Amazing discoveries with everyday materials! Fun summer vacation independent research ideas

Let’s dissolve the eggshell!

Summer science project: Make transparent eggs using vinegar [Research]

Let’s try an experiment where the hard eggshell seems to disappear.

Take an egg, wash it well, pat it dry, and submerge it in a container filled with vinegar.

After about two days, the once pure-white shell will appear to have vanished.

When you take the egg out, there’s no hard shell; instead, it feels squishy, like a rubber toy ball.

By the way, be careful—eggs used in this experiment aren’t safe to eat!

Observation and experimental results on apple discoloration

Independent research! Observation and experiment results on apple browning

When you cut an apple and leave it out, the cut surface starts to discolor, right? Let’s observe that discoloration process.

We will monitor 11 conditions over time: a plain (untreated) apple, wrapped in plastic wrap, soaked in vinegar water, sugar water, salt water, honey water, milk, lemon water, a carbonated drink, plain water, and stored in the refrigerator.

Let’s compile a report on which one discolored the fastest and which one stayed the freshest-looking!

Keeping/storing a rhinoceros beetle as a pet

Revenge! Keeping a pair of sun beetles! A summer vacation science project!

Speaking of summer insects, rhinoceros beetles come to mind, so how about researching and observing them? If you go to a home improvement store or a pet shop, you can buy not only rhinoceros beetles but also rearing kits and food.

You can keep and observe two males together, or keep a male and a female as a pair.

If things go well and they lay eggs and overwinter successfully, you can raise many rhinoceros beetles the following year!

Gauss accelerator

Gauss accelerator

A Gauss accelerator is a phenomenon in which a steel ball, accelerated by magnetic force, launches the ball in front of it as if ignoring the law of conservation of momentum.

How about using this to create a project for an independent study? Try building various mechanisms and aim for a one-of-a-kind original course!

smart ball

Smart Ball [DIY, Independent Research, Craft, Doraemon]

Do you know the game called Smart Ball? It’s a Showa-era toy that looks like a pachinko machine: you launch a ball onto a slanted board, thread it through the pegs, and try to land it in the scoring slots at the bottom to compete for points.

Let’s try making one ourselves! Use a rubber band as the power to shoot the ball, then hammer in lots of nails to create the ball’s path.

You can also draw illustrations on the board if you like!
