Elementary School Students: Simple One-Day Science Project and Craft Ideas

Experiment to make butter

Experiment to Make Butter – High School Biology Lab

Butter makes all sorts of foods delicious—spread on bread, melted over baked potatoes, and more.

Did you know it can actually be made with a very simple process? The main steps are to pour chilled heavy cream into a sterilized container and shake it vigorously for 15 minutes.

The liquid will separate and turn into solids—the solid part is unsalted butter.

Mix in salt, and you’ve got butter! Shaking for 15 minutes is surprisingly hard work, so it might be a good idea to do it while watching TV.

Let’s also summarize why butter forms in the first place.

Let’s make a tornado bottle

[Independent Research] Let's Make a Tornado Bottle!

This is a fun, visually engaging experiment that uses scientific principles to recreate a rarely seen “tornado.” All you need is a plastic bottle and some detergent, making it easy to set up.

By measuring and observing variables like the number of spins and the duration, it can also be used for an independent research project.

Although it’s on a plastic-bottle scale, creating your own tornado is a rare experience—why not give it a try?

Cute seasonal decorations and keychains

Using shrink plastic, fluffy pipe cleaners, and clear stickers, you can make seasonal decorations and keychains.

Cut the shrink plastic into any shape you like, then use a single-hole punch to make holes around the edges for threading the fluffy pipe cleaners.

After threading the pipe cleaners, stick clear stickers onto the transparent area in the center.

You can add a chain to make it a keychain, or hang it with a string to turn it into a suncatcher.

Swapping out a seasonally themed keychain for each season is stylish and delightful, isn’t it?

The World of Masks

[Elementary School Craft] The World of Masks

Why not make a free-form mask and transform into a different persona? It would be so much fun to express your emotions—fear, joy, and more—by turning them into a mask.

First, punch holes where the eyes go in a sheet of colored construction paper in your favorite color.

It’s also fine to have no holes at all, and to use any shapes you like.

Then freely cut out facial features, fangs, horns, and more from origami paper, and attach them with cellophane tape.

Finally, draw patterns with a felt-tip pen to finish.

It sounds really fun to express your transformed self with a mask, doesn’t it?

Handmade toy from an empty snack box

[Elementary School Summer Vacation Crafts/Independent Research] Handmade Toys Using Empty Snack Boxes 🌻 #SummerVacationCrafts #IndependentResearch #Crafts #EasyCrafts #PlayAtHome #HandmadeToys #DIY

Make it with an empty snack box! Here’s how to create a pom‑pom shooting game! First, prepare an empty box that once held something like Choco Pie.

Reinforce the back by attaching a wooden stick so the lid can stay open.

Next, glue wooden sticks to the top and bottom of a wooden clip and wrap a rubber band around it.

Attach a plastic bottle cap to one end, and fix the other end to the back of the box.

Finally, stick a few small paper cups inside the box wherever you like, and you’re done.

Set a cotton ball in the bottle cap and launch it with a pop—have fun playing!

Surprising Craft

[Elementary School Craft] Surprise Craft!!!

An unexpected surprise! Here’s a craft project full of excitement that sparks curiosity.

At first glance, it looks like an ordinary envelope, but when you open it—“brrrriip!”—it makes a ripping sound! The method is simple, making it perfect for a summer vacation project.

First, prepare a bag handle, rubber bands, and a ring like the kind used for word-card binders.

Attach rubber bands to both sides of the ring, then tie them to the handle—and you’re done.

Wind the ring up and place it inside the envelope.

Feel free to draw on or decorate the envelope as you like.

The mechanism is that the ring spins when the envelope is opened, creating the sound.

It’s easy, so make a bunch and have fun playing with them!

Original watch

[Elementary School Craft] Original Clock

Why not try making a one-of-a-kind original clock using a DIY clock kit? First, draw diagonal lines on a canvas board and drill a hole where the lines intersect to attach the movement.

Sketch a few ideas, then paint your design with acrylic gouache based on those sketches.

To make the numbers stand out, you can create them with paper clay.

If you prepare a template that divides a circle into 12 equal parts, it will be easier to decide the placement of the numbers.

Once you finish painting, attach the movement through the hole you prepared in advance.
