PERIOD TWO - Science 8
Safety in the Laboratory
It is expected that students will:
- through discussion, start to build an understanding and apply skills and processes of science such as:
- hypothesizing
- controlling variables
- observing and measuring
- classifying and generalizing
- interpreting data
create a list of safety rules for use during laboratory experiments identify dangers in particular procedures and equipment, and taking responsibility for their safe and accurate use know what WHMIS is and recognize the WHMIS labels
Demo on the "changing solution" oscillating reaction.
Discuss the branches of science. Focus in on just chemistry to see the fields of Chemistry. Look at the various career choices you can have in Chemistry.
Take notes on and discuss the "Scientific Method".
Students will try to determine the safety issues in various laboratory scenarios created by the teacher using students in the class and / or an overhead sheet.
One-pair-four activity will be done to determine a class list of safety rules for the science laboratory. Students will brainstorm individually, then with a partner and finally in a group of four to decide on the most important safety rules in the lab.
Students will write out the Master List in the form of a contract and will sign and date it. If students do not follow the rules, they will not be permitted to take part in the Laboratory Experiments.
FOR HOMEWORK : On a colored poster, identify and illustrate one danger in a particular procedure or piece of equipment in the science laboratory. You will present it NEXT class. Choose from this list, be sure to check the marking criteria.
Demonstrate proper procedures for safety equipment in lab, explain and discuss proper use of safety glasses, shower, aprons, 1st aid kit, fire extinguisher, fire blanket, and eye wash station
Discuss the importance of a standardized system for labeling hazardous materials and give notes on WHMIS.
