[I don't want to be like everyone else!] Recommended independent research topics for high school students
When it comes to summer break independent research projects, many high school students struggle to choose a topic.
Independent research can be especially time-consuming and challenging.
But don’t worry! Here, we introduce interesting independent research ideas recommended for high school students.
Some involve using fire or slightly more complex methods, so you’re sure to find something that interests you.
From experiments using familiar materials to hands-on crafts, there’s a wide range—from simple projects to those that take more time.
Dive in and turn your project into a fulfilling experience.
Have fun and learn a lot along the way!

[Stand Out from the Crowd!] Recommended Independent Research Topics for High School Students (41–50)
Foodtech
Food tech uses the power of technology to tackle food-related challenges such as global food shortages and hunger, as well as labor shortages in agriculture and fisheries.
Specifically, efforts include creating new foods through technology and deploying robots in understaffed areas to work in place of humans.
Other initiatives involve making meat dishes using beans and other substitutes, and researching long-term preservation to reduce food waste.
If you love eating or are interested in food, why not look into these research efforts as a way to help save the world—and the future—through food?
Schlieren phenomenon
An experiment on the Schlieren phenomenon.
Prepare coarse brown sugar, a wire, an alcohol lamp, and matches.
Light the alcohol lamp and heat the wire.
Next, when you try to insert the heated wire into the brown sugar, the heat melts the sugar and the wire goes in.
If you leave it for a while, the surrounding area solidifies and the wire remains fixed in place.
There are various other experiments for the Schlieren phenomenon, such as putting candy in water and observing how it dissolves.
pulsejet engine
There is an engine called a pulse jet, which has a simple structure.
This experiment recreates its mechanism using an empty bottle and fuel alcohol.
While fine-tuning the amount of alcohol and the size of the holes, let’s consider how to obtain the best results.
Since you will be using a power drill and fire, pay close attention to safety and be sure to conduct the experiment only when a family member is present.
Investigate and summarize topics such as what adjusting the hole size means, the conditions required for engine ignition, and how to keep it running for a longer time.
Make carryable water
Have you heard of Ooho!? It’s water you can hold in your hand—you might have seen some YouTubers making it! And it’s not just “Wow, it’s water you can hold!! So fun!”—it’s also getting attention as a new kind of packaging that could reduce plastic bottles.
It’s amazing that we can create eco-friendly solutions through chemistry, right? You use sodium alginate and calcium lactate; when these two react, they form a gel-like layer around the water.
If you carefully write up how that reaction works, you’ve got a complete science project report!
phase of sound
In simple terms, the phase of a sound is how the sound changes over a given period of time.
Put even more plainly, it’s the waveform—the wave of the sound itself.
When you’re wearing earphones and play exactly the same sound from both the right and left channels, it will seem to come from the center.
I encourage you to look into how the perceived position of a sound works and how shifts in phase change what you hear.
When two sounds with exactly opposite phase meet, you can get the strange phenomenon where the sound is being produced but you hear nothing.
Highly recommended for music lovers.
Summary of the nature observation trail
When it comes to independent research projects, many people might think of creating reports based on experiments in chemistry or physics, but preparing for those can be a lot of work, and some people simply aren’t good at that sort of thing.
If you enjoy being in nature, try finding and documenting your own nature observation trail.
Exploring places where various insects, animals, and plants live and turning them into an illustrated map will look great and make the project feel like an enjoyable outdoor activity.
There are even nature observation trail competitions, so if you put real effort into it, it can become an excellent independent research project.
Aquarium
It’s also wonderful to try your hand at aquariums, which have become popular in recent years.
An aquarium is a setup that houses living creatures in a tank.
For example, a tank with fish swimming in it is an aquarium, and a tank with shrimp is also called an aquarium.
Adjust the placement of objects, aquatic plants, and lighting to create an aquarium that’s uniquely your own.
One of the charms of this idea is that, once it’s finished, you can display it at home.
A related variant we recommend is a moss terrarium, where you cultivate moss.
