Research and summarize about typhoons

[Independent Research] Are Changes in Air Pressure a Massive Source of Energy? The Mechanism Behind Typhoon Formation! [Yukkuri Explanation]

You learn about weather changes and typhoons in fifth-grade science, right? In that case, how about researching typhoons more deeply and putting together a report? Specifically, you could look into how typhoons form and where they come from, where they move to and what happens to them in the end.

There’s still a lot we don’t know about typhoons.

You could also investigate the strength of typhoons and the damage they cause, and use that information for disaster preparedness.

That would make your independent research even more meaningful.

Making salt crystals

Make salt crystals!!

A science project that amazes you with “I can’t believe something this beautiful can come from something you eat,” thanks to its jewel-like appearance, is making salt crystals.

You add a large amount of salt to hot water, and as you keep adding it, the salt eventually stops dissolving.

Let that saturated solution cool, filter it, and leave it for a while—salt crystals will form.

By the way, if you make saltwater the same way and place the formed crystals back into it, you can grow them larger.

Why not try and see how big you can make them?

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!

Handmade fireworks

Nagasaki City Science Museum: Let's make sparklers!

Fireworks are an essential part of summer, aren’t they? Instead of just buying store-bought ones, how about trying to make your own? The plan is to make sparklers: you mix oxidizers, fuels, and flash agents—the basic components of gunpowder—and wrap the mixture in paper.

Since they burn with a crackling sparkle, be sure to prioritize safety while experimenting with the amounts and wrapping methods to make them last longer.

The way you apply the powder can cause uneven burning, so staying focused while you work is also an important point.

Specific gravity experiment: “Rainbow Juice”

[Science × Sweets] Rainbow Juice Using Liquid Density [At Home]

It’s a juice with a mysterious, rainbow-like look, where beautiful layers of color appear in a single glass.

The key is the amount of sugar added to each color, using differences in liquid density to build the layers.

You’ll make three colors—red, yellow, and blue—varying the sugar content, and pour them into the glass in order from heaviest to lightest.

While creating some blended transitions between layers, it’s important to pour slowly over the back of a spoon so the colors don’t mix completely.

As-is, it would just be sugar water, so I also recommend adding flavorings or similar ingredients to make it taste good.

Experiment on the action of flowing water

Kimie Gangi, 5th Grade Science: “The Work of Flowing Water and Its Relationship to Water Volume” — Experiment Methods and Results #EducationalContent

In fifth grade, I think you also learn in class about the work of flowing water, such as erosion, transportation, and deposition.

Let’s actually observe these processes through an experiment.

For the method, build a slope out of collected soil, make a channel for water, and run water through it.

Try observing how erosion, transportation, and deposition actually appear, whether these processes change depending on the amount of water, and whether the way they appear differs between a straight channel and a curved one.

Test various conditions and summarize your findings in a report.

Let’s make kohakutou (amber sugar)

[Independent Research by a Former Private Tutor & Cram School Instructor Mom] Easy! Make Kohakuto (Amber Candy) for a Tasty Science Project

How about choosing kohakutou—beautiful and cute to look at, and delicious to eat—as the theme for your independent research project? It takes time, but you can summarize the changes over that period as your research findings.

Kohakutou is easy to make: dissolve sugar and agar in water, transfer the mixture to a container, add color with food coloring or shaved ice syrup, then once it sets, cut it and let it dry.

Depending on how much it dries, the texture will range from bouncy and soft to crisp.

You can record which number of drying days you found the most delicious and summarize your results.
