flute

One-Day Science Project 6: Let's Make a Whistle

As a one-day science project, here’s a fun idea for making a simple flute.

Since this involves using fire, be sure to work with an adult.

Prepare three thick straws and flatten one end of each.

Use a lighter to gently heat the flattened end, then pinch the melted section with a clip to seal it.

After making all three the same way, blow into them—you’ll hear a flute-like sound.

The pitch changes with the length of the straws, so adjust them to create the scale you like.

I tried expressing sound with salt

[Sound LAB] Great for independent research! We tried representing sound with salt!

Let’s observe how salt patterns change with sound! Tape a black plastic bag over a bowl, then poke a small hole to keep the air pressure inside the bowl stable.

Wipe the surface with a damp tissue to remove static electricity, and sprinkle salt on top.

Now you’re ready—try making different sounds near the bowl, such as low and high voices.

The salt will respond to the sound and move, creating various patterns.

It will be helpful to note which sounds produced which patterns and to take photos, making it easier to compile your report.
