Lemon battery

[Science Experiment] Let’s Make a Fruit Battery! [At Home]

When you think of batteries, dry cells and smartphone lithium batteries are common, and I think you learn about fuel cells in school.

But have you heard of a fruit battery? You can generate electricity by inserting a zinc plate and a copper plate into a lemon.

Let’s also try summarizing whether it works with fruits other than lemons and with combinations of metals other than zinc and copper!

A battery-powered train running through a coil

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

This is an experiment often called the world’s simplest train: running a battery through a coil made by winding copper wire.

It uses magnetic force based on the right-hand rule, and it’s fascinating to see the battery move on its own.

While making the coil by wrapping copper wire around a pipe takes some effort, once that’s done, the experiment is easy—just attach magnets to the battery.

The orientation of the magnets on the battery and the direction you insert it into the coil are crucial for making it run.

Let’s also learn how it behaves when these are set incorrectly.

carbonated bath

[How to Make a Carbonated Bath] Effects and Method of a Carbonated Bath — Warming, Moisturizing, Cold Sensitivity, and Cleansing Effects Using Baking Soda and Citric Acid — [Chiba City Chiropractic Clinic “Kai”]

Some bath additives used in everyday baths produce bubbles when added.

This experiment is about creating that fizzy effect yourself.

All you need are baking soda and citric acid—it’s a simple experiment.

When you add citric acid after putting baking soda into hot water, carbon dioxide is generated.

You can sprinkle the powders directly to make a carbonated bath, but it might also be interesting to look into making bath bombs by adding other ingredients.

Carbonated baths aren’t just fun for the fizz—they also have practical benefits, such as promoting blood circulation and helping remove dirt.

Snow globe making

Fun for parents and kids ♡ Done in 15 minutes! Easy snow globe tutorial

During long vacations, we’re swamped with homework, independent research projects, and playtime.

It’s easy to put things off and run out of time.

That’s when this snow globe is highly recommended! The glitter and “snow” that slowly fall and sparkle inside the glass are beautiful, aren’t they? You can get most of the materials at a 100-yen shop: purified water, liquid glue, a hot glue gun, a jar, a sponge, decorations you want to put inside, and glitter.

It also doesn’t take much time, so it’s truly a strong ally for independent research projects.

Alternate turning response in insects

Maze Grand Escape! Alternating T-Maze (spontaneous alternation) experiment

I’m conducting experiments on alternation behavior, which is often observed in insects and other organisms.

Alternation behavior refers to a zigzag pattern in which, after turning right once, the next turn is left, and after turning left, the next turn is right.

With this tendency, pill bugs can navigate mazes effectively.

Other organisms that exhibit alternation include earthworms, cockroaches, paramecia, and sow bugs.

There’s also the BALM hypothesis; if you’d like to dig deeper, try looking that up as well.

Investigate the mechanism by which detergents remove dirt.

[Attention all good kids! Experiment!] Surfactants that remove dirt! #111

Detergent is an indispensable tool for removing dirt in situations like cleaning and laundry.

This is a study of the mechanism of surfactants—how such detergents actually remove grime.

Fill two containers with water, and mix detergent into one of them, then compare their interactions with dirt under various conditions.

Let’s test how the dirt is broken down and whether it transfers.

By taking a fresh look at a tool so embedded in everyday life, we can also learn how to use it more effectively by understanding what’s happening here.

The Irritation Stick made with 100-yen store items

@rollercoaster002

#Summer VacationIndependent ResearchInvention and ingenuityworkSimple craft#100-yen-shop100-yen shop craftsElementary school craftJunior high school student crafts#IrritationStickElectrical work

Original Song – Craft Team STARSS – Craft Team STARSS

Let’s make a steady-hand game using materials from a 100-yen shop and learn about electricity! The materials are: a foam brick, a personal safety alarm, aluminum wire, copper wire, and vinyl tape.

Remove the switch from the circuit board inside the safety alarm and insert and solder the copper wire.

Wrap the copper wire with vinyl tape to cover it.

Shape the aluminum wire however you like, insert it into the foam brick, and connect one end of the copper wire to it.

Now your steady-hand game is complete! When you touch the remaining copper wire to the aluminum wire, the safety alarm will sound.

If the alarm doesn’t sound, it means the electrical circuit from positive to negative isn’t connected.

Check it again.
