Studies can be Interesting When You Implement the Knowledge in Life

Studies are the most influential and exciting when you apply the learned knowledge through amazing science experiments with everyday materials. Children are the most expressive and enthusiastic ones. They look forward to doing science activities. It is always worth doing something where they get to know the unknown and see the unseen.

We celebrate National Science Day on the 28th of February every year. On this day in 1987, scientist CV Raman Invented the Raman Effect. The day is celebrated to commemorate his discovery. Raman was honoured with the Nobel Prize for his contribution to the field of science. Simple science experiments for kids will be super fun for the growing-up student. Below are a few such science craft ideas.

Make Butter in Jar

Students learn about dairy products in school. Make them know how dairy products are transformed from one form to another. Making butter will be a fun science experiment.

  • Take a mason jar, thickened cream, and 2 marbles. 

  • Pour some thickened cream into the jar.

  • Make sure there is enough air.

  • Keep it out of the fridge until that gets to average room temperature.

  • Put 2 marbles in the jar. Marbles agitate the cream further.

  • Keep shaking the jar as long as it is needed.

  • Finally, open the jar and separate the butter from the buttermilk.

Tell your students to notice the different stages the cream goes through to turn into butter. The scientific reason behind the process is that when you shake the fresh cream, the fat molecules of the cream shake out of position and start to clump together. After a while, fat molecules keep clumping together until you make a butter lump. The left liquid is called buttermilk.

Yeast Experiment

Yeast Experiment

Yeast Experiment

Start this science experiment at home early in the morning. You might need long hours for the task. Students read about yeast and its part in making bread. Show them what yeast looks like exactly. Add some warm water to it, and watch out for what happens. Discuss with your students what all living things depend on growing?

Well, the answer is water and food (besides oxygen). This experiment is about what happens when the yeast is given food. The food is sugar here. Mixing with water and sugar makes the yeast burp and release carbon dioxide. Explore what if you change the amount of food.

Material Required

  • 4 plastic bottles

  • 4 balloons

  • 4 packets of yeast

  • Warm water

  • Granulated sugar

  • Funnel

  • Teaspoon

  • Measuring cup


  • Pour a cup of warm water into every bottle.

  • Add a packet of yeast into every bottle.

  • Add teaspoons of sugar into each bottle in the sequence- 0, 1, 2, 3 teaspoons, respectively.

  • Put the lid on each of the bottles and shake well.

  • Now take the caps off and put a balloon on top of every bottle.

  • Keep them aside the whole day.

Get your yeast ready exclusively at home. Yeast is majorly used in making bread items, burgers, sandwiches, etc. In a natural process, yeast can be made by combining and fermenting yeast (that comes in packets) with water and flour. Then you keep the mixture for hours. Thus the yeast thrives and grows. 

Static Electricity Experiment with Comb

Many things can act like magnets. All they need is just an electric charge. For example, let's check if you give an electric comb charge. Can it snatch pepper from salt! Here is one experiment which can tell you exactly how.

Material Required

  • A plastic comb

  • Salt

  • Pepper

  • Tissue

  • Pen

  • Notebook


  • Lay a tissue flat.

  • Pour some salt into it.

  • Pour an equal amount of pepper into the tissue again.

  • Mix the salt and pepper in an even consistency.

  • Give the comb an electricity charge by rubbing it through the hair a few times.

  • Hold the comb one inch above the salt and pepper.

  • Move the comb over the mixture.

As a result of the experiment, the pepper particles get attached to the comb. And, the salt remains in the tissue. It happens because salt is denser than pepper. As a result, pepper has more surface area that can get charged by the comb's static electricity. That allows the pepper to be attached to the comb. 

Plant Seed

Plant Seed

Plant Seeds

The 3rd one is one of the easy science experiments to do at home. Students will learn how vegetables can regrow from seed. Thus they will be inspired to eat healthily. Replanting vegetable seeds is a great way to teach young students about food value. 

Material Required

  • Small glass jar

  • Bean/Pea seeds (or both)

  • Soil

Beans or peas germinate more quickly than other seeds. This is because these seeds are more extensive. So they are better for experiments. 


  • Put the soil at the bottom of the jar.

  • Put a few seeds in the jar.

  • Place them next to the glass for a better view.

  • Add much water to dampen the soil.

  • Put the jar beside a window from where it gets sunlight.

  • Within a few days, the seeds will start to germinate and grow.

  • Observe the weekly changes and growth.

  • Take care of it till flowers come out of the plant, and then you can place them in the balcony garden.


You can consider the options above whenever you are free and looking for an interesting activity. These activities are fun and can help you learn about new things. Do the above experiments at home and get surprised with amazing results. The above scientific experiments are cost-effective, easy, and worth trying. On National Science Day try these kindergarten DIY activities. Share your experience. Share the blog with your science enthusiast friends too. You can arrange the experiments altogether.
