Make your own 3D printed "impossible arrow" illusion in this fun activity. No matter how many times you spin the arrow around, it always seems to point in the same direction—but its reflection in a mirror points the other way! How does it work? Try it and find out! Read more

The Moon and the Stars

Science Fair Project Idea

Scientific Method

Everyone loves looking at the full moon, but are these nights the best time to go stargazing? Can the moon interfere with certain astronomical observations? Read more

The Power of Your Eyes: How Vision Affects Balance

Science Fair Project Idea

Scientific Method

Staying balanced might feel simple, but there’s so much more involved than you would think! The way your body balances is actually the result of several body systems working together. Your muscles and joints provide feedback (proprioception) about where your body is in space, your inner ear senses movement and position, and your eyes give you important visual cues about your surroundings. Vision is especially important because it helps your brain judge where you are in relation to the… Read more

Have you ever watched a train roll by? If so, you might have wondered how the train is able to stay on its tracks. The secret lies in the train's wheels. Although they seem cylindrical at first glance, when looking more closely you will notice that they have a slightly semi-conical shape. (Of course, never get close to a working train!) This special geometry is what keeps trains on the tracks. In this activity you will put different wheel shapes to the test to find out why the conical wheel is… Read more

Understanding Wolf Behavior from GPS Tracking Data

Science Fair Project Idea

Scientific Method

If you were leaving home for a long walk, how far would you go? One mile, 5 miles, 10 miles? How about 550 miles?! That's a long way, but some wolves have been known to travel that far when they are leaving their packs in search of a mate so they can form their own pack. But is that how far wolves normally travel? Try this wild wolf tracking science fair project to find out! Read more

Use a Catapult to Storm Castle Walls

Science Fair Project Idea

Scientific Method

You may have seen movies or read books where armies in medieval times catapulted large rocks or other objects at castles (or each other!). These armies used different types of catapults to accomplish different goals — for example, launching things over or into castle walls to knock them down. In this experiment, you will use a ping-pong ball catapult to lay siege to a "castle" and find the right settings to hit your targets. Read more

Which Cheesecake Baking Method is the Best?

Science Fair Project Idea

Scientific Method

Since ancient times, nothing has said "special" and "dessert" quite like cheesecake! The Romans even sacrificed their form of cheesecake, called libum, in religious ceremonies. Modern cheesecakes are more likely to be eaten at parties and at restaurants than used as sacrificial offerings, but no matter how they're enjoyed, all cheesecakes require some finesse in their baking and mixing to avoid common cheesecake faults, like cracking, collapsing, or failure to rise. In this cooking and food… Read more

Which Is the Better Insulation Material?

Science Fair Project Idea

Scientific Method

You've probably noticed that the price of gasoline has been going up and up lately. Heating oil will probably cost more this winter than last winter, too. Using good insulation material is one way to conserve energy and save money. What insulation materials work better than others? Read more

Which Stars Can You Use for Navigation in Different Parts of the World?

Science Fair Project Idea

Scientific Method

Do you ever wonder how pirates sailed the seven seas? The two most important things a pirate could have (besides a parrot and big hat) were a compass and an accurate watch. Ancient navigators didn't know about compasses, so how did they know where they were going? Could they have used the stars to know which way to go? Read more
