Paper chromatography

Paper chromatography [FAMIC]

Chromatography refers to a method for separating mixtures, and paper chromatography is a type of chromatography that uses water and filter paper.

Although chromatography might sound like a formal chemistry experiment, it’s actually easy to try as a hands-on science project.

One simple activity is to use paper chromatography to separate the inks of water-based pens.

Water-based pen ink is made by mixing various colors; for example, when you separate green ink, you can see that it’s composed of multiple colors.

The method is simple: color a coffee filter with a water-based pen, then dip it in water and leave it.

The ink will separate as if it’s bleeding, revealing which colors were mixed.

Try separating and observing different colors, or investigate whether the mixture of colors differs between brands even for the same ink color.

Gemstone polishing experience

The item that polishes ordinary stones into gemstones was just too amazing

For your summer vacation independent research project, how about trying a gemstone polishing experience? When you think of gemstones, you probably picture something sparkly, but in fact, raw gemstones have rough surfaces and look like ordinary stones.

However, by polishing them, they begin to shine brilliantly.

Start by flattening the surface with a file, then use polishing papers in order from coarse to fine.

Apply a finishing powder and polish, and finally rinse it clean with water—that’s it! Compare the rough stone before and after polishing, and take photos of each polishing stage to compile into your report.

Observation of Rivers and Landforms

[Science] Landforms Created by Rivers and Their Functions

The actions of flowing water—erosion, transportation, and deposition—are expressed as landforms around rivers.

For example, deltas, which are often seen near river mouths, are landforms created by deposition.

Using the internet, books, or maps, investigate places where these landforms can be found, then visit them to observe directly.

If you take photos and also record surrounding conditions—such as the river’s shape and how the water flows—you may discover patterns you hadn’t noticed before and deepen your understanding of how flowing water works.

Check food labeling

[Quick 2-Minute Guide!] Check the Correct Food Labeling

In fifth grade, students learn about food labeling in home economics.

Food labeling refers to the information on the packaging of commercially sold foods, such as ingredients, best-before dates, use-by dates, and nutrition facts.

Observe the labels on foods around you and list what information is provided.

Then, put together a report on various aspects of food labeling, such as whether there are differences between labels on fresh foods and processed foods, what the difference is between best-before and use-by dates, and what kinds of food additives and allergen information are listed.
