Quarantine School - Resource Pack #1

#self-learning #tips #quarantine-school

Your learners are at home all day. Good time to learn about LED lightbulbs, transistor radios and WhatsApp forest fires!


Quarantine School – Resource Packs
Engaging, exciting, thought-provoking learning triggers!
Beginning Wednesday, 1st April, 2020

The learners are bored, the teachers are unavailable, and the parents are tired.

Chachi is here to help!

Today we kickstart the Quarantine School series with three learning triggers in every resource pack. These should ideally be used by parents or teachers as conversation starters with learners. Based on the learner’s interest or your intended learning objective, you can pick whichever trigger you like and facilitate a journey of exploration!

  1. How do LED lights make a rainbow?
  2. “Nana, what is Akashvani?” - The Story of Transistor Radios
  3. How quickly will the WhatsApp forest burn?

How do LED lights make a rainbow? #

LED lights have practically replaced almost all lighting fixtures in our homes in the last few years. You have probably seen advertisements on the TV as well. (“Syska LED - Light Years Ahead!”)

  1. Do you know what type of lightbulbs we had before LED? Have you heard of CFL lightbulbs? How about incandescent bulbs? Try to find out what all types of bulbs used to be available 10 years ago. See if you can find out what a zero-watt bulb is!
  2. Have you heard that the LED bulb is cheaper to operate than any other bulb? Why do you think that is the case? Try to find out how LED bulbs consume less electricity than other types of bulbs.
  3. We know that a blue bulb gives blue light and red bulb gives red light. But have you seen that the same LED bulb can give off light of multiple colours? How is that even possible? Try to find out how an LED bulb is able to change its colours.

In your search you might come across terms like resistors, diodes and junctions. These are components of an electrical circuit. See if you can find an online game that lets you play with electrical circuits. If you can take the help of an adult you can even make your own circuit with the help of a watch cell!

“Nana, what is Akashvani?” - The Story of Transistor Radios #

You’ve probably heard of Doordarshan - India’s national television broadcasting service. But do you know what Akashvani is? It’s a fun topic to talk to your grandparents about! You’ll get to learn about transistor radios which was basically the grandfather of the iPhone!

  1. If you have a FM radio at home (ask an adult!), tune into 107.2 FM and listen for at least 5 minutes. This doesn’t sound like Radio Mirchi or BIG FM at all! Try to find out why this radio station is so different from other stations.
  2. Ask your grandparents about their earliest memory of a radio. Try to find out how the radio changed their lives.
    1. When did they first buy a radio themselves?
    2. What was the size of the radio? Could they carry it in their pocket with them? Could they use headphones with it?
    3. Which programmes did they tune into on the radio? What type of content did these programmes have?
    4. Did they ever schedule their day’s plans around a special radio programme?
  3. You will probably hear the words “transistor radio” and “radio” used interchangeably in this conversation. Try to find out if there is a difference between a transistor radio and an ordinary radio. Ask your grandparents or search on the Internet!

How quickly will the WhatsApp forest burn? #

You probably know how forest fires happen. One tree or bush dries up and catches fire due to the heat. The foliage around it catches fire from it and the one around them catch fire from them, and eventually the whole forest starts burning.

  1. If one person forwards a WhatsApp message to two people. And those two people forward the same message to two other people each.
    1. How many people have received the message so far?
    2. Okay, now can you find out how quickly the message will reach 100 people?
    3. How about 5000 people? See if you can figure out a formula to quickly calculate the result for any number of people.
  2. Do you think the current coronavirus pandemic shows a similar behaviour as this forest fire? If you’re interested in learning more, watch this video that explains the spread of an epidemic with the help of a great simulation.
