Project Idea
Antibiotics work by destabilizing the metabolism or cellular structure of bacteria, preventing growth, and causing bacteria to die. Some strains of bacteria have mutated and found a way to resist the actions of antibiotics. These are called resistant strains because they resist the actions of available antibiotic treatments. There are many different types of antibiotics that are continually being developed to combat new strains of resistant bacteria. Some antibiotics work better on different… Read more

Project Idea
What do pneumonia, ear infections and strep throat have in common? When they are caused by bacteria (instead of viruses) they are treated by antibiotics. That sounds simple enough, right? You have probably had antibiotics several times in your life. You go to the doctor because you feel lousy, if he or she determines you have a bacterial infection you get a prescription for antibiotics, and within the first day or so you often start feeling much better. Unfortunately, there is a large… Read more

Project Idea
Most of the energy and fuel that we use in the United States is derived from burning fossil fuels. Fossil fuels are the remains of plants and animals that lived hundreds of millions of years ago. Examples of fossil fuels include coal, petroleum oil, and natural gas. Burning coal releases 21.3 gigatons of carbon dioxide— a greenhouse gas that may be responsible for global warming and climate change—into the air in one year. About half of this amount is absorbed by natural processes… Read more

Project Idea
In this cooking and food science fair project, you will explore the role of proteins as emulsifying agents. Emulsifying agents are substances that are soluble in both fat and water and enable fat to be uniformly dispersed in water as an emulsion. Foods that consist of such emulsions include butter, margarine, salad dressings, mayonnaise, and ice cream. Emulsifying agents are also used in baking to aid the smooth incorporation of fat into the dough and to keep the baked goods tender. Natural… Read more

Project Idea
Animals respond to chemical cues in different ways. If an animal turns away from a chemical cue, then that chemical is a repellent. If an animal turns toward a chemical cue, then that chemical is an attractant. Attractants and repellents can be airborne chemicals, chemicals found in food, or chemicals that diffuse through water. One example of an airborne chemical is a pheromone, a chemical signal that is released by one individual to attract another. Moths release pheromones to attract… Read more

Predict how tall you can build a tower using only two sheets of newspaper as building material. You can't use tape, glue, staples, or anything else, just two sheets of newspaper. You can tear, bend, cut, or fold the newspaper. Try it out and see how close you can come to your prediction. Can you beat your prediction? As you're building, you may come up with ideas to make a better tower. Try them out! (It's not like the materials are expensive!) Here are some variations you might want to… Read more

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… Read more

Ahchoo! Got that stuffy nose and I-can't-breathe kind of cold? Those sniffles and clogged sinuses are bad enough, but why does it also seem everything tastes so bland and flavorless when we are sick? Is there really truth to the idea that smell is a key part of taste? Gather up a few volunteers, hit the kitchen, and try this experiment to find out. Read more

Soil may look like a bunch of dirt, but good quality soil is actually a complex mixture of dirt, nutrients, microorganisms, insects and worms. What type of benefit do these microorganisms offer a growing plant? You can test this by baking soil in the oven to sterilize and kill the microorganisms. Do plants grown in sterile soil do better than plants in unsterilized soil? What about adding worms to one plant, but not to the other. Will the plant with worms grow better? Some insects are bad… Read more
