Wonderful independent research

Self-study that teachers will praise! Recommended independent science study ideas for 4th graders

10 years as a kindergarten teacher / elementary school teacher / junior and senior high school teacher / childminderkepiko
Graduated from Kunitachi College of Music, Faculty of Music (now: Department of Music Culture and Education, Early Childhood Music Education major). In elementary school, my homeroom teacher was Jun Kusaba, a game researcher. After graduating from university, I worked as a kindergarten teacher for 10 years and as an after-school childcare instructor for 7 years, then took a position as a music teacher at an international school in Singapore. In addition to music education, I engaged in activities that introduced Japanese culture, traditional games, and recreational activities, working with many children. Later, through freelance writing, planning, and editing at Shogakukan, I met many delightful adults and experienced the joy of communicating and sharing. Drawing on the perspective cultivated in the field of education and my experience as an editor, I provide practical information with an emphasis on both input and output, mainly in areas related to music and children. My hobbies include instruments, singing, handicrafts, toys, drawing, traditional games, the outdoors, and books. My special skill is spinning-top tricks.

Independent study in science can be a fun adventure for kids!

Here, we introduce self-directed science topics recommended for fourth graders that are sure to impress their teacher.

When you explore freely, learning becomes even more enjoyable.

Observe the nature around you, try simple experiments, and enjoy the thrill of discovering new things.

As your interest in nature and science grows, it’s also fun to share what you’ve learned with friends and family.

Please use this as a guide and let’s jump together into the exciting world of science!

Color-changing! Three-color jelly like shaved ice

[Independent Research] Mysterious! Color-Changing!? Shaved-Ice-Like Three-Color Jelly

Color-changing! Three-color jelly like shaved ice

Shaved ice is a summertime essential, and its vivid syrup colors are a big part of the appeal.

This is a three-color jelly that evokes that festive shaved ice and lets you enjoy color changes.

For coloring, we’ll use the cooking liquid from red cabbage.

We’ll observe how this pale purple liquid changes color when different ingredients are added.

Add lemon juice to turn it pink, baking soda to turn it blue, then mix in gelatin to set it.

Finally, place these on top of milk jelly to finish.

Let’s also look into why the colors change while making a delicious jelly.

Independent Research Helper Kit: Explore the Wonders of Color (Gakken)

Let's explore the mysteries of color

This is a science project where you closely observe the colors you usually see.

If it’s just observation, even lower-grade elementary students can do it, and upper-grade students can add analysis, so it’s a recommended project for a wide range of grades.

By using the three primary colors of light and layering sheets to create a color photograph, and so on, it becomes an experiment that produces interesting phenomena.

Anyone can easily make leaf vein specimens! [Serious Experiment Series]

leaf vein specimen

Plants have veins—like blood vessels in humans—that carry water drawn up from the ground to the tips of stems and leaves, and circulate the nutrients produced by photosynthesis.

How about turning those veins into a specimen? Heat a sodium hydroxide solution and place a leaf in it.

After about 20 minutes, take it out and gently brush the surface with a toothbrush; the leaf tissue will come off, leaving only the veins! You’ll likely think, “I can’t believe they’re spread out this much.” If you soak it with ink, it will look even more vivid!
