Learning physics does not always require sophisticated equipment or specialized laboratories. With a few simple materials available at home, it is possible to conduct fascinating experiments that can spark the scientific curiosity of young minds. This article explores various engaging and easy-to-do projects that allow for the exploration of the fundamental principles of physics while having fun.
Create a rainbow in a bottle
This experiment introduces children to the refraction of light. To create this colorful illusion, you will need a glass or plastic bottle, water, and a light source, such as a flashlight. Fill the bottle with water and aim the flashlight to project the light through the water. Children can observe how the light rays break apart, creating a rainbow.
Make an eggshell disappear
This experiment illustrates the principle of diffusion. Take an eggshell and immerse it in vinegar for 24 hours. The vinegar reacts with the calcium carbonate in the shell, resulting in its dissolution. At the end of this experiment, you will have a translucent membrane, which allows for the explanation of the notion of chemical reaction and the importance of acids and bases.
Make an iceberg
Think of a melting ice simulation to explore the concepts of state of matter. Fill a container with water and place a small bowl or cup inside. Add colored water with food dye into the bowl. Place everything in the freezer. As the ice starts to melt, observe the state changes and discuss the implications of melting glaciers in the context of climate change.
Make the pepper flee
This fun experiment demonstrates the surface tension of water. Fill a shallow plate with water and sprinkle a bit of pepper on it. Dip your finger in dish soap and then touch the surface of the water. The pepper will instantly move away. This explains how soap acts on surface tension, altering the properties of water.
The traveling water
Generate a flow of water using capillarity by placing one end of an absorbent paper in the water of one container and the other end in a second empty container. This demonstration shows how plants use the phenomenon of capillarity to transport water from their roots to their leaves. Children can see the water travel in a fun and visual way.
Create a lava lamp
A homemade lava lamp is a wonderful way to learn about density and the behavior of liquids. Fill a bottle with water about a third of the way, add a bit of oil, then a few drops of food dye. When you add baking soda, the bubbles of air created will make the dye rise and fall, mimicking the movement in a real lava lamp. This experiment helps understand the differences in density between liquids.
The unpoppable balloon experiments
This experiment is perfect for illustrating the principle of pressure. Take a balloon and poke it with a needle. You will find that the balloon does not burst as long as the pressure is evenly distributed, for example, by placing the balloon on a soft surface. This opens the discussion on atmospheric pressure and different types of forces.
Experimenting with water
Water is an excellent agent for exploring various physical concepts. For example, testing buoyancy with various objects to teach bouyancy and fluid dynamics. Children can conduct experiments to guess whether an object will sink or float in water and then verify their hypotheses to learn more about densitometry.
Understanding supercooling
This captivating experiment helps understand the principles of thermodynamics. Fill a bottle with distilled water and place it in the freezer without letting it freeze. When removed, a disturbance can cause the immediate solidification of the water, illustrating a state of supercooling. A discussion about the practical applications of this property, such as the operation of modern refrigerators, can follow.
For greater autonomy, children can document their observations and results in a logbook. This develops their critical thinking and understanding of scientific methods. Discovering physics through simple experiments at home opens new perspectives and nurtures their scientific curiosity for the future.

Physics is a fascinating science but often perceived as complex. However, it is possible to learn its principles in a playful and accessible way through simple experiments conducted at home. This article offers a range of scientific activities that will stimulate children’s curiosity while facilitating their understanding of physical concepts.
Create a rainbow in a bottle
With a few drops of food coloring, water, and oil, you can create a mini rainbow. By carefully adding the liquids, children can observe how different densities create a separation of colors, an excellent way to explain the concept of density and mixing.
Make water travel
This fun experiment will involve making water “travel” from one container to another using a piece of string or twine. This project allows for the explanation of the principles of capillarity and surface tension. Children will learn how liquids can move against gravity.
Make an iceberg
By mixing water, salt, and a bit of food coloring, you can create a floating “iceberg.” This experiment allows for discussing the salinity of water and the principles of bouyancy. Children will see how salt affects the density of water and, consequently, the ability of the object to float.
Make the pepper flee
A bit of pepper, water, and soap will allow you to conduct a captivating experiment. By adding soap to a container of water with pepper, children will observe how the pepper moves away from the soap. This is due to the surface tension of the water, sparking a discussion on the forces at play.
Understanding density with the floating egg
This experiment requires an egg, water, and salt. By adding salt to the water, children will see a floating egg. This illustrates the concept of density and the role that salinity plays in the bouyancy of objects.
Create a homemade lava lamp
With simply oil, water, food coloring, and effervescent tablets, you can create a lava lamp. This playful project clearly shows how liquids of different denses interact and layer on top of one another.
The unpoppable balloons
Use a simple technique to prove that, despite appearances, a balloon can be supported by a flame. By poking a lit balloon with a sharp object, children will learn how pressure and temperature play a role in the strength of materials.
The science of magical milk
A bit of milk, food coloring, and dish soap are the necessary ingredients to conduct an experiment that shows fascinating chemical reactions. Children will observe how soap breaks the surface tension of milk and creates colorful patterns.
