[4th Grade] Fun Independent Research Ideas Using Everyday Materials (71–80)
Snow globe made from an empty bottle
Many people have probably received or bought snow globes as souvenirs or gifts.
Why not try making one with an empty jar? It’s easier than you think, and the result is beautiful and soothing.
All you need is an empty jar, a melamine sponge, liquid laundry starch (or thick laundry glue), small figurines or similar parts, and some glitter.
You can get them cheaply at a 100-yen shop.
First, attach the melamine sponge to the inside of the jar lid, then glue the figurines or other parts onto the sponge.
Put glitter into the jar itself, add laundry starch and water, mix, and screw on the lid—that’s it!
a picture from the story
When drawing, choosing a theme is important, and some people may struggle with that and find it hard to get started.
For those who aren’t good at deciding on a theme, a recommended approach is to use a story as a reference and create your artwork from it.
Freely choose a narrative, find a scene you like, and express it in your own way through your art.
Because cover illustrations and interior artwork can influence you, it takes skill to see how far you can distance yourself from them and how much originality you can bring.
Try to visualize the setting of the story and make a habit of expanding your imagination from there.
smart ball
Smart Ball is a playful craft that lets you build your very own game while getting excited about the motion of a rolling marble.
Cut lumber to fit a perforated board to create a frame.
Add an incline beneath the board so the marble rolls more easily.
For the launcher, use nails and rubber bands to make a pull-and-release mechanism that shoots the marble.
Attach a plastic sheet on top of the board to enhance the sound and feel as the marble rolls.
Place small pegs called dowels to add unpredictability to the marble’s path.
With creative targets and decorations, you’ll have a one-of-a-kind original Smart Ball game.
It’s a fun way to nurture creativity and observation skills as you play.

Cardboard 3D craft
Three-dimensional creations using single-faced corrugated cardboard make the most of the material’s qualities depending on the direction and shape of your cuts.
If you cut along the direction of the flutes, the cardboard bends easily; by changing the cutting direction, you can form pillar-like shapes.
Cut long strips and coil them or make rods to combine into towers, arches, or animal bodies—shape them freely.
Connecting multiple parts in three dimensions results in sturdy works.
Painting the surface or adding patterns enhances the finish.
Sculptures born from everyday materials convey the depth of making and the freedom of imagination.
Cardboard garbage collection truck
Let me introduce cardboard garbage collection trucks.
There are different types of garbage trucks, and their movements and installed parts vary.
All of the trucks being introduced are made using cardboard.
By paying attention to details—such as changing the shape of the emergency stop switch section, recreating the tail lamps with plastic sheets, and writing the manufacturer’s name—you can complete a garbage truck that looks just like the real thing.
Understanding the movements and features of each type of garbage truck also makes it easier to imagine the materials you’ll need to prepare.
Be sure to try making a garbage truck in your own style.
Cardboard vending machine
Let’s introduce a cardboard vending machine that looks just like the real thing.
Insert a coin and press a button, and a drink will come out from inside.
Gather the materials—milk cartons, cardboard, bubble gum, rubber bands, paper clips, plastic sheets, tape, glue, a ruler, scissors, and a utility knife—and let’s get building.
We’ll start by making the internal parts of the cardboard vending machine.
The key is to carefully measure each part and cut it to the correct size before assembling.
Measure the base cardboard as well to ensure it’s the right size to hold the drinks, then build accordingly.
It also sounds fun to make your own original drinks!
Marble Maze
Let me introduce a marble maze that’s so much fun to roll around.
Get your materials ready: a plastic board, colored construction paper, colored pencils, a ruler, a cutting mat, scissors, double-sided tape, clear tape, a ballpoint pen, and marbles.
Cut the plastic board to create the base shape of the maze.
It’s best to assemble the base by attaching pieces around the edges.
For the maze course, cut the board and adjust the sizes as you build.
Create traps by cutting construction paper and attaching them along the course.
Adding tunnels will make it even more exciting.
Roll your marble and enjoy aiming for the goal!
