Yogurt, biofuel, biodegradable plastics, and antibiotics are all examples of products based on biotechnology research and manufacturing techniques. What else will we be able to create as we use biotechnology in new ways? You can explore some of these techniques for yourself with projects from our biotechnology techniques science and engineering project list.

Science Fair Project Idea
In this project, you'll learn how to isolate DNA from onion cells, separating it from other cellular components in a manner that still preserves its structure and sequence. In the end, you'll have enough DNA to see with the unaided eye, and you'll be able to spool it to demonstrate its strand-like structure. Read more

Enzymes speed up chemical reactions by factors of at least a million. Now that's acceleration! This project investigates how temperature affects how fast these enzymatic reactions occur. Read more

Have you ever heard or read about GMO? GMO stands for genetically modified organisms. Scientists can deliberately modify the DNA of organisms, such as bacteria or plants, to change their properties for a specific purpose. For example, crops can be modified to become more drought- or pest-resistant. Genetic engineering is a very powerful tool in biotechnology that has already found many different applications in agriculture, medicine, and industry. In this project, you will engineer a… Read more

Imagine seeing waves glowing a beautiful blue color. The marine dinoflagellate Pyrocystis lunula is responsible for this magnificent phenomenon. Pyrocystis lunula is a bioluminescent organism—bioluminescence is the production of light by living organisms. But does this organism always glow, no matter what the conditions, such as how much light there is? In this biotechnology science fair project, you will investigate how altering this dinoflagellate's exposure to light and dark affects… Read more

What color is grape soda? If you pour it into a clear glass you can easily see it is purple, but that is usually not its natural color. Manufacturers add red and blue dye to the soda. The dyes mix together and you get purple soda. What if you wanted to un-mix the dyes, could you? Yes! In a chemistry laboratory, using a technique called column chromatography, you could separate the two dyes again. But what about at home, can you use low-tech supplies to do the same thing? In this science… Read more

When biologists want to separate different pieces of DNA, RNA, or proteins they use a technique called gel electrophoresis. In this science project you'll build a gel electrophoresis chamber and use it to discover how many components are in different colors of food coloring dye. Read more

Can you imagine a glowing loaf of bread? You might not be able to make the whole loaf glow, but you can get baker's yeast to fluoresce! The way to do this is to modify the genetic information of the yeast organism. The technology that is used to do this is called genetic engineering. With genetic engineering, you can insert a fluorescent protein gene from a jellyfish into yeast cells, so they start glowing under blue light! Do this project to see for yourself! Read more

Are biofuels the wave of the future? People often talk about these plant-derived fuels as a way to someday cut down on our dependency on non-renewable carbon-based fuels, like gasoline. Ethanol (a type of alcohol) is a common biofuel used today. In the United States, ethanol is a common biofuel additive to normal gasoline. In fact, some states mandate that when you fill up your gas tank, 10 percent of the total fuel volume be made of ethanol. Brazil, the world's largest user of ethanol-based… Read more

Have you ever gone to pour yourself a cup of milk and all you get is milk clumps? What happened to the milk is called coagulation, which is the mechanism that occurs when proteins in the milk clump together. While you do not necessarily want this in your milk, without coagulation (or curdling), there would not be any cheese or yogurt, which is why it is a very important process in the food industry. But what makes milk curdle? In this science project you will use pineapple juice to curdle milk… Read more

Many scientists are currently very excited about CRISPR, as it has the potential to revolutionize gene editing. But what exactly is CRISPR and what does it do? CRISPR is a novel tool in gene editing that allows the modification of genetic DNA at specific target sites in many different organisms. Researchers have high hopes that this technology can, one day, cure genetic diseases, as mutated DNA sequences can easily be corrected. In this project, you will use CRISPR to mutate a DNA sequence… Read more
