Explore Science 

If kids have a favourite question, it's probably 'Why?''

At Team Explore we try and make science fun and exciting for your kids by encouraging their natural curiosity about the world and teaching them how to find answers for themselves. After all, much of science is investigating “Why” and “How”.

Like scientists, kids can sharpen their observation skills and learn to make and test hypotheses to find the answers. Introduce your kids to inquiry-based learning. This mainly involves letting children ask questions, and then responding in a way that allows them to use observations and draw inferences to come to the answer. As children grow older, their questions become more complicated. You (as a parent or a teacher) must teach them how to go and research the information.

How are we able to float on the Dead Sea?
Explore Science
The Dead Sea is over 8.5 times saltier than even the ocean! It also makes it easier for us to float in the Dead Sea. Join us to explore this extraordinary phenomenon through a simple experiment.
Transcript - How are we able to float on the Dead Sea?

Hi! I’m Udai

And I’m Jayan

And we’re reporting for V-Explore – video journal for children, by children

Udai: Jayan, have you heard about the Dead Sea. Also called the Salt Sea, it is a lake bordering Jordan and Israel.

The Dead Sea is over 8.5 times saltier than even the ocean! Its shores are 1,388 feet below sea level making it the lowest point on land.

Jayan: Why do we call it the Dead Sea?

Udai: The high amount of salt makes in difficult for animals to survive here.

But Jayan did you know that this salt makes it easy for us to float?

Jayan: Cool! Let’s do a simple experiment to show how adding salt to water can increase the buoyancy.

Buoyancy: Buoyancy is the upward force that is exerted by the liquid on an object.

All you need is:

An egg

A bowl or glass of water

Lots of salt!

Udai: Come on! Let’s create our own Dead Sea in a glass!

Gently put the egg into the water. You will notice it quickly finds its way to the bottom! How can we now make this egg float?

Its simple! Just add salt.

Add a few spoons of salt into the glass and stir it gently until the salt dissolves. Careful, you don’t want to break the egg do you?

Let the water settle and watch the egg. You will notice it will start floating to the top. Add more salt if required.

The more salt you add the more the egg will float.

You can clearly see from this experiment that salt increases the natural buoyancy.

This is why it is easy to float in the Dead Sea!

Jayan: Isn’t this cool?

Udai: We hope you enjoyed this experiment. We’ll be back with more soon.

Together: Until then – keep exploring!

 

 

How can we defy gravity?
Explore Science
What makes a ball fall to the ground after you throw it up? Gravity. Watch our Explorers conduct a simple experiment to show what gravity is and how it works.
Transcript - How can we defy gravity?

How can we defy gravity?

Hi I’m Meher and I’m Udai

And we’re reporting for V-Explore – video journal for children, by children.

Today we’re going to show you an experiment that defies gravity.

We all know that gravity pulls everything down to the centre of the Earth. This is why rivers flow downhill and raindrops fall down from the clouds.

This experiment however shows how air pressure, or atmospheric pressure can sometimes help defy gravity.

Air, like us, too has weight. Air closest to the Earth’s surface is weighed down by the air above it. We call this air pressure.

So, let’s get on with our experiment.

Put the chart paper over the mouth of the glass, making sure that no air bubbles enter the glass.

Turn the glass upside down.

Slowly remove your hand. The water stays put defying gravity!

This is because the pressure of the air pushing up the chart paper is greater than the force of the gravity pulling the water down!

Isn’t that cool!

I do hope you enjoyed the experiment!

We will be back with more soon

Until then Keep Exploring.

 

How can we use solar energy to create electricity?
Explore Science
We know that solar energy can be used to generate electricity. We use large solar panels to do so. But how do solar panels convert Sun's energy into electricity?
Transcript - How can we use solar energy to create electricity?

Solar Energy

Hi I am Saatvik and I am Devyani

We are reporting for V-Explore – video journals for children, by children.

Did you know that heat and the light from the Sun could be harnessed to generate electricity? Solar panels are large flat panels that convert light into electricity.

Scientists believe that just one hour of sunlight could be used to create energy that would last the entire human population a year! But this is if we have Solar panels that covered all of Earth!

Solar energy is green energy – this means it’s good for the Earth. It does not emit harmful gases that make our world polluted.

Today we are going to use tiny solar panels to power up a rover made by recycling a soda can.

 

All we need is:

  • A Solar Rover Kit
  • An old soda can
  • Screwdriver

The kit contains

  • A solar panels
  • 4 wheels
  • Car chassis
  • Front an back axle
  • Many different screws

 

Follow the instructions on the kit to assemble your super cool rover. You can ask an adult to help you as I have done.

 

Now, let’s take this green rover out in the sunlight. Let these tiny solar panels get some charge!

Look! It’s moving. The solar panel converts the energy from sunlight into electricity that then powers the motor. Isn’t that just epic!

I wish our cars could also run on solar energy!

In science terms: The solar panel converts solar energy into electrical energy. The motor converts the electrical energy into mechanical energy that makes the rover move!

Isn’t it amazing!

The same principles are used in powering large power stations. Only we use large turbines and huge solar panels.

I do hope you enjoyed the experiment!

We will be back with more soon

Until then Keep exploring.

 

Can energy really change forms?
Explore Science
Heat, light, sound, electricity -- are all different forms of energy. Did you know that energy cannot be created or destroyed?
Transcript - Can energy really change forms?

Mechanical Energy into Electrical Energy

Hi I am Udai …..

I am reporting for V-Explore – video journals for children, by children.

Energy is all around us. It makes the world spin around, helps us move and even keeps the wheels of this car turning.

Heat, light, sound and electricity are all different forms of energy. But did you know that energy never dies; it simply changes its form?

When you switch on a light, electrical energy turns into light energy. When you burn wood, chemical energy turns into heat energy! 

Today we will do a simple experiment to show how energy can be changed from one form to another. Today we will change mechanical energy to electrical energy!

On Camera

All we need is:

A Dynamo Torch kit!

The kit contains

- A toy motor
- 2 gears
- LED lamp
- Torch casing
- A crank or handle
- Wires
- And screws!

Follow the instructions on the kit to assemble the torch. You can ask an adult to help.

Now, turn the handle of the dynamo as quickly as you can!

Look! Your hand has powered the light.

In science terms: Your moving hand (mechanical energy) gets converted into electrical energy. Of course the food we eat gives us our energy! I am already hungry!!!

The toy motor contains a central axle with wires coiled around it. There are two small magnets on either side of the axle. The axle itself is connected to the gears and the handle. The moving of our hands (or mechanical energy), helps turn the gears and axle inside the dynamo.

An electric current is generated when the axle spins between the magnets, lighting up the lamp!

Isn’t it amazing!

The same principles are used in powering large power stations. Only we use large turbines and energy from wind, water or from the burning of fossil fuels.

I do hope you enjoyed the experiment!

We will be back with more soon ….

What is convection?
Explore Science
Ever wonder how a heater that sits in a corner of the room manages to warm the entire room
Transcript - What is convection?

Hi I’m Udai and I’m Uday

And we’re reporting for V-Explore – video journal for children, by children.

Uday: Udai, did you know that heat travels from one place to another?

Udai: Yes! Heat moves from hotter to colder objects.

Uday: That’s why a steel spoon gets hot when you leave it in a cup of hot milk.

Udai: Absolutely. Heat can spread through liquids and gases. This is convection.

(Graphic text: Convection is the transfer of heat through the motion of particles such as water or air.)

Today’s experiment is all about convection.

Voiceover:

Have you ever looked at a pot of boiling water closely? The water bubbles up, as it gets hotter. This is because when you heat water in a pot the water at the bottom becomes hot first. The warm water rises and cooler water comes down to take its place.

Let’s see how this works with a simple experiment.

All you need is:

  • A glass
  • A heat-proof bowl
  • An eye dropper
  • And some food colouring

Voiceover:

Fill the glass with cold water and let it stand until the water becomes still.

Pour some hot water into a bowl. I would recommend that you get an adult to help you with this part.

Now place the glass in the bowl of hot water and wait until the water is completely still.

Put some food coluring into the water. See how the food colouring moves around? This is because of convection. The warm water is moving up and is replaced by cold water.

Wasn't that cool!

Did you know that convection exists even in nature? 

Land and sea breeze are results of convection. Visit our website www.myteamexplore to know more about convection.

I hope you enjoyed our experiment.

We’ll be back with more. Until then – keep exploring!    

Hovercraft (Friction)
Science Experiment
Our explorers have fun doing science experiments that help them understand basic concepts they learn in school. In this episode our V-explorers take a closer look at a Hovercraft and how it moves!
Transcript - Hovercraft (Friction)

How do hovercrafts move?

 

Hi I’m Meher and I’m Arhan

 

And we’re reporting for V-Explore – video journal for children, by children.

 

Today we’re going to show you how to make a hovercraft.

 

A hovercraft is an amphibious vehicle – it can travel on both land and water! Hovercrafts have huge fans that blow air under them and help them float. This is why they are able to move on any surface.

 

Let’s see how it all works!

 

All you need is:

 

  • An old CD or DVD disc
  • A balloon
  • A pop-top cap
  • Super glue

 

  1. Cover the hole in the centre of the CD with a piece of tape and poke about 6 holes in the tape with a small needle. This will slow down the flow of air and allow your hovercraft to hover longer.
  2. Stick the cap to the center of the CD with some super glue. Make sure that the cap is glued on tight to stop air from escaping from the sides.
  3. Blow up the balloon all the way and hold it tight by the neck. Don’t tie it!
  4. Make sure the pop-top is closed and fit the neck of the balloon over the pop-up part of the cap. This is usually easier to do with 2 people!
  5. Place your hovercraft on a smooth surface, pop the top open and watch it go!
  6. The air from the balloon flows through the pop-top and under the CD. The air lifts CD and reduces friction between the CD and the surface making the CD hover. Hovercrafts have huge fans that blow air under them.

 

I hope you enjoyed the experiment! We will be back with more experiments soon. Until then keep exploring!

 

 

Mystery Markers

Transcript - Mystery Markers

Colours are made up of different dyes

Hi I’m Samaira and I’m Amaira

And we’re reporting for V-Explore – video journal for children, by children.

Today we’re going to show you an experiment called Mystery Marker.

 

To tell the truth, there’s nothing really mysterious about this experiment.

It’s just pure science!

Do you know that red, yellow and blue are primary colours? All other colours are a mixture of these three colours.

Mixing yellow and blue gives us green, and we get purple when we mix blue with red!

Let’s try our Mystery Marker experiment to see how it all works!

 

All you need is:

A bowl of water

A black marker

Strips of tissue paper

 

Draw a wavy line an inch from the bottom of the paper strip. You can use any colour you want except red, yellow and blue. We are using a black marker pen.

Now dip the strip into the bowl of water. Be careful! Only the bottom edge of the paper should be in water and not the wavy line you drew. 

You can now see the water slowly creep up the strip. 

Look! The line we made begins to spread, and now we can see the different colours that make up black. Isn’t this cool!

I hope you enjoyed the experiment! We will be back with more experiments soon. Until then keep exploring!

Light travels in a straight line

Hi I am Udai …..

Did you know that light travels in a straight line away from the source? The lines are also called rays.

Here is a picture I took one day when I saw the Sun’s rays shining through the clouds. You can clearly see the straight lines!

You can even see these lines when you use a torch when it is dark.

Here is a simple experiment that shows is that light travels in a straight line.

 

All we need is:

5 square pieces of paper

scissors

modeling clay

ruler

torch

 

Take four of the 5 square papers and cut a circular hole in the center. You can use a compass to make the circle.

Ask an adult to help with the cutting.

Leave the 5th paper uncut. Draw the target around the center. Remember to ensure that the red circle is in the center.

Line them 20 cm apart with the target at the end of the row. Use the modeling clay to make little stands. Ensure they are in a straight line and you can see the target through the holes.

We need to make the room a little darker now.

Switch on the torch, you will notice that the light shines through the holes and lights up the target. Isn’t that super cool???

There, now we have seen that light travels in a straight line from its source.

I do hope you enjoyed the experiment! We will be back with more soon ….
