What Materials Can Block a Wi-Fi Signal?

Science Fair Project Idea

Scientific Method

Have you ever suffered from poor Wi-Fi reception for your smartphone, tablet, or laptop? Certain materials can actually block a Wi-Fi signal; do you think that could be part of your problem? In this science project, you will do an experiment to find out which materials cause the biggest drop in signal strength from a wireless router. Read more

Give Yourself a Lift: Lightening the Load with Pulleys

Science Fair Project Idea

Scientific Method

Before the Industrial Age, people relied on muscle power for moving and lifting heavy objects. Here's a project that shows you how you can use your head to make heavy lifting easier on your muscles–and your back! Read more

Gigantic, Invisible Triangles: Measuring Height (or Altitude) with an Inclinometer

Science Fair Project Idea

Scientific Method

If you've ever wondered how tall that bridge is, or how high your kite was, then this could be a good project for you. You'll learn how you can use the mathematics of right triangles to measure the height of an object with two measurements that you can make on the ground. Read more

Archimedes Squeeze: At What Diameter Does an Aluminum Boat Sink?

Science Fair Project Idea

Scientific Method

Where do you get your best ideas? At school with your friends? When you are out for a bike ride? Over 2,200 years ago, a scientist named Archimedes got one of his best ideas when he sat down in his bath. Eureka! He went running through the streets without even bothering with his clothes. What was he so excited about? He had discovered that when objects, like his body, are placed in water, water is pushed out of the way. Have you noticed that, too? The weight of the water that is pushed out of… Read more

Solid Ground? Measuring Soil Bearing Capacity

Science Fair Project Idea

Scientific Method

Foundations for many types of structures rest on soil. This project shows how you can investigate the bearing capacity of different types of soil. Read more

It's Hard Work to Work Harden! Learn How to Make Metals Stronger

Science Fair Project Idea

Scientific Method

It's easy to forget that metals are everywhere and in nearly everything. They are a part of our lives in so many ways that we hardly notice them. But just stop and think about it. We use metal spoons to eat and cook our food. Cars, bikes, and planes are composed of metals. Metals are in our furniture and part of your school supplies. Some people even have metal in the dental work in their mouths. Their strength and dependence is obviously very important. But what are metals? In this science… Read more

The Physics of Artificial Gravity

Science Fair Project Idea

Scientific Method

How can we make space stations with artificial gravity a reality? In this science project, you will explore the physics of creating artificial gravity with circular motion. Read more

Diaper Science: How Hydrogels Absorb Water

Science Fair Project Idea

Scientific Method

Many disposable diapers contain a polymer, called sodium acrylate, which is useful for absorbing water. Do background research to learn about sodium acrylate, and how it reacts with water. Make sure that you understand the terms hydrophilic, polarity, hydrogel and hydrogen bonding. Cut out the middle, padded section of a disposable diaper. Cut this into equally-sized square pieces, approximately 10-12 cm on a side. Remove some of the stuffing material so that you can staple the open… Read more

Solar-powered Chemistry: Study Chemical Reaction Rates in Ultraviolet Beads

Science Fair Project Idea

Scientific Method

Most of the ultraviolet (UV) light produced by the Sun is blocked by the atmosphere, but some UV light does still reach Earth. It can be detected using electronic devices, but can also be detected with something called UV beads. UV beads contain a pigment that changes color when they are exposed to ultraviolet radiation from the Sun. In this chemistry science fair project, you will use UV beads to study how temperature affects the rate at which they lose their color. Read more

The Leaning Tower of Pasta

Science Fair Project Idea

Scientific Method

Here's a project for a budding architect or structural engineer. Can you make a strong, lightweight tower using only uncooked spaghetti and white glue? In this project, you'll learn about materials testing and apply what you learn to building and testing structures that are both strong and light. Read more
