A Box Office Disappointment: Why the Book is Always Better than the Movie

Science Fair Project Idea

Scientific Method

The author of this project hypothesized that movies often disappoint readers because book-based movies tend to "dumb down" the works on which they are based (Fuhrman, 2002). Naturally, selective compression is necessary when telling a story as a movie, or no one would sit through it. (Hey, maybe there's an idea for a different experiment!) Selective compression is not necessarily the same, however, as simplification. There are ways to objectively measure the complexity of written language with… Read more

A Ground-Breaking Revelation: Testing Longitudinal Waves in Different Soil Types

Science Fair Project Idea

Scientific Method

Did you know that waves travel through the Earth's crust all the time? One major source of these waves is earthquakes, although ground motion can also be caused by something man-made, such as a mine blast or nuclear explosion, or other natural events, such as landslides or volcanic activity. How does an earthquake cause these waves? The entire outer shell of the Earth, known as the lithosphere, is made up of tectonic plates that are constantly moving. There are seven or eight large… Read more

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

A Prescription for Success: Drugs & Your Genetics

Science Fair Project Idea

Scientific Method

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 just a single… Read more
