LAB SAFETY
Activate Learning
Start the lesson by directing the students to safety features within each laboratory. Ask them to discuss amongst themselves what are those items for and why. Distribute the safety regulation forms (digital) to the students and go through each of the items with them. The slides are found here:

Promote thinking and discussion
Using the facilities within the laboratory, provide a few scenarios so that the students can start thinking about what to do or NOT to do in the laboratory.
Examples :
Scenario 1: A fire started in the laboratory. What are the considerations before implementing a solution?
Scenario 2: One or more students were choking and coughing in the lab. What are the actions to be taken immediately?
Facilitate Demonstration of Learning
Students either individually or in groups to provide solutions or actions to each of the scenarios.
Monitor and provide feedback
Teacher will listen to their responses and provide the guidance to what should be the correct approach.
Examples:
Scenario 1: Considerations: What is the type of fire? Oil fire, Combustion, Chemical fire, or Electric fires. What are the different approaches? Isolation, Sand bath, Water, Fire Blanket, CO2 fire extinguisher.
Who to handle the situation? Student, Teacher, other school adults, Professionals (fire fighter)
Scenario 2: Is there an immediate risk to the student(s)? Evacuate the affected student(s).
Is there an immediate risk to other student(s)? Evacuate all the students within the affected area(s).
Is there a need to seek First Aid help? Seek help from teachers or other first-aid trained adults.
EXPERIMENTAL PREPARATION
Activate Learning
Start the lesson by asking the students how are they going to proceed with their experiments? Should they prepare some equipment and materials that relevant to their investigation?
Promote thinking and discussion
Get students to discuss within their group on what are they supposed to have prepared for the investigation.
Facilitate Demonstration of Learning
Direct the students to use/download the equipment request form to prepare for their lab requirements.
Highlight to the students that:
(a) Equipment will be provided by the school. Should there be a limited set, they have to draw out and return the equipment after every lesson. They should read the instructions carefully before carry out their measurements.
(b) Expendables will be provided by the students themselves. However, they should not spend more than $10 per person or $30 per project. There must definitely be low cost materials to carry out their project(s).
(c) Certain chemicals will be provided by the school. However, they have to obtain the items directly from the Laboratory Staff in small quantities each time they need to carry out the experiment.
Monitor and provide feedback
Teacher to check the equipment and chemical request forms that students have prepared for their request.
Equipment request form:
The equipment request form (hardcopy) are available at the Laboratory. Please use a hardcopy when submitting requests.
Spare forms are found here:

Students are directed to prepare their logbook by filling in the basic information for the group.
The online ISS log book is found in the google drive folder that students have access to.
