Science Fair Project Idea

Engineering Design Process

LivingLoom looks at how plants can take an active role in making textiles instead of just being used as raw materials. By spinning microgreen seeds into biodegradable yarns, the textiles can actually sprout and grow over time. The project opens up new ways to think about sustainable, care-based design, and invites us to rethink how we connect with plant life through the things we make and use. Read more

Build an Automatic Dog (or Cat) Treat Dispenser

Science Fair Project Idea

Engineering Design Process

Does your dog get bored when you are not home? Do you ever toss them a few treats right before you head out the door? What if you could keep them busy by automatically dispensing treats throughout the day? What about training them to sit in a certain place or even press a button by automatically rewarding them with treats? In this project you will build your own automatic dog (or cat, or other pet) treat dispenser that you can customize to react to different sensors. Read more

How Antacids Relieve Heartburn

Science Fair Project Idea

Scientific Method

Have you ever experienced heartburn after eating a large, greasy meal? Or have you heard of someone complaining about heartburn pains? It's very common; over 60 million people in the U.S. have heartburn at least once every month. Heartburn pain usually results from stomach acids escaping from the stomach and irritating the esophagus above it. Luckily, there are medical drugs, called antacids, which can help relieve heartburn pain. But how do antacids work, and how effective are they? In this… Read more

Crime Scene Chemistry: Determine the Identity of an Unknown Chemical Substance

Science Fair Project Idea

Scientific Method

Picture this situation: An elderly woman is rushed to the hospital complaining of severe abdominal pain, tinnitus, and lethargy. Suspecting a drug interaction, the emergency room doctor starts questioning her. The doctor learns that the woman takes no medicines except aspirin for her arthritis. Since she cannot swallow pills well she takes a powdered form of aspirin which she buys in bulk and keeps in a plastic container in her kitchen next to her baking goods. She had just finished a day of… Read more

Pedigree Analysis: A Family Tree of Traits

Science Fair Project Idea

Scientific Method

Some characteristics, like the shape of your hairline or whether your earlobes are attached or detached, are inherited from your parents. In this science project you will see how writing these characteristics onto a family tree can help you determine how they are inherited Read more

Balancing Act: Finding Your Center of Gravity

Science Fair Project Idea

Scientific Method

Like to have the balance of a tightrope walker? Try the more close–to–the–ground balancing test in this easy experiment to learn a few trade secrets of the high wire experts. In this project, you'll find your center of gravity and explore the physics of balance at the same time. No net required for this balancing act! Read more

Huddle & Cuddle: How Puppies Keep Warm

Science Fair Project Idea

Scientific Method

What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss. Read more

Which Liquid Works Best for Evaporative Cooling?

Science Fair Project Idea

Scientific Method

When we get hot, we sweat. Sweating helps cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes using what are referred to as swamp coolers. In some cases, these coolers may be more energy-efficient than traditional air conditioners. In this chemistry science fair project, you will find out which liquid works best for evaporative cooling.

Guitar Jingle: Discovering the Locations of Harmonics

Science Fair Project Idea

Scientific Method

Did you know that your guitar has a secret? Yes, that's right—hidden along each string are special places where you can play harmonics and make your guitar sound like a bell! In this music science fair project, you'll find out where the main harmonics are located on a guitar, and then see how those locations are related to the length of the strings. So get out your guitar—it's time to ring in a science fair project! Read more

Shed Light on Electric Generators: Do More Coils Generate More Electricity?

Science Fair Project Idea

Scientific Method

The electricity in your home probably comes from a power plant, but did you know that you can actually generate your own electricity? Wondering what it would take to light up a small light? This is your chance! In this electronics science project, you will build your own electric generator and investigate how to light up not just one, but two lights. Read more
