Cook home-style dishes from countries around the world

How to eat breakfast in India! It’s not naan. It’s chapati!

How about a tasty independent research project? In this project, you’ll explore home-cooked dishes from countries around the world.

Of course you’ll look into how they’re made and the ingredients, but it’s also important to think about what the dishes reveal about each country’s climate and culture.

Home cooking is extremely helpful for understanding a country’s people and their daily lives.

Someday, when you travel, the knowledge from your project will help bring you closer to that country.

Ice experiment using saltwater

Serious experiment!! Does the temperature change with the amount of salt?! Super-cold Experiment 2!! Great for independent research! / Denjiro Yonemura [Official] Science Experiments / cryogen

For independent research projects, it seems many people make crafts.

So why not stand out by doing a chemistry experiment instead? Many of you probably know that adding saltwater to ice lowers the temperature.

But does the degree of cooling depend on the amount of salt? How about this experiment, which allows for solid research with simple preparation—just ice, saltwater, and a thermometer?

solar water heater

Let's make a 'PET bottle water heater' that heats water with sunlight!

An experiment to see whether you can make hot water using sunlight—the simplicity of doing it with just a plastic bottle and paint is also a key point.

The procedure is simply to paint the plastic bottle with paint, fill it with water, and then monitor how the temperature changes under sunlight.

It’s important to thoroughly coat it with opaque paint, as if wrapping the transparent plastic bottle.

If you prepare various colors, you can observe temperature differences by color and find out which colors absorb more sunlight.

Japanese tea

[Independent Research] Become a Tea Expert in One Day—Teach Your Teacher, Too!

When time is limited, it’s hard to prepare anything unusual, isn’t it? So here’s something to try: a study of Japanese tea.

You should be able to find tea leaves at nearby stores like supermarkets or shopping malls.

Once you get some, explore how the flavor changes with water temperature and steeping time, and figure out the best way to brew it for the most delicious taste.

Since you’ll probably be brewing a lot of tea, having paper cups on hand will be convenient! You could also look for traditional Japanese sweets that pair well with tea.

Telescope Making

[Lunar Eclipse] Observe the night sky with a handmade telescope! [How to make one]

Let’s try making a telescope that lets you see distant objects large and clearly using materials that are easy to get.

Precisely because we’re building it with familiar items, it helps dispel the idea that it’s difficult while also teaching how a telescope works.

The tube section will be made from cardboard and a potato chip can, and the lenses will come from a magnifying glass and reading glasses.

It’s a simple process of mounting each lens inside the tube, but small touches—like surrounding the lenses with black paper—are also important.

It’s recommended to make small adjustments as you go, thinking about how to achieve a clearer image.
