Students Amazed by Weight Variations on Different Planets at Delhi Science Festival
In a fascinating demonstration of planetary physics, young participants at the Vigyan Utsav in New Delhi were surprised to discover that their body weight changes dramatically across the solar system. The event, organized by the Prime Minister’s Museum and Library (PMML) to mark National Science Day, featured an interactive pavilion titled "Know your weight on different planets."
Rachna's Astronomical Weight Discovery
Fifteen-year-old Rachna, with an actual weight of 46 kg on Earth, was shocked to find herself "standing" virtually on Neptune, where her weight increased significantly. When she recalculated on Venus, she was thrilled to weigh less than her Earth weight. This hands-on experience highlighted how surface gravity varies due to planetary mass.
Posters at the pavilion explained the science: weight on Neptune is 1.19 times that on Earth, while on Venus it is 0.91 times. This means a person weighs more on Neptune because of its stronger gravity, a direct result of its higher mass compared to Venus.
Interactive Learning and Scientific Engagement
The day-long festival, themed 'A Carnival of Curiosity,' was hosted by the Nehru Planetarium and PMML to foster scientific inquiry through entertainment. Beyond the planet pavilion, activities included:
- Free virtual reality shows offering immersive space experiences
- 'Nukkad Nataks' (street plays) promoting science awareness
- Hands-on physics games and DIY STEM kits from Vigyan Vyanjan and KMC Astroclub
- Displays of science books, telescopes, and innovations from various creators
Hand-made paintings of physicist Dr. C.V. Raman and scientist Dr. A.P.J. Abdul Kalam were exhibited to inspire young enthusiasts.
Promoting Scientific Temper in the AI Age
PMML director Ashwani Lohani emphasized the event's importance, stating, "Such events showcase the deep roots of democracy in the country besides promoting scientific temper in this age of artificial intelligence." He highlighted how interactive learning can combat misinformation and encourage critical thinking among youth.
The festival also celebrated the 130th birth anniversary of former Prime Minister Morarji Desai, with a panel exhibition detailing his life and contributions. This blend of historical reflection and futuristic science aimed to create a holistic educational experience.
By engaging children in practical experiments and cosmic calculations, the Vigyan Utsav successfully demonstrated fundamental astronomy concepts, making science accessible and exciting for the next generation of innovators.
