Science is one of the most important and interesting subjects. This subject makes students aware of various facts that happen around us. It gives complete foundations about the different topics before moving into the higher grades of education.

Science has helped us to find out different things that gave us what we have today. Without science, we all would still be living like an old caveman. In fact, without science, we would not have food, light, electricity, medicines, no vehicles for traveling, and lots more.

There are many interesting science experiments in the field of Biology, Chemistry, and Physics. We all find a lot of exciting experiments which require nothing more expensive than just a few types of equipment which are easily available. Here are few of them.

Simple Science Experiments for Kids

Experiment NO – 1 Floating eggs.

Materials Required.

For this experiment, we require 2 fresh eggs, 2 plain water glasses, regular tap water, salt and a tablespoon.


  1. Take two empty plain water glasses. Label them as 1 and 2.
  2. To the glass 1 completely fill with regular tap water.
  3. Now carefully drop an egg into it.
  4. You can observe that an egg sinks to the bottom of the glass.
  5. To the glass 2 fill with regular tap water, add 3 to 4 tablespoons of salt and stir it continuously till salt is completely dissolved.
  6. Now carefully drop an egg into it.
  7. Here you can observe that an egg floats at the top of the glass.

This experiment is mainly to prove that eggs are denser than regular tap water and the density of the water can be increased by dissolving the salt in the water. From this experiment, we can also learn that the salty water gives more lifting power. Therefore, it is easier to float in the ocean than a freshwater lake.


Experiment NO -2 Diffusion


Diffusion refers to the process in which the particles move from a region of higher concentration to the region of lower concentration.


Materials Required.


For this experiment, we require 2 beakers, warm water, cold water, and 2 to 3 spoons of food color.




  1. At first, take 3 glass beakers.
  2. Label the first beaker as a cold water, the second beaker as a warm water and the third beaker as a normal water.
  3. Now, according to the labelings fill the beakers with water.
  4. Add equal drops of food color into all three beakers and keep it aside undisturbed for a few minutes.
  5. After some time, we can observe that the diffusion has occurred faster in the hot water beaker. Therefore, from this experiment, we can learn that in hot water, the molecules vibrate faster than they were in the normal and cold water.
