Science Fair Project Idea
thumbnail Native plants are important for both ecological and medicinal reasons. However, most native plants are not very well studied. One way to know more about these plants is to understand which other species of plants they are most closely related to. In this science project you will sequence part of the chloroplast genome from a native plant and use this information to determine its evolutionary relationship to other species of plants. If the plant you chose has not been sequenced before, you can… Read more

Prerequisites High school biology class; familiarity with using the PCR machine and gel electrophoresis equipment, and/or using the equipment with a mentor.
Material Availability You will need specialized pieces of equipment, including a PCR machine (thermocycler) and a gel electrophoresis apparatus. If your school does not have this equipment you might want to seek out a mentor at a junior college, university, or biotechnology company. If you have the resources you can do the DNA sequencing yourself, otherwise you can send the samples to Dr. Baysdorfer at California State University, East Bay, see Experimental Procedure for more details.

thumbnail It has been said that, "Life is like a box of chocolates—you never know what you're going to get" (Forrest Gump in Forrest Gump, 1994). In this science project you can test the "Forrest Gump Chaos Theory" by using M&M's®, which are much cheaper than a box of chocolates. What if life is more like a bag of M&M's? Find out in this science project if some things in life are predictable by using the awesome power of statistics. Read more

thumbnail Do you know someone who has an autoimmune disease? Autoimmune diseases are fairly common, affecting more than 23.5 million people in the United States, which is about 1 in 13 people! You may have heard of some of them, such as diabetes (type 1), rheumatoid arthritis, and celiac disease. Many autoimmune diseases are poorly understood, but they all have one thing in common: they happen because a person's immune system (which normally fights off germs to keep the person healthy) attacks the… Read more

thumbnail In the wild there are two types of animals: the hunters and the hunted. A good predator is always on the prowl for fresh prey. What can an animal do to stay off of the menu? To survive, some animals use camouflage so they can better blend in with their surroundings. In this science project, you will be the hungry predator hunting for M&M® prey. But it may not be as easy as it sounds — some of your prey will be camouflaged by their habitat. Will they be able to avoid your grasp? … Read more

thumbnail Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items that are blue in color have the same dye, called FD&C blue 1. In this chemistry science fair project, you will build a simple colorimeter, a device that measures the concentration of colored chemicals in solutions. You will use the colorimeter to measure the concentration of blue dye #1 in sports drinks, and to track the rate at which the… Read more
