Science Fair Project Idea

Scientific Method

Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much. Read more

Protein Structure and Function

Science Fair Project Idea

Scientific Method

How a biological system functions is a consequence of the 3-D structures of biological macromolecules like proteins and protein complexes. Proteins can be categorized into different protein families based upon sequence, structure, and function. Typically, proteins in the same family have similar biochemical functions. You can investigate the structure of a protein by using protein databases (Entrez Protein, SwissProt, PDB) and 3-D computational models. You can compare the structures of… Read more

Keep Your Arduino Robot From Falling Off a Cliff

Science Fair Project Idea

Engineering Design Process

Humans cannot see infrared light, but robots can! At least, they can when they use special infrared light sensors. These sensors can help robots detect nearby objects to avoid collisions and even help them avoid driving off edges. In this project you will build your own Arduino robot that uses infrared sensors to avoid driving off the edge of a table. Read more

Wind Turbine Efficiency

Science Fair Project Idea

Scientific Method

Try different wind turbine/propeller (chord length, pitch) designs by making models from balsa wood. Connect the spinning axle to a DC motor and measure the voltage produced across a resistor to measure power output. Use fan as wind source. (Judge, 2004) Read more

Avoiding Disaster: The Right Bridge Design

Science Fair Project Idea

Scientific Method

A bridge collapse, like that of the I-35W Mississippi River Bridge, can be a major disaster. Bridges that cannot hold enough weight to do their intended job can be a serious public safety issue. And if they collapse, they can also cause economic damage due to costly rebuilding and people and companies scrambling to figure out how to circumvent the months of traffic impacts. Figure 1. On August 1, 2007 the I-35W Mississippi River Bridge collapsed killing 13… Read more

Disinfectants

Science Fair Project Idea

Scientific Method

Disinfectants are products that kill harmful bacteria that inhabit surfaces. Disinfectants can be in household and personal cleaning products. Which products work best? Compare different household cleaning products, like bleach or Lysol, to see which ones kill the most bacteria. Compare different brands of antibacterial hand soap or dish soap to see which brand is the most effective. How do hand sanitizers work? Compare rub-on hand sanitizers to see if they work better than alcohol, or compare… Read more

Genetically Engineer Yeast to be Fluorescent

Science Fair Project Idea

Scientific Method

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

Does Chemical Lightening Affect the Structure of Human Hair?

Science Fair Project Idea

Scientific Method

Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Can a human hair hygrometer also detect changes in hair structure caused by chemical lightening? This project shows you how to find out. Read more

What's the Fastest Way to Solve Rubik's Cube?

Science Fair Project Idea

Scientific Method

If you like solving challenging puzzles, this could be a good project for you. In this project you will research different methods for solving a Rubik's cube, and then do an experiment to compare them to each other. Which method works fastest? Read more

Germination

Science Fair Project Idea

Scientific Method

Germination is the process by which a seed emerges from the seed coat. Many different variables can effect the process of germination. Try to sprout seeds from different species of plant to see if different species vary in germination time. Are weeds faster germinators than vegetables? Try measuring seeds and then germinating them to see if big seeds sprout at a different rate than small seeds. Try sprouting seeds in different environments to test the effect of different environmental… Read more
