[For 4th Graders] Fun Independent Research Ideas You Can Do With Everyday Materials

pull-back car

A toy that runs on rubber power! 'Corrugated Plastic Pull-Back Car' [Easy Craft] #HandmadeToy #Craft #SummerVacationCraft

This craft lets you experience the fun of a car you built yourself zooming forward powered by rubber bands.

Cut corrugated plastic (plastic cardboard) to match the size of the car body.

For the wheels, use bottle caps: make a hole in the center, then pass a bamboo skewer through to create the axle.

If you firmly attach this to the body with hot glue, it will start to look like a real car.

Hook a rubber band onto the rear axle and wind it by turning the axle forward, and you’re ready to go.

When you let go, the car surges ahead under the power of the rubber band.

You can freely design and color the body, so you can get particular about the appearance too.

Using everyday materials and a simple mechanism, it’s a hands-on project that’s both fun to build and a great way to learn, delivering dynamic motion.

Running Robot

Making Things | Exciting Karakuri Craft: Running Robot Edition | Toyota

An exciting craft! Let me share an idea for a running robot.

Some of you might want to do a craft project but can’t think of a good idea, right? This time, let’s make a running robot that uses a windshield wiper mechanism.

You’ll need a rectangular plastic bottle, bamboo skewers, straws, thick paper, cardboard, plastic bottle caps, rubber bands, and so on.

It’s a great idea that lets you learn how a wiper mechanism works through crafting! Give it a try!

Transformable miniature house

For a summer vacation craft! How to make a miniature house that can be freely transformed

Let me introduce a cute, transformable miniature house.

Using cardboard, choose the coverings for the ceiling, floor, and walls as you build each room.

The key is to keep in mind the kind of room you want to create while you work.

Try stacking rooms or changing the combinations to make a miniature house that’s uniquely yours.

By making the wall coverings with colored paper or using patterned paper for the miniature house, you can add originality and have even more fun.

Let’s make dinosaur fossils

[Elementary School Craft] Let's Make a Fossil

Let’s make some exciting dinosaur fossils! First, think about what kind of fossil you want to create, then draw your fossil illustration on a sheet of foam board (styrene paper).

Cut out the fossil shapes with scissors.

Glue the cut foam pieces onto cardboard to form your design.

Paint it with acrylic paints.

When it’s finished, attach a decorative ribbon to the back so you can display it.

It’s also a good idea to round off the corners of the cardboard.

Have fun creating your very own original fossil!

A study on easy ice cream you can make in one minute

@nonno.chan

Summer vacation independent research, part two! Ice cream made in 1 minute using the power of chemistry. I’d be happy if you find it helpful!#Summer VacationIndependent Researchtranslation#HomemadeIceCream

♬ 3 minutes cooking style pop / cooking / sweets(957554) – ArcTracks

Have fun with it! Here’s an idea for a simple ice cream experiment you can make in just one minute.

Not many people have actually made ice cream themselves.

How about trying a fun and easy experiment where you can also enjoy delicious ice cream? All you need is milk, sugar, ice, salt, and resealable bags.

The steps are simple and easy to follow, so kids will likely jump right in! And since this is for learning, don’t forget to keep records of what you do!

Fossil making

At-Home Kids’ Science Class (Upper Grades): “Let’s Make Fossils!”

Get hands-on with shells! Here are some ideas for making your own “fossils.” We often hear that real fossilization can take over ten thousand years.

When dinosaur bones or ancient life fossils are discovered, they’re frequently featured in the news and media.

This time, let’s use shells to create specimens that look just like fossils! In the video, we clearly explain each step of the specimen-making process.

Take this opportunity to give it a try!

Sound experiment

[Environmental Experiment School] Let's experience how sound travels through 'things'

Learn how sound travels! Here are some ideas for sound experiments.

What comes to mind when you think of sound? You’re surrounded by all kinds of sounds, aren’t you? This time, let’s deepen our learning with the theme of sound.

In the video, it seems you can learn about what sound is and how people perceive it differently.

By studying the properties of sound, you might make new discoveries in your daily life! The experiments feature ones using test tubes and ones using different materials.

Give them a try!
