Investigate the 'Death' of an Orange: How is Rate of Heat Loss Based on the Surrounding Temperature?

Science Fair Project Idea

Scientific Method

Imagine that you are a detective investigating a murder. You have a body that was found in a swimming pool, and someone reported hearing an argument near the pool at 10:00 PM the night before. Your first question might be "Was this person killed around 10:00 PM last night, or at some other time?" One way to answer this question is to measure the internal temperature of the body. The longer ago the killing occurred, the colder the body. But can you assign a specific time of death to a specific… Read more

Have you ever watched an old movie, and when a character asks what time it is the other characters all look at the sky, instead of checking their watches, or their cell phones? There’s no giant digital clock in the sky, those characters are using the position of the Sun in the sky to tell time, as people have done for generations. The oldest known instruments for telling time, the sundial, allow us to track the position of the sun more accurately. Up until the early 19th century, sundials… Read more

Have you ever played with a Slinky, used a pinball machine, written with a click pen, or ridden in a car? If so, then you have used a spring. Springs are in machines all around us and have many useful purposes. In this activity you will learn how a spring can be used to make a scale to weigh objects. Read more

Making A Candy Waterfall: Can Solids Flow Like Liquids?

Science Fair Project Idea

Scientific Method

What do sand, Skittles, and cereal have in common? They are all granular materials, which means they are made up of solid particles, but they can actually flow like liquid! Imagine pouring the sand out of a bucket or pouring the cereal out of a box— a lot like pouring water, right? In this physics science project, you will investigate how the size of granular materials affect how they flow. Read more

Measuring the Surface Tension of Water

Science Fair Project Idea

Scientific Method

Did you know that when you dip your finger in water and pull it out, the water is actually pulling back on you? Here's a way you can measure how much. Read more

Mixing Mystery: Why Does Tumbling Sometimes Separate Mixtures?

Science Fair Project Idea

Scientific Method

What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container Read more

Motion Mania: Applying Physics to Hula-Hooping

Science Fair Project Idea

Scientific Method

Practice makes you better at most things, and knowledge makes practice so much easier! Can you swirl a circular toy called a hula hoop around your waist or arm? Is it hard? What knowledge can you apply to find ways that make hula-hooping easier? Physics! Yes, physics will help you determine what makes one hula hoop a winner and another a flop. In this project, you will create your own hula hoops, spin them, and draw conclusions. The road will then be open to your becoming a hula hoop expert. If… Read more

MrBeast "Protect the Prize" Challenge

Science Fair Project Idea

Engineering Design Process

MrBeast, the world's most famous YouTuber, has a series of challenge videos where he asks a contestant to protect some valuable prize - like a pile of money or an expensive car - from a series of attacks like explosions, giant fireballs launched from catapults, or even getting hit by a train! Contestants often have only 24 hours to build something to protect their prize, which presents a very interesting engineering challenge. Given limited time and access to materials, how can you best protect… Read more

Did you know that not all animals use their ears to ‘hear’ sounds? Snakes, for example, perceive sound waves through their jaw bones! And many insects perceive sound waves through their antennae. While these methods of detecting sound might be different, they all respond to the same thing that our ears do, which is sound waves in the environment. In this activity you will generate some impressive sound waves from very simple materials, and observe how these sound waves are… Read more
