The Science Behind Transpiration: Do plants sweat?

Transpiration in plants

Transpiration in Plants

Transpiration is the loss of water from plants in the form of water vapour.

Imagine, during your summer vacations, you go to play football outside. The Sun is scorching hot. One thing you need right now, more than scoring a goal, is a bottle of water! Any living being for that matter needs the same. Do you think plants also need the same?

Yes, they do.

 

via GIPHY

In fact, the water does not magically disappear from a plant. Plants lose water from them through a process called transpiration. 

Transpiration happens in part because plants need to breathe. Plants need to take in carbon dioxide and to do this, they need to open their stomata. When this happens, water comes out

 

Transpiration is the process by which moisture is carried through plants from the roots to small pores on the underside of leaves, where it evapourates to vapour and is released to the atmosphere.

Transpiration Water Cycle

This release of water vapour into the atmosphere, through transpiration, creates a water cycle. It is called the transpiration water cycle. It occurs when:

 

  • The water from the nearby soil is absorbed into the roots due to the hydraulic conductivity of the soil and the magnitude of the pressure gradient through the soil.
  • The water flows from the roots to the leaves. This is driven by capillary action (Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules).
  • The water from the leaves enters the atmosphere. The water potential in the surrounding air is lower than the water potential in the leaf airspace of the stomatal pore. Due to this, water vapour from the cells in the leaves enters the atmosphere as water vapuor. This process is known as transpiration.
  • The water vapour in the atmosphere now forms clouds through the process of condensation. 
  • And these clouds of water vapour turn into water droplets and fall back on earth through the process of precipitation
  • This water that falls on the land, is then absorbed by the soil and is used to nourish the plants. 

This cycle keeps repeating and hence, is called the transpiration water cycle.

Tactivity

You will hardly need anything for this tactivity. If you have a broad leaved plant in your garden, then it is well and good, otherwise you can always head to the nearest park and look for the same.

All you need to do is wrap a plastic sheet around the leaf and close it tightly. Wait for a few hours and you will see water droplets inside the plastic sheet, as though the leaf has “sweat” – or  TRANSPIRED – as  shown in the video below:

We All Have a Puppeteer

Before I disclose who your puppeteer is, I want you to play a game.

No, it’s not you. 😉

You have to stare into your friend’s eyes and whoever blinks first will lose.

With this, one thing is clear,you are not the puppeteer of your own body because you have to try so hard to not blink, despite being the master of your voluntary movements!

Who is the master?

It’s your brain!!

Yes, you have to be grateful to your brain for making you remember where your best friend lives or the dreams that you have when you are asleep, or not being in charge of how often you blink.

via GIPHY

Isn’t it amazing that your brain knows when you are asleep and doesn’t disturb you by making you constantly blink your eyes; or know when you are awake, hence not bothering you to start dreaming?

To sum it up, intelligence, creativity, emotion, and memory are a few of the many things governed by the brain.

Of course, the main factor to be thankful for is that we are alive because of it.

Strings Attached

Now we are going to make a brain model of our own.

The model will make it fun for you to understand the main parts-or-strings- that make us puppets, think innovative things and function in our day to day lives.

Protected within the skull,the brain is composed of the cerebrum,cerebellum, and brainstem.

The brain receives information through our five senses: sight, smell, touch, taste, and hearing. 

Fun Fact: The adult brain weighs 1.5 kilograms(3.3 lbs), on average.

  1. Cerebrum: largest part of the brain. It allows you to move, touch, feel and see.
  2. Cerebellum: coordinates you to maintain postures, muscle movements and balance. It is behind all the amazing yogis and gymnasts that represent our country.
  3. Brainstem: includes the midbrain, pons, and medulla. It acts as a relay centre connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing,coughing, vomiting, and swallowing.
  4. The 4 Lobes of the brain: frontal,temporal,parietal and occipital. Each lobe may be divided,once again, into areas that serve very specific functions.

i) Frontal Lobe

  • Personality,behaviour, emotions
  • Judgement, problem solving
  • Speech
  • Body movement
  • Intelligence, concentration, self-awareness

ii) Temporal Lobe

  • Memory
  • Hearing
  • Understanding language

iii) Parietal Lobe

  • Interprets words
  • languages
  • sense of touch
  • pain
  • Interprets signals from vision
  • hearing, sensory and memory

iv) Occipital Lobe

  • Interprets vision (colour, light, movement)

The brain is an organ that serves as the centre of the nervous system and is the most complex organ in the human body.  The brain is located in the head, close to the sensory organs, such as the eyes.

Now that we are coming towards the end, you may feel happy to realise that the process of understanding this blog was an example of yet another successful puppet show!

1 Tool Away from Improving Your Cognitive Skills

Wonder why some of your friends are faster at grasping concepts in class? 

via GIPHY

Earlier we shared 5 ways to improve your critical thinking.

Likewise, we will share the secret of being the fastest learner in class.

Time to put your ThinkTacap  on.

via GIPHY

Now you must have figured that cognition is merely a reference to memory-ability to comprehend new information, speech and written notes. 

What builds your cognitive skills?

We are constantly in touch with our surroundings,physically and mentally. 

When you are sitting in class distracted, it’s because the learning experience is not able to grab your attention, instead wanting to figure out what the other student outside your classroom is doing seems more fun. 

You may notice that I highlighted learning experience;simply to help you understand why being distracted seemed like a better idea.

For instance, the other kid standing outside your class filling his water bottle and then ending up spilling it all over him by mistake, made you laugh. 

via GIPHY

He grabbed your attention by the activity he was performing. You may have observed how the water was filling up the bottle and the process of mishandling the object (water bottle). 

Now you are willing to share that with your friend,right? You tell your friend in detail what happened and how silly or embarrassing it must have been for that kid. 

Fun Fact: If you recall such an incident, you do have a great cognitive memory. 

Learning The Important 

Wouldn’t your class been more fun if you had an experiential tool to  practically show you what magnetic forces do? 

They can definitely make a frog jump. Yes, try it for yourself and be the whiz kid of class that you are.

Don’t forget to share the cool trick with your friends and teacher too. After all, interacting with people and remembering their face is part of improving your cognitive skills. 


Therefore,  choosing any one experiential tool that can help you understand a concept will not only improve your cognitive skills but also enhance your knowledge and passion for Science.

The One True Way To Make Learning Fun For Your Child

Fun? What’s that?

After a  long day at work, you come back home exhausted and you just want to sleep. But then you remember that your little one has his homework to do.

With the diminishing energy that you have, you sit with him to do his homework, only to see him apathetic and unresponsive to your attempts at making him study!

Well, if this is the case, then I can assure you, you’re not alone.

The Plague

Education in India is continually found guilty of being mundane and pro-rote methods. We can definitely empathise with our kids on this one, as we ourselves have been victims of this education system. 

Children Studies
Make learning fun for children

The one thing our kids focus on while they sit there “ardently” studying is, when they can go back to play

We have always categorised School and games as mutually exclusive. But, can there be a fun way to integrate the two and give our children the fun they seek, whilst giving them the knowledge that they require? 

The Trick

Yes, the very scarce, yet obvious solution to this would be to integrate the polar opposites of fun and education.

According to a report by Jessica Sanders in her Market Analysis blog, 70% of teachers have seen that implementing games in their teaching aids increases the response they get from students, yet only 18% of them are implementing them.

This is the reason why ThinkTac has come up with a range of fun and games to redefine how schools teach in India.

studying for kids

Benefits of the Integration

I can assure you that the benefits to this integration are endless but here are my top few:

  1. Deep-rooted understanding: When youngsters play a game, they tend to go through the instructions and technicalities more carefully. As they are aware that these need to be recalled at a point later in the game. The perks of knowing the terms and complex jargon are more exciting in a game vs. a mundane Monday morning lesson.
  2. Dealing with Failure:  Games transform the discomfort and mental hurdle that ‘failure’ can create and turns it into an opportunity to master the task at hand.
  3. Increasing the attention span: With the advent of smartphones, the attention span of the younger generation has been on a big decline. With the focus needed in video games, your kid can now have a platform to work on the dearth of his concentration. 
  4. Less to worry: Going back to the point of you coming back exhausted from work, you can now be rest assured that your child is studying wisely and you can finally sleep peacefully!

At this note, I shall leave you with some food for thought. 

When we make play the foundation of learning, we teach the Whole Child.

TACtivity To Understand Simplicity 

Nowadays, the biggest hurdle to overcome is the kid’s attitude towards Science. 

You might think that it is boring or you simply don’t understand it. 

However, you may realise that declaring Science to be tough is simpler than trying to understand why!

Textbooks earlier said, ‘Man needs air, water, food and shelter for survival.’ Today they might as well say, ‘Man needs air, water, food, shelter and machines for survival.’

We, at ThinkTac,understand this and realise that classrooms need to bring the hands-on experiential tools approach to help you understand better and not fear it.

After all, we like what we understand.

Let’s Understand 

Okay, Junior Einsteins ! To invent, you need imagination and a pile
of junk. 

Yes, that’s how simple it is. 

TACtivity 1

We all are aware of the DIY experiments that we go through every now and then, especially when we have a science project submission to do.  

via GIPHY

However, we are going to move beyond the “memorising without understanding” approach.Y

Don’t run after the A grade, make it run after you. 

If you are in love with music and want to be reminded of your limits every time you play your favourite jam out loud,then making a SPEAKER is what you are going to love. 

TACtivity 2

Yes, we have more!! 

You know how people pull water from tube wells? There was a genius like you behind making it convenient for the people. 

You know what it’s called ? Yes, it’s called a pulley and you can make it on your own now. Also, understand better the process integrated in executing a pulley. 

All you need to do is to be a witness to your surroundings and practise the 3Rs at the same time- Reduce, Reuse, Recycle. 

Do you have innovative ideas of your own? 

Don’t shy away from contributing to the growth of Science.

The Secret to Unleash Your Inner Science Maestro!

Can You Master Science Like Never Before?

“Curvilinear motion is defined as a motion that occurs when a particle travels along a curved path, which can be in two dimensions (in a plane), or in three dimensions. This type of motion is more complex than rectilinear (straight-line) motion”

Clueless? Me too.

Is science giving you a hard time? Well, what if I told you that you could fall in love with this incomprehensible subject?

Back in fourth grade, remember when we were learning about how sound waves are transmitted and we made that device with two cups and a string?

Not only did that make me feel like Graham Bell; but that experiment, it stuck with me. In fact every time I backed up a theory with a practical experiment it really got ingrained in my system.

But then, what did I do differently?


The Big Revelation

via GIPHY

Presenting to you, experiential learning. The practice of learning something by actively doing it and then reflecting upon it. The reason experiential learning is so implementable in scientific study is that it imparts qualities onto its learners.

Qualities like logical thinking, critical reasoning and making keen observations. It helps students unlearn and reorder the conception of any topic, leaving no room for dull, lifeless and rote learning approaches.

Hands-on examples, further benefit traditional science learning as they provide an industry relatable experience.

Once the learning outcomes of any topic are established, they can be implemented through various experiential disciplines. 

Take it Home

Remember the first paragraph on Curvilinear Motion that needed Alan-Turing-like deciphering skills? Well, it can be broken down into the simplest way – using household items like binding wire and springs through experiential learning. 

This video by ThinkTac shows you how:

So, are you ready to get your hands dirty and redefine the phrase “rocket science”?

Are We Losing The Elon Musk In Us?

Let your child be the superhero he admires.

Science for Kids

Youngsters are brought into the world with a characteristic inclination to learn.

From that point on, they set out on the adventure of revelation dallying with their environment, forming circumstances to their benefit and making the most inventive inquiries.

Science is a programme already embedded in our mind.

Wonder HOW?

These youthful personalities are inventive and their paper watercraft, sand palaces, conceptual illustrations and sketchy recreations are outlets of the imaginative limits in them.

It is through this experiential cooperation with the world that they start to innovate. Science, thus, originates from this; it is intrinsic, alive and continually developing. 

“Science is not only a discipline of reason but also one of romance and passion.”

-Steven Hawking

As children grow up, they forget the superpowers that they possess – if one can dream it, one can make it. 

Maybe that’s why India is stagnant. I know I have given you a lot of Hows to ponder upon but if not now, then when?

India was incidentally one of the very first countries to catch up with the post-Industrial-revolution era.

The same nation today, is in the fight to become a scientific superpower.

Is the competition real? 

The Indian Intelligentsia believes that the citizens of this nation are caught in a vicious cycle of mediocrity, and this is a cliché. 

Additionally, increasingly slender career pyramids are forcing students to engage in a rat race to be the cherry atop a terrible cake. 

Hence, it is tough to opt to be a Scientist when we are past adolescence as our minds have now been conditioned to believe that Science is about endless digits and out-of-the-box research work 24/7. 

You ask WHY?

Education is aligning to a ‘one size fits all’ approach that is depriving students of exploring the concepts at a real-time avenue, Hence, resulting in a tumbledown passion for science. 

Thus, making your child forget how to use his/her superpowers. 

Solution 

  1. The solutions are infinite at ThinkTac. You can get your little munchkin started with his/her very own experiential tools to start building up the superhero suit.

After all, Spider-Man, Superman, Superwoman and Batman have one.  

  1. You can also enrol them in an always-fun course because we are not limited to using blackboards. We encourage discussions and welcome innovations. 

The study of science and maths are originally like games with rules but no objectives and that is essentially how they must be revised.

If you think your superhero already has it in him/her to save the world with his/her innovative ideas and win rewards, then you can sign up for the last biggest event of 2018. 

Let the New Year be a new milestone for your child!
