3 easy science experiments that nurture the seeds of curiosity!

There are many science experiments that you can try easily at home. One of these is making “slime”, which is very popular among children and allows them to learn about buoyancy and static electricity.

It is fun to play with the soft and fluffy texture of slime!

Slime can be made with borax and PVA laundry glue. Borax can be purchased at pharmacies and online. Please keep in mind that borax is toxic so should only be handled by an adult.

<Items to be prepared>
Borax (6g)
6g of borax – 80ml and 60ml of 40°C hot water
80ml PVA laundry glue
1 pair of disposable chopsticks
Food coloring

<Procedure>
1. Mix 80ml of hot water + food coloring.
2. Put 60 ml of hot water and 6 g of borax in another container and mix to dissolve.
3. In a large container, mix 80 ml of PVA laundry glue with 1 ml of colored water.
4. While mixing 3, add the borax solution from 2 little by little, and mix quickly to finish.

How to draw a mysterious picture that floats on water

In this experiment, pictures float when they are released into the water. Parents should put a piece of cellophane tape on a board and have their child draw a picture on the cellophane tape with a whiteboard marker. Once your child is done with their picture, slowly place the painted board in the water at an angle and watch the picture on the cellophane tape peel off and float in the water. Make sure that the picture is filled in well, so it won’t fall apart and will peel off easily.

Moving butterfly wings! Learning about static electricity

This is a fun activity to enjoy during the dry season. Parents just need to prepare flower paper, construction paper, scissors, tissue and balloons, which can all be found at the 100 yen store.

Start by making the body and face of the butterfly out of construction paper. Then cut out the left and right wings out of flower paper and paste them on the construction paper. After inflating the balloon, rub it with a tissue and bring the butterfly close to it. The wings of the butterfly will stick to the balloon like magic. This is because the static electricity generated by the balloon makes the light flower paper stick.

Two experiments that help children learn science through food

Some experiments combine food ingredients and temperature changes to show how science works. The below experiments combine bananas and juice, two items that children love.

Drawing on a banana!

As you have probably noticed, banana peels contain polyphenols, and the damaged parts oxidize and turn brown. You can take advantage of this natural scientific process to make your own designs with a toothpick. Parents should choose a banana with a yellow, firm surface and make sure their child does not write too strongly. The design will appear after leaving the banana in the air for a few minutes. Parents should make sure to watch younger children when they are drawing so they do not get hurt.

Watching how juice freezes!

For this experiment, parents will need to prepare 200g of ice, 100g of salt, 50g of juice, a large and small bowl and chopsticks. Start by putting the ice and salt in a large bowl and mixing them well. Then put a small bowl on top of the ice and salt mixture and add some juice. Children will observe the beautiful patterns formed as the juice freezes. The experiment is based on the principle that adding salt to ice will cause the temperature to drop rapidly.

Science is full of questions and wonders. Many preschool programs for younger children incorporate science experiments and other STEAM activities. Attending these programs will not only help your child become interested in science but also help them develop their problem-solving skills and creativity.
