‘See a penny pick it up, all day long you’ll have good luck!’ – maybe you’ve heard this phrase before, and maybe you’ve even stopped to pick up a lucky penny off the sidewalk. But sometimes those pennies you see on the ground look anything but lucky. They look brown or black, and sometimes they’re so dirty looking that you can’t even tell whether they’re pennies! In this activity we’re going to explore why pennies don’t… Read more

Have you ever wondered how fast a heavy object falls compared to a lighter one? Imagine if you dropped both of them at the same time. Which would hit the ground first? Would it be the heavier one because it weighs more? Or would they hit the ground at the same time? In the late 1500s C.E. in Italy, Galileo was actually asking some of these same questions and did some tests to answer them. In this activity, you’ll do some of your own tests to determine… Read more

Simulate Microchip Clean Room Contamination with Crayon Leaf Rubbings

Science Fair Project Idea

Scientific Method

Have you ever made a leaf rubbing or imprint using paper and crayons? What do you think would happen if you got dirt or sand on the leaf? Would it mess up the result? In this project you will find out and learn about how this is related to the process of making the microchips that run our phones, computers, and other electronic devices. Check out this page for more science projects related to this process. Read more

Simulating The Kessler Syndrome: How Satellite Collisions Could Spiral Out of Control

Science Fair Project Idea

Engineering Design Process

What happens when a satellite collision in space leads to a chain reaction of more collisions? This project models The Kessler Syndrome: A scenario in which collisions between satellites in low Earth orbit create increasing amounts of debris, eventually making the region too dangerous for satellites or spacecraft to operate safely. By adjusting key variables like collision rates and debris generation, you can visualize how quickly space around Earth could become overcrowded, and explore… Read more

Have you ever looked at a package of dry yeast and found it hard to believe that it contains organisms that are alive? Add the right ingredients and presto, the mixture becomes a bubbly, oozing, mess of life! But what are the conditions that are needed for this to happen? What does that yeast need to become active and thrive? Try this science activity to find out for yourself! Read more

Skeleton Building

Science Fair Project Idea

Scientific Method

Do you like skeletons? One of the more interesting jobs at a natural history museum is the creation and care of the skeletons and bones. How do the curators clean and put together the skeletons? Many curators use the carrion beetle, Dermestes vulpinus, to quickly clean off the dead animal tissue from a corpse to reveal the skeleton. These insects do such a good job that sometimes the skeleton remains intact! Another method is to slow cook the carcass until the meat falls off. You can use… Read more

Skipping Science: An Experiment in Jump Rope Lengths

Science Fair Project Idea

Scientific Method

Did you know that the world record for the greatest number of jumps in a minute is more than 340? That's more than five jumps a second! How close do you think you can get to that number? If you are going to try to break the record, it might be important to figure out how jump rope length affects your success. Try your hand at this skipping science fair project and jump-start your chances for a jump rope record. If you have a smartphone available, you can use its accelerometer and a sensor app… Read more

Skunk Attack! Test Different Remedies to Remove Skunk Odor

Science Fair Project Idea

Scientific Method

Have you or one of your pets ever been sprayed by a skunk? Hopefully not, but if you have, you probably know that the smell can be very unpleasant and hard to get rid of. There are many "folk remedies" for getting rid of skunk scent, but if you ever do get sprayed by a skunk, how will you know which one to try? In this science project, you will test the ability of various mixtures to remove the bad scent from rags that have been contaminated with bottled skunk scent, and determine which one… Read more
