[For 4th Graders] Fun Independent Research Ideas You Can Do With Everyday Materials
Many fourth graders are probably struggling to choose a summer break independent research topic that’s “fun but not too difficult.” In fact, you can create a project that makes your friends say “Wow!” using simple experiments and crafts with everyday materials.
Here, independent research pros introduce exciting ideas you can dive into, like a shiny coin experiment with 10-yen pieces, making kohakutou (amber sugar candy), and crafting hydrangeas.
Plus, everything from preparation to record-keeping is explained carefully, so you can take on the challenge with confidence.
Find a special independent research project that will become a lasting summer vacation memory!

[4th Grade] Fun Independent Research Ideas (21–30) Using Everyday Materials!
Sparkling hourglass
Let’s make a cute, sparkly hourglass that doubles as interior decor.
Prepare two small bottles, glitter to use as sand, a clear plastic file sheet, and decorative parts.
Cut the clear file slightly larger than the bottle opening and make a hole in the center for the glitter to pass through.
Attach tape and half-cover the hole, then glue it to the bottle.
Add the glitter and glue on the other bottle.
Finish it off cutely with decorative parts.
After adding the glitter, be careful not to turn it over until the adhesive has dried.
What happens if you microwave soap?
A simple experiment you can try right away if you have bar soap lying around at home or in your stock: what happens when you microwave soap? Put a bar of soap in the microwave and turn it on—you’ll be amazed by the fun sight! You can still use the soap afterward, so report on how it feels to use.
You might also capture the changing shape in a video or photos as it heats in the microwave.
It’s an experiment recommended from an ecology and SDGs perspective as well.
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!
Let’s try making a squeeze
A squeeze toy you can’t stop touching.
They’re sold at variety stores and 100-yen shops, and the food-themed ones look so cute that you can’t help wanting them.
How about making one yourself? Using a sponge and acrylic paint, you can make donuts or corn dogs that give a satisfying crunchy sound, or use water slime to create a candy apple with an addictively squishy feel.
Making squeeze toys also makes for a great summer science project.
Let’s try making ice cream that doesn’t melt
Ice cream you could eat every day on a hot day.
This experiment might change the idea that ice cream always melts quickly.
Let’s start by making ice cream! The ingredients are mostly the same, but for one batch we add agar or kanten powder.
When you place the agar-added ice cream next to the regular one… amazingly, the one with agar doesn’t melt.
Regular ice cream starts to melt when the temperature is above 20°C, but the agar-added version won’t melt unless it’s heated to over 70°C.
Fizzy Ramune Experiment
Why not try making fizzy ramune tablets for your summer break science project and enjoy their colors and sounds when dropped into water? After thoroughly mixing ingredients like powdered sugar, cornstarch, and food-grade citric acid, add food coloring to make them visually fun.
Press the mixed dough with two spoons to shape it just right.
Let them dry for about half a day to finish the ramune.
When eaten, they fizz in your mouth, letting you experience the curious chemical reaction of carbonation.
It’s a safe project even for children, using the carbon dioxide produced by the reaction between lemon juice’s acid and baking soda.
You can boost originality by changing the colors and flavors.
It’s a great idea for learning chemistry with familiar materials.
Let’s learn about sugar crystallization while making canelés.
Let’s make an experimental piece using a canelé mold for sweets.
Put powdered gelatin into a container filled with water and heat it in the microwave.
After heating, add sugar, color it with edible food coloring, and heat it in the microwave again.
Pour it into the canelé mold, and once it sets, remove it from the mold.
Your beautiful, colorful sugar canelés are ready.
At first, they look jiggly, but after a week, the sugar crystallizes and they turn into sparkly, crystal-like pieces.
You can enjoy watching the sugar change over time.
