Have you ever had to take antibiotics? Your doctor probably told you to finish taking all the pills even if you felt better after one or two days. But why is that? Why shouldn't you stop taking antibiotics as soon as you feel better? You might be surprised to hear that if you do, you might contribute to the creation of antibiotic resistant "superbugs!" Find out how these superbugs can develop in this activity by rolling dice to model how different bacteria respond to an antibiotic treatment. 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 Can Vaccines Be Used to Fight Outbreaks?

Science Fair Project Idea

Scientific Method

Stopping a viral outbreak like COVID-19 takes more than luck, it takes public health tools. Vaccines are considered to be one of the best public health tools, which is why there is often a rush to develop good vaccines for newly discovered viruses, particularly those that have the potential to infect lots of people. Recent examples include COVID-19, Zika virus, and Ebola. If enough people are vaccinated, an effective vaccine can help stop outbreaks or even eradicate (completely get rid of) a… 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 Food Preservatives Affect the Growth of Microorganisms?

Science Fair Project Idea

Scientific Method

This project uses liquid cultures and agar plates to investigate the effects of different concentrations of a food preservative on microbial growth. 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
