Budding Scientists Club (2019-2020)

Floating and Sinking Orange - 30.01.20


In the activity conducted on 30.01.20 the students explored the concept of density through a fun-filled science experiment. They observed  that an orange with the peel  floats in water because of its porous peel filled with tiny air pockets On the other hand, when the peel of the orange is removed, the same orange sinks in water as it becomes lighter due to lack of tiny air pockets. The students were able to infer that the orange without the peel is denser than water which makes it sink.

Experiment -There’s air in there!


The experiment- ‘There‘s air in there' was conducted for the students on 28.11.19 under the aegis of Budding Scientist Club.  The teacher catered to children’s natural instinct of asking questions and tried to bring out a  budding scientist in them.

Through a simple experiment they explored the property of air pressure and observed how putting an inflated balloon over the top of the bottle pushes the water  out of the bottle through a straw inserted in it. The teacher demonstrated and explained the experiment to the students.  The students then tried doing the experiment under the teacher’s guidance. A video related to the experiment was also shown to reinforce the concept.

Experiment- Making of Water Lens


Through a simple experiment conducted on 24.10.19, the students learnt to make a lens with a glass of water and observed the concept of refraction.
A paper with a horizontal arrow drawn on it was put behind a glass. The distance between the glass and the arrow card was adjusted to see the image clearly through the empty glass. Then it was slowly filled with water and when the arrow was seen through the filled glass, the image of the arrow appeared reversed.
The club master conducted the experiment and explained how the water in the glass behaved as a convex lens to make this happen. She further explained that the curvature of the convex lens bends light in such a way that the image of the object appears inverted.

Colour Changing Milk

Club activity ‘Colour Changing Milk ‘ was organised for the students on 26.9.19. A demonstration showing the reaction of milk with liquid soap was given to the students. To highlight the movement of milk molecules different food colours were added to the solution. Students keenly observed and inferred that as soon as soap was added to milk,  food colour present in milk appeared to be dancing and moving on its own.

This is due the reaction of the soap with the fats particles  present in milk..  Then students were amused to see the colours mixing and changing on its own and thoroughly enjoyed the activity.

Experiment- Making of Gas


In the activity conducted on 29.8.19 the students learnt how a chemical reaction between baking soda and vinegar leads to production of a gas. In the simple experiment demonstrated by the club masters, the two ingredients were mixed to produce carbon-dioxide which was used to inflate a balloon.

The fun-filled experiment was a great learning experience for all the students.

Balloon Rocket Experiment 

To enhance analytical thinking and give a hands-on experience to our young budding scientists, the  Balloon Rocket Experiment was conducted under the aegis of Budding Scientists Club on 25.7.19. In this activity, the students enthusiastically turned their balloon into a rocket and launched  it on a string tied across the classroom. The air trapped inside the balloon pushed out the open end, causing the balloon to move forward. The principle behind this movement- Every Action has an Equal and Opposite Reaction’ was explained to the students. The students participated whole heartedly and enjoyed  the activity under the guidance of the club incharge.

Experiment- Making Invisible Ink

Through a fun-filled magical experiment conducted on 25.04.19, the students learnt how to make invisible ink using lemon juice and a heat source. They drew a picture on a white paper using the lemon juice ink and ear bud. They were thrilled to reveal the picture by placing the paper at the right distance from a candle under the supervision of teacher. The oxidation property of lemon juice was explained through this experiment and the students learnt that lemon juice is an organic substance that oxidizes and turns brown when heated.
