Design a Game to Help Alzheimer's Patients

Science Fair Project Idea

Engineering Design Process

Alzheimer's disease and dementia affect millions of people around the globe. Can you design a "brain training" game that can help people keep their brains healthy as they age, and maybe one day help treat or even prevent diseases like Alzheimer's? Try this coding science project to find out! Read more

Design Your Own Slime

Science Fair Project Idea

Engineering Design Process

There are many different kinds of slime out there. Some slime is runny and liquid-like; other slime is thick and rubbery. Some slime glows in the dark, some is fluffy, and some is even magnetic! What set of properties makes the best slime? What kind of slime would you choose to make if you were selling slime as a toy in your own "slime shop"? In this project, you will experiment with different slime recipes and try to perfect one to make the best slime. Read more

Determining Iodide Content of Salt

Science Fair Project Idea

Scientific Method

Have you ever noticed that the salt you are using says it is "iodized"? Iodine is an important micronutrient, which means we need it in small quantities to be healthy. Because iodine is rare in many people's normal diets, it is added to table salt. Then when people salt their food, they are also adding this important micronutrient. In this food science project, you will use some kitchen-friendly chemistry to investigate which types of salt have iodine added (in the form of iodide) and which do… Read more

Dice Probabilities

Science Fair Project Idea

Scientific Method

You're playing Monopoly with a friend, and you've already got Park Place and you really, really want to get Boardwalk. If you're on Pacific Avenue, what are the chances you'll reach your goal? Here's an easy project that will show you how to find out. Read more

Digital Photos and Dynamic Range

Science Fair Project Idea

Scientific Method

Digital cameras can be a great way to learn about photography. Most digital cameras today have LCD screens, so you get instant feedback on your photo. If you make a mistake, no problem, you just delete the picture. It's nice that you don't have to worry about the expense and bother of developing film! This project can help you learn to take better pictures. Read more

Distance and Constant Acceleration

Science Fair Project Idea

Scientific Method

Have you ever dropped something and wondered how fast it was moving while falling? If it was something fragile, like a cell phone, you might not have been thinking about this at the time — you may have been too busy trying to grab the phone! But you probably wanted to find out just how hard it hit the ground afterwards. We know that gravity forces an object to fall, but how does this affect how quickly something falls and how hard it hits the ground? For example, did the phone move faster… Read more

Divide and Conquer: Proving Pick's Theorem for Lattice Polygons

Science Fair Project Idea

Scientific Method

If you like to play Tetris, then you might like this project. You will learn something interesting about the mathematics of complex shapes as you try to prove Pick's Theorem. The strange shape below is an example of a lattice polygon, which is a polygon whose vertices lie on points in the plane that have integer coordinates. As you can see, it is a complex shape, but there is an easy way to calculate its area, by simply counting lattice points! If you count the number of lattice points on… Read more

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 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 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
