Digital Rakhi (Indian Tradition)

Digital Rakhi Workshop

Component: LED, Black paper, White paper, Connecting wire, 3 Volt cell, Switch button, Steel plate, Decorating material, PCB.

Working: When we turn on the switch, 5 LED lights will turn on. These are turned on by a cell inside the bottle cap (on which they are on) and they will reflect on the steel frame, which creating a beautiful effect.

Introduction to Ultrasonic Technology And Applications At Nalanda Labs:

It is an acronym for Sound Navigation & Ranging (SONAR) Sonar is the technology of making use of sound waves to navigate, communicate and detect objects which are used for monitoring a particular area 24/7. It detects objects within 180 degrees and up to 8 meters. The word "sonar" comes from the first letters of "sound navigation ranging." Sonar can detect and locate objects under the sea by echoes, much as porpoises and other marine animals navigate using their natural sonar systems. In 1906, American naval architect Lewis Nixon invented the first sonar-like listening device to detect icebergs. During World War I (1914-18), a need to detect submarines increased interest in sonar. French physicist Paul Langévin constructed the first sonar set to detect submarines in 1915. At first, these sonar sets could only "listen" to returning signals. By 1918, Britain and the United States had built sonar sets that could send out, as well as receive, sound ...

Indian Space Research Organisation (ISRO)

Indian Space Research Organisation is the national space agency of India. Headquartered in Bangalore, established on 15 August 1969, under the chairman, Scientist Vikram Sarabhai. It performs tasks related to space based applications, space exploration and development of related technologies. In 1972, the Government of India set up the Department of Space (DOS). This department directly reports to Indian Prime Minister. ISRO works under the DOS. The Chairman of the ISRO is also the Secretary in the Department of Space. The Indian space programme was driven by the vision of Vikram Sarabhai, considered the father of the Indian space programme. ISRO Structure ISRO is managed by the Department of Space (DoS) of the Government of India. Secretariat of DOS and ISRO Headquarters are located at Antariksh Bhavan in Bangalore. Space scientist K. Sivan is the current chairman of ISRO. Important ISRO centres - Satish Dhawan Space...

Structured Capacity Building of Teachers

To equip teachers with the knowledge and skills required to impart the new curriculum to their peers and students, we are actively engaged in building the capacity of teachers through a series of training and continuous support. In terms of academic intervention, we are actively involved in designing content that aligns with the curriculum. Simultaneously, the model emphasizes teacher capacity building through virtual and in-person training sessions, covering both content and the pedagogy of teaching computer science. The primary objectives of these sessions were threefold: to instigate a paradigm shift in teachers' perspectives regarding the significance of digital literacy for students, introduce and provide training on block-based coding tools like Scratch Jr, and impart effective pedagogical strategies for teaching computer science in classrooms. The initial virtual training took the form of a summer coding camp, engaging 40 teachers during the summer break. This four-week- lon...
