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

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

PID Controller Tuning for a Drone

Science Fair Project Idea

Engineering Design Process

Note: to do this project you will need the DIY Mini Drone Kit, available from our partner Home Science Tools®. An Arduino must be purchased separately. The Electronics Kit for Arduino, available from our partner Home Science Tools®, contains the additional parts you will need, including an ultrasonic sensor. The program in the DIY Mini Drone: Arduino™ Altitude Control project uses a proportional controller to control the drone's altitude. A potentiometer is connected to one… Read more

Pinwheel Magic: Take a Spin with Animation

Science Fair Project Idea

Scientific Method

Do you enjoy watching cartoons and animated movies? Do you have fun playing video games? What do all of these things have in common? Fantastic computer animation, that's what! It's a cool job to take an interesting story or game and make it more entertaining by animating it. In this computer science project, you won't animate a full-length feature movie, but you will animate a pinwheel—a project that can go a long way toward creating your own longer animations! You will create an animated… Read more

Pinwheel Science: Weekly Science Activity

Blog Post

In this week's spotlight: an energy-focused family science experiment that explores the relationship between the potential power of a wind turbine and the source and location of the wind. Using a pinwheel, students create their own horizontal-axis wind turbine and experiment to see how the pinwheel spins when the wind comes at it from different directions—and how this translates into how much weight the wind turbine can lift. A pinwheel is a simple example of a wind turbine, but with… Read more
