Trying to refine salt from seawater
How about trying to make salt from seawater? If you bring some seawater back when you go to the beach during summer vacation, it’s easy! All you have to do is strain the seawater with a coffee filter and then boil it down.
Little by little, the water will evaporate and you’ll be left with just the salt.
It could also be interesting to record how much salt you can produce from a certain amount of seawater and calculate the salinity from that! If you put the steps together in a notebook with photos and compile the data, it would make a perfect independent research project!
Making insect repellent spray
When playing outside in the summer, insect repellent spray is just as important as sunscreen.
It’s an essential item to avoid discomfort later! Here, we’re introducing a DIY insect repellent spray you can make with just three ingredients.
It only takes about 10 minutes to make, so it’s an easy science project even for lower elementary grades.
The ingredients are peppermint oil, water, and rubbing alcohol (ethanol).
Put the peppermint oil and ethanol into a container and shake well to mix.
Then add the water and shake again in the same way, and you’re done! Please summarize the steps and key points, such as the order in which to add the ingredients, when you write it up.
Paper chromatography
Paper chromatography is a method of separating substances using paper.
There are various approaches, but it’s perfect for a simple science project because you can easily try it with just a coffee filter and water-based markers.
The procedure is to mark the coffee filter with a water-based marker, then place the filter in water.
The filter will gradually draw up the water, and the ink from the marker will separate.
For example, black marker ink is made by mixing multiple colors, and with paper chromatography you can separate those mixed inks.
Try different colors, and see whether you can separate substances other than water-based markers as well.
Hydrostatic Pressure Experiment
The underwater world is full of wonders, isn’t it? Here’s an experiment that focuses on water pressure.
If you’ve ever swum in a pool, you may have noticed that the pressure you feel on your body is different when you’re doing the crawl or breaststroke at the surface compared to when you’re diving deeper down.
To make this visible, let’s try an experiment using a plastic bottle.
If this much changes over just a few meters, then the water pressure at seafloor depths of hundreds of meters must be beyond imagination.
Comparison of tin can telephones made with various materials
Have you ever made a cup-and-string telephone? These days everyone has a cell phone, so you might not need a string phone, but it makes a great experiment for studying how sound is transmitted—so give it a try.
This time, instead of just making a string phone, we’ll run an experiment by swapping the connecting string for various materials and observing the differences.
It’s really interesting how the sound changes depending on the thickness and material.
It’s also a good idea to investigate why the way it sounds changes.
Exploring Global Warming Through Data
How about researching global warming, which has long been a matter of concern? By learning about how the Earth works and past trends, you may be able to contribute to environmental conservation.
Anyone can do it as long as they have the means to look things up, such as a computer.

Clouds with a plastic bottle
This is a method to learn about the principles of clouds using everyday items.
You’ll create clouds with a mechanism similar to real clouds, so think about what the underlying principle might be.
Since all the materials are common and easy to find, it’s convenient as well.
Give it a try!
