Biowarfare: Experiment with Viruses that Destroy Bacteria

Science Fair Project Idea

Scientific Method

Most people are not aware that the soil around them is a battle scene. The combatants are very small—bacteria on one side and bacteriophage on the other. The bacteriophage (or phage for short) try to pierce the outer coats of the bacteria and inject them with phage DNA. If successful, the DNA will take over the inner machinery of the bacterial cells and force them to make many copies of the phage. After the copies are made, the bacterial cells break apart, releasing new phage that start… Read more

Developing Images with X-rays

Science Fair Project Idea

Scientific Method

You have probably had X-rays taken at the dentist's or doctor's office, but do you know how the X-ray images are made? Images made using X-rays, also called radiographs, are considered to be relatively safe to take, even though they are made using a small amount of radiation, specifically electromagnetic radiation. Radiation is energy that travels through space as either waves or high speed particles. Watch this video to learn more about electromagnetic radiation and X-rays. X-rays can travel… Read more

Investigate the Vitamin C Level in Bell Peppers During Various Stages of Ripeness

Science Fair Project Idea

Scientific Method

Vitamin C is a water-soluble vitamin that has many functions in the body. Vitamin C is needed to bolster the immune system. It is an antioxidant that protects LDL cholesterol from oxidative damage, and it is needed to make collagen, a substance that strengthens many parts of the body, such as muscles and blood vessels. Our bodies do not make vitamin C, so we must get it from dietary sources. Citrus fruits, carrots, avocados, and spinach all have vitamin C. Bell peppers, like the ones shown in… Read more

Protein Structure and Function

Science Fair Project Idea

Scientific Method

How a biological system functions is a consequence of the 3-D structures of biological macromolecules like proteins and protein complexes. Proteins can be categorized into different protein families based upon sequence, structure, and function. Typically, proteins in the same family have similar biochemical functions. You can investigate the structure of a protein by using protein databases (Entrez Protein, SwissProt, PDB) and 3-D computational models. You can compare the structures of… Read more

Is the Gold in My Jewelry Real?

Science Fair Project Idea

Scientific Method

Have you ever wondered if a piece of jewelry is real gold or if it's just some ordinary metal alloy? It turns out that some metals have a unique property; even in small amounts, they can be toxic to some organisms, including algae, molds, fungi, and bacteria, although it often takes many hours to see an effect. Can this phenomena, called the oligodynamic effect be used to tell whether or not the gold or silver in a piece of jewelry is real? Do bacteria react differently to pure, plated, and… Read more

The Tree of Life — I (basic)

Science Fair Project Idea

Scientific Method

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether the kid standing next to you is your sister or your cousin? The biologist might be able to make some good guesses this way, but by using samples of your family's DNA, s/he could construct your whole family tree. In this project, you'll use a Web-based… Read more

Minimizing Bacteria in the Thawing and Cooking of Meat

Science Fair Project Idea

Scientific Method

How does your family thaw and cook meat? Have you ever wondered if it is the safest way? In this practical science project, you can find out and shed light on safe practices in the kitchen by investigating how many viable bacteria are present in samples of meat that have been thawed or cooked using different methods.

Trace Your Ancient Ancestry Through DNA

Science Fair Project Idea

Scientific Method

Did you ever wonder about your ancient ancestors? Who they were? Where they came from? In this science project, you will investigate the secrets of your distant past as revealed by your DNA. In order to obtain a sample for DNA analysis, you will scrape a soft swab inside your mouth to collect cheek cells. The cheek cell sample will be sent to a lab for processing, and the results of the analysis will be sent to you. Based on the genetic markers in your DNA, the ancient clan that your… Read more

Calling It Quits: What Is the Most Effective Way to Quit Smoking?

Science Fair Project Idea

Scientific Method

Maybe you know someone who smokes, and you want to help them to quit. They've probably already told you how hard it is to stop once a person has started smoking. This project tries to answer the question: What is the most effective way to stop smoking? Read more

Cinnamon Gum and Mouth Microbes

Science Fair Project Idea

Scientific Method

Did you know that a scientific study has shown that chewing Big Red Gum reduces mouth microbes? (ScienceDaily contributors, 2004) The cinnamon oil in the gum is a natural defense against mouth bacteria that cause tooth decay and bad breath. Conduct an experiment to compare products with cinnamon essence in gum, candy, toothpaste, and mouthwash to see if they can decrease mouth germs. Do a before and after swab of the mouth with a Q-tip. Which treatments work the best? Can you find another… Read more
