__**Science Laboratory Rules**__
Before we go to the science lab for experiments, we must first know the Do's and Don'ts in the science laboratory. The following are the rules that we need to follow when in the laboratory;

__**Do's**__
__﻿__
 * Always follow your teacher's instructions carefully
 * Keep your notebooks and paper away from heating equipment, glassware, chemicals and flames
 * Tell your teacher immediately if you cut or burn yourself
 * Tell your teacher immediately if you break any glassware or spill chemicals. Spillages, even of water, need to be cleaned up without delay
 * Wait until hot equipment has had time to cool before putting it away
 * Leave all benches and tables clean and dry when you have completed your experiment
 * Wash your hands after you have handled any substances in the laboratory
 * Point test tubes away from your eyes and your fellow students
 * Wear safety glasses while mixing or heating substances

__**Don'ts**__

 * Enter the laboratory without your teacher's permission
 * Run, push or behave roughly in the laboratory
 * Eat or drink in the laboratory
 * Smell or taste substances unless instructed to by your teacher. When you do need to smell substances, fan the odour to your nose with your hand.
 * Put paper, matches or other solid objects in the sink
 * Pour substances down the sink.(Always follow your teacher's directions about the disposal of substances)
 * Mix chemicals unless you have been instructed by your teacher
 * Look directly into the top of a test tube, beaker or flask

**__Science Apparatuses__**
There are many apparatuses in the science laboratory. The teacher gave us some worksheets to know what apparatuses there are in the science laboratory. The following are the ones that are introduced to us: There are a lot of different kinds of apparatuses in the science laboratory, as you can see from the list above. However, the purpose or reason why a particular apparatus is used is different from other apparatuses.
 * Thistle funnel
 * Retort stand
 * Filter funnel
 * Bell jar
 * Tripod stand
 * Beaker
 * Flat-bottomed flask
 * Test tube
 * Measuring cylinder
 * Pipette
 * Burette
 * Conical flask
 * Water trough
 * Round-bottomed flask
 * Crucible
 * Gas jar
 * Evaporating dish

Reflection After this lesson, I learnt about the different kinds of apparatueses that you see in the science lab. As we will be visiting the science lab once a week for experiments, it is very useful to know the apparatuses and this will help us when we are doing our experiments. I also learnt about the dos and don'ts while in the science lab. After knowing how to allow myself to work in a safe environment, I feel very relieved that I will be safe and sound inside the lab so long as I follow the rules.
