Wonderful independent research

Recommended for elementary school students' independent research! Experiment and observation ideas using everyday materials

Recommended for elementary school students who haven’t decided on a summer vacation independent research project yet! Choosing a topic can be tough, but in this article we introduce exciting ideas that will make you feel thrilled just reading them—from factory tours at candy makers to gemstone polishing, and even a DIY telescope you can build with materials you have at home! You’ll also find plenty of ideas you’ll want to tell someone about, like a curious experiment to check your ear age and a project to make water that’s both hard and soft.

You’re sure to find tips for independent research that use familiar items and are fun to try!

A fountain made with a plastic bottle

“The PET Bottle Fountain” is a science experiment suitable for upper elementary grades and above.

In this experiment, you increase the internal pressure of a PET bottle by leveraging how air volume changes with temperature.

The necessary materials include a PET bottle and a vinyl tube, among others.

Because the amount of water expelled varies with temperature, it can be interesting to calculate the pressure from the amount of water remaining inside the bottle.

Morse code

Independent Research: Let's Try Sending Morse Code!
Morse code

If you’re looking for a scientific experiment suitable for upper elementary school students, a Morse code experiment is recommended.

In this experiment, you send Morse code using electrical signals.

You’ll need materials such as a battery, enamel-coated wire, and aluminum plates.

Since building the device requires knowledge of electrical circuits, it’s best to get help from an adult.

Once the device is ready, try having a conversation with someone using Morse code.

Mysterious Ramen

Make mysterious ramen! It's also great for a summer vacation independent research project!
Mysterious Ramen

“Mysterious Ramen” is a hands-on science project where you can enjoy a tasty dish.

The soup of this ramen starts out blue, but when you add vinegar, it mysteriously changes to pink.

The ingredients include instant ramen with a light-colored broth (such as a salty flavor), red cabbage, vinegar, and more.

In fact, red cabbage soup changes color depending on acidity or alkalinity, so try observing that reaction.

Let’s observe the reflection of light

How about doing an independent study observing the properties of light? In elementary school science classes, you probably do experiments to confirm light reflection, but let’s dig deeper into that for your project.

Shine a flashlight inside a box to check the direction the light travels, place a mirror, and observe the angles of reflection.

It could also be interesting to compare the flashlight’s brightness with the number of reflections.

The Secret of Superabsorbent Polymers

[Easy Summer Vacation Science Project] The Secret of Water-Absorbing Polymers [Science Experiment]
The Secret of Superabsorbent Polymers

Superabsorbent polymer is a white powder-like substance that absorbs water, found in items like diapers.

This experiment involves adding salt to superabsorbent polymer that has fully absorbed water and become smooth-flowing.

You’ll surely be surprised by the results! You can get superabsorbent polymer online or at home improvement stores.

It can also be taken out of diapers, so it’s easy to obtain.

It only takes about an hour to do, making it a great choice for kids who want to finish their independent research project quickly.
