How do drones automatically balance themselves when you let go of the controls? Find out in this project as you build and program an experimental setup to make a drone automatically control its tilt angle about a single axis. See this page for a complete list of our mini drone projects. You may wish to do the projects in order. Read more

Back and Forth to Go Forward: A Snake on Wheels?

Science Fair Project Idea

Scientific Method

Have you ever ridden on a Roller Racer® or PlasmaCar®? These are ride-on toys that you move ahead by moving the steering mechanism back and forth. You've probably seen skateboarders "slaloming" on level ground to keep rolling, it's basically the same idea. This project explores the physics behind this method of locomotion. Read more

Bacteria Transformation

Lesson Plan Grade: 9th-12th

Students construct paper recombinant plasmids to simulate the methods genetic engineers use to create modified bacteria. They learn what role enzymes, DNA and genes play in the modification of organisms. For the particular model they work on, they isolate a mammal insulin gene and combine it with a bacteria's gene sequence (plasmid DNA) for production of the protein insulin.Engineering Connection Bacteria are the most common organisms modified by genetic engineers due to… Read more

NGSS Performance Expectations:

HS-LS1-1. Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.

Bacterial Resistant Materials and the Best Disinfectant

Science Fair Project Idea

Scientific Method

If you'd rate yourself high on the bacteriophobia scale, just keep on scrolling down to the next project. Bacteria are all around us, and normally our body's defenses keep us blissfully unaware of them. If you don't mind finding out where they're lurking in your house, then you might find this project interesting. Read more

Barometric Pressure and Weather

Science Fair Project Idea

Scientific Method

How does temperature change as barometric pressure changes? You can make a device to test this using a barometer and a thermometer on your stovetop. You can collect your own weather data from a barometer and thermometer over a period of a week or month. You can also use data from a weather station to plot the relationship between barometric pressure and temperature. Does the pressure change as humidity changes? Measure the pressure in a humid and non-humid environment (like your bathroom… Read more

Bat Detector: Listen to the Secret Sounds of Bats

Science Fair Project Idea

Scientific Method

Do you have bats in your neighborhood? Have you heard them "whoosh" by you, but not been able to see them? In this science fair project, you will be able to detect flying bats by listening in on the ultrasonic signals they produce to locate objects in their environment. The bat detector is a useful and fun tool for studying the biology of this nocturnal flying mammal. Read more

Beats

Science Fair Project Idea

Scientific Method

Beats are a pattern of oscillating sound intensity (i.e., the volume of the pattern grows and fades with a regular cycle). They occur when two tones of almost equal frequency interfere. People can perceive beat frequencies below about 7 Hz. Figure out how to create sound files to play pure tones on your computer. Create files with a pure tone of one frequency in the left channel, and a pure tone of a different frequency in the right channel. Systematically explore different frequency… Read more

Biodiversity Survey

Science Fair Project Idea

Scientific Method

Survey your area to find out which species of plants and animals live there. You might be surprised to find out that something you grew up thinking was very common, is actually quite unique! For example, if you live in the great plains, then you may think that prairie dogs are a nuisance or a pest. Actually, some species of prairie dogs are only found here, and have a very important role for short and tall grass prairie ecosystems. The prairie dogs are an important part of the food-chain, and… Read more

Bio-Engineering: Making and Testing Model Proteins

Lesson Plan Grade: 9th-12th

Students act as if they are biological engineers following the steps of the engineering design process to design and create protein models to replace the defective proteins in a child's body. Jumping off from a basic understanding of DNA and its transcription and translation processes, students learn about the many different proteins types and what happens if protein mutations occur. Then they focus on structural, transport and defense proteins during three challenges… Read more

NGSS Performance Expectations:

HS-LS1-1. Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.
HS-LS1-2. Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
HS-ETS1-2. Design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.
HS-ETS1-3. Evaluate a solution to a complex real-world problem based on prioritized criteria and trade-offs that account for a range of constraints, including cost, safety, reliability, and aesthetics, as well as possible social, cultural, and environmental impacts.

Bits, Bytes, and Bases: Write a JavaScript Binary/Decimal/Hexadecimal Converter

Science Fair Project Idea

Scientific Method

This is a challenging first computer science project. You'll learn the basics of how digital devices can represent numbers using only 0's and 1's, and you'll write a JavaScript program to convert numbers between binary, decimal and hexadecimal notation. Read more
