Home Sweet Biome: How Do Plants Grow in Different Environments?

Science Fair Project Idea

Scientific Method

Have you ever looked around and noticed the plants and animals that grow in your neighborhood? Have you ever visited friends in another part of your city, state, or even another part of the country? Have you noticed whether the plants and animals where they live are similar to those growing near you? What would it be like to live where they do? Why do certain plants and animals grow in one area, but not in another? In this science fair project you will learn about biomes and how different… Read more

How Are Antibodies Used for Blood Typing?

Science Fair Project Idea

Scientific Method

Have you ever heard about different blood types? Do you know what your blood type is? Antibodies help scientists determine different human blood types. This project is a practical introduction to the human immune system in which you will learn about what antibodies are, how they are formed, and how they can be used to identify different types of cells.

Have you ever wondered how many different types of animals live around your home, like in your backyard or a local park? Animals come in all shapes and sizes, each a small part of the amazing diversity of life. These differences can help people use systems to classify animals into different groups. One way people classify animals is by their phylum. Do you know which phylum you belong to? In this science activity, you will investigate the diversity (or biodiversity) of the animal life around… Read more

How Can Tofu Pack Such a Flavorful Punch?

Science Fair Project Idea

Scientific Method

Spicy fried tofu. It's a delicious and savory main dish at many Asian restaurants. Stab a golden-brown piece, bite into it, and the juice inside rushes out, filling your mouth with rich flavors. Continue eating and you find the texture is very chewy and meat-like. Did you ever wonder how those white blocks of tofu you see in grocery stores are transformed into the chewy little sponges packed with flavorful juices you see in Asian restaurants? Try this cooking and food science fair project to… Read more

How Do Baseball Stadium Dimensions Affect Batting Statistics?

Science Fair Project Idea

Scientific Method

Have you ever wondered how playing in a certain stadium affects how well the athletes perform? Major League Baseball (MLB) is played in ballparks that have their own individual quirks when it comes to the exact layout of the field. How an individual ballpark affects player performance, which is known as ballpark effects, is heavily investigated in the field of baseball. To name just a few parks and their different traits, Fenway Park (the long-time home ballpark for the Boston Red Sox in… Read more

How Do Cats Respond to Bird Sound Recordings?

Science Fair Project Idea

Scientific Method

Cats are great house pets, but as every cat observer knows, they are also instinctive hunters. This experiment provides an interesting way to learn about cat behavior. You'll play bird call recordings for pet cats, and watch to see if the cat pays attention to the sound (by turning towards it) or ignores it. Will a pet cat distinguish between the calls of local birds vs. non-local birds? Read more

How Do the Seasons Change in Each Hemisphere?

Science Fair Project Idea

Scientific Method

On a rainy day, do you ever wonder what the weather is like on the other side of the planet? Different regions around the globe can have very different seasonal weather patterns. In this experiment, you can test if these seasonal variations are related to which hemisphere each region is located in. Read more

How Do You Get Heat from a Supercooled Solution? Explore the Chemistry Within Hand Warmers

Science Fair Project Idea

Scientific Method

You're at the high school football game and it's getting pretty chilly as the sun goes down. You're determined to keep cheering for your team, but your hands are freezing—have you ever tried hand warmers? The chemistry within these little packets is pretty cool. Hand warmers provide a unique and fun way to study the chemistry of crystal formation and heat generation. By pressing a button in a pouch, which contains a supercooled solution, you start a rapid exothermic (heat-producing)… Read more

How Do You Know Where You Are Without GPS? Dead Reckoning and Inertial Navigation

Science Fair Project Idea

Engineering Design Process

Put a meter stick on the ground. Starting at one end of the stick, close your eyes and try to walk exactly one meter. Open your eyes. How close were you? Now try it again with five, ten, or twenty meters. Does it get harder as the distance gets bigger? Without an outside reference from your visual system, it's quite difficult to know exactly how far you've gone! Electronic navigation systems face the same problem. Without an external reference like the global positioning system (GPS), it's very… Read more
