Which part of the heart produces the heartbeat? Find out with this interactive task.
The heart’s main function is to pump blood throughout the body, as the primary organ of our circulatory system.
Ever wondered what makes this fist-sized organ work? What does it look like inside?
The heart has 4 chambers. The upper chambers are called the left and right atria, and the lower chambers are called the left and right ventricles. The left ventricle is the largest and strongest chamber in your heart.
There are two auricles, which are ear-like muscular pouches which arise from each atrium. They serve the purpose of increasing the blood-holding capacity of the atrium.
The aortic valve makes way for oxygen-carrying blood to pass from the left ventricle into the aorta – the largest artery.
The apex is the lowest part of the heart. It is the part that creates the apex beat – what we know and feel as a heartbeat that we feel when touching the chest.
Based on your reading of the text, can you drag and drop the parts of the heart into the right boxes?
Part #25: Meghnath is intrigued to learn about stealth technology that is designed to take on another technology…
While Nala and Hanuman experiment with air-powered vehicles on their way to meet Nila, Meghnath learns about stealth technology from Shakthi.
Shakthi: Meghnath, do you know about a technology called RADAR (Radio Detection And Ranging)?
Meghnath: No. What is it?
Shakthi: Radio waves are used to detect any kind of flying object in the sky.
Meghnath: How?
Shakthi: Just like light waves bounce off objects and reach our eyes, the transmitted radio waves reflect and reach a receiver that reads the object’s size.
Meghnath: Sounds like nothing can escape a RADAR’s eyes!
Shakthi: It can if you have the right technology.
Meghnath: A technology to counter a technology! That sounds interesting.
Shakthi: Yes. It’s called stealth technology.
Megnath: How is it possible for a large flying object to avoid being detected by these invisible radio waves?
Shakthi: Usually, these flying machines can escape from being spotted by human eyes by flying at a very high altitude. But, to escape the invisible radio waves, they use science. Now, tell me, how does a radar detect an object?
Meghnath: By sending across radio waves that will reflect off an object and return to it.
Shakthi: What if the object being detected does not allow the radio waves to reflect back to the receiver and instead deflects or diverts it into another direction?
Meghnath: That sounds like a good idea. How is it done?
Shakthi: Simple. By designing the vehicle like a diamond, the incoming radio waves will either be diverted or absorbed. Now that you have learnt what you came for, it is time to return to your consciousness. You can come back to me anytime.
Meghnath: Thank you, Goddess Shakthi. You are a great teacher
Shakthi smiles and slowly fades away and Meghnath snaps out of the photon world. Immediately, he sets to work building his own stealth vehicle.

Did you notice how the word radar reads the same when read forwards and backwards? Such words are called a palindrome. Here are a few more scientific terms or words used in science that are palindromes. Can you find them in the word grid?
