Dog Toys: What Makes One a Favorite or a Flop to Fido?

Science Fair Project Idea

Scientific Method

Got a pampered pooch in your household? Then you know how much most dogs love their toys. And not just any toy. It has to be that particular beat up ball, gnawed frisbee, or ratty not-so-plush-anymore bunny with only one eye and partial ear remaining. Seems that dogs, like people, have definite preferences for their play things. This fun project investigates what makes a toy interesting to a dog. In these experiments, you and your dog can have some fun while you learn about canine behavior… Read more

Exploring Nanotechnology: Fold, Roll, & Stack Your Way to Super-Strong Materials

Science Fair Project Idea

Scientific Method

Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far? The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse… Read more

Exploring the Uncanny Valley

Science Fair Project Idea

Scientific Method

What do you consider creepy? Clowns? Zombies? Video game characters with jerky movement? In 1970, a roboticist by the name of Masahiro Mori suggested that people are "creeped out" by robots that are almost, but not exactly, humanlike. He called this phenomena the uncanny valley. But researchers are still exploring and defining the uncanny valley. In this science project, you can do your own exploration—just try not to creep your friends out too badly! Read more

"Fresh Food In Garbage Can to Illustrate Waste" by SpeedKingz/Shutterstock.com Have you ever thrown away food after a meal? Have you ever thrown away a whole piece of food? What are some of the reasons you threw away that food? During this Food Waste Audit, students will explore their own impact on our food system. Students will brainstorm solutions to reduce their food waste and be challenged to try out their solution! Read more

"Nuclear Power Plant Cattenom" © 2005 Stefan Kühn In these two activities, students will explore two consequences of burning fossil fuels: air pollution and the greenhouse effect. For a comprehensive unit on fossil fuels, this lesson works especially well as an extension to Fossil Fuels: Chocolate Chip Mining. Read more

NGSS Performance Expectations:

4-ESS3-1. Obtain and combine information to describe that energy and fuels are derived from natural resources and that their uses affect the environment
MS-ESS3-4. Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.

Did you know that gears are all around you? You can find them in wind-up toys, bicycles, carousels, cars and trucks, cranes, drills, wind turbines, analog watches, and so forth! If you've looked closely at a moving bicycle, you have seen gears at work. Are you curious about their purpose? In this activity you will use candy to make gears and explore why they are so versatile. Read more

Gears-Go-Round!

Science Fair Project Idea

Scientific Method

Music boxes, bicycles, and clocks all have one thing in common: GEARS! You might say that gears make the world turn, since they are in so many mechanical instruments. How do they work and how do you know which gears to use? Find out in this simple experiment. Read more

Generate Recipes from YouTube Videos with AI

Science Fair Project Idea

Engineering Design Process

This project explores how large language models (LLMs) can generate recipes from YouTube cooking videos. In this science project, you will learn how LLMs interpret language and how prompt design can affect results. Read more

Do you ever wonder why we perform tasks in a particular way? Very often, we learn by copying someone and never stop to question if there is a more efficient or easier way to do something. This activity is about the tricky task of pouring from a full container. Could there be an easier way to do it? Read more

Go with the Flow: Model Rivers with Cornmeal, Sand, & Water

Science Fair Project Idea

Scientific Method

Have you ever had fun playing with sand and water, observing how little rivers you create carve their way down to the lowest point of the sandbox, backyard or beach? Some meander, others braid, and some carve a path straight down. Hyrdologists (or scientists who study water) do very much the same thing! Only they set up the model in a particular way, so observing their mini-rivers helps them answer questions about how water flow affects the environment. In this geology science project, you… Read more
