Lab Safety and Integrated learning in the classroom
Updated: Dec 7, 2024
Lab safety should be taught to students prior to doing any experiments. Students should be taught the proper use of safety equipment and how to handle hazardous materials. They should also be taught to report any unsafe conditions or accidents.
For week 7, we reviewed the SAFETY IN ELEMENTARY SCIENCE AND TECHNOLOGY A Reference Guide for Elementary School Educators by STAO. The document is connected to the science strands of the Ontario Curriculum. It gives clear instructions on safety procedures to follow while conducting any experiment in any strand. Having an understanding of this policy document will help us in our future teaching practice. Teachers play a crucial role in ensuring lab safety by actively supervising students during experiments and providing clear demonstrations of safe practices. They are responsible for reinforcing safety protocols and ensuring that all students understand and adhere to them. Additionally, teachers must regularly inspect lab equipment for any potential hazards and ensure that the laboratory environment remains safe and conducive to learning.
Reflection
Ignoring lab safety protocols can lead to severe accidents, including chemical spills, fires, or exposure to toxic substances. Such incidents can result in injuries, long-term health issues, or even fatalities for students and staff. Additionally, neglecting safety measures can cause damage to lab equipment and facilities, leading to costly repairs and interruptions in academic activities. For example, if a glass is broken, there is a procedure to follow, and every board has its own policy and procedures; therefore, it is always recommended to be cautious and follow the lab safety protocols.

Safety rules to remember
As an educator in training remembering these safety rules is a must, also these safety rules has to be reminded to students before engaging in any STEM hands-on activity.
Popping soda bottles
In order to learn how and why lab safety is essential, we conducted a quick experiment where we mixed baking soda and vinegar in tiny plastic jars and locked the lids. Within a few seconds, the forming gasses inside the jar forcefully eject the lid. If someone is not quite mindful, the popping lid can cause an injury to the eyes or face. This experiment clearly demonstrated the importance of lab safety in preventing potential accidents.
Integrated Learning in the classroom
Guideline No 1. Think Big and consider these questions to guide our teaching.
What are the specific student outcomes to address?
Which subjects could provide meaningful contexts for content and skill development? What are the curriculum expectations that speak to those intended student outcomes?
Are there current events in the media that would support a choice for student inquiry?
What opportunities can be created for students to develop all four roles of the literate learner in an integrated unit of study (and through the gradual release of responsibility)?
Are the print and/or media resources available in the school suitable for use with diverse learners?
Are all the language strands integrated in a variety of authentic contexts?
Which single or blended text forms are most appropriate for developing students’ thinking and communication skills?
Guideline No. 2 - Think real-world problems and issues and even events
Do the tasks have multiple purposes?
Do the tasks reflect a range of opportunities for students to practice and develop their communication skills beyond a learning-to-read-and-write context?
Will students see genuine purposes in the ways they are accessing and communicating information?
Will students see themselves reflected in the resources available for the purposes of this learning?
Guideline No. 3 – Think broad context about literacy
• authentic, real-life contexts relevant to the students’ lives
• entry points for all learners
• opportunities to extend and challenge student thinking
• opportunities for student-identified inquiries and choice
• collaborative learning structures that build independence and understanding
• authentic opportunities for communicating thinking in a variety of mediums
• use a variety of forms of texts and text forms including oral, multi-modal and media
• development of subject-specific vocabulary
