Locating an Earthquake Using a Global Seismic Network

Science Fair Project Idea

Scientific Method

When an earthquake happens, how are scientists able to determine the original location of the quake? In this project, you'll use archived data from a global network of seismometers to find out for yourself. You will make your own seismograms using the Global Earthquake Explorer program, and then use the seismograms to determine the location of earthquake epicenters. Read more

Locating the Epicenter of an Earthquake

Science Fair Project Idea

Scientific Method

When an earthquake happens, how are scientists able to determine the original location of the quake? In this project, you'll use archived data from a network of seismometers to find out for yourself. You'll create your own seismograms from the comfort of your own computer with an easy-to-use webpage interface. Then you'll analyze your seismograms to determine the distance of the quake from each seismometer station. By mapping your analyzed data, you will be able to determine the location of the… Read more

Lung Capacity and Age

Science Fair Project Idea

Scientific Method

Our metabolism changes as we get older, a sad fact of life that we cannot change. Old age affects our bodies in many ways. Changes in musculature, bone strength, energy, diet and breathing are some of the many ways we change as we age. You might notice that people often get out of breath when they are older and doing a physical activity. Why do some people feel out of breath, while others do not? Does this change correlate with age? Could this reflect a difference in lung capacity between… Read more

Macroinvertebrates as Indicators of Pollution

Science Fair Project Idea

Scientific Method

In this science project, you will collect macroinvertebrate samples from multiple points along a body of water, ideally a small creek or stream, and test the pollution burden and biodiversity of small organisms or insects to see if pollution impacts biodiversity. Read more

Make a Magnetic Slime Robot

Science Fair Project Idea

Engineering Design Process

Could you use a magnetic slime "robot" to retrieve a battery accidentally swallowed by a small child? Scientists think so! Watch this video to learn about magnetic slime that, when driven by external magnetic fields, can squeeze through small spaces and even grasp objects. Can you make your own magnetic slime robot that can accomplish some of the same tasks demonstrated by the researchers? You can start by adding iron filings to slime to make your own magnetic slime (see this Science Buddies… Read more

Are your students passionate about the environment? Do they like to explore new ideas for more eco-friendly products? This lesson will give your students a chance to grow a product out of mycelium composite, a material that recently gained traction as an eco-friendly alternative for many plastics and foams. Students will analyze the impact of this product on the environment at every step of its life cycle, from raw material to the end of its life, and compare it to a plastic or cardboard… Read more

NGSS Performance Expectations:

HS-ESS3-4. Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

Make Soft Robotic Skin

Science Fair Project Idea

Engineering Design Process

When you think about robots, do you think of something made from metal? What if robots could have stretchy, flexible skin just like humans? How would they detect when someone tapped them on the shoulder or something rubbed against their arm? In this project, you will learn how to make artificial robotic skin using flexible rubber with an embedded conductive fabric. You can also connect the artificial skin to a microcontroller and use it to control outputs like LEDs or motors. Read more

Maybe you have grown vegetables or flowers, but have you ever grown the flowerpot? Yes, you read that right! In this activity, you will use mushroom roots to grow a biodegradable material that can be molded into a product of your liking, like a flowerpot! Growing a set of bowls, a lampshade, or a pot is easier than you might think. Once you try it out, you just might feel inspired to replace some of your plastic objects with ecological counterparts that you created from mushroom roots! Read more

Making Jell-o Stronger

Science Fair Project Idea

Scientific Method

Gelatin! It's hard to think of another food that is used as frequently on the dinner table as off. You can find it in all sorts of sweet foods, from ice cream, yogurt, and gummy bears, to marshmallows and yellow colorings for sodas. Off the table, it shows up in glues, photographic paper, playing cards, crepe paper, medicine capsules, hair gels, and professional lighting equipment. From the kitchen to the theater—what a range of uses! In this cooking and food science fair project, you'll… Read more

Making Milk Curdle with Pineapple Enzymes

Science Fair Project Idea

Scientific Method

Have you ever gone to pour yourself a cup of milk and all you get is milk clumps? What happened to the milk is called coagulation, which is the mechanism that occurs when proteins in the milk clump together. While you do not necessarily want this in your milk, without coagulation (or curdling), there would not be any cheese or yogurt, which is why it is a very important process in the food industry. But what makes milk curdle? In this science project you will use pineapple juice to curdle milk… Read more
