Science Fair Project Idea

Scientific Method

When you go to the beach, you may not know if the beach is natural or man-made. The popularity of sandy beaches prompted developers in the past to bring in sand to cover rocky shorelines and turn them into more popular sandy beaches. However, the actions of the tides, currents and waves carried the extra sand out into the reef, endangering the reef and the creatures living on it. You can use a water table to conduct experiments with sand movements and reefs. How is sand moved by water? How… Read more

SeaPerch: An Underwater Robot

Science Fair Project Idea

Engineering Design Process

Underwater robots, or remotely operated vehicles (ROVs), help us explore areas of the ocean that can be dangerous for humans. They can provide valuable scientific information about deep-sea life and ocean climate. However, you do not need access to the ocean to build and test your own ROV. If you have ever wanted to build your own ROV but were not sure where to start, the SeaPerch platform is a great option. You can purchase a complete kit with all the required parts and follow the detailed… Read more

Seasonal Disease Outbreaks

Science Fair Project Idea

Scientific Method

"Flu season" is something we deal with every winter. Cyclical or seasonal outbreaks of an infectious disease can occur for a variety of reasons, such as seasonal changes in host behavior (for example, more people staying indoors), the seasonal abundance of disease carriers (for example, mosquitos), and many others. Another factor that can play a role in cyclical outbreaks occurs when the natural immunity to a disease has a short duration. This enables each individual in the population to… Read more

Shaping Your Thoughts?

Science Fair Project Idea

Scientific Method

This is an interesting experiment that explores certain aspects of how your brain pays attention. In this project, you'll have to recruit a bunch of volunteers to take a simple test: naming a list of printed shapes. What makes the test tricky is that words will be printed on top of the shapes. The word/shape combination creates the potential for the brain to get conflicting information. Which information is more likely to grab your attention: the shape you are supposed to name or the word just… Read more

Similar Triangles: Using Parallax to Measure Distance

Science Fair Project Idea

Scientific Method

Want to stretch your imagination? One good way is to try to imagine how far it is to a distant star. How much farther away is it than the moon is from the earth? How much farther away than the earth is from the sun? How long would it take to get there? In this project, you'll learn one way of measuring the distance without leaving Earth. Read more

Slippery Slopes and Sticking Surfaces: Explore the Forces of Friction

Science Fair Project Idea

Scientific Method

Whoopee! No matter what age, who doesn't like flying down the slides at parks and pools? In this experiment, you might be surprised what you can learn about the fascinating forces of friction while sliding down (or sticking to) those fun, slippery slopes. Caution: only speed demons need apply for this activity. Read more

Smart Medicine Cabinet: Build a Sensor That Reminds Patients When to Take Medication

Science Fair Project Idea

Scientific Method

Have you ever had to take prescription medicine to get over an illness? To get better, it is important to take the medication in the proper manner and at the proper time. Wouldn't it be cool if there were a tool or piece of automated equipment that held your medicine and reminded you to take it? A tool that would know when you picked up the bottle and took your medicine? Building a smart medicine cabinet is what this science project is all about! Read more

Smarter Farming with Aerial Photo Analysis

Science Fair Project Idea

Scientific Method

Wondering what sustainable, high-producing agriculture might look like? This science project explores how analyzing bird's-eye-view pictures of a field can make farmers aware of variations in their fields. Farmers can use this information to optimize their farming practices, or even feed this information to high-tech agricultural equipment so the machines can automatically adjust their actions (like fertilizing or watering) to the needs of a piece of land.

Soil and Earthquakes

Science Fair Project Idea

Scientific Method

Is soil structure an important factor in earthquake dynamics? Investigate soil liquefaction and how different soil types respond to earthquake movements. Are movements more dramatic in sandy/loamy or clay type soils? Which soil structures are most stable? Which are the most volatile? (MCEER, 2005) Read more

Sound Localization

Science Fair Project Idea

Scientific Method

How accurately can people identify the location of a sound source when blindfolded? Imagine the hemisphere of space that extends above your shoulders at arm's length. Divide that hemisphere up into regular sectors and test the ability of blindfolded test subjects to point to a remembered sound source. For example, you could use the beep from a timer held at each test location, and then have the test subject point to where they think the timer was located. Record the magnitude and direction of… Read more
