Another year of exuberant participation in GRIP and exhibition of creativity through various activities!

With outstanding submissions from all the participants, it becomes really difficult to choose the best from them. But congratulating everyone for their participation, with heavy heart, GRIP announces the chosen top activities from them all.

Biology Activity


Haven’t you heard about UFOs and aliens, also about abductions…? So many stories, conspiracy theories and what not. Isn’t this about time that you gave it your own little mixup and tried your hand at it. C’mon now and think about how an alien would be if you designed it? Let’s do this fun activity and explore your imagining powers.


Design the most realistic alien and list the authentic ways of it surviving on Mars keeping in mind the climatic conditions of planet Mars.

Mathematics Activity


Take a square sheet of paper 20cm by 20cm, cut identical squares from each corner, and fold up the flaps to make a box (without a lid).


  • What is the volume of your box?

  • What different volumes can you make by varying the size of the squares you cut out?

  • What is the maximum possible volume of this type of box that can be made from a 20cm by 20cm square of paper?

Now try starting with different sized square sheets of paper.

  • Can you find a relationship between the size of paper and the size of the square cut-out that produces the maximum volume?

Physics Activity

Measuring Around…

“All objects near the surface of earth accelerate with same acceleration”

Are we sure?
People like Galileo won’t just blindly believe it! They would test it-

‘Let’s go to the top of leaning tower of Pisa, let’s drop two bodies with different masses, and let’s see if they actually fall at the same time.’



That’s how you do Physics! And not just that, one can also calculate the value of acceleration due to gravity by using second equation of motion, s=ut+12at2, to obtain 

H = 12gt2

All you have to do is-

-Measure the height of the tower
-Note the time of fall using a stop watch

Measured height

Time of fall

Calculated ‘g’










Hence, average calculated ‘g’ comes out to be 10.34m/s2. Though the error comes out to be of 5%, it has more or less verified the value of ‘g’ as expected.

Now, for this activity, we are going to be Galileos. But let’s move ahead of finding the value of ‘g’ and let’s setup a cool experiment ourselves and see how our own predictions on the basis of laws of Physics work out in real life.


  1. Setup an experiment to study the motion of an object(s)/ some physical phenomenon

  2. Predict the motion, or the phenomenon, on the basis of known laws like Conservation of Energy, Conservation of Linear Momentum, Laws of Motion, or equations of motion, etc.

  3. Record the video of experimentally verifying if our predictions (or phenomena) are correct. 

  4. Make a report of the whole experiment
