Extracting Heat Energy from a Compost Pile

Science Fair Project Idea

Scientific Method

Earth, the Sun, wind, and water are all sources of renewable and sustainable energy—and sources you probably already know about. But did you know that you can get energy from such things as banana peels, coffee grounds, and newspaper? In a process called composting, you can transform kitchen and other solid wastes into a product that is beneficial for your garden: homemade fertilizer. As the waste decomposes, it also creates heat. Can this naturally created heat be put to use? In this… Read more

PID Controller Tuning for a Drone

Science Fair Project Idea

Engineering Design Process

Note: to do this project you will need the DIY Mini Drone Kit, available from our partner Home Science Tools®. An Arduino must be purchased separately. The Electronics Kit for Arduino, available from our partner Home Science Tools®, contains the additional parts you will need, including an ultrasonic sensor. The program in the DIY Mini Drone: Arduino™ Altitude Control project uses a proportional controller to control the drone's altitude. A potentiometer is connected to one… Read more

A Matter of Time

Science Fair Project Idea

Scientific Method

Do you wake up at the crack of dawn, or do you need an alarm clock to wake you up each morning? It may surprise you that the two are not always in synch. Nowadays, we use Standard Time to set our watches instead of Solar Time. Which method of timekeeping is the most accurate? Get ready to synchronize your watches! Timekeeping is the science of how to keep time with precision and accuracy. People have been finding ways of measuring time for thousands of years, usually based on the movements… Read more

Explore Interplanetary Spacecraft Maneuvers with FreeFlyer®

Science Fair Project Idea

Scientific Method

If you are interested in space travel and willing to do some coding, this project is for you! It uses FreeFlyer®—powerful software that allows you to simulate space travel—to explore essential mission questions. Space travel is complex. Many factors influence the trajectory of a spacecraft. Simulations like the ones generated by FreeFlyer are powerful, as they allow you to analyze each factor in isolation, and then visualize the effects in various ways. Once you familiarize… Read more

Invasive Species

Science Fair Project Idea

Scientific Method

Invasive species are organisms (either plant or animal) that have been introduced into a new, non-native area and spread rapidly in the new environment due to a lack of regulation by predators. Frequently, invasive species will out-compete native species for resources which can put native species at risk. This is an especially big problem for threatened habitat and endangered species, which are already at risk. Survey your area to document cases of invasive species invading a local… Read more

Foldit: Playing a Game While Solving Protein Structures

Science Fair Project Idea

Scientific Method

Unlocking the three-dimensional structure of a protein is crucial to help scientists understand how it functions in our bodies and how it can cause devastating diseases if it becomes disrupted or interacts in the wrong way. However, figuring out the structure of a protein in three-dimensional space can be very challenging. Proteins are the functional units of our cells, and every protein is made up of a long chain of amino acids. Amino acids come in different shapes and sizes, and they have… Read more

How Do Baseball Stadium Dimensions Affect Batting Statistics?

Science Fair Project Idea

Scientific Method

Have you ever wondered how playing in a certain stadium affects how well the athletes perform? Major League Baseball (MLB) is played in ballparks that have their own individual quirks when it comes to the exact layout of the field. How an individual ballpark affects player performance, which is known as ballpark effects, is heavily investigated in the field of baseball. To name just a few parks and their different traits, Fenway Park (the long-time home ballpark for the Boston Red Sox in… Read more

Build Your Own Dobsonian Telescope

Science Fair Project Idea

Scientific Method

For an advanced science fair project, you can build your own telescope and learn how to use it to make observations of the night sky. Can you make your own observations to determine the orbital period of Jupiter's major moons? The Dobsonian telescope, first built and popularized by astronomer John Dobson, is considered to be the best bang-for-your-buck if you want to build a good amateur telescope. The smaller the telescope's aperture the less expensive to build, but also the less… Read more

Build an Arduino Robot

Science Fair Project Idea

Engineering Design Process

The Science Buddies Bluebot Kit contains parts to build four different robots: A motion-activated robot that uses a passive infrared (PIR) sensor A light-tracking robot that uses photoresistors A line-following robot that uses infrared emitter-detectors An obstacle-avoiding robot that uses bump sensors However, in each project, the sensors are hard-wired to control the robot's motors. This allows the robot to steer left and right based on input from two sensors, but it does not allow the… Read more

Sounds Like RFID: Using a Radio Frequency Identification (RFID) Reader to Make Musical Instruments

Science Fair Project Idea

Scientific Method

Passports, identification cards, bus passes, and even some credit cards contain RFID tags. An RFID (radio-frequency identification) tag allows a card to be read by a computer from a short distance away. While this is very useful in everyday life, would you believe you can make music with it? RFID + sampled music sounds + a little crafting = a fun musical instrument that is limited only by your imagination. In this science project, you will make handbells out of paper cups that play real sounds,… Read more
