Science Fair Project Idea
thumbnail 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
Have you ever known someone who had a bad reaction to a prescription drug? Although pharmaceutical companies test new drugs on a large number of people to make sure the drug works the way it is supposed to, often a small percentage of people respond differently to the drug. A person's genetics plays a large role in determining his or her response to a given drug. Our genes are made up of hundreds to millions of nucleotides of DNA (deoxyribonucleic acid), the genetic code. If… Read more

DNA is the "instruction manual" for the successful growth of a living thing, from a single cell to a mature adult. When the DNA of an organism is somehow damaged, it can have an impact on the organism's development over time. In this plant science fair project, you will track how irradiation (exposure to radiation) of radish seeds affects germination (sprouting of a seedling from a seed). Read more

Science Fair Project Idea
thumbnail Believe it or not, scientists were recently able to recover tissue from a 68-million-year-old Tyrannosaurus rex fossil! Not only were they able to purify non-mineralized tissue, but they also succeeded in obtaining partial sequence information for protein molecules in the T. rex tissue. In this genomics science fair project, you will use the T. rex's protein sequence to search sequence databases for the its closest living relatives. Read more

Science Fair Project Idea
thumbnail 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
Many proteins act as catalysts which speed up or regulate a biochemical reaction. The kinetics of an enzyme can be investigated by measuring the reactants and products of the reaction over time. Research the enzymatic reaction of a protein and investigate its kinetics. Measure the production of hydrogen peroxide (H2O2) by catalase, the digestion of gelatin by papain, or any other enzymatic reaction you have access to. Bio-Rad's provides a great measurement platform for exploring… Read more

Science Fair Project Idea
thumbnail Have you ever had to sort a jumble of objects into piles, based on their type? Maybe laundry, or a big load of dishes, or while organizing the garage or a closet? Scientists have to do something similar when they want to study or isolate just a single type of protein. For example, a botanist might discover an exotic plant that is poisonous when eaten, but that also has great antibiotic properties. To help develop a new antibiotic for human use, he or she would have to separate the different… Read more

Time Required Average (6-10 days)
Prerequisites Familiarity with how to use a micropipette is needed.
Material Availability This science fair project requires specialty items, including the Bio-Rad [# Link Name="BioChem_p035.5" Value="HtmlAnchor" #] and a sample of green fluorescent protein. See the Materials and Equipment list for details. It also requires a number of common molecular biology items, such as pipettes, micropipettes and tips, and a UV light—likely obtainable from your school laboratory.
Cost Very High (over $150)
Safety Adult supervision is recommended. Follow all safety instructions that come with the Bio-Rad kit(s).
Science Fair Project Idea
thumbnail Our genes are made up of hundreds to millions of building blocks, called DNA nucleotides, and if just a single nucleotide of DNA becomes mutated it might cause a devastating genetic disease. But sometimes a mutation actually does no damage. What kinds of mutations have to occur to cause a genetic disease? In this science project, you will explore online genetic databases to identify how a mutation in a gene can result in a dysfunctional protein, and how other mutations may have no… Read more
