so you understand the concept they are trying to teach. i know i am a kinestetic learner (hands on) so i have to do something to understand it.
It is important to listen to your teacher in a science lab because there is some very dangerous stuff in there which could harm you, so if you listen to your teacher, she/he can tell you what to do but safely!
Always.
A science lab
The science teacher gave a demonstration of the upcomeing lab.
You don't mess with the gas without the teacher's permission. You don't mix chemicals without goggles or without the teacher's permission. You don't horseplay around in the lab.
in my opinion you should tell the teacher immediately
make a stink bomb in the science lab, then she'll leave
"My science teacher," would be, "Mi profesor de ciencias."
I would put out fire safely in a science lab by spreading Carbon di oxide gas on the fire
What the teacher tells you to do. In order to be safe, you need to follow directions carefully and pay attention to what you're doing.
Please tell your teacher and also report it at the main office and see the nurse.
The word Lab in the terms of science (not the dog) is Laboratory.
