shake the container vigorously smell a very small amount of it look up the name in a science book test a small amount to see if it feels slippery
I gave my students this multiple choice question: A student finds a bottle that is labeled with a long chemical name. What is the best way for the student to learn more about the chemical properties of this substance?

Only one answer is correct among these 4 choices:
- shake the container vigorously
- smell a very small amount of it
- look up the name in a science book
- test a small amount to see if it feels slippery

Could you tell me which one is correct?

look up the name in a science book
