Have you ever looked through a magnifying lens? Why does an object look different when you look at it through the magnifying lens? Even though the object appears to get larger or smaller, it really stays the same size. Each lens has its own unique power of magnification; how powerful is your lens? Read more

A Matter of Time

Science Fair Project Idea

Scientific Method

Do you wake up at the crack of dawn, or do you need an alarm clock to wake you up each morning? It may surprise you that the two are not always in synch. Nowadays, we use Standard Time to set our watches instead of Solar Time. Which method of timekeeping is the most accurate? Get ready to synchronize your watches! Timekeeping is the science of how to keep time with precision and accuracy. People have been finding ways of measuring time for thousands of years, usually based on the movements… Read more

A Robot Waiter That Can Carry Drinks

Science Fair Project Idea

Engineering Design Process

Have you ever seen a waiter balance an entire tray of drinks without spilling any? How do they do it? Do you think you could build a robot waiter that can do the same thing? In this project, you will learn how to build a self-balancing robotic tray. You can incorporate the auto-leveling tray into one of our many other robotics projects, like the Bluebot or robotic arm.

If you want a cool project that you can show to your friends, this activity is for you! Take a potato and a straw—maybe a pencil as well—and challenge your friends to drill holes into the potato with the least amount of effort. Chances are, they will not find a method that gets the job done with ease. The best method—the method that requires the least effort from you—will surprise them all! Experiment, investigate and have fun! Can you find a reliable way to get the job… Read more

A Soluble Separation Solution

Science Fair Project Idea

Scientific Method

Have you ever mixed together salt and sand? It is fun to see how all of those tiny grains of salt and sand mix together! But what if you had to separate them out again? Do you have nightmares of tiny tweezers, a magnifying glass, and hours spent picking grains of salt and sand apart? Do not be afraid, there is another way! In this chemistry science project you will use the differences in solubility between salt and sand to find out the simple "solution" to this problem. Read more

A Study of Gender Responses to Frustration

Science Fair Project Idea

Scientific Method

Have you ever felt really frustrated? Maybe you were playing a video game and could not easily figure out a particularly challenging puzzle. Or maybe there was something you really wanted but you could not have it for some reason. However it has happened, what do you do when you get frustrated? What about other people — what kind of behaviors have you seen others display when they get frustrated? Do they cry, jump up and down screaming, just give up, or become aggressive? In this human… Read more

Have you ever thought about what type of ground buildings are constructed on? Rock, gravel, sand, soil and many others—there are lots of different types of "ground." And this issue becomes especially important in areas that are likely to get earthquakes. In this activity you will build a sweet building on a homemade shake table and find out how an earthquake impacts buildings constructed on landfill. How will your structure perform in a pretend earthquake? Read more

A Toxic Test: Can Plants Be Genetically Resistant to Heavy Metals?

Science Fair Project Idea

Scientific Method

Have you ever wondered why a plant that grows well in one environment may not survive in a different environment? For example, plants that grow well in a wet jungle would probably not do so well in a dry desert, lacking enough water. This is because plants have adapted to their specific environment. Some plants have even adapted to tolerate chemicals that would usually be toxic, such as various heavy metals. In this plant biology science project, you will investigate whether different varieties… Read more

Adding Art: Doing Fun Science at Home during School Closures (Activity #6)

Blog Post

Follow along with a Science Buddies parent who is using family STEM activities to keep her kids learning at home during the COVID-19 school shutdown. New posts every Monday, Wednesday, and Friday. Today's adventure...food dye, shaving cream, and a bit of cool science transform paper into beautiful marbled art. Artists are Scientists, Too My kids love art. Drawing, painting, clay — all these things bring them joy. On the other hand, while I… Read more

Aerodynamics of a Football

Science Fair Project Idea

Scientific Method

How much difference does the spiraling motion of a well-thrown football make on the distance of the throw (compared to wobbling, or end-over-end motion of the ball)? Think of a way to reproducibly produce the desired ball motion and launch it with a constant force to find out. (For more information on the physics, see Gay, 2004.) Read more
