Now You See It, Now You Don't: Investigating Inattentional Blindness

Science Fair Project Idea

Scientific Method

Have you ever taken notes from the chalkboard during class and not noticed what was going on around you? Or have you ever been so focused on a task that you haven't seen other people around you? In both of these cases, you were paying attention, but you were seeing without seeing! This is called inattentional blindness and it's the topic that you will investigate in this human behavior science fair project. If you are interested in how the human brains perceives information, then this might… Read more

Observing Nature: Doing Fun Science at Home during School Closures (Activity #4)

Blog Post

Follow along with a Science Buddies parent who is using family STEM activities to keep her kids learning at home during the COVID-19 school shutdown. New posts every Monday, Wednesday, and Friday. Today's adventure... a neighborhood walk leads to pulling apart flowers, all in the name of science. Observing Nature Means a Little More Sanity It's been exactly two weeks since school closed for us, and I've learned a lot about each of my family members,… Read more

Ocean Currents and Weather

Science Fair Project Idea

Scientific Method

Ocean currents have a huge impact on our weather. If not for the ocean currents, the global climate would be similar to an ice age. Do you live near the coast? Find out which currents are near your coastline. How do they affect your climate? Where do they come from? Do they bring colder or warmer water to your area? Are they seasonal? What do you think your area would be like without them? Every three to seven years there is a weather phenomenon called El Niño, which is caused by… Read more

Oil and Vinegar Do Mix…When You Have an Emulsifier

Science Fair Project Idea

Scientific Method

In this cooking and food science fair project, you will explore the role of proteins as emulsifying agents. Emulsifying agents are substances that are soluble in both fat and water and enable fat to be uniformly dispersed in water as an emulsion. Foods that consist of such emulsions include butter, margarine, salad dressings, mayonnaise, and ice cream. Emulsifying agents are also used in baking to aid the smooth incorporation of fat into the dough and to keep the baked goods tender. Natural… Read more

Old Salty: Does Age Affect the Ability to Detect Salt?

Science Fair Project Idea

Scientific Method

Sauerkraut, pickled fish, pickled vegetables, kimchi, corned beef, processed cheeses, smoked lunch meats. Do you like these high-salt foods? What about your grandparents, do they? Do your grandparents seem to like most foods to be a bit saltier than you do? Try this science fair project if you want to find out more about the incredible, edible rock known as salt, and why people vary in how much of it they like to eat. Read more

Only If They Think They Can Get Away with It?

Science Fair Project Idea

Scientific Method

How many times have you seen a car without the appropriate permit (either a license plate or placard that hangs from the rearview mirror) parked in an accessible parking space reserved for people with disabilities? If you find this behavior upsetting, you might be interested in figuring out how to discourage "cheaters" who use these spaces to make a quick trip into the store. Is it enough to let them know someone might be watching? Read more

Paper Maze Programming: Start to Finish Computer Logic

Blog Post

Explore the logic of computer coding — no computer required! Have you ever asked your student to give you directions, turn by turn, to get you home from a familiar landmark? It can be eye opening to hear how they might guide you, and you may or may not make it where you need to go! But the process of giving directions helps reiterate the steps involved in moving along a frequent path. Writing a computer program is similar in many ways. You need… Read more

Do you have your own email or social media accounts? If so, you probably use a password to log into them. How did you pick your password? Is it something that might be easy for someone else to guess, like the name of your pet? This fun activity will teach you about password security and how to pick a stronger password. Read more

Pet Poll: A Taste Test for Fluffy & Fido

Science Fair Project Idea

Scientific Method

Has your dog ever barked, seemingly for no reason at all? Or has your cat ever stopped and carefully smelled a spot that looked perfectly clean to you? Pets, like people, have senses that they use to learn about and to react to their world, but their senses can be stronger or weaker than people's. In this mammalian biology science fair project, you'll study your pet's sense of taste by conducting taste tests and watching how your pet acts to determine his or her favorite type, flavor, or brand… Read more

Phone Book Friction Physics

Blog Post

Explore the physics of friction using sticky notes. What happens when you interleave the pages of two books or pads of paper? Why? The friction between two objects determines how difficult it will be to slide one object across another. Friction accounts for how your feet move across grass, for example, compared to how an ice skate moves across ice. Scientists use both the coefficient of friction and measurement of normal force to talk about how much… Read more
