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?

Homemade butter

[Independent Research] Homemade Butter You Can Make Just by Shaking Heavy Cream [Cooking]

This is a science project using store-bought heavy cream.

You’ll need heavy cream, salt, a plastic bottle, and some stamina! In this project, you pour liquid heavy cream into a plastic bottle and turn it into butter.

The method is very simple.

First, pour heavy cream into a 500 ml plastic bottle.

Next, add half a teaspoon of salt.

Then put the cap on the bottle and shake it nonstop! Keep shaking until it becomes solid! It’s quite tiring, but in the end you’ll have delicious butter, and your family will be thrilled!

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.

Try making yogurt from milk

Super Easy! How to Make Homemade Caspian Sea Yogurt (Successive Culturing)

Many high school students eat yogurt regularly, but few have made it themselves, right? So how about a science project where you make yogurt from milk? In fact, making your own yogurt is as simple as mixing store-bought yogurt into milk and letting it sit.

If you want to dig deeper, it might be interesting to investigate the conditions under which it fails.

Thinking about how to fly a paper airplane far

Easy Origami: How to Fold a High-Flying Paper Airplane

You might wonder, “Can something like this really be a free research project?”—but that’s precisely what this study of paper flight is.

There are many clubs across the country formed by paper airplane enthusiasts, and I’ve even heard that some engineering professors at universities research paper airplanes.

I think it’s quite interesting to analyze, from a scientific perspective, planes designed to fly far and planes that compete for longest airtime.

It’s well-suited for science-minded students, so if you’re a junior high schooler who likes math or science, give it a try.

By the way, it’s said that the first paper airplanes were made in China, where people used paper to make kites.

As expected from China’s 4,000 years of history!

Research how to make a paper airplane fly farther

How to fold a paper airplane that flies 100 meters, paper airplane folding Guinness record

Summer vacation is fun, but the thing that always trips us up is the independent research project or craft assignment, right? We also have to do our other homework, and we’ve got to go out and play! So here’s a project you can finish in one day.

This is a paper airplane everyone knows well… but it’s one that flies straight and far.

By getting creative with how you fold it and how you throw it, you can make a paper airplane that’s a little different.

How about explaining, with diagrams and text, how you came up with your ideas?

Let’s explore the mysteries of color

Independent Research Helper Kit: Explore the Wonders of Color (Gakken)

This is a science project where you closely observe the colors you usually see.

If it’s just observation, even lower-grade elementary students can do it, and upper-grade students can add analysis, so it’s a recommended project for a wide range of grades.

By using the three primary colors of light and layering sheets to create a color photograph, and so on, it becomes an experiment that produces interesting phenomena.
