Do Different Tree Species Grow at the Same Rate?
Science Fair Project Idea
Scientific Method
Trees grow more during the early spring than they do the rest of the year. Because of this period of dormancy, or lack of growth, each year of growth is marked by a line called a tree ring. You can count the number of rings in the cross section of a tree trunk to show how old the tree is. You can also count the number of rings in a stem to see the age of a stem or branch. One way to measure the rate of growth of a tree is to count the number of rings per inch. Trees with high numbers of… 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
Do Males and Females Play the Same Types of Games?
Science Fair Project Idea
Scientific Method
There are many different types, also called genres, of computer and video games, including racing, fighting, sports, adventure, and puzzle games. Do some genres of games appeal more to males and other genres more to females? Survey your classmates and find out in this science fair project! Read more
Do Migratory Birds Like It Hot?
Science Fair Project Idea
Scientific Method
Why do birds migrate? Do all birds have the same reasons for migrating? Where do they go when they migrate? These are questions scientists have asked for centuries. The more species for which they gather data, the more specific the answers become. In this science project, you will choose a species to investigate, then access and evaluate real data collected by scientists to start answering those questions yourself! Read more
Do Milkweed Bugs Show a Color Preference for Egg-Laying Sites?
Science Fair Project Idea
Scientific Method
Milkweed bugs, as their name suggests, have a close relationship with the milkweed plant. The plant produces an irritating, milky sap, and toxic compounds, but somehow the milkweed bug is unaffected by them. Instead, it concentrates chemicals from the sap in its body, acquiring an unsavory taste that, along with its bright coloration, protects it from predators. Given this close relationship, will the milkweed bug exhibit a color preference for egg-laying sites? This project is designed to find… Read more
Do People Use Different Passwords for Different Accounts?
Science Fair Project Idea
Scientific Method
Do you ever use a password to log in to a computer, email account, or website? Do you use the same password for each one? Even if your password is very long or hard to guess, using the same password for many accounts can still be risky. If someone manages to find out your password (for example, via a phishing attack, or if you write your passwords down and someone finds the piece of paper), they could easily access many of your accounts. However, memorizing lots of different passwords can be… Read more
Do Preferences Bias Our Choices?
Science Fair Project Idea
Scientific Method
What is your favorite color and why? Do you think that simple tasks might be biased by your preferences? Find out in this science project if your color preferences will bias your fine motor skills when doing quick, repetitive tasks. Read more
Do the Eyes Have It?
Science Fair Project Idea
Scientific Method
Some people have a photographic memory and can memorize anything they see almost instantly! Wouldn't that make homework easy? Other people can remember almost anything they hear. Try this experiment to see which type of memory you have. Read more
Do Video Game Players Have Faster Reaction Times Than Non-Players?
Science Fair Project Idea
Scientific Method
When someone yells, "Think fast!" and throws you a ball, are you able to catch it? When the bell rings at the end of class, are you the first one out of your seat? Can you make it through a sudden hairpin turn in a video game without crashing? If so, then you likely have quick reaction times. In this science fair project, you'll look at reaction times (how fast people react to sensory events), and see if people who play video games have faster reaction times than those who do not. Read more
Do You Have the Willpower to Taste Something Sour?
Science Fair Project Idea
Scientific Method
If you developed a super-sour candy, drink, or dessert, to whom would you sell it? Do people of all ages love sour, or is there a difference between the sour preferences of kids and adults? In this mouth-puckering science project, you will find out by making batches of lemonade that vary in their sourness and have volunteers taste them! Read more
