Candle Experiment

[Independent Research] A Fireball That Moves!? Candle Experiment [Do-It-At-Home Experiment] #003

This is a simple yet very interesting experiment using two candles and something to light them.

If you bring a lit candle close to another candle immediately after blowing it out, the extinguished candle will mysteriously relight.

The flame ignites the candle’s smoke, and the fire travels along the smoke back to the wick.

Factory tour

A full day of social studies field trips for adults and children — Goka Town — Kewpie — Yakult

These are factories that make the things we normally eat, drink, and use, and some of them will let you tour the production process if you apply.

Then, summarize what you learned from the tour and study how familiar items are made!

Let’s research endangered species

11 Extinct Animals

There are many kinds of animals and insects living around the world.

Among them, how about researching those whose numbers have decreased due to environmental changes and other factors? They range from rare creatures you may have never seen to animals familiar to us.

You might also look into the reasons their numbers have declined and those that have become extinct.

Let’s explore the shapes of sounds!

Patterns Created by Sound (Chladni Figures)

Spread salt over a taut sheet of plastic stretched across a bowl, then make a sound nearby.

The salt will move in response to the sound’s waveform and vibrations.

Collect data under various conditions—such as pitch, volume, and distance from the bowl—and examine the resulting patterns.

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.

Let’s make a battery-powered train that runs through a coil.

Summer science project: “Battery train running through a coil” [Research]

This is an experiment to make a curious device where a battery races through a coil.

All you need is copper wire, an AAA battery, a neodymium magnet, and a rod to wrap the wire around.

The steps are simple: wrap the copper wire around the rod to make a coil, attach neodymium magnets to both ends of the battery, and place the assembly into the coil—then the battery will start moving.

It’s an experiment that uses the right-hand rule, and the battery will keep running until its power is depleted.

It would be good to look into this rule as well.

Let’s try mixing water and oil.

[Science Project] Let's Mix Water and Oil!

This is an experiment where you prepare two liquids—water and oil—and observe what happens when you mix them.

It’s recommended to add food coloring to the water so it’s easier to tell them apart when mixed.

Add a few drops of water into the oil and observe what state it takes, then stir the mixture and observe how it changes.

If you add dish detergent, which is used to remove grease, you might get a different result.

Try adding various substances and experiment.
