Using Weather Balloon Data to Map Atmospheric Temperature

Science Fair Project Idea

Scientific Method

Snow-capped mountains make a picturesque scene, especially in summertime when the peaks are in such contrast to the warmth below. This project shows you a way to see how temperature changes with altitude using data collected twice daily from weather balloons. Read more

Volcanoes

Science Fair Project Idea

Scientific Method

The papier-mâché volcano is a real classic, but there are many other ways to make an even more exciting and interesting science project focused on volcanoes! To get started on your own volcano-based science project, you will want to first have an understanding of how volcanoes form. This is related to tectonic plates. The entire outer shell of the Earth, known as the lithosphere, is made up of tectonic plates that are constantly moving. There are seven or eight large tectonic… Read more

What A Drag!

Science Fair Project Idea

Scientific Method

What makes some objects more streamlined than others? Find out which ordinary objects around your house are made to move smoothly through the water in this easy science fair project. Which objects will produce the most drag when pulled through the water? Read more

What Bone Do Children Break Most Often, and What Is the Main Cause?

Science Fair Project Idea

Scientific Method

Here's a project that will give you insight into accidents, and maybe help you prevent them. The original project used a survey method to gather data, which you could also do. Another approach for data collection that you might try would be to use published articles from the pediatric medical literature. Finding a pediatrician or pediatric orthopedist who is willing to be your mentor for this project would be helpful. (Idea from Caito, 2003) Read more

What Color Are the Leaves Really Turning?

Science Fair Project Idea

Scientific Method

Everyone loves the beautiful colors of fall, but where do they come from and how does the change in colors happen? In this project, you will uncover the hidden colors of fall by separating plant pigments with paper chromatography. What colors will you see? Read more

What Conflicting Mental Tasks Reveal About Thinking: The Stroop Effect

Science Fair Project Idea

Scientific Method

Can you pat your head with one hand while you rub your stomach with the other? This science project idea is kind of like doing that, but this project can actually give you some insight into how your mind works. The task is to name colors. It sounds simple enough, but see what happens when color words get in the way. Read more

What Do Different Baking Ingredients Do?

Science Fair Project Idea

Scientific Method

If you like to bake, this might be an interesting project for you. When you're following a recipe, do you ever wonder why certain ingredients keep showing up time after time (e.g., baking powder in quick breads)? Do you notice that certain ingredients tend to occur in a particular ratio to one another (e.g., amount of shortening and sugar, or amount of shortening and flour, or number of eggs and amount of flour)? What happens if you use more or less of an ingredient than the recipe calls… Read more

What Is Home Sweet Home to a Bug?

Science Fair Project Idea

Scientific Method

If you had to choose between having your favorite dessert, going to a movie, or spending the night at a friend's house, which would you choose? This science project shows you how you can "ask" a sowbug (or pillbug) a similar question in order to learn about their preferences. Give it a try to find out what types of microenvironments these tiny crustaceans prefer. 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

What Makes a DNA Fingerprint Unique?

Science Fair Project Idea

Scientific Method

Do you like solving mysteries? In this experiment, you can find out how a DNA fingerprint can help you figure out whodunit. The answer might just be in the "sequence" of events! Read more
