A Magnetic Primer Designer

Science Fair Project Idea

Scientific Method

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

Molecular Scissors

Science Fair Project Idea

Scientific Method

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

Are You Left or Right Sided?

Science Fair Project Idea

Scientific Method

Did you know that our brains are split into two parts, right inside our head? One half is the left brain and the other half is the right brain. Some people use one half of the brain more than the other half when they are doing certain activities, like talking or reading. The half that is used is sometimes tied to which hand they prefer to use. If someone likes to use their right hand when doing an activity, like drawing or throwing a ball, do they also prefer to use their right ear, eye, or… Read more

Can Exercise Really Make Our Brains Work Better?

Science Fair Project Idea

Scientific Method

"Use it or lose it!" Sure, we all know physical exercise is important to keeping our bodies fit. But how important is physical exercise to your brain? In other words, is there any connection between an active body and increased brain power? This is an easy project where you can test the effect of exercise on a critical brain function: memory.

Iron-Rich Foods: How to Get the Most Out of Them

Science Fair Project Idea

Scientific Method

Did you know that your body needs a certain amount of iron in order to stay healthy? Iron can be found in much of what you consume each day. Almond flour—frequently used in cookies—is just one example of an iron-rich food. However, only a small fraction of the iron in food gets absorbed by the body, partially because the body can only absorb dissolved iron. In this project, you will study whether the acidic environment in your stomach helps dissolve iron. You will use a color-based… Read more

Does a Cell Phone Conversation Affect Reaction Time?

Science Fair Project Idea

Scientific Method

Does talking on a cell phone make one a more dangerous driver? Here is an experiment you can do to investigate whether reaction time is adversely affected by a simultaneous phone conversation. Read more

A Juicy Project: Extracting Apple Juice with Pectinase

Science Fair Project Idea

Scientific Method

Do you know why enzymes are oftentimes called the workhorses of biochemistry? It's because they can speed up a wide variety of chemical reactions, and chemists and biologists use enzymes to do all kinds of jobs. In this project, pectinase, an enzyme frequently used in the food industry, will be used to extract juice from apples. Read more

Pedigree Analysis: A Family Tree of Traits

Science Fair Project Idea

Scientific Method

Some characteristics, like the shape of your hairline or whether your earlobes are attached or detached, are inherited from your parents. In this science project you will see how writing these characteristics onto a family tree can help you determine how they are inherited Read more

Can Video Games Be a Form of Exercise?

Science Fair Project Idea

Scientific Method

Have you ever played a video game that made you break a sweat? Or pant a little bit? The majority of video games are sedentary, meaning done in one position, but there is an increasing trend toward video games where the players are physically active. Do you think these video games can be considered exercise? This science fair project will help you find out! Read more

Air Particles and Air Quality

Science Fair Project Idea

Scientific Method

What does the phrase, "Like a breath of fresh air," mean to you? This common phrase can have different meanings: calming, relaxing, invigorating, energizing or CLEAN! After all, you never hear anyone say, "Like a breath of dirty air," do you? Find out how clean the air is in this simple experiment. Read more
