Why this is our science class

The most spicy class. guess!

In which we all loose our stress

Seriously I am not joking at all

Our science class make me fall

The moment she entered our class

our heart got sensitive like glass

Suddenly she changed my seat

That's how we greet

Then she gave me a big lecture on it

And I was saying 'shit'

Then she started telling me about the qualities of green vegetable

To understand her , I am sorry but I was not able

Then suddenly she told me about her cooking

so fearful i was looking

Because of her quite scary lecture

her kindness make my heart fracture

I never want a teacher like this

This science class make me bliss

In our science class if only moral lessons take place

 It is the only reason of my fearful grace

 Can you tell me why this is our science class
