LAB Safety

1. * Never work alone in the lab. * Do not eat, drink or smoke in the labs at any time. * Never wear roller blades in the lab. * Never mouth pipet. * Be sure that all hot plates, and Bunsen burners are off before you leave.

USE AND STORE REAGENTS SAFELY

* Always use secondary containment when transporting hazardous materials. * Always label bottles, tubes, dishes and other glassware! Tape and markers are provided for this purpose. Never write directly on glassware. * Discard hazardous waste in the proper container as soon as possible. * Do not leave uncapped bottles or uncovered dishes anywhere, even in the hood. If you have lost a cap or cover, get a new container, or use aluminum foil until a proper cover is found. * Make sure bottles are kept tightly capped, unless they are being heated.

A NEAT LAB IS A SAFER LAB

* Do not leave used pipet tips, pipettes, Kim wipes, paper towels, eppendorf tubes, sharps, slides and other waste on your bench. Clean up after yourself. * Do not leave unneeded samples such as petri dishes, test tubes, slides, scintillation vials, and eppendorf tubes in incubators, refrigerators, or on the bench. Discard samples as soon as you are finished with them.

PROTECT YOURSELF

* Keep hoods closed when not in use. Do not raise the hood sash above the safe level indicated by the line on the yellow sticker. Always work in the hood, not on the edge of the hood. * Wear protective gear such as safety glasses, lab coats, gloves, and face shields as instructed by the teaching staff. If you have a latex allergy, vinyl gloves are available.

Scientific Method, Graphic and General biology

The independent variable is the variable that is intentionally changed in the experiment, such as the temperature of the water in which an effervescent tablet was dissolved.
 the levels of the independent variable are the different values of the independent variable, such as using water at 10°, 20°, 30°, 40°, and 50° C. The levels of the independent variable can also be thought of as the experimental groups that are set up.

 the dependent variable is the variable that responds to the changes in the independent variable. For example, the time it takes for the tablets to dissolve in the different temperatures of water is the dependent variable.

 the control is the standard against which the researcher compares the results from each treatment group (level) in the experiment. For example, the control might be the room temperature water, which is about 20° C. In many cases, there will not be a true control. The researcher could then set one of the groups as the standard and measure the other groups against that standard.

 the repeated trials are the number of times the experiment is repeated to determine how the independent variable affected the results. For example, if the researcher tried dissolving the tablet seven different times in each temperature of water, he/she would have seven repeated trials. If 10 different
