Cryopreservation: Freezing Plant Tissues

Science Fair Project Idea

Scientific Method

Cryopreservation—storing seeds in ultra-cold liquid nitrogen—is one method for maintaining plant genetic stocks in seed banks. Can seeds withstand a really deep freeze and still germinate? Read more

What is the Rate of Leaf Growth Along the Stem?

Science Fair Project Idea

Scientific Method

Leaves grow in a different pattern than stems and shoots. They do not elongate along one axis, but instead spread out over time. Do all regions of the leaf grow equally? You can use markings on different regions of a growing leaf to see if the whole surface grows, or if growth is focused in a particular region, like the veins or edges of the leaf. If you look along a leafy stem, you may notice that leaves at different positions along the stem are different sizes. You can do an experiment to… Read more

Drag Racing in the Water

Science Fair Project Idea

Scientific Method

It's fun to go swimming! To feel the power of your body as you launch yourself into the water. But did you know that swimming isn't just about skill and athleticism? The human body consists of skin, contours, and curves. How the water moves along your body and the clothing you are wearing determines how fast you can go. In this science fair project, you will investigate the effects of a force called drag. You will compare the time it takes to swim 25 meters in a swimsuit versus swimming the… Read more

Tasty Arrangements: How to Position Food in Microwave Cooking

Science Fair Project Idea

Scientific Method

When you think of successful inventions from the 1900's that have dramatically changed how people live, what comes to mind? The car? Radio? TV? The computer? What about the microwave oven? You might not remember a time when microwave ovens were not a standard part of most kitchens, but your parents or grandparents probably do. They can remember when heating leftovers took a good 30 minutes in a traditional oven. Or thawing a food from the freezer meant leaving it in the refrigerator overnight.… Read more

Burning Biofuels: Comparing Nonrenewable and Renewable Fuels

Science Fair Project Idea

Scientific Method

Have you considered where the gasoline that your parents put in your car comes from and how long that source will last? The fuel that most vehicles use, gasoline, is a petroleum product. Petroleum is a fossil fuel and is a nonrenewable form of energy, meaning we use it faster than it is able to be reproduced. Burning fossil fuels also produces pollutants that might hurt our environment. Using a kind of fuel from a renewable source would help save Earth's natural resources and cut down on… Read more

Squishy Robot Simulator: Physics Settings

Science Fair Project Idea

Scientific Method

In our introductory VoxCAD project, we provided you with a template file that included default material properties and physics simulation settings. These settings include friction, gravity, and temperature — all of which can drastically change how fast your robots move. However, we did not explain what exactly all these physics simulation settings meant, or how to change them. You can access the physics settings through the Physics Settings tab after entering the Physics Sandbox mode, as… Read more

Respiration and Gills: What Factors Affect Respiration in an Aquatic Environment?

Science Fair Project Idea

Scientific Method

During metabolism, organisms experience physical and chemical changes. All animals need some way to exchange chemical waste generated during metabolism for fresh nutrients. One way that these metabolic chemicals are exchanged is during respiration, the process by which used carbon dioxide gas is exchanged with fresh oxygen and circulated throughout the body. How do organisms living underwater respirate? They use gills, which filter oxygen from the water and pass the oxygen into the… Read more

Pop Goes the Geyser!

Science Fair Project Idea

Scientific Method

Our home, Earth, is a living planet. Earthquakes and volcanic eruptions are proof that the geological forces that shaped our planet and created the land masses are ongoing. An amazing example of geologic activity that is less damaging is a geyser. In this geology science fair project, you will build a model geyser and determine how depth of the source affects how the water is ejected. By the end of this project, you will know a lot more about geysers and understand that a geyser is much more… Read more

Do Heavy Loads Shorten Your Steps?

Science Fair Project Idea

Scientific Method

You probably notice that when you carry something heavy—whether it’s a backpack filled with books, grocery bags, or a weighted vest—the way you walk changes. Your body adjusts in many ways to maintain balance, avoid fatigue, and reduce injury risk. One of these adjustments happens in your step length—that is, how far you move forward with each step. Biomechanical studies show that adding extra load (weight) often causes people to take shorter, more cautious steps. This… Read more

Water-Wise: Building a Rainwater Collection System

Science Fair Project Idea

Scientific Method

We are all familiar with the nursery rhyme, "Rain, rain, go away, come again some other day...", or the song "Singin' in the Rain." Numerous songs and stories describe our feelings about rain. Why so many? Because we humans understand how important rain is to our well-being. Rainfall, as part of the water cycle, brings water back to Earth that had previously evaporated or transpired from the surface. When water vapor in the atmosphere condenses into clouds and falls back to Earth as rain,… Read more
