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

Is Thanksgiving one of your favorite holidays of the year? All your friends and family are getting together to celebrate. The table is full of delicious food—a big feast—and there might even be some fancy China and glassware on the table to make the celebration even more special. Who can resist the temptation to make the wine glasses sing? You have probably done this many times before, but have you ever wondered, why the wine glass makes this sound? Do this activity, and you will… Read more

Slip Sliding Away: Experimenting with Friction

Science Fair Project Idea

Scientific Method

As you headed up the mountain to enjoy your last ski trip, you may have noticed a sign reading: Hazard! Icy Roads Ahead—Put On Your Chains. Putting chains on car tires increases the resistance between the tires and the road allowing the car to "grip" the road. This resistance to sliding is called friction. In this experiment, you will be investigating how to increase and decrease the friction between two surfaces. Read more

Space elevators zipping people and materials up into space might seem like a very futuristic and improbable idea, but is it that difficult? This activity will guide you through the mathematics. Try it out and see what is possible with materials that can be produced with current technology. Read more

Space Radiation Protection

Science Fair Project Idea

Engineering Design Process

The radiation sources recommended in this experiment are low-dose radioactive sources and do not require a license to purchase; they are safe to work with as long as these common-sense safety tips are followed: Wear disposable gloves when handling any radioactive source. Never rub your eyes or mouth while you are handling the radioactive source. NEVER swallow any radioactive source and use protective glasses when bringing a source within a few inches of… Read more

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 were likely too busy trying to grab the phone! But you probably wanted to find out how hard it hit the ground afterwards. We all know that gravity forces an object to fall, but how does this affect how quickly something falls and its impact? For example, did the phone move faster right after leaving… Read more

Spinning Colors: How Do Primary Colors Combine to Make New Colors?

Science Fair Project Idea

Scientific Method

Did you know that sunlight can actually be separated into the colors of the rainbow? And the light of different colors can be added together to make white light or new colors. This is an area of study where art and science overlap. In this science fair project, you will explore this area by drawing or painting "pie slices" onto a white circle and then combining them to make a new color by spinning the wheel using an electric drill.

Have you ever helped your parents cook a pot of spaghetti? Strands of spaghetti are pretty long, so sometimes people break them in half so they fit into the pot more easily. How exactly does the spaghetti break? And what does this have to do with science? It turns out engineers and materials scientists study how materials break when they are bent. While professional engineers might be more concerned with steel beams in a bridge, you can still do a fun experiment with some pasta in your kitchen. Read more

Have you ever noticed that some objects tend to expand when they get hot, and contract when they cool down? For example, you might run hot water over the lid of a jar that's stuck - this causes the lid to expand, making it easier to twist off. Does this effect work the same way for all materials? Try this fun activity to find out! Read more

Test the Webb Space Telescope's Amazing Multiple Mirrors and Sunshield

Science Fair Project Idea

Scientific Method

Can you imagine designing and building a space telescope the size of a tennis court? Believe it or not, that is someone's job! Hundreds of engineers were involved in getting the James Webb Space Telescope (JWST) into space. This telescope has the potential to enable astronomers to see light from when the Universe was first formed. No one knows what amazing discoveries this might lead to, but already, JWST has delivered astounding deep space images that offer an unprecedented look at… Read more
