Congratulations to the chemistry teacher on the last call

Violent reaction
Gives the last call,
He is your chemistry teacher,
It will cheer you up.

He became a catalyst
For joy, fun
And you are from us today
Congratulations.

All experiments have been completed,
Laboratory tests have been passed,
And they are waiting for us ahead
The days are summer, free.

We wish you to please
Your last call,
And in the fall you come to us
We were in a hurry to go to class.
