Abstract

Disinfectants are products that kill harmful bacteria that inhabit surfaces. Disinfectants can be in household and personal cleaning products. Which products work best? Compare different household cleaning products, like bleach or Lysol, to see which ones kill the most bacteria. Compare different brands of antibacterial hand soap or dish soap to see which brand is the most effective. How do hand sanitizers work? Compare rub-on hand sanitizers to see if they work better than alcohol, or compare to old fashioned soap and water (Pittis, 2000).

Microbiologist

Microorganisms (bacteria, viruses, algae, and fungi) are the most common life-forms on Earth. They help us digest nutrients; make foods like yogurt, bread, and olives; and create antibiotics. Some microbes also cause diseases. Microbiologists study the growth, structure, development, and general characteristics of microorganisms to promote health, industry, and a basic understanding of cellular functions. Read more

Industrial Health & Safety Engineer

Think of all the jobs in the world that involve machinery, chemicals, toxins, radiation, loud noise, or travel to places above or below Earth's surface—all of these jobs carry an element of risk to the workers. Industrial health and safety engineers work to minimize this risk. They inspect work sites and help workers and companies understand and comply with safety laws. They use their knowledge of mechanical processes, chemistry, and human psychology and performance to anticipate hazardous conditions. Protecting workers requires excellent communication skills and a strong sense of responsibility. Read more

What do the sequencing of the human genome, the annual production of millions of units of life-saving vaccines, and the creation of new drought-tolerant rice varieties have in common? They were all accomplished through the hard work of biological technicians. Scientists may come up with the overarching plans, but the day-to-day labor behind biotechnology advances is often the work of skilled biological technicians. Read more
