Science Fair Project Idea
Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map. Then you can figure out what will happen if you change the sequence of the DNA. Will the same enzymes still cut the new DNA sequence? Read more

Science Fair Project Idea
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

Time Required Long (2-4 weeks)
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.
Cost High ($100 - $150)
Safety This project uses ethidium bromide, which is a carcinogen. Always wear gloves and safety goggles when handling. Dispose of the ethidium bromide according to your school or institute's hazardous waste protocols. If you have concerns, ask your teacher or mentor for advice.

Science Fair Project Idea
Imagine that you want to create your own brand of colored candies. You know they would be a success if only you could figure out how to make a certain color, such as purple. How can you do this when government regulators have approved just a few food dyes? First, you will need to find out how your competitors make all of their colors from these few dyes. Do different candy brands use the same or different dyes? This can be figured out with gel electrophoresis, a technique commonly used in… Read more

Science Fair Project Idea
Woolly mammoths shook the ground of ice-age tundras for millennia, living next to saber tooth tigers and prehistoric man. Although they have been extinct for thousands of years, scientists continue to learn more and more about this mighty animal. Some of the most exciting new research is being produced by looking at DNA extracted from the hair and bones of woolly mammoths entombed in ice. In this genomics science fair project, you will use bioinformatics tools to determine the woolly mammoth's… Read more

Science Fair Project Idea
The first land animals took their tentative steps out of the ocean and onto solid ground around 365 million years ago. Over millions of years, these early ancestors developed into tetrapods, including amphibians, reptiles, dinosaurs, birds, and mammals. Then, around 50 million years ago, the reverse process occurred: the mammalian ancestor of today's whales returned to the ocean. In this genomics science fair project, you will use mitochondrial protein sequencing to trace the evolution of… Read more

How do scientists "copy" DNA? They use a process called the Polymerase Chain Reaction, or PCR. The key to making this process work is having a short piece of DNA, called a primer, that will stick to the larger piece of DNA you want to copy, called a template. In this science project, you will test how the number of matches and mismatches in a primer will affect its ability to stick, or anneal, to the DNA template during PCR. Read more

Extinct might be a word you associate with animals that lived long ago, like the dinosaurs, but did you know that over 18,000 species are classified as "threatened" (susceptible to extinction) today? Scientists involved in wildlife conservation have a tough job; they're in charge of determining what needs to be done to prevent a species from becoming extinct. Habitat, food supply, and impacts of local human populations are just a few of the factors these scientists take into account. It's a lot… Read more
