Measuring Height Or Distances with a Camera

Science Fair Project Idea

Scientific Method

If you know or calculate the field of view for your camera, you can use it to measure distances and the height of almost anything. It's all a matter of basic trigonometry. Read more

Minimizing Bacteria in the Thawing and Cooking of Meat

Science Fair Project Idea

Scientific Method

How does your family thaw and cook meat? Have you ever wondered if it is the safest way? In this practical science project, you can find out and shed light on safe practices in the kitchen by investigating how many viable bacteria are present in samples of meat that have been thawed or cooked using different methods.

Students are challenged to use computer-aided design (CAD) software to create "complete" 3D-printed molecule models that take into consideration bond angles and lone-pair positioning. To begin, they explore two interactive digital simulations: "build a molecule" and "molecule shapes." This aids them in comparing and contrasting existing molecular modeling approaches—ball-and-stick, space-filling, and valence shell electron pair repulsion (VSEPR)—so as to… Read more

NGSS Performance Expectations:

HS-PS1-1. Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

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

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

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

Programming NANORGs in a Virtual World

Science Fair Project Idea

Scientific Method

Imagine yourself as a software engineer, a decade and a half from now. You are called upon to help solve the world energy crisis by programming nano-organisms (NANORGs) to extract energy from industrial sludge. Your program must be small enough to fit in the NANORGs' tiny processors, yet at the same time meet several challenges. First and foremost, your NANORGs need to navigate on their own, extract energy from the sludge, and find collection points to deliver the harvested energy. Second,… Read more

Purification Strategies

Science Fair Project Idea

Scientific Method

In order to study individual biochemical compounds like proteins, DNA, or RNA, biochemists need to know how to purify these components from a complex mixture. This is especially important for biotechnology and pharmaceutical industries, which sell purified biochemicals as reagents or drugs to consumers. Do an experiment to purify DNA, RNA, or protein from a complex mixture (for purifying DNA, see the Science Buddies project Extracting Onion DNA). The source of the material can be a cell… Read more

Recycling PLA Plastic using Green Chemistry

Lesson Plan Grade: 9th-12th

Educational Goal To understand: How polylactic acid (PLA) plastic is an example of green chemistry technology particularly pollution prevention and designing safer chemicals Student Objectives Students will: Learn about renewable "corn" plastic is made from polylactic acid Recycle the polylactic acid cup into a new product: a cleaning solution Conduct a saponification reaction Analyze PLA against the 12 principles of green chemistry (Optional) Verify the contents of their… Read more
