Plants Are On The Move! A Study of Gravitropism

Science Fair Project Idea

Scientific Method

As we humans zip from place to place, we often forget to stop and smell the roses. Compared to our fast-paced lifestyle, plants seem rooted to the spot. Don't be deceived by appearances however, plants are on the move! This experiment will investigate the stimulus/response relationship in plants and prove that plants can move up and down in response to gravity. Read more

Runoff and Fertilizer Use

Science Fair Project Idea

Scientific Method

Many people routinely use fertilizer for crops, gardens, and lawns. What people don't know is that each time they apply fertilizer, the fertilizer seeps through the soil into the water table. This can eventually lead to the contamination of a local water source, like a stream, pond, lake, bay, or ocean. This is an especially big problem for agricultural practices that frequently use large amounts of fertilizer on fields that are connected by irrigation channels. The run-off of fertilizer… Read more

Spinning Your Wheels: Pinwheel Sensitivity

Science Fair Project Idea

Scientific Method

So you've just heard the "Happy Birthday" song and now it's time to blow out the candles. If you are sitting far away from the candles, you know you'll have to blow harder to get them all out than if you were sitting closer. In this science fair project, you'll blow on different kinds of pinwheels with a blow-dryer and see how far away you can get before they stop spinning. This will give you clues about how sensitive the pinwheels are to wind, and why. So come spin your wheels and get… Read more

The Power of Your Eyes: How Vision Affects Balance

Science Fair Project Idea

Scientific Method

Staying balanced might feel simple, but there’s so much more involved than you would think! The way your body balances is actually the result of several body systems working together. Your muscles and joints provide feedback (proprioception) about where your body is in space, your inner ear senses movement and position, and your eyes give you important visual cues about your surroundings. Vision is especially important because it helps your brain judge where you are in relation to the… Read more

How Can Your Faucet Save Water?

Science Fair Project Idea

Scientific Method

One way to save water is to turn the faucet off while you brush your teeth. But did you know that there are products that can help save water even while the water is on? In this experiment find out how low-flow faucets and aerators work to reduce the flow of water. How much water can you save? Read more

Top Crops: Finding Hidden Grasses and Beans in Processed Foods

Science Fair Project Idea

Scientific Method

It's the bottom of the ninth, and you've spent a great afternoon at the ball game with a hotdog, a soda, and an ice cream in hand, but I'll bet you're not thinking about how many crops went into those classic baseball snacks. Sure, the bun contains wheat, but did you know that the hotdog might contain wheat, too? And soybeans may have been used to give that ice cream its perfectly smooth texture, while corn was likely used to sweeten the entire meal! Crops can be changed and added to processed… Read more

Bits, Bytes, and Bases: Write a JavaScript Binary/Decimal/Hexadecimal Converter

Science Fair Project Idea

Scientific Method

This is a challenging first computer science project. You'll learn the basics of how digital devices can represent numbers using only 0's and 1's, and you'll write a JavaScript program to convert numbers between binary, decimal and hexadecimal notation. Read more

How Tweet It Is: Bird Songs in Classical Music

Science Fair Project Idea

Scientific Method

Do you enjoy singing contests like American Idol? Well, male songbirds have their own version of a singing competition that has been going on for thousands of years, and classical musical composers have been taking notes! In this music science fair project, you'll investigate the different instruments composers have used to imitate or create impressions of bird songs and bird calls. Read more

How Far Can Sparks Jump?

Science Fair Project Idea

Scientific Method

Piezoelectric barbecue fire starters work by creating a spark that ignites the volatile lighter fluid, which then starts the charcoal burning. They are low current, high voltage devices. How high does the voltage have to get to make a spark in air? This project shows you a way to find out by with an inexpensive experimental setup to measure the distance that the spark can travel between two spherical electrodes. Read more

Deforestation

Science Fair Project Idea

Scientific Method

The conversion of forested to unforested areas has been occurring since humans began to impact and change their environments during the agricultural revolution. Recently deforestation has become a global problem, particularly for developing industrial countries and countries with very large populations. You can use satellite mapping resources to investigate the connection between urbanization, population growth and deforestation. You can also investigate the connection between deforestation… Read more
