A Cool Way to Make Electricity: Solar Cell Power Output vs. Temperature

Science Fair Project Idea

Scientific Method

Solar cells provide a clean way of making electricity directly from sunlight. In this project you will build a simple circuit and experimental setup to investigate whether the power output of a solar cell changes with ambient temperature. Read more

What Modern Microbes Could Survive on Early Earth?

Science Fair Project Idea

Scientific Method

Have you ever wondered how life began on Earth? Or how life could get started on other planets? To help us better understand how life began, many scientists try to figure out what it would have been like to live on early Earth. In this science project, you will try to grow microscopic life that could have survived some of the harsh conditions of early Earth! Read more

Tricks for Treats: How Long Does It Take to Train Your Pet?

Science Fair Project Idea

Scientific Method

Have you ever been to an animal show and seen a sea lion balance a ball on his nose, or a tiger jump through a hoop? Or maybe you've met dogs who can sit, fetch, shake, or beg on command. The range of tricks that you can teach animals is amazing, but how does animal training work, and how long does it take? Find out in this trick-and-treat filled science fair project! Read more

Comparing Different Types of Irrigation Systems

Science Fair Project Idea

Scientific Method

With heat waves impacting the world globally, many gardeners, farmers, and scientists are turning to passive irrigation systems that reduce fossil fuel emissions while keeping plants well-watered and alive in the sweltering heat. In this science experiment, you will compare and contrast the effectiveness of passive irrigation systems compared to traditional surface irrigation systems and their impact on overall plant growth.

Can You Hear Sounds in Outer Space?

Science Fair Project Idea

Scientific Method

Have you ever wondered what sounds you can hear in space? The answer is simple: none! In outer space there is utter silence. There are no sounds of traffic jams or thunderstorms or crashing waves. No buzzing bees or babies crying. Just silence. In this experiment, you will discover why empty space is void of sound and prove it with the help of the microphone in your phone and a sensor app. Read more

Football Field Goals: Going the Distance

Science Fair Project Idea

Scientific Method

When watching a football game, have you ever wondered why some kicks lead to a successful field goal and others do not? There are a lot of variables at play in a game of football, and many of them are related to physics. One variable that can affect whether a field goal is successful is distance. In this science project, you will explore how field goal success rate is affected by distance from the goalposts. What will be the best distance for you to kick some field goals? Grab a football, head… Read more

Building Personal Medicine Apps to Help Patients

Science Fair Project Idea

Engineering Design Process

Remembering to take medication or perform a test regularly, consistently, and at specific times can be difficult for elderly people with short-term memory loss, or teenagers absorbed in activities. With mobile devices becoming our constant companions, could a smartphone or tablet offer a solution? The Massachusetts Institute of Technology (MIT) has created a simple tool making it possible for anyone who has a computer and Internet access to create a reminder app. It is easy, quick, and… Read more

Smelly Science: A Sniff Test

Science Fair Project Idea

Scientific Method

Take a deep breath: freshly baked cookies, smoke from a wood fire, or a rose—your nose is an amazing smell detector! Your sense of smell can not only identify a huge variety of odors, but it is also incredibly sensitive. Think about how easily you can detect if someone in your neighborhood has a barbecue just by smelling the hints of smoke from the grill far away. How strong or weak you perceive an odor depends on its concentration. What do you think is the lowest concentration of a… Read more

Use a Catapult to Storm Castle Walls

Science Fair Project Idea

Scientific Method

You may have seen movies or read books where armies in medieval times catapulted large rocks or other objects at castles (or each other!). These armies used different types of catapults to accomplish different goals — for example, launching things over or into castle walls to knock them down. In this experiment, you will use a ping-pong ball catapult to lay siege to a "castle" and find the right settings to hit your targets. Read more
