Stargazing with a handmade telescope

[Lunar Eclipse] Observe the night sky with a handmade telescope! [How to make one]

How about doing astronomical observations with a telescope and turning that into your independent research project? You might think it sounds a bit boring, but here’s an idea: why not make the telescope yourself! It’s surprising, but you can build one using materials like a cylindrical empty snack box, black construction paper, reading glasses, a magnifying glass, and black vinyl tape—basically recycled items and supplies from a 100-yen shop.

Use your original telescope to observe the Moon and stars.

Hopefully, there will be a lunar eclipse or a meteor shower during summer vacation for an extra celestial show!

Haiku to remember

Haiku Elementary School Students Should Remember

Let’s learn through animation! Here are some haiku ideas you’ll want to remember.

Haiku has a rich history, and it’s well known that in the Edo period the three great masters of haikai—Kobayashi Issa, Matsuo Bashō, and Yosa Buson—composed remarkable verses.

This time, let’s learn seasonal words (kigo) from famous haiku.

Memorizing well-known haiku will help you discover the types of kigo and how to use them.

In recent years, haiku karuta (card sets) have also been available, so they’re great for anyone who wants to memorize while having fun!

Fizzy Ramune Experiment

http://www.lemon8-app.com

Why not try making fizzy ramune tablets for your summer break science project and enjoy their colors and sounds when dropped into water? After thoroughly mixing ingredients like powdered sugar, cornstarch, and food-grade citric acid, add food coloring to make them visually fun.

Press the mixed dough with two spoons to shape it just right.

Let them dry for about half a day to finish the ramune.

When eaten, they fizz in your mouth, letting you experience the curious chemical reaction of carbonation.

It’s a safe project even for children, using the carbon dioxide produced by the reaction between lemon juice’s acid and baking soda.

You can boost originality by changing the colors and flavors.

It’s a great idea for learning chemistry with familiar materials.

Let’s learn about sugar crystallization while making canelés.

http://www.lemon8-app.com

Let’s make an experimental piece using a canelé mold for sweets.

Put powdered gelatin into a container filled with water and heat it in the microwave.

After heating, add sugar, color it with edible food coloring, and heat it in the microwave again.

Pour it into the canelé mold, and once it sets, remove it from the mold.

Your beautiful, colorful sugar canelés are ready.

At first, they look jiggly, but after a week, the sugar crystallizes and they turn into sparkly, crystal-like pieces.

You can enjoy watching the sugar change over time.

Experiment where ham melts with kiwi

http://www.lemon8-app.com

Here’s a curious and fun science project using kiwifruit and ham.

Get your materials ready: kiwifruit, ham, paper, and felt-tip pens.

Place a sliced kiwifruit on top of a halved piece of ham.

By timing this setup, you can find out how many minutes it takes for the ham to start breaking down.

If you photograph the changes over time, your project will gain more depth.

You might discover something new by comparing heated kiwifruit with unheated kiwifruit.

Write down the purpose of the experiment and your results to complete your summer science project.

Butter Even Elementary School Students Can Make

@nonno.chan

I recreated a summer vacation science project I made a long time ago: homemade butter!#Summer VacationIndependent Research#HandmadeButterHomework#tiktoksummerbreak#meijiMeiji Delicious Fresh Cream

♬ 3 minutes cooking style pop / cooking / sweets(957554) – ArcTracks

Here’s a summer vacation science project idea for making authentic butter at home using heavy cream, salt, and a plastic bottle.

Put heavy cream and a pinch of salt into a plastic bottle, close the cap tightly, and shake it vigorously.

After shaking for a while, the contents will separate into liquid and solids.

This is the sign that butter and buttermilk have separated.

Pour off the liquid, cut the bottle open with scissors, and take out the contents—the butter is ready.

Spread it on bread to enjoy a special flavor that really lets you feel you made it yourself.

Watching the cream change teaches about dairy processing and fat separation.

The hands-on, energetic shaking is fun and gives a sense of accomplishment, making this a great idea for elementary school students.

Making Konpeito (traditional Japanese sugar candy)

http://www.lemon8-app.com

Let’s try making handmade konpeitō—colorful, cute sugar candies—for a summer vacation science project.

Boil sugar and water to make syrup, then gradually add small amounts of konpeitō cores; as you do, little spikes will slowly form on the surface.

By adding food coloring or flavorings during the process, you can customize the taste and color to your liking.

Even without special equipment, you can keep stirring and improvising with a frying pan or a bowl; it takes time, but the candies will gradually take on the characteristic konpeitō shape.

Because the results change depending on the temperature and timing of sugar crystallization and how you stir, it’s also enjoyable as a science experiment.

It’s a rewarding idea that nurtures both confectionery skills and observation.
