Expirements can be very dangerous at times, and not knowing how dangerous some the equipment is can end in minor or serious injuries. Chemicals for instance can be deadly and if you don’t understand what they’re made for or how they effect you, you shouldn’t be messing with them. You should always wear goggles and gloves when handling deadly chemicals. Fire is another hazard when working the lab. They say don’t play with fire for a reason, you could end up with serious burns if you are not careful with fire. Another hazard is some of the equipment and sharp objects. When dealing with knives or any other sharp objects, you should always keep the sharpened part pointed away from you and any other person. I promise the science teacher doesn’t want to deal with a kid whining over a cut because they were playing with a sharp object. When in class, listen to directions, pay attention, be careful, and be smart.
