Reflection: Safety Mixtures: Characteristic Properties - Phase Change (day 3) - Section 6: Carry Out Plan

 

There are times to have fun in class and times to run a tight lab.  Anytime when you are running a lab with fire it is time to have a tight lab for the safety of the students.  I find that students can have problems with tight expectations in lab situations when they are used to looser structures.  To help students with this I make sure that students understand the rules at the very beginning of the class.

1.  You must stay in your seat when there is fire at your desk.

2.  You must wear you goggles.

3.  Raise your hand to get the attention of the attention of the teacher.

4.  Be professional in the lab.

The next important step I take in labs of this nature is that I don't give warnings.  The first time a student acts inappropriately, I ask them to leave and tell them they will need to finish this lab during their lunch time.  By not giving warnings or asking again and again for students to behave, I prove that I mean business and that I'm not going to accept crazy behavior.  

This might sound harsh...but consider the safety of all students.  Safety should come before fun when you are in a lab situation.
