Nanotechnology in Action: Organic Electronics

Lesson Plan Grade: 9th-12th

This activity focuses on the use of graphene in organic fibers, and their applications in organic electronics, e-textiles and wearable technologies. Students learn about the properties of graphene—unique form of carbon—and how graphene-based fibers are fabricated, how to measure resistance, how to calculate resistivity, and how a material changes its electrical properties. Students also learn about the importance of defining design parameters, which is an… Read more

Only If They Think They Can Get Away with It?

Science Fair Project Idea

Scientific Method

How many times have you seen a car without the appropriate permit (either a license plate or placard that hangs from the rearview mirror) parked in an accessible parking space reserved for people with disabilities? If you find this behavior upsetting, you might be interested in figuring out how to discourage "cheaters" who use these spaces to make a quick trip into the store. Is it enough to let them know someone might be watching? Read more

Have you ever spent time spinning a hula hoop around your waist or arm? Could you easily do it, or was it difficult? Have you ever wondered how hula hoops work, or, in other words, what makes them be able to spin around a person's waist or arm? It comes down to the physics that is involved. Physics can help you determine what makes one hula hoop a winner and another a flop. In this activity you will get to create your own hula hoops and investigate how their masses affect how they spin. … Read more

Picture This: How Visualizing Data Can Lead to the Right (or Wrong) Conclusion

Science Fair Project Idea

Scientific Method

Big data is one of the most promising and hyped trends in technology and business today. Big data refers to data-analysis jobs that are too large and complex to be analyzed by applications that are traditionally used. Big data sets hold valuable information. Many publicly available data sets have the potential to improve our everyday lives by giving us insight into the things we care about. How well-equipped are we to extract information from the data? Visualizations and aggregations (or… Read more

Pitch Perception

Science Fair Project Idea

Scientific Method

Do violin students have better relative pitch than piano students? Since the violin requires the player to choose the correct location to stop the string in order to sound the proper note, you might think that violin players would, as a result of practice, have better ear training than piano students. On the other hand, you could argue the opposite viewpoint, since piano students would have the benefit of hearing correct intervals (assuming that the piano is in tune). Which hypothesis do you… Read more

Pluck Out & Pick New String Materials for Your Guitar

Science Fair Project Idea

Scientific Method

Walk into any music store and you'll find a dizzying array of string choices for your classical guitar, including rectified nylon, clear nylon, carbon fluoride, bronze wound, phosphor bronze wound, silver-plated copper wire, Polytetra-flouro-ethylene (PTFE), each in a range of tensions from low to high. There is no single best brand or best material. All have their advantages and disadvantages. A set of strings that sounds "sparkling" on one guitar might sound dull on another, primarily because… Read more

Porosity

Science Fair Project Idea

Scientific Method

Soils are made of particles of different types and sizes. The space between particles is called pore space. Pore space determines the amount of water that a given volume of soil can hold. Porosity is the percentage of the total volume of soil that consists of pore space. Compare the porosity of different types of soil. Which types of soil hold the most water? Can you see this under a microscope? Read more

Practice

Science Fair Project Idea

Scientific Method

We've all heard that "practice makes perfect," but what is the best way to practice? For example, does "mental practice" do any good? You'll need at least 9 volunteers for this project. Pick a well-defined sports activity, with a measurable outcome, such as shooting basketball free-throws (measure number of shots taken and number of shots made), or balancing on one foot on a slightly raised beam (measure how long you can do it; if it's too easy, try closing your eyes). Test all volunteers… Read more

Preventing SQL Injection Attacks

Science Fair Project Idea

Engineering Design Process

How many websites do you have accounts with that store personal information like your name, email, phone number, or mailing address? If the people running these websites are not careful, hackers could gain unauthorized access to, and even change or delete, your information. They can do this using something called SQL injection, which involves entering malicious code into text fields on a website. In this project you will learn how SQL injection works and figure out how to prevent it. Read more
