Science Fair Project Idea

Scientific Method

Looking for an exciting new mode of transportation? In this science fair project, you will build a working hovercraft that will glide over surfaces on a cushion of air. And it's simpler to build than you might think! Read more

Ring of Fire 1: What Volcanoes Tell Us About Plate Tectonics

Science Fair Project Idea

Scientific Method

The Ring of Fire is a region of volcanic and earthquake activity that surrounds the Pacific Ocean. In this project you can explore the connection between plate tectonics and volcanic activity by mapping historical data. Read more

Ring of Fire 2: What Earthquakes Tell Us About Plate Tectonics

Science Fair Project Idea

Scientific Method

Today it is widely accepted that the Earth's crust consists of a series of huge plates that slowly move. The low parts of the plates are beneath the world's oceans, and the high parts of the plates are landmasses. New plate material is generated at deep sea ocean ridges in a process called sea-floor spreading. Material from plates is also recycled at trenches, where dense, oceanic crust dives back (subducts) underneath an adjacent plate towards the upper mantle. Figure 1 shows a map of the… Read more

Rise to the Occasion: Investigating Requirements for Yeast Fermentation

Science Fair Project Idea

Scientific Method

Did you ever wonder how yeast makes bread dough rise? This project will show you what yeast does to make this happen. You'll also investigate the conditions yeast needs to grow. Read more

Rocket Catcher Challenge

Science Fair Project Idea

Engineering Design Process

Inspired by real-world reusable rockets, in this engineering challenge, you will design and build a device to catch a falling rocket so it lands vertically. Drop the rocket from higher and higher heights to get a better score! The 2025 Science Buddies Engineering Challenge is over, but you can check out this page to see our other past engineering challenges and what this year's challenge will be! Teachers, lesson plan versions of this challenge are also available. Read more

Rocket Science: How High Can You Send a Payload?

Science Fair Project Idea

Scientific Method

Rockets are definitively an engineering challenge. These amazing gravity-defying machines have lifted test material, people, and even animals into space. Feel like building one yourself? In this science project, you will transform a water bottle into an aerodynamic bottle rocket with two compartments, one for the fuel and one for a payload. You will then test how well it performs when lifting mass vertically up into the air. Ready, set, soar! Read more

Rocking the Boat

Science Fair Project Idea

Scientific Method

When a ship rocks back and forth, it can make people seasick. Even worse, it can make it dangerous for jets to land on aircraft carriers. For these reasons and many others, it's important for engineers to design bilge keels (or fins) to keep boats from rolling back and forth. Become an engineer for a day and discover the best way to keep from rocking the boat in this engineering science fair project! Read more

Rooftop Gardens: Are They a Cool Idea?

Science Fair Project Idea

Scientific Method

Would you like some sky vegetables for dinner? How about some fresh-cut roof flowers to put in vases in your house? Around the world, rooftops are being transformed into living green expanses. Besides beauty, rooftop gardens have a number of advantages, including growing food and taking carbon dioxide out of the air while releasing breathable oxygen. But can rooftop gardens also keep your house cooler and lower your energy bill? Try this science fair project to find out. Read more

Rubber Band Car Challenge

Science Fair Project Idea

Engineering Design Process

In this engineering challenge, you will build a car powered by nothing but a rubber band. The farther the car goes, and the fewer materials you use to build it, the higher your score. The 2024 Science Buddies Engineering Challenge is over, but you can check out this page to see our other past engineering challenges and what this year's challenge will be! Teachers, lesson plan versions of this challenge are also available. Read more

Rubber Band Elasticity and Temperature

Science Fair Project Idea

Scientific Method

Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures? Read more
