E12 खगोलीय घटना व निरीक्षणे

About the Talk: पावसाळा संपत आलाय (बाहेर बघून तसं वाटत नाहीयं, पण तरी..)! आकाश निरीक्षक आता शरद ऋतुतल्या चंदेरी रात्रींची आतुरतेनं वाट बघतायत. तुम्हालाही आकाशातले ग्रह, तारे आणि त्यांचे विलोभनीय खेळ बघायला आवडतात ना? या वर्षीच्या उरलेल्या तीन महिन्यांत आकाशात घडणाऱ्या खास घटनांची यादी तर लांबलचक आहे. ग्रहणं, गुरूचं खास दर्शन, उल्कावर्षाव, आणि बरंच काही! तर आपल्या येत्या STEAM Boat मध्ये आपण ह्या आगामी घटना आणि त्यांना कसं आणि कुठून बघता येईल याचा आढावा घेऊया.

The end of the monsoon marks the beginning of clear night skies. It is a time when astronomers and sky gazers gear up for the clear star-studded winter nights and all the exciting phenomena that comes with it! And who doesn’t love to see the stars, planets and eclipses? Over the next 3 months, we have some spectacular astronomical events like the eclipse of the sun and the moon, meteor shower and there are also planets to look forward to. We will discuss these and also some tips on how to go about our observations and prepare for them. Let’s meet in the upcoming STEAMboat session to talk about all the mesmerising celestial events that are lined up before the new year begins. Happy Sky Watching!

The live session will be in Marathi.

E11 आइए क्षेत्रफल ‘गिने’!

About the Talk: Let’s ‘count’ areas!

Have you seen ‘dot grids’? They are widely used to make rangoli designs. You might have learned to ‘calculate’ or ‘measure’ areas of certain simple geometrical shapes like squares and triangles. Do you know that we can use these dot grids to find areas of complex and asymmetric shapes? Not just that, we will also explore how can we find the area of any shape by simply counting dots! So join us for this exciting STEAMboat session!

आइए क्षेत्रफल ‘गिने’! क्या आपने कभी ‘डॉट ग्रिड’ देखे हैं? ये वही है जिनका उपयोग रंगोली डिजाइन बनाने में किया जाता है। आपने सरल आकारों, जैसे की वर्ग और त्रिकोण, का क्षेत्रफल ‘मापन करके’ या ‘सूत्र के प्रयोग से’ निकलना सीखा होगा।क्या आप जानते हैं कि इन डॉट ग्रिड का उपयोग करके हम किसी भी जटिल और असममित आकारों के क्षेत्रफल भी ढूंढ सकते हैं? इतना ही नहीं, हम यह भी पता लगाएंगे कि कैसे हम केवल बिंदुओं की गिनती करके किसी भी आकार का क्षेत्रफल ज्ञात कर सकते हैं! तो इस रोमांचक STEAMboat सत्र के लिए हमसे जुड़ें!

The live session will be in Hindi.

E9 बारिश की बूँदें

About the Talk: Our next #STEAMboat session will have Disha share with us the shape of raindrops.

Monsoons bring a smile to all, the young and the old. It is fun to play in the rains and the pitter-patter is a music we all love listening to. Have you ever taken a moment to look closely at the raindrops? What happens to them when they fall from the sky to the ground? Have you ever thought about what is the shape of a raindrop? In this session, we will explore the shapes of raindrops and the reasons for it! Join us for the upcoming STEAMboat session on 10th July at 11AM.

बारिश …… वो ऋतू जो बच्चो से लेकर बूढ़ों के चेहरे पर मुस्कान लाती है। बारिश के मौसम में पूरी तरह भीग कर उसकी बूंदों के साथ खेलना सबको पसंद है। पर क्या आपने कभी इन्ही बूंदो को गौर से देखा है ? कैसा होता होगा उनका सफर आसमान से ज़मीन तक ? कैसे वो बादलों में से गिरकर छत पे से टपकते हुए, फूलों पत्तों को छूकर, ज़मीन में मिल जाते हैं। तो अगले स्टीमबोट सेशन में हम इन्ही सारी दिलचस्प बातों पर चर्चा करेंगे।

E8 Flying buses, superhuman strength, invisible people: Where’s the Physics?

About the Talk: We all watch and enjoy movies. People achieve far-fetched feats and cars jump from one place to another in an unrealistic fashion; and let us be honest- we all enjoy it and may also believe a part of it to be true! Some of these movie scenes cross the valid boundaries of science and show us many unbelievable events. In this session, we will try to break down some movie scenes, do some quick calculations and check whether they follow the rules of physics. So let’s together explore the world of movies and science, in this #STEAMboat session!

The live session will be in English and Marathi. Versions in other languages will also be made available later on HBCSE YouTube channel in the following weeks. The links will be available on this website.

E7 Seeing sounds!

About the Talk: Throughout our day, we are exposed to a wide variety of sounds. Even when we communicate with others, we majorly rely on sound waves to do so. Usually, we just ‘hear’ these sounds. But is it possible to ‘see’ them as well? Let us find out in the upcoming session of #STEAMboat! We will also try to understand how one can identify different sounds, by using some special properties of sound. And lastly, we will also have a look at some interesting phenomena related to sound!

E5 Rango ka khel!

About the Talk: As we prepare for Holi, the festival of colour, let’s ask ourselves what is colour after all? We live in a world bathed in light, and at least most of us can see the various colours of objects that make our world so beautiful. But what is colour anyway? Is there pink in a rainbow? Why do two people see the same colour differently? Well, colour is all in our head! While light has intrinsic physical properties such as wavelength and intensity, colour is not actually a property of light or of objects that reflect light but entirely a sensation that arises in our brain, due to a complex chain of events starting from when light enters the eye. And the brain can even be fooled to see colours that don’t exist! Join us in our Holi special as we dive into the world of colour!

E4 Let’s Measure! Oh, is that so Simple?

About the Talk: Measurements are an integral part of everyone’s life. We have become so accustomed to the idea of measuring and quantification that nowadays, our happiness and anxiety also get a number! Practices of measurement come from historical agreements, where we compare an unknown quantity with a known or standard one when we measure. This talk will illustrate the historical development of basic measurements such as length and area in the world and Indian context. Then we will unpack a chapter of history on measuring the volume of a sphere to understand the role of accuracy in measurement. Lastly, we will see how the development of standardised units is represented in school mathematics and examine some students’ practices wherein their after-school jobs required them to constantly make negotiations to achieve accuracy.

The live session will be in Marathi. Versions in other languages will also be made available later on HBCSE YouTube channel in the following weeks. The links will be available on this website.

E2 Here comes the Sun!

About the Talk: We all know that the sun rises in the east and sets in the west … but when was the last time you actually watched sunrise or sunset? What if we told you that it didn’t rise at the east or set at the west today?! This sounds a bit unbelievable, so we encourage you to go out and check for yourself! Then, join us for the next session of STEAMboat, where we look at where the sun actually rises and sets. And we try to understand why this happens by imagining how the sun moves through the sky. Along the way, we see that how the sun moves in the sky depends on where you are on the earth, and on what time of the year it is.

E1 The Superb Spider’s Super Silk

About the Talk: Encountering a cobweb on one’s face or hands during a stroll can be quite unpleasant. Still, who isn’t impressed by the agility and athletic skills of the superhero ‘Spiderman’. Who says entertainment and science are an unlikely couple? Let’s explore the story of the sci-fiction movie ‘The Amazing Spiderman’ and try to connect it with the research on understanding spider silk - an amazing fibre produced by an equally amazing creature. We’ll look at how spiders, who’ve been around for almost 380 million years, spin this wonder material, and look at some of its unique properties. And we’ll check if Spiderman’s artificial silk-producing gadget is a possible reality of science or mere fiction!
