In India, National Science Day is observed on February 28 each year to honor Indian scientist Sir Chandrasekhara Venkata Raman, who discovered the Raman Effect in 1928. The purpose of the day is to raise public awareness of the value of science and its contributions to society. An important event that aids in encouraging a scientific mindset among kids is National Science Day celebrations in schools. In this post, we’ll explore National Science Day project ideas and the value of encouraging students to learn about science.
National Science Day Project Ideas
The best way to ensure that your kids have a good understanding of science is to encourage them to participate in easy science projects for school-age kids that they can try at home using supplies you already have. Here are some National Science Day project ideas from a variety of scientific disciplines, including physics, chemistry, and biology.
- Investigating the properties of light
Set up an experiment to study the properties of light, such as reflection, refraction, polarization, and diffraction. You can use prisms, lenses, mirrors, and other optical devices to create different light patterns and observe their behavior.
- Crush a can using air pressure
In order to crush a can with air pressure, a little amount of water must first be heated in an aluminum can, then the can must be sealed with a lid and quickly cooled. The air inside the can is forced out as a result of the pressure created as the water inside the can heats up and turns to steam. The can get crushed when the steam condenses back into liquid after being quickly cooled because it takes up less space when it does so. This experiment illustrates the characteristics of pressure and the behavior of gases in a fun and informative way. Before attempting this experiment, it’s crucial to be cautious and follow the necessary safety measures.
- Learn how salt affects the density
Salt can affect the density of a liquid in a few different ways.
When salt is added to water, it increases the water’s density by adding mass without significantly increasing the volume. The salt ions also increase the attraction between water molecules, making it more difficult for them to move apart and reducing the amount of space between them. This results in a more tightly packed liquid, which has a higher density. However, adding salt to a liquid can also change its density in other ways. For example, if salt is added to a solution of water and ethanol, the ethanol molecules will be pushed away from the salt ions and will cluster together, reducing the overall density of the solution.
The effect of salt on density can also depend on the temperature and pressure of the liquid, as well as the type and amount of salt added. By experimenting with different concentrations of salt and different types of liquids, you can learn more about how salt affects density and how this can be applied in various scientific and practical applications.
- Purify water with charcoal
Charcoal can be used to purify water by adsorbing impurities and contaminants from the water. The porous surface of activated charcoal has a negative charge that attracts positively charged impurities such as toxins, heavy metals, and chlorine. The impurities bond with the charcoal and are effectively removed from the water.

- Conducting a chemical reaction
Perform a chemical reaction, such as the reaction between baking soda and vinegar, and observe the changes that occur. You can also study the properties of different chemicals and learn about their uses in everyday life.
- Explore how sugary drinks affect teeth
Eggshells are an excellent substitute for teeth due to their calcium content. Students investigate how soda and juice discolor teeth and wear down the enamel using eggs in this experiment. (As an added bonus, encourage students to test out various toothpaste and toothbrush combinations to determine their efficacy.
Remember, the key to a successful science project is to choose a topic that you are interested in and to approach it with an open mind and a willingness to learn.
