Safety Precautions

Before the group started the experiment, safety was a very important issue to worry about, as, in a science laboratory, the students worked with glass, chemicals and other dangerous equipment and substances, and thus precautions always have to be taken.

1.

The first precaution taken followed was to use proper shoes and not sandals, flip-flops, etc. This is important since a substance or a piece of equipment might fall on the floor and, by wearing shoes, the students' feet were protected .

2.

Another important precaution was to wear safety goggles for eye-protection. When doing an experiment, observation of the processes are always necessary and, if an unexpected happening occurred, such as a violent reaction or a piece of equipment breaking, 

 3.

When the results on some measuring equipment such as a measuring cylinder or a thermometer had to be read, it was done similarly to the picture above, at eye level, to avoid parallax. However, it is necessary to maintain a certain distance from the equipment, especially if it is a dangerous/ harmful substance being measured or if the equipment being dealt with is fragile.

 4.

When working with boiling tubes,the students made sure always to point it away from people and themselves, thus preventing them from hurting themselves is a sudden, unexpected reaction occurred. (Note: This picture was takes before the group decided to change part of its experiment. The previous changes section of the experiment dealt with investigating boiling points, which explains the equipment being used above.
