Our future responsible

Description
I had spent a whole school day in the science laboratory for my observation. I went through to every cupboard in the lab to observe the maintenance of the science lab since the inventory record book was lost. All the science apparatus were labeled and kept in the safety area in net arrangement.

Evaluation
In the science lab, there were no any chemicals and materials available apart from the science apparatuses which are in old and cover with dust condition. The science teacher saying that the science lab was much less utilized because the level one students were seldom went to the science lab and the level two students were much less exposed to the experiment which was using chemicals. The waste chemicals and materials are disposed off to the sink and solid materials are disposed off to the dustbin which provided in the science lab.
The charts in the lab were never be updated and I found that there was no any rules and safety guide that listed and shown in the lab. From this condition, I realized that the jobs done by the school teacher were not good enough as a professional science teacher in maintaining the safety of the science laboratory.

Analysis
The science teachers must act as a reasonably prudent person would in provide and maintaining a safe learning environment for their students.
Science teachers’ duty to maintain a safe learning environment while providing science instruction also must be shared by the school leaders, teachers and students. It is vital that the teachers communicate regularly and fully on the essentials of safe instruction for students.
The laboratory environment presents unique types of dangers that teachers must guard against. The science teacher has a duty to anticipate foreseeable dangers and take precautions to protect the students from possible harm. This duty extends primarily to five areas of responsibility.
1. Providing adequate supervision over student activities while the experiment is conducting.
2. Giving students adequate instructions to perform the tasks required of them.
3. Providing clear safety rules, enforcing the rules on a consistent basis and warning students of possible dangers in performing the activity.
4. Maintaining in proper working order equipment to be used in the laboratory.
5. Providing safe laboratory facilities for the performance of the laboratory task.

The teachers must be physically present at all times to supervise students wherever chemicals or laboratory equipment are being used.
Besides, the science contract should clearly spell out the rules of the science laboratory that students must always follow. The rules listed on the safety contract must be discussed and reviewed at every possible opportunity. Student lab reports must document key safety rules they are expected to be followed when performing the lab. Safety must be reinforced on a daily basis.
It is the teacher’s responsibility to specifically identify, warn and instruct students of potential hazards that might occur within the laboratory and supervise students by monitoring the proper use of laboratory technique and safety equipment by the students.
On the other hand, the teachers should always inspect all equipment and glassware before use to ensure all equipment must be in good working order.
It is the teacher’s duty to inspect and maintain in proper working order safety equipment to be used in the laboratory. It is also the teacher’s duty to provide a safe facility for the performance of the laboratory task.

Conclusion
The science laboratory is essential for the effectiveness teaching and learning of science. A school laboratory investigation is an experience in the laboratory that provides students with opportunities to interact directly with natural phenomena or with data collected by others using tools, materials, data collection techniques, and models. As professionals, teachers of science have a duty of care to ensure the safety of students.

Action plan
Before every experiment conduct in the lab, I should review the teacher and the student responsibilities for laboratory safety. This will improve the safety of activity and greatly reduce an accident occur.
