Investigate the Vitamin C Level in Bell Peppers During Various Stages of Ripeness

Science Fair Project Idea

Scientific Method

Vitamin C is a water-soluble vitamin that has many functions in the body. Vitamin C is needed to bolster the immune system. It is an antioxidant that protects LDL cholesterol from oxidative damage, and it is needed to make collagen, a substance that strengthens many parts of the body, such as muscles and blood vessels. Our bodies do not make vitamin C, so we must get it from dietary sources. Citrus fruits, carrots, avocados, and spinach all have vitamin C. Bell peppers, like the ones shown in… Read more

High-Speed Magnets: Exploring Faraday's Law and Lenz's Law

Science Fair Project Idea

Scientific Method

Safety Notes about Neodymium Magnets: Neodymium magnets are very strong. Adult supervision is recommended when using them. Be careful not to drop the magnets, and do not let them slam together or fall. They may pinch your fingers, crack, or shatter. Keep magnets away from small children, pets, credit cards, and pacemakers. In the Science Buddies project Human-Powered Energy, you can learn about the basics of magnetic induction, or how moving magnets can be used to generate an… Read more

Build a Radio-Controlled (RC) Robot

Science Fair Project Idea

Engineering Design Process

Radio-controlled (RC) robots can explore places that are difficult or dangerous for humans to get to, like collapsed buildings after a natural disaster. They can use cameras and a variety of other sensors to gather information about their environment, like the presence of toxic gases or other hazardous materials. The robots can even use grippers and robotic arms to collect and safely dispose of some materials. You can build your own RC robot using the Science Buddies Bluebot kit, Electronics… Read more

Chain Reaction: Inversion and the Pappus Chain Theorem

Science Fair Project Idea

Scientific Method

Here is a challenging problem for anyone with an interest in geometry. This project requires background research to solve it, but it is an excellent illustration of visual thinking in mathematics. Figure 1 below shows a series of circles (iC₁, iC₂, iC₃, ..., iC₃₀), inscribed inside an arbelos. What is an arbelos? The arbelos is the white region in the figure, bounded by three semicircles. The diameters of the three semicircles are all on the same line segment, AC,… Read more

Build a Solar-Tracking Robot

Science Fair Project Idea

Scientific Method

Light sensors are part of many devices that we use every day. For example, they help your phone know when to automatically brighten or dim the screen based on ambient light levels. They can also be used to help solar panels track the sun, which helps the panels generate more power. Many spacecraft and planetary rovers are solar-powered. In this project you will build and program your own solar-tracking robot. Optionally, you can add solar panels and rechargeable batteries. Can your robot keep… Read more

Biodiesels: Converting Oil into Clean Fuel

Science Fair Project Idea

Scientific Method

Most of the energy and fuel that we use in the United States is derived from burning fossil fuels. Fossil fuels are the remains of plants and animals that lived hundreds of millions of years ago. Examples of fossil fuels include coal, petroleum oil, and natural gas. Burning coal releases 21.3 gigatons of carbon dioxide— a greenhouse gas that may be responsible for global warming and climate change—into the air in one year. About half of this amount is absorbed by natural processes… Read more

Hurricanes and Climate

Science Fair Project Idea

Scientific Method

The past few years have histories of extremely powerful and dangerous storms. Storms have also become more numerous over the last few years. To investigate potential effects of climate on hurricane number and strength, in this project you will study the effects of El Niño on hurricanes. The goal of this project is to study the historic relationship between the El Niño/Southern Oscillation (ENSO) and the number and strength of hurricanes, either in the Atlantic or Pacific Oceans. Since… Read more

The Tree of Life – II (advanced)

Science Fair Project Idea

Scientific Method

Imagine that a biologist arrived at your big family reunion and had no idea who were sisters, cousins, aunts, uncles, etc., but tried to sort it out by how all of you look. Just based on how you look, would s/he be able to guess whether the kid standing next to you is your sister or your cousin? The biologist might be able to make some good guesses this way, but by using samples of your family's DNA, s/he could construct your whole family tree. In this project, you'll use Web-based computer… Read more

Locating an Earthquake Using a Global Seismic Network

Science Fair Project Idea

Scientific Method

When an earthquake happens, how are scientists able to determine the original location of the quake? In this project, you'll use archived data from a global network of seismometers to find out for yourself. You will make your own seismograms using the Global Earthquake Explorer program, and then use the seismograms to determine the location of earthquake epicenters. Read more

Expression Cloning

Science Fair Project Idea

Scientific Method

What is expression cloning and how is it used in the biotechnology industry? How are plasmids constructed for use in a bacterial expression system? You can investigate these questions and more using bacterial expression kits meant for high school classes. You will need a laboratory space equipped to grow bacteria and carry out simple molecular biology. A kit with plasmids and bacterial cells to transform are also needed. Here are two possibilities: BioBuilder What a Colorful World Kit … Read more
