Keeping You in Suspens(ion)

Science Fair Project Idea

Scientific Method

Suspension bridges, with their tall towers, long spans, and gracefully curving cables, are beautiful examples of the work of civil engineers. How do the cables and towers carry the load that is on the bridge? Can a suspension bridge carry a greater load than a simple beam bridge? This science project shows you how to find out. Read more

Molecular Scissors

Science Fair Project Idea

Scientific Method

Ever used a pair of molecular scissors? Restriction enzymes are molecular scissors that cut DNA into pieces. Find out which enzymes will cut, and where by making a restriction map. Then you can figure out what will happen if you change the sequence of the DNA. Will the same enzymes still cut the new DNA sequence? Read more

How Salty Does the Sea Have to Be for an Egg to Float?

Science Fair Project Idea

Scientific Method

Some objects float on top of the ocean, and other objects sink to the bottom. Why? Try this eggsperiment to find out! Read more

What Conflicting Mental Tasks Reveal About Thinking: The Stroop Effect

Science Fair Project Idea

Scientific Method

Can you pat your head with one hand while you rub your stomach with the other? This science project idea is kind of like doing that, but this project can actually give you some insight into how your mind works. The task is to name colors. It sounds simple enough, but see what happens when color words get in the way. Read more

Can Biodegradable Hydrogels Help Conserve Water in Farming?

Science Fair Project Idea

Scientific Method

Growing crops takes a huge amount of water. That same water is also needed for drinking, bathing, and other industries. In dry climates or lands experiencing drought, there is a big push to conserve (save) water as much as possible. In this project you will experiment with creating environmentally friendly jelly-like materials called hydrogels and see if they can help soil retain water thus reducing the amount of water needed to grow crops.

Design Your Own Slime

Science Fair Project Idea

Engineering Design Process

There are many different kinds of slime out there. Some slime is runny and liquid-like; other slime is thick and rubbery. Some slime glows in the dark, some is fluffy, and some is even magnetic! What set of properties makes the best slime? What kind of slime would you choose to make if you were selling slime as a toy in your own "slime shop"? In this project, you will experiment with different slime recipes and try to perfect one to make the best slime. Read more

Make Your Own pH Paper

Science Fair Project Idea

Scientific Method

This is a simple "kitchen chemistry" project about acid/base chemistry. Scientists measure the acidity or alkalinity of a solution using a logarithmic scale called the pH scale. In this project you'll learn about the pH scale, and you'll make your own pH indicator paper using a pH-sensitive dye that you'll extract from red cabbage. You can use your pH paper to measure the acidity/alkalinity of various household solutions. Read more

The Dynamics of a Bouncing Ball

Science Fair Project Idea

Scientific Method

Many sports use a ball in some way or another. We throw them, dribble them, hit them, kick them, and they always bounce back! What makes a ball so bouncy? In this experiment you can investigate the effect of air pressure on ball bouncing. Read more

Make Yogurt Spheres Using Molecular Gastronomy

Science Fair Project Idea

Scientific Method

Imagine if instead of spooning up a bowl of soup, a container of yogurt, or a cup of pudding you could just pick up and pop in your mouth a round, mess-free, ball-like blob of one of those. It might feel like snacking rather than eating a meal! In this food science project you can try exactly that. The simple step-by-step directions will lead you through trying a fun cooking technique called reverse spherification to turn yogurt into semi-solid balls, which are called "raviolis." How do you… Read more

Can Cell Phones Survive a Drop Test?

Science Fair Project Idea

Engineering Design Process

Why do so many people use cell phone cases? Do cell phones really need the extra protection, or is it just because cases look fancy? In this engineering science project, you will test the durability of calculators instead of cell phones, find out if cases increase the durability of the device, and build some of your own cases that do!
