ice fishing
It’s a science experiment that looks difficult at first—ice fishing with a string—but it’s actually easy to do.
First, put some salt on a plate and place an ice cube on top.
Then lay a water-dampened string over the ice, and amazingly, you can lift the ice with the string! As the salt dissolves, it rapidly absorbs heat from the ice, lowering the temperature and freezing the damp string onto the ice.
That’s how the string freezes and sticks to the ice, letting you ‘fish’ up a piece of ice you wouldn’t normally be able to lift.
If you do a bit of extra research on how cooling makes the string stick, your independent research project will be finished in no time!
Making a PET-bottle microscope
A microscope used for science experiments… you can actually make one out of a plastic bottle.
To make it, cut the bottle, attach a slide to the mouthpiece, fill a hole-punched cap with glass beads, and put it all together.
It’s very simple.
As for how much it can magnify, see for yourself with your own eyes.
Let’s observe all kinds of things!
Investigate the principle of the siphon
A lot of high school students probably like coffee, don’t they? When you order coffee at a café, there are places that serve it not only by drip but also using a siphon.
How about making the principle of the siphon the topic of your independent research? A siphon moves liquid by using atmospheric pressure, and you can recreate the same mechanism with a bucket and a hose.
Binchotan charcoal battery
Can binchotan charcoal become a battery? This is a curious experiment.
Wrap binchotan charcoal with cooking paper and pour saline solution over it.
Then wrap aluminum foil around it, and your binchotan battery is complete.
If you connect a motor to the binchotan and the aluminum foil, the motor will actually turn thanks to the binchotan battery! Aluminum from the foil dissolves in the salt water and releases electrons, and when those electrons encounter air at the surface of the binchotan, electricity is generated.
You must use binchotan charcoal; otherwise, electricity won’t be produced.
If you only have regular charcoal, heating it with a burner will make it conductive!
Camera craft
Let’s try making a camera using a milk carton.
A camera is handy for taking photos and preserving memories.
It’s a simple version, but you can make it yourself.
You’ll use a milk carton, a plastic bag, a magnifying glass to act as a lens, and black construction paper.
First, cut off the top and bottom of the milk carton.
On one end, fold the edges inward about 1 cm on all four sides, then cover it with a cut piece of plastic bag and secure it.
Next, make a tube out of black construction paper that’s just a little larger than the milk carton, and fold in the edges on one end in the same way.
Fix the magnifying glass there, and then insert the milk carton you prepared earlier into the inside of the tube to finish.
Take it outside and experiment to see how it looks!
Investigate how color-changing drinks work
Do you know butterfly pea tea? It’s a vividly deep blue tea that has long been enjoyed in countries like Thailand and India.
Let’s make a color-changing drink with butterfly pea.
Brew a strong butterfly pea tea and sweeten it with honey while it’s still warm.
Pour it into a tea server filled with plenty of crushed ice, then add soda water to make a blue soda.
Next, add lemon juice, and in an instant, it transforms into a bright pink drink.

Let’s make cutlery from tree branches
Wooden cutlery is simple yet warm and charming, isn’t it? How about making your own wooden cutlery as a hands-on science project? Prepare a branch that’s larger than the piece you want to make and sketch the outline with a pen.
Then just use tools to carve the wood down.
It takes patience, but once the shape of the cutlery starts to emerge, the excitement will outweigh the effort.
Just be careful not to injure yourself, and give it a try!
