Fill the bottle with water and point the flashlight to project the light through the water. Children can observe how the light rays break apart, creating a rainbow.
Make an Eggs Shell 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 of the shell, leading to its dissolution. At the end of this experiment, you will have a translucent membrane, which allows for the explanation of the concept of chemical reaction and the importance of acids and bases.
Make an Iceberg
Think of a melting ice simulation to explore the concepts of states of matter. Fill a container with water and place a small bowl or cup in it. Add colored water with food coloring to the bowl. Put everything in the freezer. As the ice starts to melt, observe the state changes and discuss the implications of glaciers melting in the context of climate change.
Make Pepper Flee
This fun experiment demonstrates the surface tension of water. Fill a shallow dish with water and sprinkle some pepper on it. Dip your finger in dish soap, then touch the surface of the water. The pepper will instantly move away. This explains how soap acts on the surface tension, altering the properties of water.
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 capillarity to transport water from their roots to their leaves. Children can see 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 to about one-third of its capacity, add a bit of oil, and then a few drops of food coloring. When you add baking soda, the air bubbles created will make the coloring rise and fall, mimicking the movement in a real lava lamp. This experiment helps understand the differences in density between liquids.
Experiments with Unpoppable Balloons
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 distributed evenly, for example, by placing the balloon on a soft surface. This opens a discussion on atmospheric pressure and different types of forces.
Experimenting with Water
Water is a great medium to explore various physical concepts. For example, by testing buoyancy with various objects to teach about buoyancy and fluid dynamics. Children can experiment to guess whether an object will sink or float in water and then verify their hypotheses to learn more about densiometry.
Understanding Supercooling
This captivating experiment allows understanding 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 water to solidify immediately, illustrating a state of supercooling. A discussion about the practical applications of this property, such as the functioning of modern refrigerators, can follow.
For more independence, 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 nourishes their scientific curiosity for the future.

Make Water Travel
This fun experiment will have water “travel” from one container to another using a piece of string or yarn. This project allows for the explanation of the principles of capillarity and surface tension. Children will understand 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 addresses the salinity of water and the principles of buoyancy. Children will observe how salt affects the density of water and, consequently, the ability of the object to float.
Make Pepper Flee
A bit of pepper, water, and soap will create a captivating experiment. By adding soap to a container of water with pepper, children can observe how the pepper moves away from the soap. This is due to the surface tension of water, stimulating discussion about 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 will illustrate the concept of density and the role that salinity plays in the buoyancy of objects.
Create a Homemade Lava Lamp
With just oil, water, food coloring, and effervescent tablets, you can create a lava lamp. This fun project clearly shows how liquids of different densities interact and stack on top of one another.
Unpoppable Balloons
Use a simple technique to prove that, despite appearances, a balloon can be supported by a flame. By pricking a lit balloon with a sharp object, children will learn how pressure and temperature play a role in the resistance of materials.
