Science Fair Project Idea

Scientific Method

We encounter an amazing array of colors every day, from the greens of plants and the many colors of their flowers, to the pinkish blue of a sunset, to the artificial coloring in beverages. How do we perceive all of these colors? When light hits an object, some of that light is absorbed by the object, and the light that is not absorbed is what we see. In this science project, you will build a simple spectrophotometer from a cell phone and use it to investigate how visible light is absorbed by… Read more

Make a Biohybrid Robot

Science Fair Project Idea

Engineering Design Process

When you think of robots, you might think of things made out of plastic or metal...but what about living materials? Living materials have one big advantage: they can heal and repair themselves if they get damaged. Since it might not always be easy to repair a damaged robot (for example, a robot on another planet), some scientists want to figure out how to include living, or biological, materials in them to create "biohybrid" robots. In this project, you will create your own simple biohybrid… Read more

A Matter of Time

Science Fair Project Idea

Scientific Method

Do you wake up at the crack of dawn, or do you need an alarm clock to wake you up each morning? It may surprise you that the two are not always in synch. Nowadays, we use Standard Time to set our watches instead of Solar Time. Which method of timekeeping is the most accurate? Get ready to synchronize your watches! Timekeeping is the science of how to keep time with precision and accuracy. People have been finding ways of measuring time for thousands of years, usually based on the movements… Read more

Analyzing Impact Craters on Mercury

Science Fair Project Idea

Scientific Method

Have you ever wanted to analyze data from a NASA spacecraft? In this science project you will use data from NASA's MESSENGER mission to measure the diameter and calculate the depth of impact craters on Mercury. You will then analyze that data for relationships between a crater's depth and diameter. This is your chance to perform a science project as a NASA researcher would! Read more

Biodegradable Plastics

Science Fair Project Idea

Scientific Method

Plastics are made of polymers, chemical structures containing many repeated subunits. How does the polymer type of a plastic affect the biodegradability of the plastic? Do research on how plastic is made and what types of polymers are used for making different plastics. Can you learn to make your own plastic? What materials can you use for making plastic that is biodegradable? Test biodegradability by burying plastic samples for different lengths of time. (Kadar, 2004) Reducing solid waste and… Read more

BLAST into the Past to Identify T. Rex's Closest Living Relative

Science Fair Project Idea

Scientific Method

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

Hacking the Air Gap: Stealing Data from a Computer that isn't Connected to the Internet

Science Fair Project Idea

Scientific Method

You might think that one sure-fire way to keep your computer safe from hackers is to disconnect it from the internet entirely. But did you know that even without internet, a computer can transmit data using light, sound, vibrations, or even heat? In this project, you will investigate how a spy or hacker can steal data from an "air-gapped" computer that has no internet connection. You can even use a smartphone equipped with a sensor app to demonstrate how the data can be picked up by a nearby… Read more

Aerodynamics and Bridge Design

Science Fair Project Idea

Scientific Method

Research the famous collapse of the Tacoma Narrows suspension bridge. What lessons were learned about the potentially damaging effects of wind on bridges? What structures stabilize a bridge against wind forces? Build models and use a wind tunnel to test your hypothesis. Read more

Monitor Your Plants with a Soil Moisture Sensor

Science Fair Project Idea

Scientific Method

Do you or your family have a lawn, garden, or potted plants that you water regularly? Irrigation—or the artificial application of water to plants and landscaping—accounts for over two-thirds of the world's freshwater consumption (U.S. Geological Survey, 2016)! While that total includes farms, in the United States landscape irrigation still accounts for almost one-third of residential water use. As much as half of that water is wasted due to inefficient watering methods (WaterSense,… Read more

Football Punting: Distance vs. Hang-time

Science Fair Project Idea

Scientific Method

When the punter is trying to hit the "coffin corner" (within the opposing team's 10-yard line), out of bounds, what is the best angle to kick the ball for correct distance and maximum "hang time?" (For more information on the physics involved, see: Gay, 2004, Chapters 4 and 5.) Read more
