1a. The eye wash station is used in the event of a substance getting in the eye(s). The eye wash station has two faucets to project water into the eyes to rinse out the contaminant.
1b. A fire blanket is used to put out small fires by covering the flame and cutting of its oxygen supply.
1c. A lab shower is used in the event of contamination or fire on the body. Standing under the running water will help get the contamination off and will put out a fire.
1d. A chemical spill kit is used for just that, but depending on what chemical was spilled you need to use the opposite ph to clean it up. For example, if the spill is acidic, counter it with a base, and if the spill is a base, counter with an acid. …show more content…
The biological spill solution is 10 percent bleach solution. It would be used for cleaning surfaces and equipment before and after use to kill microorganisms that can infect yourself and other things.

2a. A broken glass container would be used to store glass in the event of a slide, cover slip, graduated cylinder, or other glass equipment breaking. If this glass wasn’t stored in this container and was put in a normal trash container then it could tear the bag and/or cut the person trying to handle it.
2b. A biological hazards materials container is used to store any materials infected with any bodily fluids or other possibly infected materials. For example if you needed to clean up some blood you would wear some gloves and use a towel with the 10 percent bleach solution to wipe down the area thoroughly multiple times. Then you would use the previously mentioned container to discard the two items used in the cleanup and anything else that was contaminated. All this is done to prevent the spread of infection or disease.
3a. 5 feet 9 inches equals 69 inches. 69 x 2.54 = 175.26 cm
3b. 8.5 inches multiplied by 2.54 equals 21.59 cm, then move the decimal to the left five places to get kilometers which would be 0.0002159 …show more content…
The experimental group of rats is 68.9 grams, so to get the difference in the two groups average weights you would subtract the control groups weight (60.4 g) from the experimental groups weight (68.9 g) which would give you a difference of 8.5 grams.
4a.1. (38.5 x 9/5) + 32 = 101.3 degrees Fahrenheit
4a.2. Anything above the 98.6 would be a fever, so yes, the student is running a fever.
4b. (160-32) x 5/9 = 71.11 degrees Celsius
4c. (29 x 9/5) + 32 = 84.2 degrees Fahrenheit
5. The purpose of the control group is to see if the factor being manipulated in the experimental group is causing a difference in that group’s results compared to the control group’s results. If you just ran one group with the single factor being manipulated that was thought to bring about a certain outcome then you wouldn’t know if the manipulated factor is causing the results or if the outcome would’ve happened anyways. Therefore, a control is needed to compare the
