Yes, I do wonder about many things around me. Some of them are listed below:

(i) How does the colour of a leaf change from green to yellow or orange?

(ii) How do our organs differentiate between oxygen and carbon dioxide?

(iii) How do the plants develop a suction pull to absorb water and nutrients from the soil?

(iv) Why is there no such place on our planet from where we can see its real elliptical shape?

(v) Why does honey not degrade with time?
