### JUNIOR TINKER LAB AT HOME AT A GLANCE

Unlimited Play, Fun, Innovation,Creativity, Experimentation

### Introduction to Electronic Bits

Before doing the activities, understand about different Electronic components and how they can be connected. Electronic components work only when they are connected properly.

### How to connect Aligator Clips?

This video shows how to connect aligator clips to electric wires. Incase the wire comes off from the clip then its better to know how to connect it again to the aligator clip. These are basic skills which everyone should know while dealing with electric components.

### 3v & 9v Battery Holder

In this video, understand how to use 3volt and 9v battery holders. They act as the power house for all the electric experiments.

### Make your own Vacuum Cleaner

Want to keep your study table clean from the fine dust? Why not make your own mini-vacuum cleaner and also understand the science behind it.

### Scar's Car

Make your own simple car using the geared motor. Observe the significance of power on the back wheels and direction on the front wheels.

### Wind Turbine

Make a working model of wind turbine and unleash the power of wind. Also you can blow into the turbine and check how much is your lung capacity. Challenge your friends on who can blow till the top.

### Bulge of Earth

Do you know its the rotation of earth while cause it to bulge at the centre. What is the force acting on it?
Make this fun activity and understand the science behind it.

### Deep dive - mini Submarine

In this project you will investigate how submarines dive and surface by changing their buoyancy in the water.

### Buzz me not!!

If you loved the game "Operation" as a child, and want to continue on your path of supreme hand-eye coordination, give this buzzing electronics project a try. What's great is you can change the path every time.

### Robo Walker

Super exciting Robo Walker will be your best friend once you make it. Though it looks simple, its a combination of circular, linear and to-fro motion.

### Wave generator!

Its so fascinating to observe waves. Infact Light, Sound have wave properties. Why not create few waves and observe the change in frequency amplitude in a fun way.?

### Centrifuge Mania!

The high speed motor gives the required centrifugal force to separate two materials of different densities. Infact this technique is used to separate components of blood - RBC, platelets & plasma - from each other.

### Hit the Brakes!!

Friction can be your friend or enemy. It depends on how you use it. In the case of Automobiles, friction is our very important friend. Why?? Make this exciting project and explore the function of brakes.

### Simple Motor

Electric motors work due to electromagnetic interactions. Why not make one and observe how electricity and magnetism work in unison.

### Looking through Insects eye

Most insects have compound eyes which consist of many (up to thousands) tiny lens-capped 'eye-units'. Together, these work to create a low resolution, pixelated image

### Fun Turning Car

Make a simple fun turning car using geared motor. Observe the importance of front wheels for changing the direction of the car and back vehicles to get the power for the car.

### Crazy Bug

Having symmetry and balance is very important. But sometimes being off centered also helps. Same principle is used in many house old things like massager , phone vibration etc.

### Art of Animation

Children love cartoons. How about making a small motion wheel and understanding the science behind moving cartoons.

### Magneto Tracer

Using the power of magnetism and also friction lets trace magnetic materials. Bend the magnetic material in whatever shape you want and see the metal rod tracing the shape.

### Floating Pencil

One of the famous and most watched activity on YouTube. But why just watch it , lets do it. Once you make the pencil levitate in air try to spin it and observe how freely it rotates.

### Yoga Magnet

Nice interesting activity where you balance the magnet in air using magnetic attraction and gravitational force. Also there is a common misconception that all metals attract magnet. Test what are the magnetic materials in a fun way.

### Scars Shooter

Make your own simple shooter using the power of compressed air. Change the directions using the magnetic connector.

### Make Table Fan, Light

One of the most simple yet exciting activity for children. Once they know how to make a table fan, light, buzzer and control it using switch then they can extent it to their own ideas of making a cooler or controlling it using solar panel or other sensors.

### Simple Metal Detector

Lets use the property that metals are good conductors of electricity and make a simple metal detector. There are different ways to make metal detector and this is one of the ways.

Why only draw circuits on paper. Instead lets make our own circuits and explore open and closed circuits. Lets connect LED's , Motor, fan , buzzer etc and play with the electronic components.

### Electric Friends & Enemies

Do all materials conduct electricity? Make your own set up and test conductivity for different materials. Bring materials in and around you and test for conductivity.

### Earth is not flat

How far can we see a ship in sea? Is it the distance or the curvature of earth which makes the ship disappear? Try this interesting activity and understand the science behind it.

### Squishy Circuits

By using conductive and insulating dough, you can create sculptures with embedded lights, motors and buzzers. This project is great for younger innovators because it utilizes a material they already know - PlayDoh.

### Make your own 3D glasses

Making your own 3D glasses is so easy to do that you can whip them up just before a movie

### Playing with Magnetic poles

Magnet play is one of the first simple science activities that a child can experience because magnets are easy to use, fun, and common!

### Lens Detective

Lenses bend light in useful ways. Most devices that control light have one or more lenses in them.

### Lets make a Parachute

A parachute is a device used to slow down an object that is falling towards the ground. Why now make one and understand the science behind it.

### Magnetic Lines - Hairy Fashion

Magnetic fields by themselves are invisible to the human eye. Lets use iron filings to decode the magnetic fields.

### Slipping Paper

Using the frictional force observe how smoothly the paper slides between the roller and the surface. The rubber rollers inside the printer work in similar fashion.

### 3D Projection - Hologram

The activity creates a 3D-like illusion for the viewer and makes an image or video appear as if it were in midair.

### Colour wheel & Illusion disc

Light is all of the colors in one: white. When the wheel spins up to the right speed, the colors blend into a near-recreation of white light.

### Marble Run

Making a marble run is a great way to get creative as well as learn a few simple laws of physics.

### Bird in a cage - Illusion

Trick your eyes into thinking you can see a bird in a cage, when you really only see one or the other.

### Disappearing words

Have you ever wondered why objects have different colors? Have you also ever wondered what it would be like to work as a secret agent and send secret messages to people?

### Static Mixer

Make a mixer in which you can electrically charge the thermocol ball and observe how it attracts a balloon. This the same why how lightning works.

### Electric Man

Does our body conduct electricity? Try out this fun and safe experiment.

### Electroscope

Have you ever wondered why objects have different colors? Have you also ever wondered what it would be like to work as a secret agent and send secret messages to people?

### Fun with Gears

Gears are wheels which slot together. If the gears are of different sizes, they can be used to increase the speed. Cars and bicycles use gears to achieve amazing speeds our bodies could never match without help.

### Pulley Magic

A pulley is a wheel that you loop a rope over. The key point of pulleys is that they redirect force. Do this interesting activity and understand the science behind this simple machine - pulley.

### Guess the Secret word

Till today, Morse code is used by the navy, military and amateur radio services. The first change in the Morse Code after World War II, came in December 2003 when the Morse code included the @ symbol. The code for it is . _ _ . _ _
