In today’s world, hundreds of appliances use a motor. So, friends today let us make a very simple DC motor with house hold materials. You need a battery, safety pins, insulated copper wire, magnets, old bicycle tube, scissors and a cutter.
Take a 1.5 meter of insulated copper wire and wind it around the battery. Move it around 10 turns and remove it from the battery. Take one end and tie a knot and stretch it out. Repeat the same at other end. For equal distances of the weight both the knots should be diametrically opposite. Trim both ends to 3 cm. Now take a cutter and scrape off three sides on one end such that one side is still insulated. On other diametrically opposite side scrape the insulation entirely.
The coil is ready now.
Next take an old bicycle tube and cut two broad rubber bands. Stretch and fix these rubber bands on battery and tuck in the magnet and the safety pins. The motor is now ready. If you place the coil in this assembly it starts.
A motor is a device that converts electrical energy into mechanical energy. When the coil is connected to the battery current passes through it which makes it electromagnet. This electromagnet has its north and south poles. The permanent magnet placed in the vicinity of the magnet gives it attractive and repulsive kick depending on the polarity of both the magnets and the coil rotates.
As you might remember as we purposely left the insulation at one end. This precisely contributes switching the current on and off for every rotation.
Current passing, magnetic field and number of turns are the three important factors.
Wasn’t it simple? So make your own dc motor and have fun!

Some of you may have difficulties in understanding Highest Common Factor (HCF) and Least Common Multiple (LCM). But these mathematical concepts can be understood easily with some activities. Let's find out!

HCF: The numbers that can divide a given number completely (leaving a remainder of zero) are called its factors. The highest common factor (HCF) of a group of numbers is the largest common factor of the numbers. Lets find out how to find HCF of two numbers by some performing activities.

PRIME FACTORIZATION 0:59
One method of determining the HCF of two (or more) numbers is by representing both numbers as products of their prime factors. The HCF is a factor that is common to both/all numbers and also the largest such factor. Hence, we multiply all the prime factors that are common to both/all numbers in order to obtain the highest common factor of the two numbers.

CONTINUED DIVISION 3:02
Another method of determining the HCF of two numbers is by continued division. It is also called Euclid's Algorithm. It is a process by which we repeatedly eliminate the smaller number from the larger number until we get an equal number on both sides.

The steps to follow in continued division are as follows:
1. Make two columns and write one number in each column.
2. Compare the two numbers. Subtract the smaller number from the larger one.
3. Compare the two numbers again. Subtract the smaller number from the larger one.
4. Repeat this step until the numbers on both sides are equal. This number is the HCF of the two numbers we began the algorithm with.

Try both these methods with many different pairs/groups of numbers!
For smaller numbers, try to guess what the HCF/GCD would be and check your answer.
Use prime numbers with composite numbers or pairs/groups of prime numbers. What do you observe about their HCF in each case?

LCM 4:33
The smallest number which is a multiple of two numbers is called their least common multiple (LCM). The activity described in the video visually explains what the LCM of two numbers denotes - it is the smallest number where the multiples of the given pairs/groups of numbers coincide, i.e. the smallest number which is a multiple of all the numbers we are calculating the LCM of.

Make your own number line and cut out many strips of paper, divide each one of them into intervals representing different numbers, and try to find the LCMs of different pairs/groups of numbers!

Once again, what do you observe when you calculate the LCM of prime numbers, or prime and composite numbers, or composite numbers? Are the prime factors of each number in the pair/group also somehow related to their LCM?"

Heat is a form of energy that gets transferred by various methods such as conduction, convection and radiation. In liquids, the heat transfer takes place by convection. Let's look at a simple activity to observe convection in action!

You need two glasses, some colour, hot and cold water. Take hot water in a glass and add some colour to it. Take cold water in another glass and place the CD on this glass as a lid. Now carefully invert the cold glass on the glass containing hot water with colour. The hole in the CD allows hot water to rise up as seen by the movement of coloured water.

Hot water is less dense than cold water and thus rises up in the fluid also transferring the heat with it. This form of heat transfer, called convection, happens in all fluids (liquid and gases) and is due to the actual motion of fluid particles.

If you invert the position of glasses, that is the lower glass contains cold water, and the top glass contains hot coloured water. You will notice that the colours do not mix as the coloured hot water is less dense than cold water and does not sink in cold water (move downwards).

This experiment demonstrates convection as a mode of heat transfer in fluids and also shows how convection only takes place in upwards direction.

We hope you enjoyed this experiment and learned something new. For more such hands-on science and mathematics activities subscribe to our YouTube channel IISER Pune science activity Centre.
