[For First Graders] A Collection of Science Project Ideas Using Everyday Materials

Many first graders struggle with their summer vacation projects and crafts.

It’s completely understandable to feel unsure—“It seems hard,” “What should we make?” In this article, we introduce experiment and craft ideas that kids can enjoy.

From a fascinating experiment with floating vegetables, to postcards made from milk cartons, to colorful aroma stones—there are plenty of fun projects using familiar materials.

Enjoy them together as a parent and child, and make great summer memories!

Sparkling hourglass

[Easy Craft 🍉] How to Make a Sparkling Hourglass ❣️
Sparkling hourglass

Let’s make a cute, sparkly hourglass that doubles as interior decor.

Prepare two small bottles, glitter to use as sand, a clear plastic file sheet, and decorative parts.

Cut the clear file slightly larger than the bottle opening and make a hole in the center for the glitter to pass through.

Attach tape and half-cover the hole, then glue it to the bottle.

Add the glitter and glue on the other bottle.

Finish it off cutely with decorative parts.

After adding the glitter, be careful not to turn it over until the adhesive has dried.

lampshade

I tried making a lampshade! Perfect for a summer vacation project—my child and I had fun making it together 😊

Here’s a lampshade idea that also works as room decor.

Brush glue mixed with water onto an inflated balloon, then stick on small torn pieces of washi paper.

For sturdiness, layer the washi several times until the balloon’s color isn’t very visible.

Be sure to leave an opening where the light will go.

Since washi is white, use tissue paper if you want to add color.

Once it’s completely dry, pop the balloon and remove it, then secure a wire along the inside edge of the opening for the light to finish it off.

How to make a watermelon bar squishy

[Low-Rebound] How to Make a Watermelon Bar Squishy 🍉 Squeeze Toy 🏝 Summer Vacation Craft [Handmade Squishy]
How to make a watermelon bar squishy

Looks just like a real ice pop!? Juicy to the eye and satisfyingly squishy to the touch, the “Watermelon Bar Squishy” is an adorable handmade craft perfect for summer.

It’s an easy yet highly polished project, especially recommended for upper-grade girls.

Start with a sponge from the 100-yen shop and cut it into the shape of a watermelon ice bar.

Carefully paint a red–green–white gradient with acrylic paints.

Recreate the seeds realistically using black paint or clay.

A wooden stick works perfectly for the ice pop handle.

People are sure to say, “That looks delicious!” It’s cute to look at and fun to touch—give this delightful summer science/craft project a try!

Investigating how ice melts

Elementary School Independent Research: Experiment on How Ice Melts
Investigating how ice melts

This is a perfect experiment for a hot summer, using ice.

You don’t need any special materials, and it’s great that elementary school children can do it without adult help.

Prepare several ice cubes of the same size, plus items like paper towels, aluminum foil, an insulated bag, newspaper, bubble wrap, a towel, and paper plates.

Wrap the ice in each material and, at set times—after 30 minutes, 1 hour, and so on—observe how the ice melts over time.

Before you begin, make a prediction about the order in which they will melt, from fastest to slowest.

When you’re done, compare the results with your prediction and try to summarize why some kept the ice from melting as quickly.

Adding your own ideas to the summary makes it even better!

Vegetable Stamp Art

I tried making veggie stamps!!!
Vegetable Stamp Art

Many people are likely looking for easy science projects or crafts for lower elementary school students.

For you, we recommend “vegetable stamps.” Cut various vegetables, apply ink to the cross-sections, and make stamps.

Since each vegetable has a different cross-section, you could even turn it into a quiz-style project.

Using the stamps to create pictures is also a great idea.

Art with the “bleeding” of water-based pens

[Independent Research Festa 2022] Create art with the “bleeding” of water-based pens! Provided by: Misono Girls’ Junior High School
Art with the “bleeding” of water-based pens

Many children enjoy drawing and coloring.

Here’s a slightly unusual art idea: bleeding art with water-based markers.

As the name suggests, it makes use of how water-based markers bleed.

First, prepare filter paper or coffee filters.

Fold them into pleats and place dots in the center using water-based markers.

Then add water—the ink will bleed and a soft-colored flower will appear.

To dry them, use a hot plate, so be sure to work together with a parent or guardian.

Musical instruments made from empty cans

[WakuWaku-san’s Craft Class] Make “can instruments” out of empty cans—build them and play them! (We’re introducing two can instruments!)
Musical instruments made from empty cans

Let’s have fun making can instruments from empty cans.

Here, we introduce two instruments: an ocarina and another instrument that produces a scale alongside it.

Use an aluminum can for the ocarina and a steel can for the other instrument.

First, here’s how to make the ocarina.

Remove the pull-tab from the can, and tape a slightly thick straw to the mouth opening.

On the side of the can near the mouth opening, use a punch to make five holes spaced 2 centimeters apart.

Make one more hole at the top on the opposite side, and it’s done! For the other instrument, remove the can’s pull-tab and rub the bottom with something hard like a chopstick.

The pitch will change, so adjust it to the notes you want and line them up.
